Abstract

In this paper, we propose a new image watermark algorithm of information hiding scheme based on chaotic encryption. Chaotic sequence is regarded as a noise-like spread sequence, and the secret signal to be transmitted is modulated and hidden in the carrier image as white noise to implement secure communication. The encryption principle of new algorithm is firstly presented in this paper, and the merits of new scheme are quantitatively analyzed by defining integrality and imperceptibility of image information. The results of computer simulation are described in the end.
