Abstract

The cheating is main issue while transferring the secret image against the owner. To avoid this Visual Cryptography novel method technique of cryptography is used. In this we divide secret images into multiple shares and are distributed to various entities. To get back the secret image we need all the shares. Using different operations we can reconstructed by superimposing these share. The pixel expansion and noise at output is a major drawback in Traditional. The major problem is cheating between shareholders cheating owners and between them. To avoid these limitation sealing algorithm with two application of visual cryptography (VC) are MIVC and EVC is used. The image will be changed into halftoned representation before sealing the algorithm. For this we are using SBR technique. The output overcomes common limitation likes pixel expansion and clarity of image along with this the system also provides a cheating prevention mechanism. Two secret image can be send at the same time by connecting them into halftonedrepresentations which are partitioned as totally three shares.
