Data de-duplication is one of the essential data compression techniques for eliminating duplicate copies of repeating data, and it has been widely used in cloud storage to reduce the amount of storage space and save bandwidth. To protect the privacy of sensitive data while supporting de-duplication, the salt encryption technique has been proposed to encrypt the data before its outsourcing. To protect the data security in a better way, this paper makes the first attempt to formally address the problem of authorized data de-duplication. Different from traditional de-duplication systems, the derivative privileges of users are further considered in duplicate check besides the data itself. We also present various new de-duplication constructions which supports the authorized duplicate check in hybrid cloud architecture. Security analysis demonstrates that the scheme which we used is secure in terms of the definitions specified in the proposed security model. We enhance our system in security. Specially, we present a forward-looking scheme to support a stronger security by encrypting file with differential privilege keys. We show that our proposed authorized duplicate check scheme incurs minimal overhead compared to normal operations.
Implementation of De-Duplication AlgorithmIRJET Journal
The document describes an implementation of a data de-duplication algorithm using convergent encryption. It discusses how data de-duplication works to reduce storage usage by identifying and removing duplicate copies of data. Convergent encryption is used, which generates the same encrypted form of a file from the original file's hash, allowing duplicate encrypted files to be de-duplicated while preserving privacy. The algorithm divides files into blocks, generates hashes for each block, and encrypts the file blocks using the hashes as keys. When a file is uploaded, its hash is checked against existing hashes to identify duplicates, with duplicates replaced by pointers to the stored copy. This allows efficient de-duplication while encrypting data for privacy and security when stored

Securely Data Forwarding and Maintaining Reliability of Data in Cloud ComputingIJERA Editor
Cloud works as an online storage servers and provides long term storage services over the internet. It is like a third party in whom we can store a data so they need data confidentiality, robustness and functionality. Encryption and encoding methods are used to solve such problems. After that divide proxy re-encryption scheme and integrating it with a decentralized erasure code such that a secure distributed storage system is formulated. The distributed storage system not only supports secure, robust data storage and retrieval but also lets the user forward his data to another user without retrieving the data. A concept of backup in same server allows users to retrieve failure data successfully in the storage server and also forward to another user without retrieving the data back. This is an attempt to provide light-weight approach which protects data access in distributed storage servers. User can implement all important concept i.e. Confidentiality for security, Robustness for healthy data, Reliability for flexible data, Availability for compulsory data will be achieved to another user which is store in cloud and easily overcome problem of “Securely data forwarding and maintaining, reliability of data in cloud computing “using different type of Methodology and Technology.
The document describes a secure cloud storage system that supports data forwarding without retrieving data. It uses a threshold proxy re-encryption scheme combined with a decentralized erasure code. This allows storage servers to directly re-encrypt and forward encrypted data to another user, without having the plaintext. The system has four phases: setup, storage, forwarding, and retrieval. It discusses parameters for the number of storage servers and key shares to provide security and robustness. The scheme supports encoding and forwarding of encrypted data in a distributed manner across independent servers.
IRJET - A Secure Access Policies based on Data Deduplication SystemIRJET Journal
This document summarizes a research paper on a secure access policies based data deduplication system. The system uses attribute-based encryption and a hybrid cloud model with a private cloud for deduplication and a public cloud for storage. It allows defining access policies for encrypted data files. When a user uploads a duplicate file, the system checks for a matching file and replaces it with a reference to the existing copy to save storage. The system provides file and block-level deduplication for efficient storage and uses cryptographic techniques like MD5, 3DES and RSA for encryption, tagging and access control of encrypted duplicate data across clouds.
This document proposes new distributed deduplication systems with improved reliability for cloud storage. It introduces distributing data chunks across multiple cloud servers to provide better fault tolerance compared to single-server systems. A secret sharing scheme is used to split files into fragments and distribute them across servers, instead of encryption, to achieve data confidentiality while still allowing for deduplication. Security analysis shows the proposed systems achieve confidentiality, integrity, and reliability even if some servers collude. The systems are implemented and shown to incur low overhead.

