Security-Enhanced Visual Cryptography Schemes With Recursion

Debashis Sanki , Dr. Nisarg Gandhewar


Security is one of the key parameters in visual cryptography schemes. Security is satisfied if each share reveals no information of the original image and the original image cannot be reconstructed if there are fewer than k shares collected. This article presents a novel method for security-enhanced visual cryptography scheme called recursive visual cryptography scheme. In this method, the secret image is encoded into shares and subshares in a recursive manner. By using recursion, the security and reliability of the visual cryptography scheme can be greatly improved.
