SYSTEM AND METHOD FOR REAL-TIME VERIFICATION OF CLOCK SYNCHRONISATION-BASED DYNAMIC PASSWORD ANTI-COUNTERFEITING TAG VALIDITY

摘要

The invention discloses a kind of clock synchronized model dynamic password antifalsification label real-time verification of validity system and methods, including electronic module tag, user's checking terminal module and authentication service module; Electronic module tag is for generating dynamic password data and showing; User's checking terminal module acquires the image data of the dynamic password data that electronic module tag generates and electronic module tag ID number, after being analyzed and processed, text-type data are obtained, authentication service module is then sent by internet internet by text-type data; After authentication service module receives text-type data, by calculating and verifying, obtain the first dynamic password data generating algorithm of electronic module tag and the second whether consistent result of dynamic password data generating algorithm of authentication service module, user's checking terminal module is returned, judges electronic module tag legitimacy. The present invention improves personal management and the safety of clock synchronized model dynamic password antifalsification label real-time verification of validity system.
