(Operation example of embodiment)
5 and 6 are flowcharts showing the flow of processing performed by the image forming apparatus 10. An operation example when the image forming apparatus 10 performs face authentication on the user will be described with reference to FIGS.
First, an operation example when the user is correctly authenticated will be described. When the user is not logged in, the control unit 11 displays a screen (FIG. 7) for selecting one of the authentication method using the face image and the authentication method using the user ID and password. The display unit 14 is controlled. In the screen of FIG. 7, for example, when the user C performs an operation of selecting face authentication as an authentication method, the control unit 11 and the imaging unit 18 so that an image captured by the imaging unit 18 is displayed on the display unit 14. The display unit 14 is controlled (step SA1). FIG. 8 is a diagram illustrating an example of a screen displayed on the display unit 14 after the user selects face authentication as the authentication method. The user C looks at the display unit 14 and moves his / her body so that the face is displayed in the frame.
The control unit 11 analyzes the image data generated by the photographing unit 18 and acquires the feature amount of the photographed face (step SA2). Next, the control unit 11 acquires first image data stored in the first storage area 131, that is, image data of a user's face permitted to use the image forming apparatus 10, and the first image data is The feature amount of the face to be shown is acquired (step SA3). The control unit 11 compares the feature quantity acquired in step SA2 with the feature quantity acquired in step SA3, and determines whether there is first image data whose difference between the feature quantity acquired in step SA2 is less than a threshold value. (Step SA4).
When there is first image data whose feature amount difference is less than the threshold value with respect to the feature amount acquired in step SA2 (YES in step SA4), the control unit 11 determines that the feature amount difference is the threshold value in the authentication table TB1. It is determined whether or not the file name of the second image data is stored by referring to the record storing the file name of the first image data that is less than (step SA5). When the file name of the second image data is not stored in the referenced record (NO in step SA5), the control unit 11 does not authenticate a person different from the user C as the user C in the past. The user C is permitted to use the image forming apparatus 10 (step SA6). As a result, the user C is logged in to the image forming apparatus 10.
In addition, the control unit 11 acquires the user name associated with the file name of the first image data whose difference in the acquired feature value is less than the threshold value from the authentication table TB1, and the “user” of the acquired user name The display unit 14 is controlled so that “C” and a message notifying that use has been permitted are displayed (step SA7).
User C confirms the displayed user name and confirms whether he / she has been authenticated. User C confirming that he / she has been authenticated operates the operation unit 12 and uses the image forming apparatus 10. The image forming apparatus 10 records a log of processing executed in response to a user operation. When the user C finishes using the image forming apparatus 10, the user C performs a logout operation on the operation unit 12.
When the user C performs a logout operation, the control unit 11 refers to the recorded log and determines whether a predetermined operation has been performed after the user C logs in and logs out. In the present embodiment, the predetermined operation is an operation other than an operation for logging out. The predetermined operation may be a specific operation such as an operation for instructing execution of copy processing, an operation for instructing execution of scanning processing, or an operation instructing execution of facsimile communication.
If the control unit 11 performs a predetermined operation between the time when the user C logs in and the time when the user C logs out (YES in step SB1), the first image data stored in the first storage area 131 is displayed. Among them, the first image data indicating the face of the user C is updated with the image data generated by the photographing unit 18 (step SB2). Specifically, the control unit 11 writes the image data of the face of the user C generated by the photographing unit 18 in the first storage area 131. In addition, the control unit 11 stores the file name of the image data written in the first storage area 131 in the first image data name field of the logged-out user C record in the authentication table TB1. Further, the control unit 11 erases the first image data having the file name written before updating the first image data name field from the first storage area 131.
As described above, when the user is correctly authenticated, the face image data for authenticating the user is updated with the face image data captured at the time of authentication.
