Due to the increasing popularity of video services application in recent days, it is
undesirable to prevent the content leakage on the trusted video delivery and piracy prevention has
been indeed, become critical. In order to preserve content leakage and prevent piracy,
conventional system addressed the issue by proposing the method based on the observation of
streamed traffic throughout the network .Also piracy has hindered the use of open peer to peer
networks for commercial content delivery. Hence the basic idea is to propose an enhanced
dynamic content leakage detection scheme that is robust to the variation of the video lengths. It
enhances the detection performances even in the environment subjected to variation in length of
videos. To detect pirates, identity-based signature and time stamped token have been generated. It
helps to solve piracy without affecting P2P clients so that colluder cannot download the secured
videos. The advantage lies mainly in advanced content availability, low cost and copyright
agreements in protecting the secured videos.
This document discusses video conferencing security and provides guidelines for selecting the appropriate security level for organizations. It recommends that mainstream applications can securely use video over the open internet with 128-bit AES encryption, as this level of encryption is trusted by major financial institutions for online transactions. For some organizations that require higher security or quality of service, a dedicated private network combined with encryption may be preferable. The highest security level involves custom government and military solutions that utilize classified encryption algorithms and hardware. Overall, the document advocates that encryption can ensure secure video communications without compromising quality or performance when combined with proper firewall configuration.
Dr. Arun Sood is a professor of computer science who has developed an approach called Self Cleansing Intrusion Tolerance (SCIT) to improve server security. SCIT works by converting static servers into dynamic servers that refresh regularly, reducing exposure time to malware while maintaining service. His research aims to limit losses from successful attacks by restoring servers to a pristine state frequently. SCIT has been implemented to refresh servers every minute, limiting the time for malware to cause damage.

Digital Watermarking Applications and Techniques: A Brief ReviewEditor IJCATR
Digital watermarking is a technique used to embed hidden identification information into digital media such as images, audio and video. This allows for copyright protection, proof of ownership and transaction tracking. There are two main domains watermarks can be embedded in - the spatial domain directly modifies pixel values, while the transform domain modifies frequency coefficients. Common transform domain techniques are DCT, DWT and DFT which provide better robustness against attacks. The paper reviews various watermarking applications such as broadcast monitoring, ownership assertion and content authentication, as well as spatial and transform domain techniques including LSB, DCT and DWT.

Wireless Vulnerability Management: What It Means for Your EnterpriseAirTight Networks
The instant and obvious benefits of WiFi have made WLANs a big success
in public, private, and enterprise sectors. Unfortunately, the adoption of
correct security measures for WLANs is lagging far behind the fast pace
at which these networks are being deployed. The presence of WiFi in
most laptops and handhelds, the simplicity of independently installing
WiFi networks, and the ease of exploiting wireless vulnerabilities have
together escalated the risks manifold. Even organizations that do not
own a WLAN are equally at risk.
The document discusses the Cisco Catalyst 6500 and Firewall Services Module (FWSM). It notes the importance of data center security and protecting servers from attacks. The Cisco Catalyst 6500 delivers security through features like network admission control, identity-based networking, and intrusion prevention. It can consolidate security functions to reduce power consumption. The FWSM integrates firewall capabilities into the Cisco Catalyst 6500 and 7600 series switches in a high-performance module.
SCIT-MTD is a patented technique that provides continuous rotation of virtual machines to a pristine state in order to remove malware and limit the time intruders have to exploit systems. It uses virtualization and fast VM rotation times of less than a minute to dynamically change systems into moving targets. This makes it difficult for attackers to gain access and plan attacks before being removed from the system. SCIT-MTD can be implemented without changes to existing systems and improves security even without knowing the details of vulnerabilities or malware.
Development of a Multi-eID access control system. ePractice.eu
The document discusses how the city of Grosseto developed an open source multi-eID access control system called Open Portal Guard to provide secure online access to citizens using various electronic IDs (eIDs). They rejected a proprietary solution proposed due to licensing fees, platform restrictions, and other issues. Facing resource constraints but wanting high quality and interoperability, they took an open source approach, engaging the international community to amplify their knowledge and develop a standards-based, technology neutral system supporting multiple eIDs. The system has been successfully used and they hope to encourage other organizations to adopt open source and collaborative development approaches.
The variety and complexity of cyber attacks is increasing. The attackers have a strong economic and political motivation thus leading to organized and targeted attacks. We have concluded that intrusions are inevitable, and have focused on strategies to work through the attack while limiting the losses. Our approach, called Self Cleansing Intrusion Tolerance (SCIT), leads to the next generation of secure servers. SCIT shifts the focus from intrusion avoidance to reducing the losses resulting from an intrusion. This additional layer of defense is justified, because the current reactive approaches cannot keep up with the rapidly increasing new threats.