Resist Dictionary Attacks Using Password Based Protocols For Authenticated Ke...IJERA Editor
A parallel file system is a type of distributed file system that distributes file data across multiple servers and
provides for concurrent access by multiple tasks of a parallel application. In many to many communications or
multiple tasks, key establishments are a major problem in parallel file system. So we propose a variety of
authenticated key exchange protocols that are designed to address the above issue. In this paper, we also study
the password-based protocols for authenticated key exchange (AKE) to resist dictionary attacks. Password-based
protocols for authenticated key exchange (AKE) are designed to work to resist the use of passwords drawn from
a space so small that attacker might well specify, off line, all possible passwords. While many such protocols
have been suggested, the elemental theory has been lagging. We commence by interpreting a model for this
problem, to approach password guessing, forward secrecy, server compromise, and loss of session keys.

In available practically proven Data clustering practices for eradicating same copies of replicated data, Data de-replication is one of significant mechanisms, and has been extensively practiced in cloud storage to diminish the quantity of storage space and accumulate bandwidth. To guard the privacy of responsive data though sustaining de-replication, the convergent encryption technique has been anticipated to encrypt the data before redirecting. For an improvised shielding of data safety, this paper formulates the primary effort to formally speak to the problem of approved data de-replication. Diverse from conventional de-replication systems, the discrepancy privileges of users are auxiliary considered in replica verification besides the data itself. In this we introduce several novel de-replication structural methods in sustaining approved replica test in hybrid cloud architecture. Safety examination demonstrates that our system is protected in terms of the description particular in the anticipated security model. As an evidence of perception, we execute a model of our anticipated approved replica check method and perform test-bed research using our model. We demonstrate that our anticipated approved replica check method acquire minimal overhead evaluated to standard procedures.
This document summarizes various data encryption techniques for securing data in cloud computing. It discusses hybrid encryption algorithms that combine Caesar cipher, RSA, and monoalphabetic substitution. It also describes the DES algorithm and its structure. Finally, it explores identity-based encryption (IBE) where a third party generates public keys based on user identifiers like email addresses. The document concludes that data security is an important issue for cloud computing and more research is still needed to enhance security features using cryptographic techniques.
This document proposes new distributed deduplication systems with higher reliability for secure cloud storage. The key points are:
1. Existing deduplication systems improve storage efficiency but reduce reliability as files are only stored once in the cloud.
2. The proposed systems distribute file chunks across multiple cloud servers using secret sharing to improve reliability.
3. Security mechanisms like confidentiality and tag consistency are achieved through deterministic secret sharing rather than encryption.
IRJET- Multiple Keyword Search over Encrypted Cloud DataIRJET Journal
This document proposes a system for multi-keyword ranked search over encrypted cloud data. The system consists of four main components: data owners who upload encrypted data to the cloud server, data users who search for and access encrypted files, an administrator server that handles authentication and generates trapdoors for searches, and the cloud server that stores the encrypted data and indexes. When a data user performs a search, the administrator generates an encrypted trapdoor for the keywords to allow searching without revealing the plaintext to the cloud server. Search results are ranked based on factors like download frequency. The proposed system aims to provide secure, authenticated searches over outsourced encrypted data while preserving data privacy.

