Abstract In this paper the execution time is less when compared to previous algorithm. And also it provide security between the merchant and buyer The traitor tracing protocol is used to detect the illegal transaction. Here we used fingerprinting solution to avoid illegal redistribution of multimedia contents. Here we convert the multimedia video file into image then encrypting the image after the encrypted image will be transferred from merchant to buyer. The buyer receives the copyright protection from merchant, he decrypts the image then converts it into video. After that, the copyright protection of file is transferred to child buyer. Then tracing traitor protocol is used to checks the fingerprints for merchant to buyer and buyer to child buyer. Traitor tracing protocol is used to detect the illegal transaction of the content. The Blowfish algorithm is used to encrypt and decrypt the multimedia files. Finally we detect the performance of our work based on efficiency, accuracy and we achieve security.

Information Leakage Prevention Using Public Key Encryption System and Fingerp...CSCJournals
The increase in the use of the internet around the world provided easier way of communication and information sharing that has led to the huge challenge of data leakage on the network. In an academic environment such as higher institutions of learning, the need to ensure that access to data and sensitive information are given to authorized users become imperative. However, this is not always the case as security bridges are often experienced. This study proposed a RSA public key encryption system and biometric fingerprint augmented with Apriori algorithm to prevent information leakages. The fingerprint verifies the identity of the owner of incoming message and the Apriori algorithm is used as the detection system instead of biometric that requires additional hardware for detecting fingerprint. This study developed a system based on the proposed algorithm. The developed system was tested on Federal Polytechnic, Ilaro local area network achieving a high level of security that prevents interception of valuable data by intruders or eavesdroppers. The system developed RSA public key encryption and fingerprint augmented with Apriori algorithm thus provided the required security mechanism that prevents information leakage in a public environment.
Control Cloud Data Access Using Attribute-Based Encryptionpaperpublications3
Abstract: Cloud computing is a revolutionary computing paradigm which enables flexible, on-demand and low-cost usage of computing resources. Those advantages, ironically, are the causes of security and privacy problems, which emerge because the data owned by different users are stored in some cloud servers instead of under their own control. To deal with security problems, various schemes based on the Attribute-Based Encryption have been proposed recently. Data access control is an effective way to ensure the data security in the cloud. However, due to data outsourcing and untrusted cloud servers, the data access control becomes a challenging issue in cloud storage systems. Data security is the key concern in the distributed system. Various schemes based on the attribute-based encryption have been proposed to secure the cloud storage. However, most work focuses on the data contents privacy and the access control, while less attention is paid to the privilege control and the identity privacy. In this paper, we present a semianonymous privilege control scheme AnonyControl to address not only the data privacy, but also the user identity privacy in existing access control schemes. AnonyControl decentralizes the central authority to limit the identity leakage and thus achieves semianonymity. Besides, it also generalizes the file access control to the privilege control, by which privileges of all operations on the cloud data can be managed in a fine-grained manner. Subsequently, we present the AnonyControl-F, which fully prevents the identity leakage and achieve the full anonymity. Our security analysis shows that both AnonyControl and AnonyControl-F are secure under the decisional bilinear Diffie–Hellman assumption, and our performance evaluation exhibits the feasibility of our schemes.
A Location Based Cryptosystem For Mobile Devices Using Improved Rabin AlgorithmEditor IJMTER
As per the recent studies, the volatile growth has been seen in the use of mobile devices as
the supporting technology for accessing Internet based services, as well as for personal
communication needs in networking. Various studies indicate that it is impossible to utilize strong
cryptographic functions for implementing security protocols on mobile devices. Our research negates
this. Explicitly, a performance analysis focused on the most commonly used cryptographic protocols
based on the location address (latitude & longitude) of the user for mobile applications and projected
provably secure authentication protocol that is more efficient than any of the prevailing
authentication protocol is being used by the network security methods. Understanding the use of
public key cryptography which makes potential use of discrete logarithms problem. The security of
ECC depends on the difficulty of Elliptic Curve Discrete Logarithm. To provide secure
communication for mobile devices, authenticated protocol is an important primitive for establishing
trusted connection. In this paper, it has been shown that the location based system using improved
Rabin Algorithm provides a better security and acquires much less energy consumption than the
existing authentication protocols.
Instant Messenger (IM) becomes one of the most popular applications in mobile technology and
communication. A lot of users around the world installed it for daily activities. Current IM found security
lacks both in authentication and encryption matters. Various IM growing today still not apply an efficient
method in authentication and encryption process, conventional security methods and client-server
architecture system have to risk too many users for attacking server such as compromising, cracking
password or PINs by Unauthorized people. Common IM services lack native encryption to protect
information being transmitted over the public network and still used high computation in the mobile
environment, this problem needs efficient security methods. Then, in public IM also found various
messages with fake users, it occurs because public IM carry out the separate system in authentication and
encryption process, strong authentication need to solve this issue in messenger environment. The
tremendous growth of mobile IM user needs efficient and secure communication way. This paper proposes
a new efficient method for securing message both in encryption and authentication within the end-to-end
model. In this research, security method proposes new algorithms based on Elliptic Curve (EC) works in
Peer to Peer (P2P) architecture than a conventional client-server model. The result shows this method
produces efficient time in authentication and encryption process while applying in a mobile environment.
Besides, it is compatible with the mobile phone which has a limitation of computation capabilities and
resources.

Abstract: This paper builds an algorithm for sharing simple integer data on top of secure sum data mining operation using Newton’s identities and Sturm’s theorem. Algorithm for anonymous sharing of private data among parties is developed. This assignment is anonymous in that the identities received are unknown to the other members of the group. Resistance to collusion among other members is verified in an information theoretic sense when private communication channels are used. This assignment of serial numbers allows more complex data to be shared and has applications to other problems in privacy preserving data mining, collision avoidance in communications and distributed database access. The new algorithms are built on top of a secure sum data mining operation using Newton’s identities and Sturm’s theorem. An algorithm for distributed solution of certain polynomials over finite fields enhances the scalability of the algorithms.