SECURITY IMPLEMENTATION IN MEDIA STREAMING APPLICATIONS USING OPEN NETWORK AD...Journal For Research
Media has been a very important medium for entertainment and communications and the captured media was transmitted in analog form. Media providers do not want their end users to store and duplicate the streamed media because the end user can freely distribute the streamed media without any control from the source. Hence while dealing with media streaming, replay protection and integrity protection are the most important factors. The main aim of this paper is to implement the concept of WebRTC to stream the media between the participating end points which is a powerful tool used to incorporate RTC capabilities into browsers and mobile applications. The aim is to develop a secure media stream from an end point that flows through the Open Network Adapter to the Avaya Media Server (AMS) and is hosted by an application on the Engagement Development Platform. The Open Network Adapter with Avaya Fabric Attach is capable of securing the required flow.
This document outlines the requirements specification for a research project on video watermarking. The main aims of the project are to address copyright protection of digital video and develop a video watermarking scheme based on the Discrete Wavelet Transform using Matlab Simulink. The goals are to embed a watermark imperceptibly into video while making it robust against various attacks. The justification is that video faces increased attacks compared to other media. The work schedule outlines tasks from February to June 2015 including research, planning, analysis, design, coding and testing.
This document summarizes a research paper on embedding digital signatures in video for security purposes. It discusses how digital watermarking can be used to authenticate digital video content by inserting copyright information. The paper proposes a method that uses discrete wavelet transform to embed different parts of a watermark image into different video scenes. It describes the watermark embedding process, which involves extracting video frames, applying DWT, dividing the watermark into parts, and embedding parts into DWT coefficients. Experimental results show the watermarked frames are visually similar to originals and maintain adequate quality metrics. The method aims to provide robust video authentication against various attacks.

Real Time Head Generation for Video ConferencingIRJET Journal
This document proposes a real-time video synthesis model for video conferencing that reconstructs video at the receiver end to maintain a steady experience. It extracts and retargets motion from sender video frame by frame and synthesizes video on the receiver end using the first image and motion keypoints. This allows it to transfer facial expressions, head poses, and eye movements between videos using less bandwidth than standard H.264 video. The model uses WebRTC for peer-to-peer connections and a first-order motion model to extract and apply motion from one video to another in real-time for live video conferencing.
Video transmission over wireless networks is considered the most interesting application in our daily life nowadays. As
mobile data rates continue to increase and more people rely on wireless transmission, the amount of video transmitted over at least one
wireless hop will likely continue to increase. This kind of application needs large bandwidth, efficient routing protocols, and content
delivery methods to provide smooth video playback to the receivers. Current generation wireless networks are likely to operate on
internet technology combined with various access technologies. Achieving effective bandwidth aggregation in wireless environments
raises several challenges related to deployment, link heterogeneity, Network congestion, network fluctuation, and energy consumption.
In this work, an overview of technical challenges of over wireless networks is presented. A survey of wireless networks in recent video
transmission schemes is introduced. Demonstration results of few scenarios are showed.
A high-resolution video surveillance management system incurs huge amounts of storage and network bandwidth. The current infrastructure required to support a high-resolution video surveillance management system (VMS) is expensive and time consuming to plan, implement and maintain. With the recent advances in cloud technologies, opportunity for the utilization of virtualization and the opportunity for distributed computing techniques of cloud storage have been pursued on the basis to find out if the various cloud computing services that are available can support the current requirements to a highresolution video surveillance management system. The research concludes, after investigating and comparing various Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) cloud computing provides what is possible to architect a VMS using cloud technologies; however, it is more expensive and it will require additional reviews for legal implications, as well as emerging threats and countermeasures associated with using cloud technologies for a video surveillance management system..
IRJET- Privacy Preserving and Proficient Identity Search Techniques for C...IRJET Journal
This document presents a privacy preserving and efficient identity search technique for cloud data security. It proposes a scheme using visual-encryption techniques to overcome issues with untrusted cloud storage. The existing methodology uses data signing algorithms but has limitations as the private key depends on the security of one computer. The proposed system uses visual-cryptographic encryption, which scrambles data using an algorithm requiring a key to decrypt. It involves users uploading encrypted files, administrators approving requests to view files through live video verification, and decryption using the appropriate key. The scheme aims to securely store large volumes of data while allowing identity verification for file access on the cloud.

