Visual Cryptography is a new cryptographic technique which allows Visual information (e.g. printed text, picture) to be encrypted in such a way that their decryption can be performed by the human visual system, without any complex cryptographic algorithms. images is proposed in this paper. In generating the shares for the multiple images, the correlative matrices are designed to encode them into two ring shares. Different from conve scheme has no restriction on the number of secret images and has obviously improved the pixel expansion and the relative difference.