1. The document proposes new distributed deduplication systems that improve reliability by distributing data chunks across multiple cloud servers. This addresses limitations of single-server deduplication systems where losing one server causes disproportionate data loss.
2. The systems introduce a deterministic secret sharing scheme to protect data confidentiality in distributed storage, instead of using convergent encryption. Secret shares of files are distributed across servers.
3. The distributed approach enhances reliability while supporting deduplication and ensuring data integrity and "tag consistency" to prevent replacement attacks. This represents the first work addressing reliability, confidentiality and consistency for distributed deduplication.
IRJET- Distributed Decentralized Data Storage using IPFSIRJET Journal
This document describes a distributed decentralized data storage system that uses the Interplanetary File System (IPFS) protocol. The system allows users to encrypt files locally before uploading them, where they are broken into pieces and stored across multiple devices on the network with 51% redundancy to prevent data loss. Hashes are used to track the pieces and access the files. The system aims to provide privacy, security, and reliability through decentralization without a single point of failure. Files are encrypted, distributed, and accessed through a peer-to-peer network where each participating node contributes storage and acts as both a server and storage provider.
This document proposes a self-assured deduplication system for authorized deduplication in a hybrid cloud. The system uses convergent encryption to encrypt data before uploading it to the public cloud while allowing for deduplication. A private cloud server manages the private keys and generates file tokens to allow authorized duplicate checking on the public cloud. The proposed system was implemented as a prototype and experiments show it incurs minimal overhead compared to normal operations like encryption and uploading.
Enabling Integrity for the Compressed Files in Cloud ServerIOSR Journals
This document proposes a scheme for enabling data integrity for compressed files stored in cloud servers. The scheme encrypts some bits of data from each data block using an RSA algorithm and polynomial hashing to generate hash values. These hash values are stored at the client and used to verify integrity by checking responses from the cloud server against the stored hashes. The scheme aims to minimize computational and storage overhead for clients by compressing files, encrypting only some data bits, and requiring clients to store just two secret functions rather than the full data. This allows integrity checks with low bandwidth consumption suitable for thin clients like mobile devices.
The document describes a proposed secure distributed storage system that integrates a threshold proxy re-encryption scheme with a decentralized erasure code. This allows for secure and robust storage and retrieval of data in the cloud while also enabling a user to securely forward data to another user without retrieving it first. The system fully integrates encryption, encoding, and secure data forwarding capabilities. It is intended for applications where secret data transmission is required, such as in military or hospital settings.
IRJET - Privacy Preserving Keyword Search over Encrypted Data in the CloudIRJET Journal
The document discusses privacy preserving keyword search over encrypted data in the cloud. It proposes a personalized search (PSU) scheme that uses natural language processing on the client side to pre-compute search results for user queries before uploading encrypted data to the cloud. This allows encrypted keyword searches to be performed efficiently without retrieving all encrypted data from the cloud.
An Auditing Protocol for Protected Data Storage in Cloud Computingijceronline
Cloud computing is a mechanism which provides us resources, information as per user requirement by the help of internet. Cloud is used to store important content material for a longer period of time which requires trust and safety of content that is stored in cloud. The main issue of cloud computing is security of data. Many techniques proposed earlier were beneficial for static archived data. Some encryption techniques were introduced later for dynamic data which includes masking technique, bilinear property with dynamic auditing. This paper proposed an effective auditing protocol to maintain the dynamic operations on data with RSA, MD5 and ID3 algorithms for enhancing data safety. The analysis and simulation results are effectual and protected as it incurs least communication cost and least computation cost of the auditor.
This document defines and compares high culture and popular culture. High culture refers to cultural aspects that are most valued by the elite members of society, such as intellectuals. Popular culture refers to cultural practices embraced by the majority classes. Examples of high culture include opera, yachting, and fine novels. Popular culture examples include movies, billboard music charts, and top novels. The document then discusses examples of high culture and popular culture in Malaysia and the United States. High culture in Malaysia includes western restaurants, luxury goods, and high social status careers, while popular culture consists of local hawker foods, affordable transportation, and widespread sports.
This document discusses different readings of a magazine cover featuring Jake Bugg. The dominant reading is that the magazine aims to go against mainstream conventions, as shown by its tagline labeling Bugg an "enemy" of the popular TV show The X Factor. However, an oppositional reading suggests the magazine still somewhat conforms to mainstream ideas by portraying disliking The X Factor as something people should do. A third reading notes the cover subverts ideas of cultural hegemony by depicting Bugg in a relaxed, unmasculine pose at a bar.

