By reversing secret images, a novel multi-secret visual cryptography scheme is presented in this paper. During the secret sharing process, the correlative matrices are designed to encode multiple images into two ring shares. Compared with the previous ones, the proposed scheme makes the number of secret images not restricted and has obviously improved the pixel expansion and the relative difference.
