Abstract

Visual cryptography technique encipher the visual information in such a way, that decipher can be performed by human visual system without any complex decoding process . As visual cryptography, is a secure tactics for transmitting visual information but, if anyone gets access to all shares, he/she can reveal out the secret easily. In this paper a more impregnable visual cryptography scheme is proposed. This technique first encrypts the secret using a symmetric key and then divides the secret into shares. After stacking of shares, secret does not appear, until the symmetric key is not known. This technique is proposed for binary images. Here the symmetric key used for encryption and decryption is a small binary image.

Keywords