Next, an operation example when the user cannot be correctly authenticated will be described. For example, when user B selects face authentication as the authentication method, the processing from step SA1 to step SA4 is performed in the same manner as when user C is authenticated. Here, for example, the difference between the facial feature amount indicated by the first image data of the user A and the captured facial feature amount of the user B is less than the threshold even though the face of the user B is photographed. In this case, YES is determined in step SA4. If the control unit 11 determines YES in step SA4, the record storing the file name of the first image data in which the difference in the feature amount is less than the threshold in the authentication table TB1, that is, the record of the user A here To determine whether the file name of the second image data is stored (step SA5).
When the file name of the second image data is not stored in the referenced record (NO in step SA5), the control unit 11 does not authenticate a person different from the user A as the user A in the past. Then, use of the image forming apparatus 10 is permitted (step SA6). Accordingly, the person who is performing the operation is the user B, but the user A is logged in to the image forming apparatus 10.
Next, the control unit 11 selects the user name associated with the file name of the first image data in which the difference between the acquired feature values is less than the threshold, that is, the user name of the user A here, the authentication table TB1. The display unit 14 is controlled so that the acquired user name and the message notifying that the use has been permitted are displayed (step SA7).
The user B who has viewed the display unit 14 performs a logout operation on the operation unit 12 without using the various functions of the image forming apparatus 10 because the displayed user name is not his own user name. When the user performs a logout operation, the control unit 11 refers to the recorded log and determines whether a predetermined operation has been performed before the logged-in user logs out.
The control unit 11 authenticates the file name of the image data generated by the photographing unit 18 when a predetermined operation has not been performed between the user logging in and logging out (NO in step SB1). It is stored in the field of “second image data name” in the record of user A in the table TB1 (step SB3), and the image data generated by the photographing unit 18 is written as second image data in the second storage area 132 (step SB4). .
Next, an operation example when the user B who is erroneously authenticated as the user A as described above tries to log in again will be described. When user B selects face authentication as the authentication method, the processing from step SA1 to step SA4 is performed. Here, even when the face of the user B is photographed, the difference between the face feature amount indicated by the first image data of the user A again and the feature amount of the photographed user B face is less than the threshold value. In step SA4, YES is determined.
If the control unit 11 determines YES in step SA4, the record storing the file name of the first image data in which the difference in the feature amount is less than the threshold in the authentication table TB1, that is, the record of the user A here To determine whether the file name of the second image data is stored (step SA5). Here, the file name of the second image data (image data of the face of user B taken in the above operation example) written in the second storage area 132 by the above-described operation is stored in the user A record. (YES in step SA5), the control unit 11 moves the process flow to step SA8.
In step SA8, the controller 11 stores the second image data having the file name stored in the second image data name field of the record of the user A in the authentication table TB1, that is, the second storage area by the above-described operation. The image data of the face of the user B written in 132 is acquired, and the difference between the feature value of the face in the acquired second image data and the feature value of the face of the user B photographed by the photographing unit 18 is less than the threshold value. Judge if there is.
Here, when the difference between the feature amounts is less than the threshold value (YES at step SA8), the control unit 11 determines that the difference between the feature amount of the face of user B acquired at step SA2 at step SA4 is less than the threshold value. In the first image data excluding the first image data of A, it is determined whether there is first image data whose difference from the feature amount of the face of the user B acquired in step SA2 is less than a threshold (step SA9).
Here, the first image data excluding the first image data of the user A includes the first image data of the user B. The facial feature amount indicated by the first image data of the user B is acquired in step SA2. When the difference from the feature amount is less than the threshold, the control unit 11 moves the process flow to step SA5. The control unit 11 refers to the record in which the file name of the first image data of the user B is stored in the authentication table TB1, and determines whether the file name of the second image data is stored (Step SA5). When the file name of the second image data is not stored in the referenced record (NO in step SA5), the control unit 11 permits the user B to use the image forming apparatus 10 (step SA6). As a result, the user B is logged in to the image forming apparatus 10.
The control unit 11 obtains the user name associated with the file name of the first image data in which the difference of the acquired feature value is less than the threshold value from the feature value acquired in step SA2 from the authentication table TB1. The display unit 14 is controlled so that “user B” of the acquired user name and a message notifying that use has been permitted are displayed (step SA7).