Security Aspects of the Information Centric Networks ModelCSCJournals
With development of internet and the enormous growth of contents over networks, that motivated the researchers to proposed new paradigm model called Information Centric Networks ICN , the most features of ICN model is based on the content itself, instead, of the server located the contents over internet. This new model has a lot of challenges such as, mobility of contents, naming, replications, cashing, communications, and the security issue to secure the contents, customer, and providers. In this paper we will focus on ICN Model and propose solutions of security to protect the network elements, since the security is based on the packet itself rather than the host-centric.
A Self –Destructing Secure Messaging System Using Multi Key Management Schemeijiert bestjournal
We propose the Pandora Messaging, an enhanced secure instant messaging architecture which is
equipped with a self-message-destructing feature for sensitive personal information applications
in a mobile environment along with Multi Key Security Management using Shamirs algorithm.
The proposed system will be beneficial for Government officers for communicating very
sensitive and confidential messages. We design the Pandora Message Encryption and Exchange
Scheme and the format of a self-destructible message to show how to exchange these messages
atop the existing instant messaging service architecture. The Pandora Messaging-based system
enables senders to set time, frequency, and location constraints. These conditions determine
when the transmitted messages should be destructed and thus become unreadable for receivers.
The Pandora Messaging-based system securely sends self destructible messages to receivers in a
way that it uses ephemeral keys to encrypt the messages and transmits the encrypted messages to
the designated receiver‟s instant messaging service in real time. When the transmitted messages‟
constraints are satisfied, the ephemeral key used for encryption will be deleted .Thus, the
encrypted messages become unrecoverable. The most important part is that the Key are managed
by the system. The system generates a pool of key and any group of the same pool can be used to
encrypt and decrypt the message.
Distributed Digital Artifacts on the Semantic WebEditor IJCATR
Distributed digital artifacts incorporate cryptographic hash values to URI called trusty URIs in a distributed environment
building good in quality, verifiable and unchangeable web resources to prevent the rising man in the middle attack. The greatest
challenge of a centralized system is that it gives users no possibility to check whether data have been modified and the communication
is limited to a single server. As a solution for this, is the distributed digital artifact system, where resources are distributed among
different domains to enable inter-domain communication. Due to the emerging developments in web, attacks have increased rapidly,
among which man in the middle attack (MIMA) is a serious issue, where user security is at its threat. This work tries to prevent MIMA
to an extent, by providing self reference and trusty URIs even when presented in a distributed environment. Any manipulation to the
data is efficiently identified and any further access to that data is blocked by informing user that the uniform location has been
changed. System uses self-reference to contain trusty URI for each resource, lineage algorithm for generating seed and SHA-512 hash
generation algorithm to ensure security. It is implemented on the semantic web, which is an extension to the world wide web, using
RDF (Resource Description Framework) to identify the resource. Hence the framework was developed to overcome existing
challenges by making the digital artifacts on the semantic web distributed to enable communication between different domains across
the network securely and thereby preventing MIMA.
A Survey on Enhancement of Text Security Using Steganography and Cryptographi...ijtsrd
Increase in the number of attack recorded during electronic exchange of information between the source and intended destination has indeed called for a more robust method for securing data transfer. Cryptography and steganography are well known and widely used techniques that manipulate information in order to cipher or hide their existence. Many different carrier file format scan be used but digital images are the most popular because of their frequency on the internet. The digital images are the most popular because of their frequency on the Web among all different carrier file formats. Image steganography, achieves the secrecy by embedding data into cover image and generating a stego-image. There are many types of steganography techniques each have their advantages and disadvantages. This paper discussed a technique used on the advanced LSB (least significant bit) and RSA algorithm. By matching data to an image, there is less chance of an attacker being able to use steganalysis to recover data. Before hiding the data in an image the application first encrypts it Priya Jain | Somesh Kumar | Raj Kumar Goel"A Survey on Enhancement of Text Security Using Steganography and Cryptographic Techniques" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-2 | Issue-5 , August 2018, URL: http://www.ijtsrd.com/papers/ijtsrd15800.pdf http://www.ijtsrd.com/computer-science/computer-security/15800/a-survey-on-enhancement-of-text-security-using--steganography-and-cryptographic-techniques/priya-jain
Augmenting Publish/Subscribe System by Identity Based Encryption (IBE) Techni...IJCERT JOURNAL
Security is one of the extensive and complicated requirements that need to be provided in order to achieve few issues like confidentiality, integrity and authentication. In a content-based publish/subscribe system, authentication is difficult to achieve since there exists no strong bonding between the end parties. Similarly, Integrity and confidentiality needs arise in published events and subscription conflicts with content-based routing. The basic tool to support confidentiality, integrity is encryption. In this paper for providing security mechanism in broker-less content-based publish/subscribe system we adapt pairing-based cryptography mechanism. In this mechanism, we use Identity Based Encryption (IBE) technique to achieve the needs of publish/subscribe system. This approach helps in providing fine-grained key management, effective encryption, decryption operations and routing is carried out in the order of subscribed attributes

Accessing secured data in cloud computing environmentIJNSA Journal
Number of businesses using cloud computing has increased dramatically over the last few years due to the attractive features such as scalability, flexibility, fast start-up and low costs. Services provided over the web are ranging from using provider’s software and hardware to managing security and other issues. Some of the biggest challenges at this point are providing privacy and data security to subscribers of public cloud servers. An efficient encryption technique presented in this paper can be used for secure access to and storage of data on public cloud server, moving and searching encrypted data through communication channels while protecting data confidentiality. This method ensures data protection against both external and internal intruders. Data can be decrypted only with the provided by the data owner key, while public cloud server is unable to read encrypted data or queries. Answering a query does not depend on it size and done in a constant time. Data access is managed by the data owner. The proposed schema allows unauthorized modifications detection
PROACTIVE DETECTION OF DDOS ATTACKS IN PUBLISH-SUBSCRIBE NETWORKSIJNSA Journal
Abstract. Information centric networking (ICN) using architectures such as Publish-Subscribe Internet
Routing Paradigm (PSIRP) or Publish-Subscribe Internet Technology (PURSUIT) has been proposed as an
important candidate for the Internet of the future. ICN is an emerging research area that proposes a
transformation of the current host centric Internet architecture into an architecture where information
items are of primary importance. This change allows network functions such as routing and locating to be
optimized based on the information items themselves. The Bloom filter based content delivery is a sourcerouting
scheme that is used in the PSIRP/PURSUIT architectures. Although this mechanism solves many
issues of today’s Internet such as the growth of the routing table and the scalability problems, it is
vulnerable to distributed denial-of-service (DDoS) attacks. In this paper, we present a new content delivery
scheme that has the advantages of Bloom filter based approach while at the same time being able to
prevent DDoS attacks on the forwarding mechanism. Our security analysis suggests that with the proposed
approach, the forwarding plane is able to resist attacks such as DDoS with very high probability.
USING A DEEP UNDERSTANDING OF NETWORK ACTIVITIES FOR SECURITY EVENT MANAGEMENTIJNSA Journal
With the growing deployment of host-based and network-based intrusion detection systems in increasingly
large and complex communication networks, managing low-level alerts from these systems becomes
critically important. Probes of multiple distributed firewalls (FWs), intrusion detection systems (IDSs) or
intrusion prevention systems (IPSs) are collected throughout a monitored network such that large series of
alerts (alert streams) need to be fused. An alert indicates an abnormal behavior, which could potentially be
a sign for an ongoing cyber attack. Unfortunately, in a real data communication network, administrators
cannot manage the large number of alerts occurring per second, in particular since most alerts are false
positives. Hence, an emerging track of security research has focused on alert correlation to better identify
true positive and false positive. To achieve this goal we introduce Mission Oriented Network Analysis
(MONA). This method builds on data correlation to derive network dependencies and manage security
events by linking incoming alerts to network dependencies.
Secure and privacy preserving data centric sensor networks with multi query o...eSAT Journals
Abstract
In large-scale Wireless Sensor Networks the effective use of the vast amounts of data gathered will require scalable, self-organizing, and energy-efficient data dissemination and data retrieval techniques. Data Centric Sensor (DCS) networks is a better approach in which the sensor nodes send the sensed data to a designated sensor node whose name is associated with sensed data. However, due to unattended nature of Wireless Sensor Networks, these sensor nodes are susceptible to different types of attacks. The attacker may compromise these storage nodes and get data of his interest. In this paper we propose a Secure and Privacy Preserving Data Centric Sensor Networks that includes security and privacy support to DCS networks. We use multi level key structure and cryptographic algorithms to provide security. In addition, we propose a multi-query optimization technique that aggregates similar queries for a small periodic time and construct a query message. This reduces the number of messages required to serve multiple similar queries. Simulation and experimental results show that our work provides a secure privacy preserving data centric sensor network based on cryptographic keys and reduces the message overhead and incurs a minimum communication cost compared to previous works