This document proposes a self-assured deduplication system for authorized deduplication in a hybrid cloud. The system uses convergent encryption to encrypt data before uploading it to the public cloud while allowing for deduplication. A private cloud server manages the private keys and generates file tokens to allow authorized duplicate checking on the public cloud. The proposed system was implemented as a prototype and experiments show it incurs minimal overhead compared to normal operations like encryption and uploading.
Enabling Integrity for the Compressed Files in Cloud ServerIOSR Journals
This document proposes a scheme for enabling data integrity for compressed files stored in cloud servers. The scheme encrypts some bits of data from each data block using an RSA algorithm and polynomial hashing to generate hash values. These hash values are stored at the client and used to verify integrity by checking responses from the cloud server against the stored hashes. The scheme aims to minimize computational and storage overhead for clients by compressing files, encrypting only some data bits, and requiring clients to store just two secret functions rather than the full data. This allows integrity checks with low bandwidth consumption suitable for thin clients like mobile devices.
The document describes a proposed secure distributed storage system that integrates a threshold proxy re-encryption scheme with a decentralized erasure code. This allows for secure and robust storage and retrieval of data in the cloud while also enabling a user to securely forward data to another user without retrieving it first. The system fully integrates encryption, encoding, and secure data forwarding capabilities. It is intended for applications where secret data transmission is required, such as in military or hospital settings.
IRJET - Privacy Preserving Keyword Search over Encrypted Data in the CloudIRJET Journal
The document discusses privacy preserving keyword search over encrypted data in the cloud. It proposes a personalized search (PSU) scheme that uses natural language processing on the client side to pre-compute search results for user queries before uploading encrypted data to the cloud. This allows encrypted keyword searches to be performed efficiently without retrieving all encrypted data from the cloud.
An Auditing Protocol for Protected Data Storage in Cloud Computingijceronline
Cloud computing is a mechanism which provides us resources, information as per user requirement by the help of internet. Cloud is used to store important content material for a longer period of time which requires trust and safety of content that is stored in cloud. The main issue of cloud computing is security of data. Many techniques proposed earlier were beneficial for static archived data. Some encryption techniques were introduced later for dynamic data which includes masking technique, bilinear property with dynamic auditing. This paper proposed an effective auditing protocol to maintain the dynamic operations on data with RSA, MD5 and ID3 algorithms for enhancing data safety. The analysis and simulation results are effectual and protected as it incurs least communication cost and least computation cost of the auditor.

This document discusses different readings of a magazine cover featuring Jake Bugg. The dominant reading is that the magazine aims to go against mainstream conventions, as shown by its tagline labeling Bugg an "enemy" of the popular TV show The X Factor. However, an oppositional reading suggests the magazine still somewhat conforms to mainstream ideas by portraying disliking The X Factor as something people should do. A third reading notes the cover subverts ideas of cultural hegemony by depicting Bugg in a relaxed, unmasculine pose at a bar.

Meditation and yoga are ancient disciplines that lead to states of serenity, clarity, and bliss. Meditation involves witnessing one's thoughts and desires without judgment. In a deep meditative state, the mind experiences silence like an endless sky, connecting one to their senses and life. True meditation is a basic transformation that cannot be taught but must come from within through expanding one's consciousness. Yoga originated over 5,000 years ago and involves controlling the mind and body through poses, breathing techniques, and meditation to achieve spiritual enlightenment.

A Secure Multi-Owner Data Sharing Scheme for Dynamic Group in Public Cloud. IJCERT JOURNAL
In cloud computing outsourcing group resource among cloud users is a major challenge, so cloud computing provides a low-cost and well-organized solution. Due to frequent change of membership, sharing data in a multi-owner manner to an untrusted cloud is still its challenging issue. In this paper we proposed a secure multi-owner data sharing scheme for dynamic group in public cloud. By providing AES encryption with convergent key while uploading the data, any cloud user can securely share data with others. Meanwhile, the storage overhead and encryption computation cost of the scheme are independent with the number of revoked users. In addition, I analyze the security of this scheme with rigorous proofs. One-Time Password is one of the easiest and most popular forms of authentication that can be used for securing access to accounts. One-Time Passwords are often referred to as secure and stronger forms of authentication in multi-owner manner. Extensive security and performance analysis shows that our proposed scheme is highly efficient and satisfies the security requirements for public cloud based secure group sharing.
Methodology for Optimizing Storage on Cloud Using Authorized De-Duplication –...IRJET Journal
This document summarizes a research paper that proposes a methodology for optimizing storage on the cloud using authorized de-duplication. It discusses how de-duplication works to eliminate duplicate data and optimize storage. The key steps are chunking files into blocks, applying secure hash algorithms like SHA-512 to generate unique hashes for each block, and comparing hashes to reference duplicate blocks instead of storing multiple copies. It also discusses using cryptographic techniques like ciphertext-policy attribute-based encryption for authentication and security on public clouds. The proposed approach aims to optimize storage while providing authorized de-duplication functionality.

