Abstract
This paper proposes a new blind color images watermarking scheme based on SVD and DNA sequences, in which a color watermark is embedded into a color host image for copyright protection. Firstly, the color watermark is encrypted by using DNA encoding and CML. Secondly, the color host image is partitioned into 4i¾?×i¾?4 non-overlapping pixel blocks and then the SVD transform is performed on each selected pixel block. Finally, the DNA sequence watermark encrypted watermark is embedded into the host image by modifying the matrix V. The watermark can be extracted from the watermarked image without resorting to the original host image and the original watermark. The experimental results show that the proposed watermarking scheme has not only good transparency, but strong robustness against the common image processing attacks and geometric attacks.