Digital watermarking provides authentication, validation and copyright protection for multimedia contents over the internet. Text is the most widely used means of communication in addition to image, audio and video. So it needs to be protected. Text watermarking techniques that have been developed in past protects the text from illegal copying, imitation, and prevents copyright violations. In this paper, we have proposed an algorithm that ensures the integrity and confidentiality of the document. In this technique watermark is created based on the contents of the document and embeds it without changing the contents of the document and also encrypts the text to provide confidentiality. To authenticate and prove the integrity of the document the watermark can be easily extracted and verified for tampering.
Cloud Security and Data Integrity with Client Accountability FrameworkIDES Editor
The Cloud based services provide much efficient
and seamless ways for data sharing across the cloud. The fact
that the data owners no longer possess data makes it very
difficult to assure data confidentiality and to enable secure
data sharing in the cloud. Despite of all its advantages this
will remain a major limitation that acts as a barrier to the
wider deployment of cloud based services. One of the possible
ways for ensuring trust in this aspect is the introduction of
accountability feature in the cloud computing scenario. The
Cloud framework requires promotion of distributed
accountability for such dynamic environment[1]. In some
works, there‘s an accountable framework suggested to ensure
distributed accountability for data sharing by the generation
of only a log of data access, but without any embedded feedback
mechanism for owner permission towards data
protection[2].The proposed system is an enhanced client
accountability framework which provides an additional client
side verification for each access towards enhanced security of
data. The integrity of content of data which resides in the
cloud service provider is also maintained by secured
outsourcing. Besides, the authentication of JAR(Java Archive)
files are done to ensure file protection and to maintain a safer
environment for data sharing. The analysis of various
functionalities of the framework depicts both the
accountability and security feature in an efficient manner.
Peer-to-Peer content distribution using automatically recombined fingerprintsIJERA Editor
Due to the recent advances in broad-band network and multimedia technologies, the distribution of multimedia
contents are increasing. This will help a malicious party to duplicate and redistribute the contents; hence the
protection of the ownership is required in multimedia content distribution. The encryption of content cannot
solve the issue, because it must be ultimately decrypted at genuine users who have legal authority to distribute
content. Therefore, additional protection mechanisms are needed to discourage unauthorized redistribution. One
of the mechanisms is to generate the fingerprinting of multimedia which enables a seller to trace illegal users by
embedding identification information into the content. The research on fingerprinting techniques is classified
into two studies: collusion resistant fingerprinting systems and cryptographic protocol. Since each user
download content with his/her own fingerprint and content is a little different. If users collect some of them,
they try to find the difference and modify/delete the embedded information. Unicast transmission is applied in
multimedia content distribution which will be give more security to buyers. Merchant will create number of seed
buyers who need to distribute the content to child buyers. All the seed buyers should be online to distribute the
content. The seed buyer and child buyer fingerprint are need to store in database which will be required to find
the illegal redistribution.

Abstract: This paper builds an algorithm for sharing simple integer data on top of secure sum data mining operation using Newton’s identities and Sturm’s theorem. Algorithm for anonymous sharing of private data among parties is developed. This assignment is anonymous in that the identities received are unknown to the other members of the group. Resistance to collusion among other members is verified in an information theoretic sense when private communication channels are used. This assignment of serial numbers allows more complex data to be shared and has applications to other problems in privacy preserving data mining, collision avoidance in communications and distributed database access. The new algorithms are built on top of a secure sum data mining operation using Newton’s identities and Sturm’s theorem. An algorithm for distributed solution of certain polynomials over finite fields enhances the scalability of the algorithms.

Security Aspects of the Information Centric Networks ModelCSCJournals
With development of internet and the enormous growth of contents over networks, that motivated the researchers to proposed new paradigm model called Information Centric Networks ICN , the most features of ICN model is based on the content itself, instead, of the server located the contents over internet. This new model has a lot of challenges such as, mobility of contents, naming, replications, cashing, communications, and the security issue to secure the contents, customer, and providers. In this paper we will focus on ICN Model and propose solutions of security to protect the network elements, since the security is based on the packet itself rather than the host-centric.
A Self –Destructing Secure Messaging System Using Multi Key Management Schemeijiert bestjournal
We propose the Pandora Messaging, an enhanced secure instant messaging architecture which is
equipped with a self-message-destructing feature for sensitive personal information applications
in a mobile environment along with Multi Key Security Management using Shamirs algorithm.
The proposed system will be beneficial for Government officers for communicating very
sensitive and confidential messages. We design the Pandora Message Encryption and Exchange
Scheme and the format of a self-destructible message to show how to exchange these messages
atop the existing instant messaging service architecture. The Pandora Messaging-based system
enables senders to set time, frequency, and location constraints. These conditions determine
when the transmitted messages should be destructed and thus become unreadable for receivers.
The Pandora Messaging-based system securely sends self destructible messages to receivers in a
way that it uses ephemeral keys to encrypt the messages and transmits the encrypted messages to
the designated receiver‟s instant messaging service in real time. When the transmitted messages‟
constraints are satisfied, the ephemeral key used for encryption will be deleted .Thus, the
encrypted messages become unrecoverable. The most important part is that the Key are managed
by the system. The system generates a pool of key and any group of the same pool can be used to
encrypt and decrypt the message.
Distributed Digital Artifacts on the Semantic WebEditor IJCATR
Distributed digital artifacts incorporate cryptographic hash values to URI called trusty URIs in a distributed environment
building good in quality, verifiable and unchangeable web resources to prevent the rising man in the middle attack. The greatest
challenge of a centralized system is that it gives users no possibility to check whether data have been modified and the communication
is limited to a single server. As a solution for this, is the distributed digital artifact system, where resources are distributed among
different domains to enable inter-domain communication. Due to the emerging developments in web, attacks have increased rapidly,
among which man in the middle attack (MIMA) is a serious issue, where user security is at its threat. This work tries to prevent MIMA
to an extent, by providing self reference and trusty URIs even when presented in a distributed environment. Any manipulation to the
data is efficiently identified and any further access to that data is blocked by informing user that the uniform location has been
changed. System uses self-reference to contain trusty URI for each resource, lineage algorithm for generating seed and SHA-512 hash
generation algorithm to ensure security. It is implemented on the semantic web, which is an extension to the world wide web, using
RDF (Resource Description Framework) to identify the resource. Hence the framework was developed to overcome existing
challenges by making the digital artifacts on the semantic web distributed to enable communication between different domains across
the network securely and thereby preventing MIMA.
A Survey on Enhancement of Text Security Using Steganography and Cryptographi...ijtsrd
Increase in the number of attack recorded during electronic exchange of information between the source and intended destination has indeed called for a more robust method for securing data transfer. Cryptography and steganography are well known and widely used techniques that manipulate information in order to cipher or hide their existence. Many different carrier file format scan be used but digital images are the most popular because of their frequency on the internet. The digital images are the most popular because of their frequency on the Web among all different carrier file formats. Image steganography, achieves the secrecy by embedding data into cover image and generating a stego-image. There are many types of steganography techniques each have their advantages and disadvantages. This paper discussed a technique used on the advanced LSB (least significant bit) and RSA algorithm. By matching data to an image, there is less chance of an attacker being able to use steganalysis to recover data. Before hiding the data in an image the application first encrypts it Priya Jain | Somesh Kumar | Raj Kumar Goel"A Survey on Enhancement of Text Security Using Steganography and Cryptographic Techniques" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-2 | Issue-5 , August 2018, URL: http://www.ijtsrd.com/papers/ijtsrd15800.pdf http://www.ijtsrd.com/computer-science/computer-security/15800/a-survey-on-enhancement-of-text-security-using--steganography-and-cryptographic-techniques/priya-jain
Augmenting Publish/Subscribe System by Identity Based Encryption (IBE) Techni...IJCERT JOURNAL
Security is one of the extensive and complicated requirements that need to be provided in order to achieve few issues like confidentiality, integrity and authentication. In a content-based publish/subscribe system, authentication is difficult to achieve since there exists no strong bonding between the end parties. Similarly, Integrity and confidentiality needs arise in published events and subscription conflicts with content-based routing. The basic tool to support confidentiality, integrity is encryption. In this paper for providing security mechanism in broker-less content-based publish/subscribe system we adapt pairing-based cryptography mechanism. In this mechanism, we use Identity Based Encryption (IBE) technique to achieve the needs of publish/subscribe system. This approach helps in providing fine-grained key management, effective encryption, decryption operations and routing is carried out in the order of subscribed attributes

