Robust copyright-protection scheme based on visual secret sharing and Bose–Chaudhuri–Hocquenghem code techniques
2012
Journal of Electronic Imaging (JEI)
A robust copyright scheme for image protection based on visual secret sharing (VSS) and Bose-Chaudhuri-Hocquenghem (BCH) code techniques is proposed. This scheme not only maintains the quality of a host image without the change of any pixel value but also generates a meaningful ownership share to improve the management of image copyright. In addition, no codebook is required to store, and the watermark size is independent of the host image. The robustness of watermarking can be enhanced by BCH
