With the increase in computer technology and the development of networks, the transmission of images becomes a daily operation. For the security of secret images cryptosystems such as DES and AES have been proposed. But both are expensive. Visual cryptography, is a scheme that divides a secret image into several shares, many researches about visual secret sharing and its applications have been recently proposed. Unfortunately, the cheating attack in which evil participants cheat the honest one(s) by making a fake share image has come into existence.
