An Image Database Security Using Multilayer Multi Share Visual Cryptography

Apurva A. Mohod | Prof. Komal B. Bijwe ^[2]

Abstract: In this paper, we are presenting a novel technique of multilayer multi share Visual Cryptography in which image is encrypted at multiple levels using sterilization algorithm. In encryption secret image is converted into monochromatic image i. e. Red, Green and Blue channels are separated and each channel encrypted using sterilization algorithm. It is a bitwise operation. Shares obtain at each level are stored in database using that database image is encrypted to further levels. For decryption all the shares are need to be superimposed in proper sequence using desterilization algorithm. By stacking shares with same keys, original secret image is revealed.