This document provides an overview of a minor project being conducted by computer science students at Ujjain Engineering College on real-time communication using WebRTC. It introduces WebRTC and discusses how it allows peer-to-peer media exchange between devices by establishing connections through a signaling process. The project aims to provide high-quality video/audio calls with less connection time and better security using encryption techniques. It outlines the topics that will be covered, including signaling, expected outcomes like low latency and platform independence, and the software requirements.
The ubiquitous and connected nature of camera loaded mobile devices has greatly estimated the value and importance of visual information they capture. Today, sending videos from camera phones uploaded by unknown users is relevant on news networks, and banking customers expect to be able to deposit checks using mobile devices. In this paper we represent Movee, a system that addresses the fundamental question of whether the visual stream exchange by a user has been captured live on a mobile device, and has not been tampered with by an adversary. Movee leverages the mobile device motion sensors and the inherent user movements during the shooting of the video. Movee exploits the observation that the movement of the scene recorded on the video stream should be related to the movement of the device simultaneously captured by the accelerometer. the last decade e-lecturing has become more and more popular. We model the distribution of correlation of temporal noise residue in a forged video as a Gaussian mixture model (GMM). We propose a twostep scheme to estimate the model parameters. Consequently, a Bayesian classifier is used to find the optimal threshold value based on the estimated parameters.

A NEW DATA ENCODER AND DECODER SCHEME FOR NETWORK ON CHIPEditor IJMTER
System-on-chip (soc) based system has so many disadvantages in power-dissipation as
well as clock rate while the data transfer from one system to another system in on-chip. At the same
time, a higher operated system does not support the lower operated bus network for data transfer.
However an alternative scheme is proposed for high speed data transfer. But this scheme is limited to
SOCs. Unlike soc, network-on-chip (NOC) has so many advantages for data transfer. It has a special
feature to transfer the data in on-chip named as transitional encoder. Its operation is based on input
transitions. At the same time it supports systems which are higher operated frequencies. In this
project, a low-power encoding scheme is proposed. The proposed system yields lower dynamic
power dissipation due to the reduction of switching activity and coupling switching activity when
compared to existing system. Even-though many factors which is based on power dissipation, the
dynamic power dissipation is only considerable for reasonable advantage. The proposed system is
synthesized using quartus II 9.1 software. Besides, the proposed system will be extended up to
interlink PE communication with help of routers and PE’s which are performed by various
operations. To implement this system in real NOC’s contains the proposed encoders and decoders for
data transfer with regular traffic scenarios should be considered.
A RESEARCH - DEVELOP AN EFFICIENT ALGORITHM TO RECOGNIZE, SEPARATE AND COUNT ...Editor IJMTER
Coins are important part of our life. We use coins in a places like stores, banks, buses, trains
etc. So it becomes a basic need that coins can be sorted, counted automatically. For this, there is
necessary that the coins can be recognized automatically. Automated Coin Recognition System for the
Indian Coins of Rs. 1, 2, 5 and 10 with the rotation invariance. We have taken images from the both

Analysis of VoIP Traffic in WiMAX EnvironmentEditor IJMTER
This document reviews several studies that analyzed the performance of VoIP traffic over WiMAX networks using different VoIP codecs and WiMAX service classes. It summarizes the findings of various papers on how QoS parameters like throughput, delay, jitter compared for codecs like G.711, G.723, G.729 when using the UGS, rtPS, nrtPS and BE service classes. Most studies found that UGS generally performed best for VoIP due to its ability to guarantee bandwidth and minimize jitter and delay, while G.711 typically provided the best voice quality. The document aims to compare the results across different service classes and codecs.
A Hybrid Cloud Approach for Secure Authorized De-DuplicationEditor IJMTER
The cloud backup is used for the personal storage of the people in terms of reducing the
mainlining process and managing the structure and storage space managing process. The challenging
process is the deduplication process in both the local and global backup de-duplications. In the prior
work they only provide the local storage de-duplication or vice versa global storage de-duplication in
terms of improving the storage capacity and the processing time. In this paper, the proposed system
is called as the ALG- Dedupe. It means the Application aware Local-Global Source De-duplication
proposed system to provide the efficient de-duplication process. It can provide the efficient deduplication process with the low system load, shortened backup window, and increased power
efficiency in the user’s personal storage. In the proposed system the large data is partitioned into
smaller part which is called as chunks of data. Here the data may contain the redundancy it will be
avoided before storing into the storage area.
Aging protocols that could incapacitate the InternetEditor IJMTER
The biggest threat to the Internet is the fact that it was never really designed. For e.g., the
BGP protocol is used by Internet routers to exchange information about changes to the Internet's
network topologies. However, it also is among the most fundamentally broken; as Internet routing
information can be poisoned with bogus routing information. Instead, it evolved in fits and start,
thanks to various protocols that have been cobbled together to fulfill the needs of the moment. Few
of protocols from them were designed with security in mind. or if they were sported no more than
was needed to keep out a nosy neighbor, not a malicious attacker. The result is a welter of aging
protocols susceptible to exploit on an Internet scale. Here are six Internet protocols that could stand
to be replaced sooner rather than later or are (mercifully) on the way out.

