Secret Image Enhanced Sharing Using Visual Cryptography

In the conventional visual cryptographic scheme, an image is divided into several image shares, which are distributed among the members of a group, and the original image is retrieved by combining the shares of all the members. This secret image becomes accessible to every individual member and there is an inherent risk of any one of the members in the group using the valuable information for illegal purposes as an intruder. To overcome this problem, the proposed algorithm Secret Image Enhanced Sharing using Visual Cryptography (SIESVC) diligently facilitates any member in the group to retrieve either only a part or the complete secret image based purely on his access privilege rights only.
