Lossless digital watermarking scheme for image maps

A lossless digital watermarking scheme, which was zero- perturbation on the content and graphics for the digital image maps, is proposed. During the simulation, the scheme has been utilized to model the copyright protection program as a commerce application. Compared to the traditional digital watermarking schemes, our scheme operates in redundancy areas of maps and is scalable to topology changes. Experimental results show that, with respect to the geometric attacks and image transformed, the performance of our scheme is better than the classical algorithms based space or frequency domain with much lower complexity.