Accessing secured data in cloud computing environmentIJNSA Journal
Number of businesses using cloud computing has increased dramatically over the last few years due to the attractive features such as scalability, flexibility, fast start-up and low costs. Services provided over the web are ranging from using provider’s software and hardware to managing security and other issues. Some of the biggest challenges at this point are providing privacy and data security to subscribers of public cloud servers. An efficient encryption technique presented in this paper can be used for secure access to and storage of data on public cloud server, moving and searching encrypted data through communication channels while protecting data confidentiality. This method ensures data protection against both external and internal intruders. Data can be decrypted only with the provided by the data owner key, while public cloud server is unable to read encrypted data or queries. Answering a query does not depend on it size and done in a constant time. Data access is managed by the data owner. The proposed schema allows unauthorized modifications detection
PROACTIVE DETECTION OF DDOS ATTACKS IN PUBLISH-SUBSCRIBE NETWORKSIJNSA Journal
Abstract. Information centric networking (ICN) using architectures such as Publish-Subscribe Internet
Routing Paradigm (PSIRP) or Publish-Subscribe Internet Technology (PURSUIT) has been proposed as an
important candidate for the Internet of the future. ICN is an emerging research area that proposes a
transformation of the current host centric Internet architecture into an architecture where information
items are of primary importance. This change allows network functions such as routing and locating to be
optimized based on the information items themselves. The Bloom filter based content delivery is a sourcerouting
scheme that is used in the PSIRP/PURSUIT architectures. Although this mechanism solves many
issues of today’s Internet such as the growth of the routing table and the scalability problems, it is
vulnerable to distributed denial-of-service (DDoS) attacks. In this paper, we present a new content delivery
scheme that has the advantages of Bloom filter based approach while at the same time being able to
prevent DDoS attacks on the forwarding mechanism. Our security analysis suggests that with the proposed
approach, the forwarding plane is able to resist attacks such as DDoS with very high probability.
USING A DEEP UNDERSTANDING OF NETWORK ACTIVITIES FOR SECURITY EVENT MANAGEMENTIJNSA Journal
With the growing deployment of host-based and network-based intrusion detection systems in increasingly
large and complex communication networks, managing low-level alerts from these systems becomes
critically important. Probes of multiple distributed firewalls (FWs), intrusion detection systems (IDSs) or
intrusion prevention systems (IPSs) are collected throughout a monitored network such that large series of
alerts (alert streams) need to be fused. An alert indicates an abnormal behavior, which could potentially be
a sign for an ongoing cyber attack. Unfortunately, in a real data communication network, administrators
cannot manage the large number of alerts occurring per second, in particular since most alerts are false
positives. Hence, an emerging track of security research has focused on alert correlation to better identify
true positive and false positive. To achieve this goal we introduce Mission Oriented Network Analysis
(MONA). This method builds on data correlation to derive network dependencies and manage security
events by linking incoming alerts to network dependencies.
Secure and privacy preserving data centric sensor networks with multi query o...eSAT Journals
Abstract
In large-scale Wireless Sensor Networks the effective use of the vast amounts of data gathered will require scalable, self-organizing, and energy-efficient data dissemination and data retrieval techniques. Data Centric Sensor (DCS) networks is a better approach in which the sensor nodes send the sensed data to a designated sensor node whose name is associated with sensed data. However, due to unattended nature of Wireless Sensor Networks, these sensor nodes are susceptible to different types of attacks. The attacker may compromise these storage nodes and get data of his interest. In this paper we propose a Secure and Privacy Preserving Data Centric Sensor Networks that includes security and privacy support to DCS networks. We use multi level key structure and cryptographic algorithms to provide security. In addition, we propose a multi-query optimization technique that aggregates similar queries for a small periodic time and construct a query message. This reduces the number of messages required to serve multiple similar queries. Simulation and experimental results show that our work provides a secure privacy preserving data centric sensor network based on cryptographic keys and reduces the message overhead and incurs a minimum communication cost compared to previous works

Study, analysis and formulation of a new method for integrity protection of d...ijsrd.com
Digital watermarking provides authentication, validation and copyright protection for multimedia contents over the internet. Text is the most widely used means of communication in addition to image, audio and video. So it needs to be protected. Text watermarking techniques that have been developed in past protects the text from illegal copying, imitation, and prevents copyright violations. In this paper, we have proposed an algorithm that ensures the integrity and confidentiality of the document. In this technique watermark is created based on the contents of the document and embeds it without changing the contents of the document and also encrypts the text to provide confidentiality. To authenticate and prove the integrity of the document the watermark can be easily extracted and verified for tampering.
Cloud Security and Data Integrity with Client Accountability FrameworkIDES Editor
The Cloud based services provide much efficient
and seamless ways for data sharing across the cloud. The fact
that the data owners no longer possess data makes it very
difficult to assure data confidentiality and to enable secure
data sharing in the cloud. Despite of all its advantages this
will remain a major limitation that acts as a barrier to the
wider deployment of cloud based services. One of the possible
ways for ensuring trust in this aspect is the introduction of
accountability feature in the cloud computing scenario. The
Cloud framework requires promotion of distributed
accountability for such dynamic environment[1]. In some
works, there‘s an accountable framework suggested to ensure
distributed accountability for data sharing by the generation
of only a log of data access, but without any embedded feedback
mechanism for owner permission towards data
protection[2].The proposed system is an enhanced client
accountability framework which provides an additional client
side verification for each access towards enhanced security of
data. The integrity of content of data which resides in the
cloud service provider is also maintained by secured
outsourcing. Besides, the authentication of JAR(Java Archive)
files are done to ensure file protection and to maintain a safer
environment for data sharing. The analysis of various
functionalities of the framework depicts both the
accountability and security feature in an efficient manner.
Peer-to-Peer content distribution using automatically recombined fingerprintsIJERA Editor
Due to the recent advances in broad-band network and multimedia technologies, the distribution of multimedia
contents are increasing. This will help a malicious party to duplicate and redistribute the contents; hence the
protection of the ownership is required in multimedia content distribution. The encryption of content cannot
solve the issue, because it must be ultimately decrypted at genuine users who have legal authority to distribute
content. Therefore, additional protection mechanisms are needed to discourage unauthorized redistribution. One
of the mechanisms is to generate the fingerprinting of multimedia which enables a seller to trace illegal users by
embedding identification information into the content. The research on fingerprinting techniques is classified
into two studies: collusion resistant fingerprinting systems and cryptographic protocol. Since each user
download content with his/her own fingerprint and content is a little different. If users collect some of them,
they try to find the difference and modify/delete the embedded information. Unicast transmission is applied in
multimedia content distribution which will be give more security to buyers. Merchant will create number of seed
buyers who need to distribute the content to child buyers. All the seed buyers should be online to distribute the
content. The seed buyer and child buyer fingerprint are need to store in database which will be required to find
the illegal redistribution.

PRIVACY AWARE COMPUTING
Introduction
With the increasing public concerns of security and personal data privacy worldwide, security
and privacy become an important research area. This research area is very broad and covers
many application domains.
The security and privacy aware computing research group actually focuses on
(1) privacy-preserved computing,
(2) Video surveillance, and
(3) secure biometric system.
Now let us briefly discuss the above three groups.
Privacy-preserved Computing
Concerns on the data privacy have been increasing worldwide. For example, Apple was
reportedly fined by South Korea’s telecommunications regulator for allegedly collecting and
storing private location data of iPhone users. The privacy concerns raised by both end-users and
government authorities have been hindering the deployment of many valuable IT services, such
as data mining and analysis, data outsourcing, and mobile location-aware computing.
soo, in response to the growing necessity of protecting data privacy, our research group has been
focusing on developing innovative solutions towards information services --- to support these
services while preserving users’ personal privacy.
Video Surveillance
With the growing installation of surveillance video cameras in both private and public areas, the
closed-circuit TV (CCTV) has been evolved from a single camera system to a multiple camera
system; and has recently been extended to a large-scale network of cameras.
One of the objectives of a camera network is to monitor and understand security issues in the
area under surveillance. While the camera network hardware is generally well-designed and
roundly installed, the development of intelligent video analysis software lags far behind. As
such, our group has been focusing on developing video surveillance algorithms such as face
tracking, person re-identification, human action recognition.
Our goal is to develop an intelligent video surveillance system.
Secure Biometric System
With the growing use of biometrics, there is a rising concern about the security and privacy of
the biometric data. Recent studies show that simple attacks on a biometric system, such as hill
climbing, are able to recover the raw biometric data from stolen biometric template. Moreover,
the attacker may be able to make use of the stolen face template to access the system or cross-
match across databases. Our group has been working on face template protection, multimodality
template protection, and .

