BASED ON CHAOS THEORY
Keyword Video encryption Video encryption Abstract The security of multimedia data is more and more important for multimedia commerce. The encryption algorithms developed to secure text data may not be suitable to multimedia applications because of large data sizes and real time constraint. Different from military secrets or financial information, multimedia videos the information rate of multimedia videos is very high, but information value is very low. In the literatures, some existing light weight multimedia encryption techniques had been developed to avoid the exposure of multimedia content. To break such encryption code is much more expensive than to buy the programs.
In recent years, the Chaos has been applied to the cryptography. This thesis is intended to take advantage of the features of the chaotic sequences to encrypt the video. We propose a chaos-based partial format compliant MPEG video encryption algorithm. Finally, the effectiveness of the proposed algorithm is demonstrated by software implementation.
