Abstract
This paper proposes an algorithm of image digital watermarking based on chaotic encryption and SVD. In this algorithm, cover image is transformed into 8 × 8 blocks using DCT and we can get a transform matrix. SVD is used on the matrix. At the same time, the watermark image is encrypted using chaos sequence. Then the singular values of cover image are used to add watermark value to embed watermark. Experimental results show that this algorithm has high security, strong anti-interference and better visual masking.