- Security is a concept similar to being cautious
or alert against any danger. Network security is the condition of
being protected against any danger or loss. Thus safety plays a
important role in bank transactions where disclosure of any data
results in big loss. We can define networking as the combination
of two or more computers for the purpose of resource sharing.
Resources here include files, database, emails etc. It is the
protection of these resources from unauthorized users that
brought the development of network security. It is a measure
incorporated to protect data during their transmission and also
to ensure the transmitted is protected and authentic.
Security of online bank transactions here has been
improved by increasing the number of bits while establishing the
SSL connection as well as in RSA asymmetric key encryption
along with SHA1 used for digital signature to authenticate the
user

Cryptographic Methods:
Cryptography is the science of concealing information or encrypting information. Computers use complex cryptographic algorithms to enable data protection, data hiding, integrity checks, nonrepudiation services, policy enforcement, key management, and exchange, and many more (Conklin, 2018). Cryptography is classified into three types symmetric cryptography, asymmetric cryptography, and hash functions
Symmetric cryptography is also known as secret-key cryptography. It uses a single key to encrypt and decrypt data making it the simplest type of cryptography. A plain text with the key produces the same cipher similarly, the ciphertext with the key produces the plain text. "Symmetric encryption is useful for protecting data between parties with an established shared key and is also frequently used to store confidential data" (Burnett & Foster, 2004). This type of cryptography is suited for bulk encryption as it is fast and easy.
Asymmetric cryptography is also known as public-key cryptography. In this method, two keys are used to encrypt data. One for encoding and the other for decoding. One of the two keys stays private while the other is shared. The algorithms are based on integer factorization and discrete logarithmic problems. This encryption method is used for authentication and confidentiality.
The hash function is a special mathematical function. It performs a one-way function, which means that once the algorithm is processed, there is no feasible way to use the ciphertext to retrieve the plaintext that was used to generate it (Conklin, 2018). Hashes provide confidentiality but not integrity because even though we cannot determine the original text, we can ascertain the modified text. These are utilized in programs, text messages, and operating systems files.
Public Key Infrastructure (PKI):
It is an infrastructure that enables users to communicate securely. PKI uses the asymmetric method; one private key and one public key. The public key can only decrypt the file encrypted by the private key, which affirms the receiver and the sender's information is secure during a transaction. The challenges PKI face is the storage and protection of the keys. The encryption keys can be stolen or unrecoverable based on the measures taken to store them. Additionally, failure to issue and renew certificates can cause large-scale connectivity issues.
Physical Security:
Physical security needs to be maintained to prevent attackers from gaining access to steal data. Physical security is essential in an organization to prevent unauthorized individuals from causing harm to the business. If systems and devices are physically accessed, all files, data, information, and networks can be compromised. Granting limited access to employees to computer rooms or server rooms can prevent theft and help with intentional and unintentional damages. Perimeter security is also important, especially for sites ...

SECURITY PROPERTIES IN AN OPEN PEER-TO-PEER NETWORKIJNSA Journal
This paper proposes to address new requirements of confidentiality, integrity and availability properties fitting to peer-to-peer domains of resources. The enforcement of security properties in an open peer-topeer network remains an open problem as the literature have mainly proposed contribution on availability of resources and anonymity of users. That paper proposes a novel architecture that eases the administration of a peer-to-peer network. It considers a network of safe peer-to-peer clients in the sense that it is a commune client software that is shared by all the participants to cope with the sharing of various resources associated with different security requirements. However, our proposal deals with possible malicious peers that attempt to compromise the requested security properties. Despite the safety of an open peer-to-peer network cannot be formally guaranteed, since a end user has privileges on the target host, our solution provides several advanced security enforcement. First, it enables to formally define the requested security properties of the various shared resources. Second, it evaluates the trust and the reputation of the requesting peer by sending challenges that test the fairness of its peer-to-peer security policy. Moreover, it proposes an advanced Mandatory Access Control that enforces the required peer-to-peer security properties through an automatic projection of the requested properties onto SELinux policies. Thus, the SELinux system of the requesting peer is automatically configured with respect to the required peer-to-peer security properties. That solution prevents from a malicious peer that could use ordinary applications such as a video reader to access confidential files such as a video requesting fee paying. Since the malicious peer could try to abuse the system, SELinux challenges and traces are also used to evaluate the fairness of the requester. That paper ends with different research perspectives such as a dedicated MAC system for the peer-to-peer client and honeypots for testing the security of the proposed peer-to-peer infrastructure.

Material management in construction – a case studyeSAT Journals
Abstract
The objective of the present study is to understand about all the problems occurring in the company because of improper application
of material management. In construction project operation, often there is a project cost variance in terms of the material, equipments,
manpower, subcontractor, overhead cost, and general condition. Material is the main component in construction projects. Therefore,
if the material management is not properly managed it will create a project cost variance. Project cost can be controlled by taking
corrective actions towards the cost variance. Therefore a methodology is used to diagnose and evaluate the procurement process
involved in material management and launch a continuous improvement was developed and applied. A thorough study was carried
out along with study of cases, surveys and interviews to professionals involved in this area. As a result, a methodology for diagnosis
and improvement was proposed and tested in selected projects. The results obtained show that the main problem of procurement is

Life cycle cost analysis of overlay for an urban road in bangaloreeSAT Journals
Abstract
Pavements are subjected to severe condition of stresses and weathering effects from the day they are constructed and opened to traffic
mainly due to its fatigue behavior and environmental effects. Therefore, pavement rehabilitation is one of the most important
components of entire road systems. This paper highlights the design of concrete pavement with added mono fibers like polypropylene,
steel and hybrid fibres for a widened portion of existing concrete pavement and various overlay alternatives for an existing
bituminous pavement in an urban road in Bangalore. Along with this, Life cycle cost analyses at these sections are done by Net
Present Value (NPV) method to identify the most feasible option. The results show that though the initial cost of construction of
concrete overlay is high, over a period of time it prove to be better than the bituminous overlay considering the whole life cycle cost.
The economic analysis also indicates that, out of the three fibre options, hybrid reinforced concrete would be economical without
compromising the performance of the pavement.

Laboratory studies of dense bituminous mixes ii with reclaimed asphalt materialseSAT Journals
Abstract
The issue of growing demand on our nation’s roadways over that past couple of decades, decreasing budgetary funds, and the need to
provide a safe, efficient, and cost effective roadway system has led to a dramatic increase in the need to rehabilitate our existing
pavements and the issue of building sustainable road infrastructure in India. With these emergency of the mentioned needs and this
are today’s burning issue and has become the purpose of the study.
In the present study, the samples of existing bituminous layer materials were collected from NH-48(Devahalli to Hassan) site.The
mixtures were designed by Marshall Method as per Asphalt institute (MS-II) at 20% and 30% Reclaimed Asphalt Pavement (RAP).
RAP material was blended with virgin aggregate such that all specimens tested for the, Dense Bituminous Macadam-II (DBM-II)
gradation as per Ministry of Roads, Transport, and Highways (MoRT&H) and cost analysis were carried out to know the economics.
Laboratory results and analysis showed the use of recycled materials showed significant variability in Marshall Stability, and the
variability increased with the increase in RAP content. The saving can be realized from utilization of recycled materials as per the
methodology, the reduction in the total cost is 19%, 30%, comparing with the virgin mixes.

Laboratory investigation of expansive soil stabilized with natural inorganic ...eSAT Journals
Abstract
Soil stabilization has proven to be one of the oldest techniques to improve the soil properties. Literature review conducted revealed
that uses of natural inorganic stabilizers are found to be one of the best options for soil stabilization. In this regard an attempt has
been made to evaluate the influence of RBI-81 stabilizer on properties of black cotton soil through laboratory investigations. Black
cotton soil with varying percentages of RBI-81 viz., 0, 0.5, 1, 1.5, 2, and 2.5 percent were studied for moisture density relationships
and strength behaviour of soils. Also the effect of curing period was evaluated as literature review clearly emphasized the strength
gain of soils stabilized with RBI-81 over a period of time. The results obtained shows that the unconfined compressive strength of
specimens treated with RBI-81 increased approximately by 250% for a curing period of 28 days as compared to virgin soil. Further
the CBR value improved approximately by 400%. The studies indicated an increasing trend for soil strength behaviour with
increasing percentage of RBI-81 suggesting its potential applications in soil stabilization.
Influence of reinforcement on the behavior of hollow concrete block masonry p...eSAT Journals
Abstract
Reinforced masonry was developed to exploit the strength potential of masonry and to solve its lack of tensile strength. Experimental
and analytical studies have been carried out to investigate the effect of reinforcement on the behavior of hollow concrete block
masonry prisms under compression and to predict ultimate failure compressive strength. In the numerical program, three dimensional
non-linear finite elements (FE) model based on the micro-modeling approach is developed for both unreinforced and reinforced
masonry prisms using ANSYS (14.5). The proposed FE model uses multi-linear stress-strain relationships to model the non-linear
behavior of hollow concrete block, mortar, and grout. Willam-Warnke’s five parameter failure theory has been adopted to model the
failure of masonry materials. The comparison of the numerical and experimental results indicates that the FE models can successfully
capture the highly nonlinear behavior of the physical specimens and accurately predict their strength and failure mechanisms.

