A Novel Image Steganography Using Chaotic Map and Visual Model

摘要：

A novel image steganography method using chaotic map and human visual model is presented in DCT domain. Firstly each 8 ×8 image block is performed Discrete Cosine Transform, then the location of image block that is embedded secret message is determined by the chaotic map. Finally the secret message is em-bedded adaptively in the usable middle frequency co-efficient pairs judged by Just Noticeable Differ-ence(JND). Simulation results show that the algorithm has a high capacity and a good invisibility, moreover it is robust for the common image processing like JPEG compression and cropping.
