Abstract: To provide a technique that can prevent a situation in which a third person other than a pre-registered user illegally succeeds in authentication.SOLUTION: A control unit, when it should authenticate for the execution of a specific function, causes a display unit to display both of a face image of a specific user captured by a first imaging unit that images the face of the user and a code image generated by a second imaging unit that images an information code. While both of the face image and the code image are displayed on the display unit, the control unit executes a first type determination as to whether specific face data extracted based on the face image corresponds to registered face data stored in a memory and also executes a second type determination as to whether output of data recorded in the information code based on the code image is successful. When a situation is established in which the determination is affirmative in both the first type determination and the second type determination while the face image and the code image are displayed on the display unit, the control unit determines that the authentication was successful and permits the execution of the specific function.SELECTED DRAWING: Figure 3
