IRIS KEY SYSTEM FOR DATA SECURITY OF DATA STORAGE, AND ITS SECURITY METHOD

摘要

PURPOSE: An iris key system and its security method are provided to enable a user to use data at a storage after a user's iris is identified and checked so that it prevents an illegal data leakage. CONSTITUTION: The system comprises an iris key system(200) and a data storage(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 data storage(100) includes a data storage(130), an iris key number database(120) and a storage controller(110). The storage controller(110) allows the user to use the data storage(130) in a case that an iris code of an iris image is identical to the prestored code.
