Abstract :
In this paper, a new version of wavelet digital watermark based on chaotic sequence is presented. In satisfying the constraint conditions of distortion, the intensity of watermark is self-adaptive, adjusted with the PSNR and the length of watermark. The existence of watermark can be detected by public key without the original image. The experiment shows that the proposed algorithm is robust for common signal processing and geometric distortion.