Messages addressed to specific users can be decrypted by Key Generation Centre (KGC) by generating their private keys. Data owner wants the data to be delivered only to specified user and not to unauthorized person that is the data owner makes their private data accessible only to authorized person. We propose attribute based encryption and escrow problem which means written agreement delivered to a third party to overcome this problem. Attribute based Encryption (ABE) is a type of public-key encryption in which the private key of a user and the cipher text are dependent upon attributes. It is a promising cryptographic approach.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Abstract— Data de-duplication is one of the essential data
compression techniques for eliminating duplicate copies of
repeating data, and it has been widely used in cloud storage
to reduce the amount of storage space and save bandwidth.
To protect the privacy of sensitive data while supporting de-
duplication, the salt encryption technique has been
proposed to encrypt the data before its outsourcing. To
protect the data security in a better way, this paper makes
the first attempt to formally address the problem of
authorized data de-duplication. Different from traditional
de-duplication systems, the derivative privileges of users
are further considered in duplicate check besides the data
itself. We also present various new de-duplication
constructions which supports the authorized duplicate check
in hybrid cloud architecture. Security analysis demonstrates
that the scheme which we used is secure in terms of the
definitions specified in the proposed security model. We
enhance our system in security. Specially, we present a
forward-looking scheme to support a stronger security by
encrypting file with differential privilege keys. We show that
our proposed authorized duplicate check scheme incurs
minimal overhead compared to normal operations.

I. INTRODUCTION
In this paper, we instant a scheme that permits a more fine-
grained trade-off. The motive behind this is that outsourced
data may require various levels of protection, depending on
how popular it is: content shared by many users, such as a
famous song or video, arguably requires less protection than
a personal document, the copy of a pay-slip or the draft of
an un-submitted scientific paper. As more corporate and
private users outsource their data to cloud storage providers,
recent data breach incidents make end-to-end encryption an
increasingly prominent requirement. Regrettably,
semantically secure encryption schemes provide various
cost-effective storage optimization techniques, such as data
de-duplication, ineffective. We present a novel and best idea
that differentiates data according to their popularity.
Depending upon this idea, we design an encryption scheme
which guarantees semantic security for unpopular data and
provides weaker and less security and better storage and
bandwidth benefits for popular data. Using this method,
data de-duplication can be effective for popular data, while
semantically secure encryption protects unpopular content.
Although data de-duplication brings a large number of
benefits, security and privacy concerns arise as users’
sensitive data is susceptible to both attacks i.e. insider as
well as outsider attacks. Traditional encryption technique,
while providing data confidentiality, is not compatible with
data de-duplication. Specifically, traditional encryption
needs various users to encrypt their data with their own
keys. Thus, identical or similar data copies of various users
will lead to different cipher a text which makes de-
duplication impossible. Salt encryption has been proposed
to enforce data confidentiality while making de-duplication
feasible. It encrypts/decrypts a data copy with a salt key,
which is obtained by computing the cryptographic hash
value of the content of the data copy. After the generation of
key and data encryption, users retain the keys and send the
cipher text to the cloud. Since the encryption operation is
deterministic and it is derived from the data content,
identical data copies will generate the same salt key and
hence the same cipher text. To prevent or protect from an

