| Abstract: | This paper discusses the way to encrypt and decrypt graphic signal by chaos sequence theory. It provides the technology of wavelet-chaos digital watermarking algorithm,including digital watermark embedding algorithm and implementation steps,watermark extraction process and analysis of algorithm parameters. It designs the simulation system on wavelet-chaos digital watermarking algorithm and carries out some experiments on it. The results show that this digital watermark technique has the nature of concealmen... |
