A image zero-watermarking scheme for resist geometric attacks
Peng Dai-yuan · Information technology newsletter · 2007
A zero-watermarking for resist geometric attacks is proposed.Without altering the data of the image,the scheme builds the watermarking using geometric moment invariance,the scheme can effectively solve the contradiction between robustness and invisibility of the watermarking.It has been proved to have strong robustness to resist geometric transformation and common image processing by the experiments.
