An HVS-Based JPEG Image Watermarking Method for Copyright Protection

A practical watermarking method for the copyright protection of JPEG image is proposed in this paper. By operating the pixel matrix of depressed the JPEG image, the authors can use the DCT coefficients to embed the watermark. The strength of watermark can be controlled by visual masking and analysis of the quantization condition during the embedding of watermark, no original image is needed when extracting the watermark. The experimental results show that the proposed scheme can achieve excellent robustness to common image processing methods and some attacks in favor of protecting the copyright of JPEG image.
