%X Aiming at the large pixel expansion and low relative difference among the existing multi-secret visual cryptography schemes, starting with the relationship between the pixel expansion and the number of secret images, this paper proposed a XOR-based 2, 2, n multi-secret visual cryptography scheme through the relation algorithm and the share algorithm. This scheme could reconstructed any amount of secret images not only with the XOR operation but also with the OR operation. The experimental results demonstrate that the pixel expansion and relative difference are improved compared with the previous schemes.
