IRIS KEY SYSTEM FOR DOOR LOCK AND ITS SECURITY METHOD BY COMPARING SOURCE IRIS CODE AND REFERENCE IRIS CODE

摘要

PURPOSE: An iris key system and its security method are provided to compare a source iris code and a reference iris code, and to have a portable iris security key device capable of separating from a door lock. CONSTITUTION: The system comprises an iris key system(200) and a door lock(100). The iris key system(200) includes a fixed memory(230), a temporary memory(210) and a security driver(220). The fixed memory(230) stores an iris key number fixedly, and the temporary memory(210) stores an iris key number temporarily. The security driver(220) copies an iris key number stored at the fixed memory(230), and records the copied iris key number at the temporary memory(210) in a case that an iris code of an iris image is identical to the prestored code. The door lock(100) includes a door lock actuator(130), an iris key number database(120) and a controller(110). The controller(110) drives the door lock actuator(130) in a case that an iris code of an iris image is identical to the prestored code.