Influence of compaction energy on soil stabilized with chemical stabilizereSAT Journals
Abstract
Increase in traffic along with heavier magnitude of wheel loads cause rapid deterioration in pavements. There is a need to improve
density, strength of soil subgrade and other pavement layers. In this study an attempt is made to improve the properties of locally
available loamy soil using twin approaches viz., i) increasing the compaction of soil and ii) treating the soil with chemical stabilizer.
Laboratory studies are carried out on both untreated and treated soil samples compacted by different compaction efforts. Studies
show that increase in compaction effort results in increase in density of soil. However in soil treated with chemical stabilizer, rate of
increase in density is not significant. The soil treated with chemical stabilizer exhibits improvement in both strength and performance
properties.

Abstract
Water resources projects are inherited with overlapping and at times conflicting objectives. These projects are often of varied sizes
ranging from major projects with command areas of millions of hectares to very small projects implemented at the local level. Thus,
in all these projects there is seldom proper coordination which is essential for ensuring collective sustainability.
Integrated watershed development and management is the accepted answer but in turn requires a comprehensive framework that can
enable planning process involving all the stakeholders at different levels and scales is compulsory. Such a unified hydrological
framework is essential to evaluate the cause and effect of all the proposed actions within the drainage basins.
The present paper describes a hydrological framework developed in the form of a Hydrologic Information System (HIS) which is
intended to meet the specific information needs of the various line departments of a typical State connected with water related aspects.
The HIS consist of a hydrologic information database coupled with tools for collating primary and secondary data and tools for
analyzing and visualizing the data and information. The HIS also incorporates hydrological model base for indirect assessment of
various entities of water balance in space and time. The framework would be maintained and updated to reflect fully the most
accurate ground truth data and the infrastructure requirements for planning and management.

Evaluation of punching shear in flat slabseSAT Journals
Abstract
Flat-slab construction has been widely used in construction today because of many advantages that it offers. The basic philosophy in
the design of flat slab is to consider only gravity forces; this method ignores the effect of punching shear due to unbalanced moments
at the slab column junction which is critical. An attempt has been made to generate generalized design sheets which accounts both
punching shear due to gravity loads and unbalanced moments for cases (a) interior column; (b) edge column (bending perpendicular
to shorter edge); (c) edge column (bending parallel to shorter edge); (d) corner column. These design sheets are prepared as per
codal provisions of IS 456-2000. These design sheets will be helpful in calculating the shear reinforcement to be provided at the
critical section which is ignored in many design offices. Apart from its usefulness in evaluating punching shear and the necessary
shear reinforcement, the design sheets developed will enable the designer to fix the depth of flat slab during the initial phase of the
design.

Estimation of surface runoff in nallur amanikere watershed using scs cn methodeSAT Journals
Abstract
The development of watershed aims at productive utilization of all the available natural resources in the entire area extending from
ridge line to stream outlet. The per capita availability of land for cultivation has been decreasing over the years. Therefore, water and
the related land resources must be developed, utilized and managed in an integrated and comprehensive manner. Remote sensing and
GIS techniques are being increasingly used for planning, management and development of natural resources. The study area, Nallur
Amanikere watershed geographically lies between 110 38’ and 110 52’ N latitude and 760 30’ and 760 50’ E longitude with an area of
415.68 Sq. km. The thematic layers such as land use/land cover and soil maps were derived from remotely sensed data and overlayed
through ArcGIS software to assign the curve number on polygon wise. The daily rainfall data of six rain gauge stations in and around
the watershed (2001-2011) was used to estimate the daily runoff from the watershed using Soil Conservation Service - Curve Number
(SCS-CN) method. The runoff estimated from the SCS-CN model was then used to know the variation of runoff potential with different
land use/land cover and with different soil conditions.

Abstract The nonlinear Static procedure also well known as pushover analysis is method where in monotonically increasing loads are applied to the structure till the structure is unable to resist any further load. It is a popular tool for seismic performance evaluation of existing and new structures. In literature lot of research has been carried out on conventional pushover analysis and after knowing deficiency efforts have been made to improve it. But actual test results to verify the analytically obtained pushover results are rarely available. It has been found that some amount of variation is always expected to exist in seismic demand prediction of pushover analysis. Initial study is carried out by considering user defined hinge properties and default hinge length. Attempt is being made to assess the variation of pushover analysis results by considering user defined hinge properties and various hinge length formulations available in literature and results compared with experimentally obtained results based on test carried out on a G+2 storied RCC framed structure. For the present study two geometric models viz bare frame and rigid frame model is considered and it is found that the results of pushover analysis are very sensitive to geometric model and hinge length adopted.

Abstract
Depletion of natural resources and aggregate quarries for the road construction is a serious problem to procure materials. Hence
recycling or reuse of material is beneficial. On emphasizing development in sustainable construction in the present era, recycling of
asphalt pavements is one of the effective and proven rehabilitation processes. For the laboratory investigations reclaimed asphalt
pavement (RAP) from NH-4 and crumb rubber modified binder (CRMB-55) was used. Foundry waste was used as a replacement to
conventional filler. Laboratory tests were conducted on asphalt concrete mixes with 30, 40, 50, and 60 percent replacement with RAP.
These test results were compared with conventional mixes and asphalt concrete mixes with complete binder extracted RAP
aggregates. Mix design was carried out by Marshall Method. The Marshall Tests indicated highest stability values for asphalt
concrete (AC) mixes with 60% RAP. The optimum binder content (OBC) decreased with increased in RAP in AC mixes. The Indirect
Tensile Strength (ITS) for AC mixes with RAP also was found to be higher when compared to conventional AC mixes at 300C.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

1. INTRODUCTION
Network security consists of the provisions and policies
adopted by a network administrator to prevent and monitor
unauthorized access, misuse, modification, or denial of a
computer network and network-accessible resources.
Network security involves the authorization of access to
data in a network, which is controlled by the network
administrator. Users choose or are assigned an ID and
password or other authenticating information that allows
them access to information and programs within their
authority. Network security covers a variety of computer
networks, both public and private, that are used in everyday
jobs conducting transactions and communications among
businesses, government agencies and individuals. Networks
can be private, such as within a company, and others which
might be open to public access. Network security is
involved in organizations, enterprises, and other types of
institutions.
It does as its title explains: It secures the network, as well as
protecting and overseeing operations being done. The most
common and simple way of protecting a network resource is
by assigning it a unique name and a corresponding
password.
Network security starts with authenticating, commonly with
a username and a password. Since this requires just one
detail authenticating the user name i.e. the password this is
sometimes termed one-factor authentication. With two-
factor authentication, something the user 'has' is also used
(e.g. a security token or 'dongle', an ATM card, or a mobile
phone); and with three-factor authentication, something the
user 'is' is also used. Once authenticated, a firewall enforces
access policies such as what services are allowed to be
accessed by the network users. Though effective to prevent
unauthorized access, this component may fail to check
potentially harmful content such as computer worms or
Trojans being transmitted over the network. Anti-virus
software or an intrusion prevention system (IPS. help detect
and inhibit the action of such malware. An anomaly-based
intrusion detection system may also monitor the network
like wireshark traffic and may be logged for audit purposes
and for later high-level analysis. Fingerprinting emerged as
a technological solution to avoid illegal content re-
distribution. Basically, fingerprinting consists of embedding
an imperceptible mark –fingerprint– in the distributed
content to identify the content buyer. The embedded mark is
different for each buyer, but the content must stay
perceptually identical for all buyers. Fingerprinting schemes
deter people from illegally redistributing digital data by
enabling the original merchant of the data to identify the
original buyer of a redistributed copy. Recently, asymmetric
fingerprinting schemes were introduced. Here, only the
buyer knows the fingerprinted copy after a sale, and if the
merchant finds this copy somewhere, he obtains a proof that
it was the copy of this particular buyer. In case of illegal re-
distribution, the embedded mark allows the identification of
the re-distributor by means of a traitor tracing system,
making it possible to take subsequent legal actions.
Although fingerprinting techniques have been available for
nearly two decades, the first few proposals in this field are
far from nowadays’ requirements such as scalability for
thousands or millions of potential buyers and the
preservation of buyers’ privacy.