User B confirms the displayed user name and confirms whether he / she has been authenticated. User B confirming that he / she has been authenticated operates the operation unit 12 and uses the image forming apparatus 10. The image forming apparatus 10 records a log of processing executed in response to a user operation. When the user B ends the use of the image forming apparatus 10, the user B performs a logout operation on the operation unit 12.
When the user B performs a logout operation, the control unit 11 refers to the recorded log, and determines whether a predetermined operation has been performed after the user B logs out. When a predetermined operation is performed between the time when user B logs in and the time when user B logs out (YES in step SB1), the control unit 11 stores the user B stored in the first storage area 131. The first image data of the face is updated with the image data generated by the photographing unit 18 (step SB2). Specifically, the control unit 11 writes the face image data captured by the imaging unit 18 in the first storage area 131. Further, the control unit 11 stores the file name of the image data written in the first storage area 131 in the first image data name field of the logged-out user B record in the authentication table TB1. In addition, the control unit 11 deletes the image data having the file name written in the user B record before updating the first image data name field from the first storage area 131.
Note that if the control unit 11 determines NO in step SA4 or step SA9, the control unit 11 controls the display unit 14 to display a message notifying that the authentication has failed (step SA10). Further, when the control unit 11 determines NO in step SA8, the control unit 11 moves the process flow to step SA6.
As described above, according to the present embodiment, when a user who has attempted to log in is erroneously authenticated as another user, facial image data when the user is erroneously authenticated is stored. When a user who is mistakenly authenticated attempts to log in next time, the stored image data is used so that the user is not authenticated as another user.
In the embodiment described above, the face image data for authenticating the user is stored in the storage unit 13, but is not limited to this configuration. For example, the server apparatus storing the authentication table TB1 and the face image data is connected to the image forming apparatus 10 via the communication line, and the image data generated by the photographing unit 18 is transmitted to the server apparatus, and the server apparatus authenticates. Processing may be performed. In addition, when the server apparatus authenticates the user, the server apparatus may control the image forming apparatus 10 so that the user can use the image forming apparatus 10. In this configuration, log data may be stored in the image forming apparatus 10 or log data may be stored in the server apparatus.
In the above-described embodiment, the first image data is stored in the first storage area 131 and the second image data is stored in the second storage area 132. However, the present invention is not limited to this configuration. For example, instead of the first image data, feature amount data indicating the feature amount of the face of the user who is permitted to use the image forming apparatus 10 is stored in the first storage area 131, and is replaced with the second image data. The feature amount data indicating the feature amount of the face photographed by the unit 18 may be stored in the second storage area 132. In this configuration, the feature quantity of the face photographed by the photographing unit 18 is compared with the feature quantity data indicated by the feature quantity data stored in the storage unit 13 to authenticate the user. According to this configuration, the feature amount is acquired from the face image data stored in the storage unit 13 and compared with the configuration in which the feature amount is compared with the captured face feature amount, the face image data is obtained each time authentication is performed. Since it is not necessary to acquire the facial feature amount, the authentication process can be performed quickly.
The information processing apparatus of the present invention may be an information processing apparatus other than an image forming apparatus having a plurality of functions, for example, an information processing apparatus such as a scanning device, a copying machine, or a facsimile device, or a personal computer Or an information processing apparatus such as a server apparatus. Each function realized by the control unit 11 of the image forming apparatus 10 according to the above-described embodiment or modification may be realized by one or a plurality of hardware circuits, and the arithmetic device executes one or a plurality of programs. Or may be realized by a combination thereof. When the function of the control unit 11 is realized using a program, the program includes a magnetic recording medium (magnetic tape, magnetic disk (HDD (Hard Disk Drive), FD (Flexible Disk)), etc.), optical recording medium (optical disk). Etc.), may be provided in a state of being stored in a computer-readable recording medium such as a magneto-optical recording medium or a semiconductor memory, or may be distributed via a communication line.
