Visual Cryptography for Image Security

Abstract: Cryptography secures the data during the interaction between different systems. The attackers may use the opportunities to attack the data within the database. Therefore, the security of image is of high importance. In this idea, a private image is bifurcated into two shares of images and these images to be displayed when the two share images are available together; photos of sole share cannot reveal the identity of the actual image. To achieve this, Visual Cryptography is used. There are various dimensions on which VCS performance relay, i.e., accuracy, brightness, pixel widening, security, computer complexity, productive sharing is logical or pointless, a kind of private image. This process encrypts a private image into stocks so that it can collect a sufficient number of shares produces a private image. This project uses VC of coloured images in a biometric application.
