Verifiability of Visual Cryptography Based on Operating Scheme

Existing visual cryptography algorithm is mainly based on ideal environment,so there would be some security problems in the specific implementation.To solve these problems,a verification process in the visual cryptography scheme is proposed,and a visual cryptography scheme is designed based on the verification of the operating multi-secret sharing scheme.The program mainly uses a different set of authorization the authentication identity secret image,and combine with the message digest algorithm further ensure the security of the scheme,the last instance of the design and simulation of the scheme.The scheme solves the security problems exist in the visual cryptography scheme,and through improved it can be applied to identity authentication or the other fields of information security.
