Abstract
A new double Zero-watermarking method based on frequency domain is proposed in this paper. It uses the main message of an image to construct the watermark, hence keep the best invisibility. In the method, DCT and DWT are applied to enhance the quality for resisting attacks. It solves the problem that one type of watermarks can not detect all the attacks and increases the safety by encrypting a chaotic sequence. We proved the robustness of the method by experiments.
