A Joint Encryption and Watermarking System

B. Santosh Kumar; T. Geetamma

Multimedia and communication technologies offers new means of sharing and remote access to data. In any information systems data confidentiality, authentication, integrity and non repudiation services are usually required. In this paper, a joint encryption/ watermarking system is for the purpose of protecting images. It merges a chaotic mapping, an encryption algorithm which is a block cipher algorithm (e.g., AES) and a substitutive blind and non-blind watermarking algorithms based on DWT {&} DCT.
