摘要：
As an attack to digital watermark, copy attack has an important impact oil the application of watermark in copyright protection. In the proposed algorithm, both the image signature describing the original image uniquely and the watermark are embedded into the original image synchronously. And the resistance to copy attack can be realized by verifying the extracted signature. In addition, Using independent component analysis (ICA), the watermark and the signature can be extracted blindly. Experimental results indicate that the watermark call survive copy attack as well as common image processing.
