Executive Summary

In cryptography, Encryption is the technique which converts the data into a cipher text that cannot be easily understood by illegal people. Decryption is the method of converting encrypted data into its original. Visual Cryptography (VC) is used to hide secrets in images and decrypted by the human visual scheme if the key image matches. It is unfeasible to recover that secret from one of those shares. The authors can use the techniques for any number of shares. Here, they implement it for two shares. It can be used in number of applications like remote electronic voting, biometric authentication, banking customer identification, message concealment, etc.