Most fingerprinting systems can be classified in three
categories, namely symmetric, asymmetric and anonymous
schemes. In symmetric schemes, the merchant is the one
who embeds the fingerprint into the content and forwards
the result to the buyer; hence, the buyer cannot be formally
accused of illegal redistribution, since the merchant also had
access to the fingerprinted content and could be responsible
for the redistribution. In asymmetric fingerprinting, the
merchant does not have access to the fingerprinted copy, but
he can recover the fingerprint in case of illegal re-
distribution and thereby identify the offending buyer. In
anonymous fingerprinting, in addition to asymmetry, the
buyer preserves her anonymity (privacy) and hence she
cannot be linked to the purchase of a specific content, unless
she participates in an illegal re-distribution. Peer-to-peer
(P2P) computing or networking is a distributed application
architecture that partitions tasks or workloads between
peers. Peers are equally privileged, equipotent participants
in the application.
They are said to form a peer-to-peer network of nodes. Peers
make a portion of their resources, such as processing power,
disk storage or network bandwidth, directly available to
other network participants, without the need for central
coordination by servers or stable hosts. Peers are both
suppliers and consumers of resources, in contrast to the
traditional client-server model in which the consumption
and supply of resources is divided. Emerging collaborative
P2P systems are going beyond the era of peers doing similar
things while sharing resources, and are looking for diverse
peers that can bring in unique resources and capabilities to a
virtual community thereby empowering it to engage in
greater tasks beyond those that can be accomplished by
individual peers, yet that are beneficial to all the peers.
Many anonymous fingerprinting schemes exploit the
homomorphic property of public-key cryptography. These
schemes allow embedding the fingerprint in the encrypted
domain (with the public key of the buyer) in such a way that
only the buyer obtains the decrypted fingerprinted content
after using her private key. Other approaches for anonymous
fingerprinting do not exploit homomorphic encryption in
this way, but either 1) require highly demanding
technologies such as public-key encryption of the contents,
secure multiparty protocols, commitment protocols or zero-
knowledge proofs, among others, incurring prohibitive
computational and communicational costs; or 2) are based
on theoretical secure embedding algorithms for which no
proof of existence is available.
2. RELATED WORK
2.1 Rational Peer to Peer
The authors J.Domirgo-Ferror and D.Megias proposed
this “Distributed multicast of fingerprinted content based on
a rational peer-to Peer community”. In conventional
multicast transmission, one sender sends the same content to
a set of receivers. This precludes fingerprinting the copy
obtained by each receiver (in view of redistribution control
and other applications). A straightforward alternative is for
the sender to separately fingerprint and send in unicast one
copy of the content for each receiver. This approach is not
scalable and may implode the sender. We present a scalable
solution for distributed multicast of fingerprinted content, in
which receivers rationally co-operate in fingerprinting and
spreading the content. Furthermore, fingerprinting can be
anonymous, in order for honest receivers to stay
anonymous. This paper focuses on proposing a multicast
approach to the anonymous fingerprinting problem which
meets these two goals and shows a proof of concept with a
practical implementation of the proposed system. The idea is
to transfer the burden of a centralized fingerprinting
technology to a distributed network of buyers who will
collaborate to produce further copies of the fingerprinted
contents.
The solution guarantees the following properties:
Correctness: All protocols terminate successfully whenever
players are honest (no matter how other players behaved in
other protocols). Anonymity and unlinkability: Without
obtaining a particularDB, the merchant even when colluding
with the registration center– cannot identify a buyer
(anonymity). Furthermore, the merchant is not able to tell
whether two purchases were made by the same buyer
(unlinkability). Revocability and collusion resistance: Any
collusion of up tocbuyers aiming at producing a version b
D2Dfrom which none of them can be re-identified will fail:
frombDthe merchant will obtain enough information to
identify at least one collusion member. The content carries a
different anonymous fingerprint for each receiver, so that
unlawful content redistribution can be tracked ; honest
receivers stay anonymous. The sender does not need to
fingerprint and send the content individually to each
receiver; one fingerprinting and one unicast transmission by
the server to one collaborative receiver are enough to
bootstrap the process.
The advantages aided in this method are time domain
synchronization watermark is embedded for fast search of
information watermark position.A frequency-domain
information watermark is embedded next to the SYN
marks.Disadvantage of our proposed peer-peer multicast
protocol only deals with the redistribution control.
2.2 Spread Spectrum Fingerprinting in Asymmetric
Cryptographic Protocol
The author M.Kuribayashi Proposed this “On the
Implementation of Spread Spectrum Fingerprinting in
Asymmetric Cryptographic Protocol.Asymmetric Property
If both a buyer and a seller obtain a fingerprinted content in
a fingerprinting protocol, the seller cannot prove to a third
party about the illegal distribution by the buyer, even if the
buyer's fingerprint is extracted. This is because the seller
may distribute it himself in order to frame an innocent
buyer. Hence, it is desirable that only a buyer is able to
obtain his own fingerprinted content in the protocol. Such a
protocol is called asymmetric fingerprinting protocol. We
propose the method for implementing the spread spectrum
watermarking technique by carefully designing parameters
for rounding operation. If frequency components of digital

