A technique for digital steganography using chaotic maps

摘要: Chaos has been applied extensively in secure communication over the last decade, but most of chaotic security protocols defined, are cryptographically weak or slow to compute. Also, study phenomena as application area is not discussed detail. In this paper, we have intensely studied chaos, their influence communications and proposed a steganography technique spatial domain for digital images based upon maps. By applying chaos effectively communication, strength overall anticipated algorithm increased significant level. addition, few statistical analyses such correlation, entropy, energy, contrast, homogeneity, peak signal noise ratio, mean square error also carried out shown that it can survive against various differential attacks known message attack, cover stego only attack.