unauthorized access, a secure proof of ownership protocol is
also needed to provide the proof that the user owns the same
file when a duplicate is found. After the proof, subsequent
users with the same file will be provided with a pointer from
the server without needing to upload the same file. A user
will be able to download encrypted file with the pointer
from the server, which can only be decrypted by the
corresponding data owners with their salt keys. Thus, salt
encryption allows the cloud to perform de-duplication on
the cipher texts and the proof of ownership prevents the
unauthorized user to access
Each file uploaded to the cloud is also bounded by a set of
privileges to specify which type of users is allowed to
perform the duplicate check and access the files. Before
submitting the duplicate check request of some file, user
needs to take this file and his own privileges as inputs. The
user, thus able to identify a duplicate for this file only if
there is a copy of this file and a matched privilege stored in
cloud. For example, in an organisation, many different
privileges will be assigned to employees. In order to save
cost and efficient management, the data will be moved to
the storage server provider (S- CSP) in the public cloud
with specified privileges and the de-duplication method will
be applied to store only one copy of the similar or same file.
Because of privacy consideration, few files will be
encrypted and allowed the duplicate check by employees
with specified privileges to realize the access control.
Traditional de-duplication systems that are based on salt
encryption, although they provide confidentiality to some
extent, does not support the duplicate check with differential
privileges. In other words, no differential privileges have
been considered in the salt encryption technique of de-
duplication. It seems contradictory if we want to realize de-
duplications and differential authorization duplicate check at
the same time.
In this paper, we enhance our system in security.
Specifically, we present a forward-looking scheme to
support stronger and higher security by encrypting the file
with differential privilege keys. Using this way, the users
without corresponding privileges can’t perform the
duplicate check. Moreover, such un-authorized users cannot
decrypt the ciphertext even collude with the S-CSP. Security
analysis indicates that our system is highly secure in terms
of the definitions specified in the proposed security model.
A. SYSTEM MODEL
At a high level, our setting of interest is an enterprise
network, which consists of a group of affiliated clients
(example, employees of an organization) who will use the S-
CSP and store data with de-duplication technique. De-
duplication can be used frequently in these settings for data
backup and disaster recovery applications while greatly
reducing the storage space. Such systems are broad and are
more suitable to user file backup and synchronization
applications than richer storage abstractions. Three entities
are defined in our system, i.e. users, private cloud and S-CSP
in public cloud which is shown in Fig. 1. The S-CSP
performs the de-duplication by checking whether the
contents of two files are same and stores only one of them.
Fig. 1: Architecture of Authorized De-duplication
The access right to a file is defined based on a set of
privileges. The true definition of a privilege varies across
applications. Each privilege is represented in the form of a
short message called token. Every file is associated with
some file tokens, which denote the tag with specified
privileges. The user finds out and sends duplicate check
tokens to the public cloud for authorized duplicate check.
Users has access to the private cloud server, a semi- trusted
third party which will aid in performing deduplicable
encryption by creating file tokens for the requesting users.
We will further explain the role of the private cloud server
below. Users are also provisioned with per-user encryption
keys and credentials (example. user certificates). In this
paper, we will consider the file- level de-duplication only for
the simplicity. In another word, we refer a data copy to be a
whole file and file-level de-duplication which removes the
storage of any redundant files. Actually, block-level de-
duplication can be easily figure out from file-level de-
duplication. Specifically, to upload a file, a user generally
performs the file-level duplicate check first. If the file is a
duplicate, then all its blocks must be duplicates as well, else
ways, the user further start performing the block-level
duplicate check and finally identifies the unique blocks to be
uploaded. Each data copy (a block or a file) is associated
with a token for the duplicate check.
Notice that this is a novel architecture for data de-duplication
in cloud computing, which contain a twin clouds (the public
cloud and the private cloud). Actually, this hybrid cloud
setting recently has attracted more and more attention. For
example, an enterprise might use a public cloud scheme,
such as Amazon S3, for archived data, but continue to
maintain in-house storage for operational customer data.
Alternatively, the trusted private cloud could be a cluster of

