Sensitive Digital Image Watermarking for Copyright Protection

Surekha Benguluri, G. N. Swamy
2013 International Journal of Network Security  
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 simulation results reveal that the proposed scheme has good robustness to a range of image processing attacks.  ...  Hence, such schemes can't be used for copyright protection. To overcome this drawback, Hsu et al.  ...
