Image Encryption Using a Chaotic/Hyperchaotic Multidimensional Discrete System,urity. This chapter introduces a simplified and fast chaos-based scheme for multimedia data encryption and in particular for image security by a cipher application. The encryption algorithm is based on an extracted N-dimension (N-D) discrete time map. This considered chaotic/hyperchaotic discrete sy

Video Cryptosystem Using Chaotic Systems,etc.), information exchanged have become the digital privacy of users. The use of the word privacy explains the most valuable data (or information) for people. In this context, video data represents the most exchanged information between users given the ease offered by Information and Communication