A CAR POOLING MODEL WITH CMGV AND CMGNV STOCHASTIC VEHICLE TRAVEL TIMESEditor IJMTER
Carpooling (also car-sharing, ride-sharing, lift-sharing), is the sharing of car journeys so
that more than one person travels in a car. It helps to resolve a variety of problems that continue to
plague urban areas, ranging from energy demands and traffic congestion to environmental pollution.
Most of the existing method used stochastic disturbances arising from variations in vehicle travel
times for carpooling. However it doesn’t deal with the unmet demand with uncertain demand of the
vehicle for car pooling. To deal with this the proposed system uses Chance constrained
formulation/Programming (CCP) approach of the problem with stochastic demand and travel time
parameters, under mild assumptions on the distribution of stochastic parameters; and relates it with a
robust optimization approach. Since real problem sizes can be large, it could be difficult to find
optimal solutions within a reasonable period of time. Therefore solution algorithm using tabu
heuristic solution approach is developed to solve the model. Therefore, we constructed a stochastic
carpooling model that considers the in- fluence of stochastic travel times. The model is formulated as
an integer multiple commodity network flow problem. Since real problem sizes can be large, it could
be difficult to find optimal solutions within a reasonable period of time.
Sustainable Construction With Foam Concrete As A Green Green Building MaterialEditor IJMTER
This document discusses the use of foam concrete as a sustainable building material. Foam concrete is produced using cement, fine sand, water, and aluminium powder, which reacts to produce hydrogen gas bubbles that lighten the concrete. It has benefits like lower carbon dioxide emissions in production than traditional concrete, good thermal and sound insulation, fire resistance, and cost-effectiveness. The document reports on tests showing that foam concrete made with quarry dust has higher compressive strength than that made with sand. Strength generally decreases as aluminium powder content increases. Foam concrete is proposed as a sustainable alternative building material.
USE OF ICT IN EDUCATION ONLINE COMPUTER BASED TESTEditor IJMTER
A good education system is required for overall prosperity of a nation. A tremendous
growth in the education sector had made the administration of education institutions complex. Any
researches reveal that the integration of ICT helps to reduce the complexity and enhance the overall
administration of education. This study has been undertaken to identify the various functional areas
to which ICT is deployed for information administration in education institutions and to find the
current extent of usage of ICT in all these functional areas pertaining to information administration.
The various factors that contribute to these functional areas were identified. A theoretical model was
derived and validated.
Textual Data Partitioning with Relationship and Discriminative AnalysisEditor IJMTER
Data partitioning methods are used to partition the data values with similarity. Similarity
measures are used to estimate transaction relationships. Hierarchical clustering model produces tree
structured results. Partitioned clustering produces results in grid format. Text documents are
unstructured data values with high dimensional attributes. Document clustering group ups unlabeled text
documents into meaningful clusters. Traditional clustering methods require cluster count (K) for the
document grouping process. Clustering accuracy degrades drastically with reference to the unsuitable
cluster count.
Textual data elements are divided into two types’ discriminative words and nondiscriminative
words. Only discriminative words are useful for grouping documents. The involvement of
nondiscriminative words confuses the clustering process and leads to poor clustering solution in return.
A variation inference algorithm is used to infer the document collection structure and partition of
document words at the same time. Dirichlet Process Mixture (DPM) model is used to partition
documents. DPM clustering model uses both the data likelihood and the clustering property of the
Dirichlet Process (DP). Dirichlet Process Mixture Model for Feature Partition (DPMFP) is used to
discover the latent cluster structure based on the DPM model. DPMFP clustering is performed without
requiring the number of clusters as input.
Document labels are used to estimate the discriminative word identification process. Concept
relationships are analyzed with Ontology support. Semantic weight model is used for the document
similarity analysis. The system improves the scalability with the support of labels and concept relations
for dimensionality reduction process.
Testing of Matrices Multiplication Methods on Different ProcessorsEditor IJMTER
There are many algorithms we found for matrices multiplication. Until now it has been

