Changing of setting of a predetermined function or file that is selected is controlled only by performing fingerprint authentication while data regarding the predetermined function or file is displayed on a display unit. While data regarding a function arbitrarily selected by an input unit from a plurality of functions is displayed on the display unit, a control unit authenticates a user based on fingerprint information representing a fingerprint pattern read by a fingerprint sensor and registered fingerprint information pre-stored in a fingerprint information area. If the authentication is successful, the control unit changes a "user restriction flag" associated with the function selected by the input unit in protection setting information stored in a user restriction flag storage area to an effective state or an ineffective state.