as a service by a third party and provides the hardware based
security features to implement a remote execution
environment trusted by the users.
B. PROPOSED SYSTEM
Cloud computing is the use of computing resources (i.e.
hardware and the software) which are delivered as a service
over the network (usually the Internet). The name coming
from the common use of a cloud-shaped symbol as an
abstraction for the complex infrastructure it contains in
system diagrams. Cloud computing give authority to remote
services with a user's data, software and computation. Cloud
computing consisting of a hardware and a software
resources made accessible on the Internet as managed third-
party services. These services typically provide access to
advanced software applications and high-end networks of
server computers.
We propose advanced de-duplication system which supports
authorized duplicate check. In this new system of de-
duplication, hybrid cloud architecture has been introduced
to solve the issue. The private keys for privileges will not be
issued to the users directly, which will be kept and managed
by the private cloud server instead. In this way, the users
cannot share these private keys of privileges in this
proposed construction, which means that it can prevent the
privilege key sharing among the users in the above
straightforward construction. To get a token of the file, the
user needs to send a request to the private cloud server. The
intuition of this construction can be described as follows. To
perform the duplicate check for some file, the user needs to
acquire the file token from the private cloud server. The
private cloud server will also check the identity of the user
before providing the corresponding file token to the
specified user. The authorized duplicate check for this file
can be carried out by the user with the public cloud before
uploading this file. Now on the basis of the results obtained
from duplicate check, the user either upload this file or runs
PoW. How successful an adversary is at breaking a system
is measured by its advantage. An adversary's advantage is
the difference between the adversary's probability of
breaking the system and the probability of the system can be
broken by simply guessing. The advantage is specified as the
function of the security parameters.
For everyone all the files are sensitive and it needs to be
protected fully against both public cloud and private cloud.
Under the assumption, two types of adversaries are
considered, i.e. 1) external adversaries which aims to extract
secret or private information as much as possible from both
public cloud and private cloud. and 2) internal adversaries
which aims to obtain more information on the file from the
public cloud and duplicate-check token information from
the private cloud outside their scopes. Such adversaries may
contain S-CSP, private cloud server and authorized users.
The detailed and full security definitions against these
adversaries is discussed in the below and in Section 5,
where the attacks are launched by external adversaries can
be viewed as special attacks from internal adversaries.
II. LITERATURE SURVEY
In archival storage systems, there is a enormous amount of
duplicate data or redundant data, which occupy prominent
extra equipments and power consumptions. The goal of data
de-duplication is to minimize the duplicate data in the inter
level, has been receiving broad attention both in academic
and industry in recent years. With the advent of cloud
computing, secure data de-duplication has attracted more
attention from research community.
Yuan et al.[1] introduced a de-duplication system in cloud
storage to reduce the storage size of tags for integrity check.
To increase the security of de-duplication and protect the
confidentiality,
Bellare et al.[2] demonstrate how to protect the data
confidentiality by transforming the predictable message into
unpredictable message. In their system, another third party
called key server is proposed to generate the file tag for
duplicate check.
Stanek et al. presented a novel encryption scheme that
endows the essential security for popular data as well as
unpopular data. For popular data that are not particularly
sensitive, the traditional conventional encryption is
performed. Another two-layered encryption scheme with
stronger security while supporting de-duplication is
introduced for unpopular data. In this way, they achieved
preferable trade between the efficiency and security of the
outsourced data. Liet al. addressed the key management
issue in block level de-duplication by distributing these keys
across multiple servers after encrypting the files.
III. SECURE SYSTEM
A.Symmetric encryption
Symmetric encryption algorithm uses a most common secret
key K to encrypt and decrypt the information. A symmetric
encryption scheme consists of mainly three primitive
functions:
• KeyGenSE (1λ ) → K is the key generation algorithm
which generates K using security parameter 1λ;
• EncSE (K, M ) → C is the symmetric encryption
algorithm that takes the secret K and message M and then
gives the output ciphertext C; and
• DecSE (K, C ) → M is the symmetric decryption
algorithm that takes the secret K and cipher-text C and
thenprovide the output as the original message M.
B.Salt Encryption Technique
A new salt is arbitrarily generated for each data. In a typical
setting, the salt and the data are united and processed along
with a cryptographic function, and the resulting i.e. final

