Visual Cryptography Scheme (VCS) is a cryptographic technique which allows visual information to be encrypted in such a way that the decryption can be performed by the human visual system without the aid of computers. As network technology has been greatly advanced, much information is transmitted via the internet conveniently and rapidly. At the same time, the security issue is a crucial problem in the transmission process. This method aims to build a cryptosystem that would be able to encrypt any image, so that the encrypted image when intercepted by any person with malicious intentions during the time of transmission of the image is unable to decipher the image.