complexity can be decreased. This paper focus on the algorithm and its complexity of matrices
multiplication methods.
Malware is a worldwide pandemic. It is designed to damage computer systems without
the knowledge of the owner using the system. Software‟s from reputable vendors also contain
malicious code that affects the system or leaks information‟s to remote servers. Malware‟s includes
computer viruses, spyware, dishonest ad-ware, rootkits, Trojans, dialers etc. Malware detectors are
the primary tools in defense against malware. The quality of such a detector is determined by the
techniques it uses. It is therefore imperative that we study malware detection techniques and
understand their strengths and limitations. This survey examines different types of Malware and
malware detection methods.
SURVEY OF TRUST BASED BLUETOOTH AUTHENTICATION FOR MOBILE DEVICEEditor IJMTER
Practical requirements for securely demonstrating identities between two handheld
devices are an important concern. The adversary can inject a Man-In- The-Middle (MITM) attack to
intrude the protocol. Protocols that employ secret keys require the devices to share private
information in advance, in which it is not feasible in the above scenario. Apart from insecurely
typing passwords into handheld devices or comparing long hexadecimal keys displayed on the
devices’ screen, many other human-verifiable protocols have been proposed in the literature to solve
the problem. Unfortunately, most of these schemes are unsalable to more users. Even when there are
only three entities attempt to agree a session key, these protocols need to be rerun for three times.
So, in the existing method a bipartite and a tripartite authentication protocol is presented using a
temporary confidential channel. Besides, further extend the system into a transitive authentication
protocol that allows multiple handheld devices to establish a conference key securely and efficiently.
But this method detects only the outsider attacks. Method does not consider the insider attacks. So,
in the proposed method trust score based method is introduced which computes the trust values for
the nodes and provide the security. The trust score is computed has a positive influence on the
confidence with which an entity conducts transactions with that node. Network the behavior of the
node will be monitored periodically and its trust value is also updated .So depending on the behavior
of the node in the network trust relation will be established between two nodes.
GLAUCOMA is a chronic eye disease that can damage optic nerve. According to WHO It
is the second leading cause of blindness, and is predicted to affect around 80 million people by 2020.
Development of the disease leads to loss of vision, which occurs increasingly over a long period of
time. As the symptoms only occur when the disease is quite advanced so that glaucoma is called the
silent thief of sight. Glaucoma cannot be cured, but its development can be slowed down by
treatment. Therefore, detecting glaucoma in time is critical. However, many glaucoma patients are
unaware of the disease until it has reached its advanced stage. In this paper, some manual and
automatic methods are discussed to detect glaucoma. Manual analysis of the eye is time consuming
and the accuracy of the parameter measurements also varies with different clinicians. To overcome
these problems with manual analysis, the objective of this survey is to introduce a method to
automatically analyze the ultrasound images of the eye. Automatic analysis of this disease is much
more effective than manual analysis.
Survey: Multipath routing for Wireless Sensor NetworkEditor IJMTER
Reliability is playing very vital role in some application of Wireless Sensor Networks
and multipath routing is one of the ways to increase the probability of reliability. More over energy
consumption is constraint. In this paper, we provide a survey of the state-of-the-art of proposed
multipath routing algorithm for Wireless Sensor Networks. We study the design, analyze the tradeoff
of each design, and overview several presenting algorithms.
Step up DC-DC Impedance source network based PMDC Motor DriveEditor IJMTER
This paper is devoted to the Quasi Z source network based DC Drive. The cascaded
(two-stage) Quasi Z Source network could be derived by the adding of one diode, one inductor,
and two capacitors to the traditional quasi-Z-source inverter The proposed cascaded qZSI inherits all
the advantages of the traditional solution (voltage boost and buck functions in a single stage,
continuous input current, and improved reliability). Moreover, as compared to the conventional qZSI,
the proposed solution reduces the shoot-through duty cycle by over 30% at the same voltage boost
factor. Theoretical analysis of the two-stage qZSI in the shoot-through and non-shoot-through
operating modes is described. The proposed and traditional qZSI-networks are compared. A
prototype of a Quasi Z Source network based DC Drive was built to verify the theoretical
assumptions. The experimental results are presented and analyzed.