output (not the original data) is stored with the salt in a
database. Hashing will be allowed for later authentication
while protecting the plain text data in the event that the
authentication data store is compromised.
To support authorized de-duplication, the tag of a file F will
be determined by the file F and the privilege. To display the
difference with traditional notation of tag, we call it file
token instead. To support the authorized i.e legal access, a
secret key kp will be bounded with a privilege p in order to
generate a file token. Let φ′F, p = TagGen(F, kp) denotes the
token of F which is allowed to access by user with privilege
p. In other word, the token φ′F, p could only be computed by
the users with privilege p. As a result, if a file has been
uploaded by a user having a duplicate token φ′F,p then a
duplicate check which has been sent from other user will be
successful only if he also having the file F and a privilege p.
Such a token generation function can be easily implemented
as H(F,kp), where H(·) indicates a cryptographic hash
function.
Our system is designed to solve the differential privilege
problem in the secure de-duplication process. The security
will be examined in terms of two aspects, i.e. first one is the
authorization of duplicate check and second one is the
confidentiality of data. Some basic tools have been used to
construct the secure de-duplication, which are assumed to be
highly secure. These basic tools consist of the salt
encryption scheme, symmetric encryption scheme, and the
PoW scheme. Based upon this assumption, we show you
that our systems are secure with respect to the following
security analysis.
Before giving our construction of the de-duplication system,
we define a binary relation R = {((p, p′ )} as follows. We
have two privileges let’s say them p and p′, we can say that p
matches p′ only if R (p, p′) = 1. This type of a generic binary
relational definition could be instantiated based on the
background of the applications, such as the common
hierarchical relation. More accurately, In a hierarchical
relation, p matches p′ if and only if p is a higher-level
privilege.
A symmetric key kpi for each and every pi ∈ P will be
selected and the set of keys {kpi }pi ∈P will be sent to the
private cloud. An identification protocol Π = (Proof, Verify)
is also going to defined, where Proof and Verify are the
proof and verification algorithm respectively. Moreover,
each user i.e. U has a secret key skU to perform the process
of identification with servers. Let us assume that user U has
the privilege set PU. It also initializes a PoW protocol POW
for the file ownership proof. The private cloud server will
maintain a table which can store each and every user’s public
information pkU and its corresponding privilege set PU.
Suppose that a data owner wanted to upload and share a file,
let’s say, F with users whose privilege belongs to the set PF =
{pj }. The data owner needs to interact with the private cloud
before performing the process of duplicate check with the S-
CSP. More accurately, the data owner performs an
identification process in order to prove its identity with
private key skU. If it is passed, the private cloud server will
find the corresponding privileges PU of the user from its
stored table list. The user then computes and immediately
sends the file tag φF = TagGen(F) to the private cloud server,
who will return {φ′F,pτ = TagGen(φF , kpτ )} back to the user
for all pτ satisfying R(p,pτ) = 1 and p ∈ PU. Then, the user
will interact and sends the file token {φ′F,pτ } to the S-CSP.
That is, the user can finally recover the original file with the
convergent key kF after receiving the encrypted data from the
S-CSP.
The encryption key can be viewed as the form of
kF,p = H’(H(F),kp)H2(F)
Where H’, H and H2 are all the cryptographic hash
functions. The file F is encrypted with another key k, while k
will be encrypted with kF, p. In this way, the private cloud
server and S-CSP cannot decrypt the ciphertext.
Furthermore, it is semantically secure to the S-CSP based on
the security of symmetric encryption.
IV. EXPERIMENTALRESULT
There are some experimental results given below. Fig. 2.

graph of different files uploaded by the user. Here we just
took a random set of files and uploaded it and just saw the
results for each step i.e. token generation, duplicate check,
encryption, transfer.

And if no duplicate is found then the file will be stored in
the cloud server.
V. CONCLUSION
In this paper, the impression of authorized data de-
duplication was proposed to protect the data security by
including differential privileges of users in the duplicate
check. Safety analysis demonstrates that our technique is
more secure in terms of both the attacks i.e. insider as well
as outsider attacks specified in the proposed security model.
We also presented several new de-duplication constructions
supporting accredited duplicate check in hybrid cloud
architecture, in which the duplicate-check tokens of files are
generated by the private cloud server with private keys. As a
proof of concept, we enforced a prototype of our proposed
authorized duplicate check scheme and conduct testbed
experiments on our prototype.
