A Novel Access Control Scheme for Multimedia Content with Modified Hash Chain
نویسندگان
چکیده
With the continuing growth in network technology, the exchange of digital images and audio as well as text has become very common regardless of whether the digital content is used for commercial purpose or not. Since such digital content is easily duplicated and re-distributed, protecting copyrights and privacy is an important issue. For the protection of digital content, access control based on naïve encryption (encrypting the whole content) (1) or media-aware encryption (2–6) has been studied widely.

A standard Interactive Multimedia eBook Generator Engine for e-Learning Process
Introduction: Using standard authoring tools is essential to promote E-Learning in teaching-learning process. Learning content in medical sciences often consists of multimedia elements. On the other hand, it is frequently required to revise and update the medical content. Hence, access to the authoring tools that can encompass multimedia elements and allow easy content revision is helpful in e-...
متن کاملA System for End-to-End Authentication of Adaptive Multimedia Content
We present a multimedia content delivery system that preserves the end-to-end authenticity of original content while allowing content adaptation by intermediaries. Our system utilizes a novel multi-hop signature scheme using Merkle trees that permits selective element removal and insertion. To permit secure element insertion we introduce the notion of a placeholder. We propose a computationally...
متن کاملRobust hash-based image watermarking with resistance to geometric distortions and watermark-estimation attack
Digital watermarking provides a feasible way for copyright protection of multimedia. The major disadvantage of the existing methods is their poor resistance to both extensive geometric distortions and watermark-estimation attack (WEA). In view of this fact, our goal of this paper is to propose a robust image watermarking scheme that can withstand geometric distortions and WEA. Our scheme is mai...
متن کاملConstructing Key Assignment Schemes from Chain Partitions
In considering a problem in access control for scalable multimedia formats, we have developed new methods for constructing a key assignment scheme. Our first contribution is to improve an existing cryptographic access control mechanism for scalable multimedia formats. We then show how our methods can be applied to a chain partition to develop alternative mechanisms for scalable multimedia forma...
متن کاملA Multi-level Access Control Scheme For Multimedia
Security of multimedia database systems becomes a critical problem, especially with the proliferation of multimedia data and applications. One of the most challenging issues is to provide a content-based multimedia database access control that efficiently handles different user’s access with possible fine-grained restrictions at a specific level of the multimedia data. However, the realization ...
