METHOD FOR CERFICATING INDIVIDUAL, IRIS REGISTERING DEVICE, SYSTEM FOR CERTIFICATING IRIS, AND PROGRAM FOR CERFICATING INDIVIDUAL |
摘要 |
A plurality of iris codes are registered for each registrant in an iris database (12) together with pupil diameter-iris diameter ratio R. At the time of authentication, an iris code is obtained from a captured iris image by feature extraction while pupil diameter-iris diameter ratio R is obtained. Ratio R obtained at the time of registration and ratio R obtained at the time of authentication are compared to specify an appropriate iris code from the iris database (12) as an item to be collated before authentication. <IMAGE> |