Software Quality Analysis Using Mutation Testing SchemeEditor IJMTER
The software test coverage is used measure the safety measures. The safety critical analysis is
carried out for the source code designed in Java language. Testing provides a primary means for
assuring software in safety-critical systems. To demonstrate, particularly to a certification authority, that
sufficient testing has been performed, it is necessary to achieve the test coverage levels recommended or
mandated by safety standards and industry guidelines. Mutation testing provides an alternative or
complementary method of measuring test sufficiency, but has not been widely adopted in the safetycritical industry. The system provides an empirical evaluation of the application of mutation testing to
airborne software systems which have already satisfied the coverage requirements for certification.
The system mutation testing to safety-critical software developed using high-integrity subsets of
C and Ada, identify the most effective mutant types and analyze the root causes of failures in test cases.
Mutation testing could be effective where traditional structural coverage analysis and manual peer
review have failed. They also show that several testing issues have origins beyond the test activity and
this suggests improvements to the requirements definition and coding process. The system also
examines the relationship between program characteristics and mutation survival and considers how
program size can provide a means for targeting test areas most likely to have dormant faults. Industry
feedback is also provided, particularly on how mutation testing can be integrated into a typical
verification life cycle of airborne software. The system also covers the safety and criticality levels of
Java source code.
Software Defect Prediction Using Local and Global AnalysisEditor IJMTER
The software defect factors are used to measure the quality of the software. The software
effort estimation is used to measure the effort required for the software development process. The defect
factor makes an impact on the software development effort. Software development and cost factors are
also decided with reference to the defect and effort factors. The software defects are predicted with
reference to the module information. Module link information are used in the effort estimation process.
Data mining techniques are used in the software analysis process. Clustering techniques are used
in the property grouping process. Rule mining methods are used to learn rules from clustered data
values. The “WHERE” clustering scheme and “WHICH” rule mining scheme are used in the defect
prediction and effort estimation process. The system uses the module information for the defect
prediction and effort estimation process.
The proposed system is designed to improve the defect prediction and effort estimation process.
The Single Objective Genetic Algorithm (SOGA) is used in the clustering process. The rule learning
operations are carried out sing the Apriori algorithm. The system improves the cluster accuracy levels.
The defect prediction and effort estimation accuracy is also improved by the system. The system is
developed using the Java language and Oracle relation database environment.
Software Cost Estimation Using Clustering and Ranking SchemeEditor IJMTER
Software cost estimation is an important task in the software design and development process.
Planning and budgeting tasks are carried out with reference to the software cost values. A variety of
software properties are used in the cost estimation process. Hardware, products, technology and
methodology factors are used in the cost estimation process. The software cost estimation quality is
measured with reference to the accuracy levels.
Software cost estimation is carried out using three types of techniques. They are regression based
model, anology based model and machine learning model. Each model has a set of technique for the
software cost estimation process. 11 cost estimation techniques fewer than 3 different categories are
used in the system. The Attribute Relational File Format (ARFF) is used maintain the software product
property values. The ARFF file is used as the main input for the system.
The proposed system is designed to perform the clustering and ranking of software cost
estimation methods. Non overlapped clustering technique is enhanced with optimal centroid estimation
mechanism. The system improves the clustering and ranking process accuracy. The system produces
efficient ranking results on software cost estimation methods.
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELgerogepatton
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Abstract -- Due to the increasing popularity of video services application in recent days, it is
undesirable to prevent the content leakage on the trusted video delivery and piracy prevention has
been indeed, become critical. In order to preserve content leakage and prevent piracy,
conventional system addressed the issue by proposing the method based on the observation of
streamed traffic throughout the network .Also piracy has hindered the use of open peer to peer
networks for commercial content delivery. Hence the basic idea is to propose an enhanced
dynamic content leakage detection scheme that is robust to the variation of the video lengths. It
enhances the detection performances even in the environment subjected to variation in length of
videos. To detect pirates, identity-based signature and time stamped token have been generated. It
helps to solve piracy without affecting P2P clients so that colluder cannot download the secured
videos. The advantage lies mainly in advanced content availability, low cost and copyright
agreements in protecting the secured videos.
Keywords -- Content Delivery Networks, Content Leakage Detection, Streamed Traffic, Piracy,
Digital Signature.
I. INTRODUCTION
In recent years, popularity of real-time video and streaming application and services over
the internet has increased. Examples: YouTube, Microsoft Network Videos. Most people do not
read as much as they used to, and when they do read, they tend to skim-read, which means the
importance of written copy can be lost or misinterpreted[7].With an abundance of content pushed
to consumers and employees every day, a well-crafted video allows brand or message to stand
out and be clearly understood. The three basic reasons to use video: cost-effectiveness, increased
productivity and consistency [8].
The main uses of videos [9] include Training and Tutorial, where corporate video first
gained prominence with training (service, support, sales, personal development etc.) and
continues to be one of the best uses of video. Online Video is a cost effective substitute for in-
class training. It can also easily integrate video into online training management tools. Share the
knowledge gained at these events by capturing the presentations, demos, interviews,
commentaries etc. on video. Product Demonstrations help to show how product works and
highlight the features that differentiate it from those other competitors. Software screen captures,
3D cut-away, or a high impact demo by a presenter are all excellent ways of showing how

