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...
This paper proposes effective digital watermarking scheme to hide information in binary image. The original image is not needed when retrieving the digital watermark and a key is used to protect the hidden information. In order to produce little annoying noise as possible to the binary image, this scheme uses the features of Human Visual System in binary image. Finally we give details on how to implement...
Visual attention model is a hotspot in the field of multimedia understanding. It is quite helpful for multimedia processing especially in the case that the human vision should be considered. In this paper, a novel information hiding algorithm based on Stentiford visual attention model is proposed. By embedding less information in sensitive region, the invisibility of image with hidden information...
