Abstract
Each of the authentication apparatus and the authentication target device holds the last piece of authentication information subjected to an authentication process. When the authentication target device is reconnected to the authentication apparatus, the authentication apparatus collates the authentication information held in the authentication apparatus with the authentication information read out of the authentication target device. The authentication apparatus determines, based on the collation result, whether or not the authentication target device has been authenticated by a different authentication apparatus.
