摘要：

Digital watermarking is deemed as a novel technique for copyright of digital products protecting and has aroused extensive interests in recent years. Based on the properties of the Hadamard transform and the singular value decomposition (SVD), this paper proposes a novel watermarking algorithm, the experimental results show that the watermarking algorithm has good transparency and robust, especially against the geometrical operations and JPEG lossy compression.
