Multimedia Encryption Using Recursive Sequences

Providing security for multimedia data has become an §important issue for individuals, companies and §governments. Traditional cryptographic methods for§multimedia security tend to add a significant amount§of overhead to achieve quality encryption levels.§This additional overhead is not conducive to §processing large amounts of data in real-time§applications. Recursive sequence based multimedia§encryption theory can meet the stringent performance§requirements for real-time multimedia applications,§while achieving different levels of security. This§book focuses on presenting efficient encryption §approaches that are suitable for real-time §applications. It is intended to be used by§individuals interested in privacy, copyright§protection, and security of digital information. §Features: (1) Present a straightforward multimedia §encryption system that can encrypt different types §of multimedia data using different key-dependant §recursive sequences. (2) Present multimedia§encryption techniques using general 2D or 3D §recursive sequence transforms. (3) Analyze and §compare security issues of several multimedia §encryption methods based on recursive sequences.
