Abstract -
Visual Cryptography is a special paradigm for cryptography schemes that allows the decoding of concealed images without any cryptographic computation. This paper proposes an interesting method for copyright protection for digital images based on visual cryptography. The proposed method having encoding of Most Significant bits of host image which is to be copyrighted, to generating a master image share. The master share is encoded with a secret image which is called copyright image to form another share called ownership share. The master share is placed in a central authority and ownership share is retained by the copyright owner. In case of any debate, the master shares and ownership shares can be stacked together to generate the secret image verifying the ownership about the host image. The important factor of our procedure is that we do not disturb the host image either during copyright generation or during copyright verification. Size of secret image is not a problem in the proposed method.
