- 摘要：
- Digital watermarking is a technique that can embed identity information and secrecy information into images. For copyright protection and content authentication of digital color image, A Blind Watermarking Algorithm for Color Image based on Singular Value quantization (SVD) in DWT Domain is proposed in this paper. Firstly, the blue component of the original color image is decomposed with DWT, then, the low-frequency coefficients are transformed by block-SVD, and a binary watermark scrambled by logistic chaotic is embedded by quantizing the singular values of primitive image. The watermark is extracted without the original image. The experiment results show that the algorithm is invisible and strongly robust for the common image processing techniques.
