Patent ID: 7315232

Claim:
A use management method for a processing apparatus, said processing apparatus arranged for authenticating through collating an input of identification code with an identification code stored in advance, reading biometrics information from an entry process made when the authentication has been admitted and storing the biometrics information in a first storage area of a storage unit, collating biometrics information read from the succeeding entry process with the biometrics information stored in the first storage area, conducting a process based on the entry process with the authenticated identification code when the collation result is conformity, and erasing the biometrics information stored in the first storage area of the storage unit when the collation result is disconformity, the method comprising the steps of: evacuating the biometrics information stored in the first storage area before erased to the second storage area of the storage unit when an entry process is made with biometrics information which is different from the biometrics information stored in the first storage area of the storage unit; and restoring the biometrics information in the second storage area to the first storage area of the storage unit when an entry process is made with the biometrics information having been evacuated.
