A device needs to be created which can register biometric information by using an automated machine such as ATM and which can also verify an identity of a user. In this invention, a storage medium, which stores a decryption key and a decryption program for executing decryption processing using the decryption key, and an encryption key corresponding to the decryption key are sent to the user through separate routes. Biometric information of the user entered into the terminal device/ATM is encrypted with the encryption key that the user enters into the terminal device/ATM. The encrypted biometric information is sent to the IC card, and the storage medium decrypts the encrypted biometric information with the decryption key stored therein and stores the decrypted biometric information in itself.
