Abstract
An input personal identification number (PIN) is encrypted, identification information to identify a computer that has generated an encrypted PIN is associated with the encrypted PIN, and the associated information is sent to a recording medium. When the recording medium is again connected to the computer, it is checked whether the identification information is present in the recording medium. If the identification information is present in the recording medium, the encrypted PIN associated with the identification information is decrypted. These processes can be performed on both computer side and recording medium side.
