%X By constructing the optimization model for visual cryptography based on group structure,designed a XOR-based threshold scheme. In this scheme,translated the problem of basic matrix construction to evaluation of probability, and generated the shares by choosing encryption rule with probability-matrix. The scheme not only improves the contrast greatly, but also has no pixel expansion.
