PROBLEM TO BE SOLVED: To improve the accuracy of user authentication at an information processing device that authenticates a user by a photographic image such as face authentication.SOLUTION: An image formation device 101 comprises a radio communication unit 411, a radio authentication unit 412, an imaging unit 414, an image authentication unit 415, an image determination unit 418, and a device authentication unit 419. The radio communication unit 411 obtains prescribed information from a radio tag. The radio authentication unit 412 authenticates a radio tag on the basis of the obtained prescribed information. The imaging unit 414 takes an image of a user. The image authentication unit 415 authenticates a user on the image. The image determination unit 418 determines whether a determination object on the image is a living body meeting prescribed conditions. The device authentication unit 419 permits the user to use the image formation device if it is determined that the determination object on the image is a living body meeting the prescribed conditions, and the user of the radio tag authenticated by the radio authentication unit is the same as the user authenticated by the image authentication unit.SELECTED DRAWING: Figure 19 |
