Abstract :
A robust copyright protection scheme for digital images is proposed in the paper. In the proposed scheme, the watermark does not require to be embedded into the protected image but is used to generate a secret image by addition operations over finite groups. Then the secret image is registered to certified authority (CA) for further protection. Color images can be used as the watermark is the most major characteristic of the scheme. Experimental results show that the proposed scheme not only can clearly verify the copyright of the digital image, but also is robust to withstand many image processing attacks.