product or service works. Infomercials have been around forever. While they continue to be the
primary focus of web-based parody videos they have remained remarkably resilient over time.
The shopping channel is, in effect, a 24 hour infomercial. If done well, Infomercials can be very
effective at selling certain consumer products.
II. RELATED WORK
In computing, a shared resource, or network share, is a computer resource made available
from one host to other hosts on a computer network. Some examples of shareable resources are
computer programs, data, storage devices, and printers. Network sharing is made possible by
inter-process communication over the network.
Shared resources, also known as network resources, refer to computer data, information,
or hardware devices that can be easily accessed from a remote computer through a local area
network (LAN) or enterprise intranet. Successful shared resource access allows users to operate
as if the shared resource were on their own computer. The most frequently used shared network
environment objects are files, data, multimedia and hardware resources like printers, fax
machines and scanners[10].
The videos with collusive piracy is the main source of intellectual property violations
within the boundary of a P2P network. Paid clients may illegally share copyrighted content files
with unpaid clients (pirates). Such online piracy has hindered the use of open P2P networks for
commercial content delivery. It propose a proactive content poisoning scheme to stop colluders
and pirates from alleged copyright infringements in P2P file sharing. The basic idea is to detect
pirates timely with identity-based signatures and time stamped tokens. The scheme stops
collusive piracy without hurting legitimate P2P clients by targeting poisoning on detected
violators, exclusively[1].
Cisco Data Loss Prevention (DLP) is a data leakage protection solution that helps
organizations assess risk and prevent data loss over the highest points of risk. It safeguards
proprietary information against security threats due to enhanced employee mobility, new
communication channels, and diverse services.
To solve the issues of content leakage, leakage detection scheme have been introduced.
It helps to investigate the performance of the proposed method under a real network
environment with videos of different lengths. The proposed method allows flexible and accurate
streaming content leakage detection independent of the length of the streaming content, which
enhances secured and trusted content delivery[2].
Video streaming application[3] deals with several P2P network is used to build live and
online video streaming services on the internet at low cost. Provide large scale live and on-
demand videos streaming services. The limitation is that no good quality of videos. Videos
playback start tens of second after a user selects a channels.

In order to detect illegal content streaming by using traffic pattern which are constructed
from the amount of traffic routers. To solve burst errors and random errors. It prevent content
leakage from user‘s side. However delay occur due to large length of videos[4].
As an extensible signaling protocol, SIP (Session Initiation Protocol) can be applied in
developing video conference system of conference server and the availability of bandwidth. It
focuses on how to keep conferencing when the number of conference users increases. It
provides a scalable service model for SIP-based video conference. The main disadvantage is
Cost Expensive, Low resolution[5].
IPSec VPNs is developed to implement Internet security connection using Virtual Private
Network. It helps in performing of video conference in real time multi-media traffic and secure
connection links. Quality of video will be good. However due to heavy network, traffic loads.
Encryption require high amount of CPU and memory [6].
Thus from the above it is concluded that content leakage and piracy prevention is a major
issues. Hence it is proposed to recover content leakage and piracy for the trusted videos.
III. FRAMEWORK
In the framework, overall process of the design is being explained. The owner or
distributor uploads the compressed video in the server. He uploads the copyright videos
containing token, digital signature. Then the user is one who downloads the video. While he
downloads the video, he needs to send request to server containing token, timestamp, signature
.After the token and signature is being verified, the user can download that video in a
compressed format. If the token or signature is not same, the videos can’t be downloaded. Thus
the piracy of video is prevented.
When user uploads many videos in the server, content is being leaked due to the traffic of
network. It can be identified based on the length of the video. Also when many users download
the particular video, content is being leaked. So that the user can’t download the entire complete
video. It should be avoided by leakage detection process. When leakage detection algorithm is
being applied, content leakage is recovered. Thus the content leakage due to traffic of network
can be avoided.
The overall architecture diagram for the content leakage and piracy prevention is given
below.
The methodology of the proposed framework is based on the following module.
1. Video Compression
2. Piracy Prevention
3. Content Leakage Detection
4. Content Leakage Recovery

