Sensitive Digital Image Watermarking for Copyright Protection
In this paper, a watermark hiding scheme for copyright protection of sensitive images is proposed. The concept of Visual Cryptography is used, so that the original host image is not altered. The proposed scheme aims at improving the security of the related schemes. The scheme also reduces the size of codebook and size of shares, to be used in watermark hiding process. This is achieved by adapting the concept of Pair-Wise Visual Cryptography (PWVC). The simulation results reveal that the proposed scheme has good robustness to a range of image processing attacks.