contents are used for the embedding fingerprint information,
they must be quantized in order to truncate real value to
integer. Then, the precision of the frequency components
should be considered in order not to degrade a watermarked
image. When the spread spectrum watermarking technique
in is applied, the precision of the representing watermark
signal is sensitive for the implementation. By scaling up the
parameters by multiplying a constant factor, the precision is
increased in our scheme. Then, the trade-off between the
scaling factor and the amount of data to be transmitted must
be considered. In addition, for the characteristic of the
fingerprinting protocol, frequency components and the
watermark signal must be separately encrypted after
quantization. In such a case, the consistency of the precision
is a sensitive issue. Since an embedding operation is
performed by addition of frequency components and a
spread spectrum sequence, the additive homomorphic
property of public-key cryptosystems can be directly
exploited for the embedding. Then, the separate rounding
operation causes interference term in a deciphered data at a
buyer side. Without loss of secrecy of an original content,
the interference term is removed after decryption. The
performance of our proposed method is evaluated
comparing with the conventional scheme, which conrms the
similar identification capability of illegal buyers. In a
fingerprinting scheme, each fingerprinted copy is slightly
different, hence, malicious users will collect some copies
with respective watermark in order to remove/alter the
watermark. Collusion-secure code which has traceability of
colluders.In the watermarking algorithm, it consists of
Embedding and Decryption and Post-Processing.
Advantages is the embedding operation can be easily
performed using the additive homomorphic property of
public-key cryptosystems such as the Okamoto-Uchiyama
encryption scheme. Disadvantages is we can simulate the
scheme on the cryptographic protocol with a limited
precision.
3. EXISTING SYSTEM
3.1 Security Model
The security assumptions of the systems are the following:
The merchant does not need to be trusted the either for
distribution or to associate a pseudonym with the identity of
the buyer. Buyers are not trusted and protocols are provided
to guarantee that 1. They are transferring authenticated
fragments of contents. 2. Their anonymity can be revoked
incase of illegal re-distribution.
The transaction monitor will not have access to the clear text
of the fingerprints. This prevents that any single party single
party can frame an innocent buyer.
The transaction monitor is trusted as the symmetric keys
used for encrypting the fragments. This means that the
Transaction monitor stores the key provided by each parent
buyer and this key can be retrieved only once from its
database.The transaction monitor returns the true
pseudonym corresponding to an illegal re-distributor in the
traitor tracing protocol. This trust can be replaced by a
collection of signatures provided by the proxies. The tracing
authority is a part of the legal system and shall be trusted the
communication between the merchant and the seed buyer
and between the peer buyers within the P2P distribution
system must be anonymous using an onion routing- like
approach. The fragments of content are encrypted using
symmetric cryptography. The proxies are not trusted and the
fragments sent through them shall be encrypted in such a
way that only the sender and the recipient have access to
their clear text.
The multimedia content is divided into several fragments
and each of the fragments is embedded separately with a
random binary sequence. The binary sequence of each
fragment is called segment and the concatenation of all
fragments forms the whole fingerprints. The merchant
distributes the different copies to the seed buyer and
fingerprints of this buyer. After that the buyer receives the
fragments from seed buyer. Then the communication
between the peer buyers is anonymous through onion
routing-like protocol using a proxy. Proxies know the
pseudonyms of source and destination buyers and they have
access to the symmetric keys used for encrypting the
multimedia content. Transaction record is created by
transaction monitor to keep track of each transfer between
peer buyers. These records do not contain the fingerprints,
but only an encrypted hash of them. The fingerprints’ hashes
are encrypted in such a way that the private key of at least
one parent is required for obtaining their clear text. The real
identities of buyers are known only by the merchant.
3.2 Peer to Peer Distribution Protocol
In the original distribution protocol the fingerprints were not
stored in the traitor tracing monitor in order to protect the
privacy of the buyer. Only the hash of the fingerprint was
stored for each buyer. The fingerprint’s hash was encrypted
and stored as many times as parents each buyer each buyer
had, using the public key of the parent for encryption. The
transaction registers would be formed as follows:
Pi --> Username of the buyer
H(c)-> Perceptual content hash
Ehi-> Encrypted hash of the buyer’s fingerprint.
Efi-> Encrypted buyer’s fingerprint.
d-> Transaction date and time.
the transaction monitor stores the following encrypted
version of the fingerprint:
Efi = E (E c
g1 |E c
g2 |….E c
gm ,Ka ) |…..| E (E c
g(L-1)m+2 | Ec
g(L-
1)m+2 |…|E c
gLm ,Ka ).
3.3 Algorithm Description
DES algorithm used in previous work. It uses 64 bit block
cipher and it encrypts 64 bit data at a time. DES uses the
two basic techniques of cryptography - confusion and
diffusion. At the simplest level, diffusion is achieved
through numerous permutations and confusions is achieved
through the XOR operation. The execution time is slow in
DES algorithm.

4. PROPOSED SYSTEM
To overcome the problems in the existing system, here we
include so many improved measures. In our proposed
system the components we are going to include are
Merchant, seed buyers, other buyers, proxies, tracing
authority and transaction monitor. The work of the merchant
is that he distributes copies of the content legally to the seed
buyers. Each fragment of the content contains a different
segment of the fingerprint embedded into it. The segments
have low pair-wise correlations. The work of seed buyers is
they receive fingerprinted copies of the contents from the
merchant that are used by the P2P distribution system to
bootstrap the system. The works of other buyers are they
purchase the content and obtain their fingerprinted copies
from the P2P distribution system. The content is assembled
from fragments obtained from different parents. Anonymous
connections with peer buyers are provided by means of
proxies. The duties of proxies are they provide anonymous
communication between peer buyers by means of a specific
protocol analogous to Chaum’s mix networks. The work of
tracing monitor is it keeps a transaction register for each
purchase carried out for each buyer. This transaction register
includes an encrypted version of the embedded fingerprints.
The work of tracing authority in case of illegal re-
distribution, it participates in the tracing protocol that is
used to identify the illegal re-distributor(s).The
watermarking method used for embedding and detecting the
fingerprint is transparent, robust and secures enough for a
fingerprinting application. Collusion occurs when several
buyers decide to recombine their fingerprinted copies of a
given content trying to obtain a new copy in which neither
of their fingerprints is detectable. Buyer frameproofness is
related to the possibility that an innocent buyer is accused of
illegal redistribution of the purchased content.
Advantages
Our proposed system improves the efficiency of the
fingerprinted system
It also preserves the privacy of the original copy of the
multimedia file
It effectively detects the traitors who are all misuse the
original copy of multimedia file.
It uses the recombined fingerprints for validation, so it
generates the effective result.

4.2.1 Data Distribution
In the data distribution process, it first identify the merchant
information. That is full details about the merchant,
merchant id, etc. After that merchant should select the
multimedia file which they going to send to the buyers. In
the process, the name of the multimedia file, type of the
multimedia file and extension of the multimedia file finally
size of the multimedia file are displayed. After that in a
client server process they transmit the merchant information
and the contents they are going to send to the buyers are
viewed. Finally the buyers who are all take part in this file
sharing process are viewed. Here we select the final
selection of buyer and merchant information.
4.2.2 Fingerprinted Copies to Seed Buyers
After the analyzing process, the copies are ready to send to
the buyers. Before the transmission process, we are going to
encrypt the copies. In this process we are going to convert
the multimedia file into number of copies of images. After
that view the information about the images we convert
during the first process. Finally we encrypt the images using
AES algorithm. Using the encryption algorithm we encrypt
the images which we converted during the conversion
process. Finally send the encrypted image copies to the seed
buyers.
4.2.3 Distribution to Other Buyers
The encrypted copies are first received to the seed buyers.
After the copies are received at the seed buyers, these copies
are ready to send to the other buyers. In the middle process,
the copies are converted into the binary values. This binary
value is mainly used for the validation process. These binary
values are the fingerprints of the copies of the video files.
There are separate fingerprint is generated for the each and
every copies send to the seed buyers, from the seed buyers
to the other buyers. Here we show the binary values of the
fingerprints of the copies of the multimedia files are viewed.
4.2.4 Transaction Monitoring
In the transaction monitoring it contains the record of each
and every transaction. That is the copy of the multimedia
file send from one peer to another peer, the ip of the sender
peer and receiver peer are recorded in the transaction
monitoring. This transaction monitoring is helpful to
identify the illegal distribution of multimedia file copies to
the peer involved in the network. It is like a register which
contains the information about all the peers and transactions
etc After that we show all the transaction information about
the peers takes part in the network.
4.2.5 Traitor Tracing Protocol
It is a final step, in this module it detects the tracing of the
illegal distributors. In case of illegal re-distribution, it
participates in the tracing protocol that is used to identify the

illegal re-distributor(s).By referring the transaction monitor,
it detect the illegal distribution of videos among the
merchant and the seed buyers.
4.3 Proposed Algorithm Description
Blowfish algorithm is a symmetric block cipher key. It is
used for encryption. It takes a variable-length key, from 32
bits to 448 bits. Blowfish is unpatented and license free
algorithm. Blowfish is a variable-length key block cipher. It
is suitable for applications where the key does not change
often, like a communications link or an automatic file
encrypted. It is significantly faster than most encryption
algorithms when implemented on 32-bit microprocessors
with large data caches. It manipulates data in large blocks. It
has a scalable key from 32 bits to at least 256 bits. It has no
linear structures that reduce complexity. Blowfish has 16
rounds. The input is a 64-bit data element, X. It divides X
into 32-bit halves: XL , XR
Then, for i=1 to 16:
XL= XL XOR Pi
XR = F(XL) XOR XR, Swap XL and XR

published system fail under some circumstances. Tracing
authority identify the illegal redistribution of data. And the
correct users can get the data without any interruption. If
any unwanted distribution is made the traitor tracing
protocol detects the illegal re-distribution of the content.
Future work in our project will change the algorithm
concept for execution process or change the protocol to
detect illegal transaction.
