Abstract :
A method of constructing basic matrices for XOR visual cryptography is proposed in this paper, which designs one kind of threshold scheme by constructing recursion operator and integrating application of recursive idea. Experimental results show that the scheme constructed in this paper not only recovers the secret image sufficiently, but also resolves the problem of large pixel expansion upon XOR visual cryptography.
