Visual cryptography is a new technique which provides information security (such as data security, confidentiality, entity authentication, copy right of image, access control identification of binary and normal images) by using simple algorithm of cryptography rather than complex algorithm of traditional cryptography. In visual cryptography the encryption process is done in such a way that the decryption process is done easily by human visual system without the aid of any complex computer programming algorithm. Visual cryptography encrypt secret image into the numbers of share such that by stacking the sufficient number of share reveals the secret image.
