Patent attributes
In an image processing apparatus is arranged for authenticating through collating an input of identification code with an identification code stored in advance, reading the biometrics information from an entry process made when the authentication has been admitted and storing the biometrics information in the 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 when the collation result is disconformity, when an entry process is made with biometrics information which is different from the biometrics information stored in the first storage area, the biometrics information stored in the first storage area before erased is evacuated to the second storage area.
