Abstract :
According to the characteristics of human vision system (HVS), a color image watermark algorithm based on chaos encrypting is proposed. The algorithm makes use of merits of Lorenz chaos system encrypting to embed digital watermark into color image, and extract the digital watermark from color image effectively. The simulation results of this process indicate that the algorithm can satisfy with the requirements of robustness and invisibility in the same time
