Abstract


Since that traditional tagged visual cryptography scheme (TVCS) can only hide only one secret image, this paper presents a multi-secret visual cryptography scheme with tag information. By adopting the concept of random grids (RG) to construct the basic share images of secret images and the tag images, and then combined them in the form of probability to generate the final shared images. When folding up each share image, we can observe the tag information. What’s more, it can reveal multiple secret images by simple flip operation which increases the amount of secret information. To verify the security and effectiveness of the proposed scheme, we present the theoretically analysis while the simulation results show that the proposed scheme works well.
