It is a technique that is used to hide the confidential information in images; this is made in such a way that it can be decrypted with the help of human visual system. Here decryption happens without any complex cryptographic calculations, Human Visual System is used to decrypt the encrypted data. Cryptographic computation is required for encryption technique to divide into number of shares. In Visual Cryptographic technique k-n secret share is a special technique where at least a group of k shares out of n shares reveals the confidential information, less of it will reveal no information
