Problems solved by technology

[0004] However, in the case of the method (a), since the user is required to input ID and password by key operation, it is necessary for the user to perform cumbersome operations.
On the other hand, in the case of (b), although such an operation is not required, countermeasures against loss of the memory card or forgetting to carry the memory card are required
In addition, both methods may result in the loss of user identification information or impersonation caused by borrowing
[0005] In addition, when multiple users send printing instructions to one MFP, printed matter may be delivered to other users by mistake.

Deformed example 1

[0114] In the above description, the device to be controlled by the control device 20 has been described as the multifunction peripheral 1 . However, as described above, the control target device is not limited to the multifunction peripheral 1, and may be an image output device such as a printer.

[0115] FIG. 13 shows an image output device 1 a including the above-mentioned control device 20 . Even such an image output device (image forming device) 1 a does not require troublesome operations, and can perform user authentication to prevent impersonation with a simple method, while preventing printed matter from being mistakenly seen by other users.

Deformed example 2

[0117] In addition, in the above description, the case where the control device 20 includes the print job storage unit 21 has been described, but the print job storage unit 21 may be located outside the control device 20 . In addition, the print job storage unit 21 and the management unit 15 may be collectively configured as one memory.

Deformed example 3

[0119] Furthermore, in the above description, the configuration in which the control device 20 includes the movement determination unit 23 is employed. As a result, the user authentication process based on the face image is started at the stage where the user's movement to the multifunction peripheral 1 can be detected. As a result, since the user arrives at the multifunction peripheral 1, user authentication processing can be started. Furthermore, when the setting flag is "OFF", the printing process can be started at an earlier stage.

[0120] However, a configuration not including the movement determination unit 23 is also possible. In this case, the face recognition processing unit 25 may start processing when the face position detection unit 22 detects a partial image estimated to be a human face or when the size of the partial image becomes equal to or larger than a predetermined threshold. Alternatively, the face position detection unit 22 and the face recognition proc...

Abstract

A control device of the present invention includes: a face position detecting section for detecting a position of a user's face in an image captured by a capturing device; a face recognition processing section for checking a partial image against reference face images, the partial image being at the position detected in the captured image, and extracting a reference face image that matches the face in the partial image; a user authentication section for specifying a user name that corresponds to the extracted reference face image; and a data checking section for (i) checking whether or not a multifunction printer receives print data added with the specified user name, and (ii) if it is confirmed that the multifunction printer receives the print data, operating an image forming section of the multifunction printer to form an image based on the print data. This realizes a control device which (i) authenticates a user in an easy way in which impersonation can be prevented without inconvenient operation, and (ii) prevents another user from accidentally viewing a printed matter.

Description

technical field [0001] The present invention relates to a control device for performing user authentication processing suitable for an image forming apparatus. Background technique [0002] In recent years, in multifunction peripherals that have functions such as printers, copiers, and scanners, techniques for displaying an operation screen for each user or restricting the use of functions for each user are known. In such a multifunction peripheral, user authentication processing is performed. [0003] In recent years, as user authentication methods in multifunction peripherals, (a) a method in which the user enters an ID (user identification information) and a password for comparison, and (b) a method in which the user non-contactly reads the user identification information from a memory card carried by the user A comparative method (see Patent Document 1 below). [0004] However, in the case of the method (a), since the user is required to input the ID and the password b...
