摘要：
A blind digital watermark method based on singular value decomposition (SVD) and Chaos was proposed in this paper. Firstly the watermark was encrypted by Tent chaotic sequence, and then the cover image is decomposed by SVD, the encrypted watermark is embedded into the singular values of the cover image, and the watermark can be extracted without the original image. The experimental results indicate that the proposed method is robust against attacking such as JPEG compression, addition of noise, cropping, rotation and contrast adjustment.
