摘要：

The copyright protection of digital content is one of the aims of digital right management (DRM), among which digital watermarking is one of the key supporting technologies. This paper proposes a robust zero-watermark algorithm, which produces the zero-watermark sequence according to the parity of the first digit of the biggest singular value in every block. It essentially doesn't embed any watermark in the original image, thus the watermarked image is the same as its original counterpart. Experimental results show that it has good robustness against various attacks. Moreover, its computation is so low that it is easy to be applied into the practice of digital rights management.