3.1 VIDEO COMPRESSION
Video is being compressed by arithmetic length encoding. The original videos are framed
into 8 * 8 blocks. Then the blocks are segmented based on discrete cosine transform. By
applying quantization videos is being compressed. To decompress the videos, inverse the

discrete cosine transforms. Apply quantization. With the help of decompressed algorithm such as
arithmetic length decoding, original video can be obtained.
3.2 DIGITAL SIGNATURE
Pseudo code:
Token Generation
Input: Digital Receipt
Output: Encrypted Authorization Token T
If Receipt is invalid
Deny the request;
Else
λ= Decrypt (Receipt);
P = Observe (Requestor)
K = privatekeyRequest(p);
Token T = Ownersign(f,p,ts);
Reply = { k,p,Ts, t}
SendToRequestor{ Encrypt(Reply)}
Endif
Digital signature is used to maintain piracy prevention in authorized content. First, both
distributor and user are fully trusted. Their public keys are known to all videos. The piracy
prevention consists of two integral parts: token generation and authorization verification. All
videos are encrypted using the session key assigned by the transaction server at purchase time.
A token is a digital signature of a three tuple :{ endpoint, file ID, timestamp} signed by
the private key of the content owner. Since bootstrap agent has a copy of the digital receipt sent
by transaction server, verifying the receipt is thus done locally. The Decrypt (Receipt) function
decrypts the digital receipt to identify the file .The Observe (requestor) returns with the
endpoint address.

Φ(λ,p)=file index for file at end point p
Output: Peer authorization status
True – Authorization granted
False – Authorization Denied
The Owner Sign function returns with a token. Upon receiving a private key, the
bootstrap agent digitally signs the file ID, endpoint address, and timestamp to create the token.
The reply message contains a four tuple :{ endpoint address, private key, timestamp, token}.
After token is being generated, user send request to download a video. A download
request include a token, file index, timestamp, and the digital signature. If any of the fields are
missing, the download is stopped. A download user must have a valid token T and signature S.
Two pieces of critical information are needed: public key and the endpoint address. It verifies
both token T and signature S. Token also contains the file index information and timestamp
indicating the expiration time of the token. The Parse (input) extracts timestamp, token,
signature, and index from a download request.
3.3 CONTENT LEAKAGE
Due to upload of n number of videos, distributor finds content leakage in the network.
Also when user downloads video from the server, the heavy traffic in network arises. It leads to
packet loss, jitter and time delay. It leads to content leakage in downloading the videos. Hence it
is necessary to solve content leakage.
Throughout the video streaming process, the changes of the amount of traffic appear as a
unique waveform specifies to the content. Thus by getting this information retrieved in the
network, the content leakage can be detected. Pattern generation algorithm is used to match the
video from user‘s side and server ‘s side. Based on the time slot , the content leakage can be
detected. By applying pattern matching algorithm, content leakage can be recovered.
3.4 CONTENT LEAKAGE RECOVERY
Content can be recovered by determination of the decision threshold for detecting
leakage. The steps of content recovery are as follows.
1. Threshold determination process
2. Comparison based on traffic pattern
3. Cost evaluation
In threshold determination, from the original video a portion of video being taken and
generate the corresponding traffic pattern. These patterns are compared with the original traffic
pattern to perform sampling of the length of the videos. Then the curve is being generated from
the observed traffic pattern. It is necessary to compare the adjusted degree of similarity to the

decision threshold to the original video and recover the leakage. Then the cost is being evaluated
for the above process.
VI. CONCLUSION AND FUTURE WORKS
The content leakage of video is being detected and piracy prevention has been proposed
for the compressed videos. In future it may be enhanced to detect content leakage for online
video conferencing.
