In access authentication according to the present invention, an input personal identification number(PIN) code is encrypted. Identification information to identify a computer that has generated an encrypted PIN code is associated with the encrypted PIN code, 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 stored in the recording medium. If the identification information is stored in the recording medium, the encrypted PIN code associated with the identification information is decrypted. These processes can be performed on both computer side and recording medium side. |
