A novel watermarking method resistant to copy attack
Xiao-Li Niu, Ju Liu, Jiande Sun · Journal of Shandong University · 2006
A novel watermarking method with digital signature is proposed.That is to say,digital signature is embedded to the host image as watermark.The digital signature is obtained based on independent component analysis(ICA).The simulations show the robustness of this method,which can resist not only common image processing but also copy attack.
