XOR algorithm can be used to improve the recovery effects of visual cryptography scheme. In this paper, we present a multi-secret visual cryptography scheme by using the matrices of the (k, k)-VCS. We can reveal multiple secret images perfectly by the XOR algorithm and shifting operation on the shares. The visual qualities of recovered images are ideal without any pixel expansion.
