Abstract
In a system (e.g., debit card) where a PIN is entered as verification, the PIN and biometric information, which is free of being stolen or faked, are combined to realize secure user verification. The leakage and the theft of a PIN is reliably prevented, thereby realizing a high security ability. To-be-verified biometric feature data is transmitted from first transceiving interface (205) of data processing device (200) to portable electronic device (300). Biometric feature data verifying section (306) of portable electronic device (300) compares the to-be-verified biometric feature data, which has been received by second transceiving interface (301), with valid biometric feature data. If a predetermined matching condition between the to-be-verified biometric feature data and the valid biometric feature data is satisfied, a PIN stored in portable electronic device (300) is transmitted from second transceiving interface (301) to management device (400) via first transceiving interface (205) of data processing device (200).
