A Survey on Multimedia Content Protection Mechanisms

Cloud computing has emerged to influence multimedia content providers like Disney to render their multimedia services. When content providers use the public cloud, there are chances to have pirated copies further leading to a loss in revenues. At the same time, technological advancements regarding content recording and hosting made it easy to duplicate genuine multimedia objects. This problem has increased with increased usage of a cloud platform for rendering multimedia content to users across the globe. Therefore it is essential to have mechanisms to detect video copy, discover copyright infringement of multimedia content and protect the interests of genuine content providers. It is a challenging and computationally expensive problem to be addressed considering the exponential growth of multimedia content over the internet. In this paper, we surveyed multimedia-content protection mechanisms which throw light on different kinds of multimedia, multimedia content modification methods, and techniques to protect intellectual property from abuse and copyright infringement. It also focuses on challenges involved in protecting multimedia content and the research gaps in the area of cloud-based multimedia content protection

Survey on: Multimedia Content Protection using Cloud

There is need for large scale multimedia content protection system. There are varying workloads for which cloud infrastructure provide cost efficiency, rapid development and scalability. Data protection along with security whole together contribute to the success of cloud. Security is very important in today�s online world. It is widely accepted that cloud computing has the unrealized ability to make privacy disable. The cloud is been chosen because it provides some security features. The greatest challenge is to process data securely in cloud. One of the factor leading to high performance in cloud is nothing but the security. For the protection purpose, a system for multimedia content protection on cloud infrastructure is presented. The system can be used to protect various multimedia contents such as 2D video and 3D videos, graphics which is animated, images, audios clips etc. Multimedia is the combination of data, text, image, audio, or video in a single application. The system can be deployed on both public cloud and private cloud. Two major components to be considered are method to create signatures of 3D videos and matching engine for multimedia objects. Depth signals are captured from 3D videos. This system detects the duplicated multimedia content that is copyright material in an online environment

Multimedia Protection using Content and Embedded Fingerprints

Improved digital connectivity has made the Internet an important medium for multimedia distribution and consumption in recent years. At the same time, this increased proliferation of multimedia has raised significant challenges in secure multimedia distribution and intellectual property protection. This dissertation examines two complementary aspects of the multimedia protection problem that utilize content fingerprints and embedded collusion-resistant fingerprints. The first aspect considered is the automated identification of multimedia using content fingerprints, which is emerging as an important tool for detecting copyright violations on user generated content websites. A content fingerprint is a compact identifier that captures robust and distinctive properties of multimedia content, which can be used for uniquely identifying the multimedia object. In this dissertation, we describe a modular framework for theoretical modeling and analysis of content fingerprinting techniques. Based on this framework, we analyze the impact of distortions in the features on the corresponding fingerprints and also consider the problem of designing a suitable quantizer for encoding the features in order to improve the identification accuracy. The interaction between the fingerprint designer and a malicious adversary seeking to evade detection is studied under a game-theoretic framework and optimal strategies for both parties are derived. We then focus on analyzing and understanding the matching process at the fingerprint level. Models for fingerprints with different types of correlations are developed and the identification accuracy under each model is examined. Through this analysis we obtain useful guidelines for designing practical systems and also uncover connections to other areas of research. A complementary problem considered in this dissertation concerns tracing the users responsible for unauthorized redistribution of multimedia. Collusion-resistant fingerprints, which are signals that uniquely identify the recipient, are proactively embedded in the multimedia before redistribution and can be used for identifying the malicious users. We study the problem of designing collusion resistant fingerprints for embedding in compressed multimedia. Our study indicates that directly adapting traditional fingerprinting techniques to this new setting of compressed multimedia results in low collusion resistance. To withstand attacks, we propose an anti-collusion dithering technique for embedding fingerprints that significantly improves the collusion resistance compared to traditional fingerprints

Distribution of copyrighted multimedia objects by way of uploading individuals to online hosting sites can effect in primary inadequate revenues for content designers. Systems needed to discover clones of multimedia objects are difficult and important. We advise a manuscript the idea of important multimedia content protection systems.  We concentrate on the method of safeguarding multimedia content, that's content-based copy recognition by which signatures are removed original objects. Our physiques for multimedia content protection finds out unlawfully made copies of multimedia objects on the web. Our design attains fast employment of content protection systems, since it is according to cloud infrastructures that provide computing hardware furthermore to software sources. It's two new components as being a approach to generate signatures of three-dimensional and distributed matching engine for multimedia objects.
