A verifiable visual cryptography scheme based on XOR algorithm
Yanyan Han, Wencai He, Haocong Dong, Juan Liu · 2012
Visual Cryptography is the same as other secret sharing schemes, which also has the problem of deception. The cheater can destroy the recovery of secret image or gain secret information by cheating through making a counterfeiter of share images. In this paper, in order to resolve the problem of deception, we proposed a verifiable visual cryptography scheme can ensure that the secret image can be visually revealed correctly. This scheme can check and verify the accuracy and truthfulness of every share image, which is simple to decrypt and without any pixel expansion.
