ABSTRACT:
A mobile terminal device includes biometric information detecting means for detecting biometric information; encryption key generating means for generating an encryption key on the basis of the biometric information in registration; encrypting means for encrypting a predetermined personal identification number with the encryption key to generate a biometric encrypted personal identification number in the registration; encrypted personal-identification-number storing means for storing the biometric encrypted personal identification number in the registration; decryption key generating means for generating a decryption key on the basis of the detected biometric information in verification; decrypting means for decrypting the biometric encrypted personal identification number with the decryption key to reproduce the personal identification number in the verification; and personal identification number verifying means for comparing the reproduced personal identification number with the stored biometric encrypted personal identification number to perform the personal-identification-number verification.
