[0002] In facilities where authentication is required at the time of entry and exit, a gate device installed at the entrance authenticates those who wish to enter and exit, and controls the opening and closing of the gate depending on the authentication result. In recent years, there has been a demand for a gateless walk-through type authentication system in order to authenticate a large number of people simultaneously.

[0003] Patent Document 1 discloses a technology related to a personal authentication system using a pressure sensor. In the personal authentication system according to Patent Document 1, when a person walks on a sensor sheet on which a large number of pressure sensors are arranged, an information processing device determines whether the pressure information indicates a person who has been registered in advance based on the pressure information detected by the sensor sheet, and issues a warning if the person is not registered.

[0004] Patent Document 2 discloses technology relating to a person authentication device that determines whether a pedestrian is a person registered in advance by comparing a facial image captured of a pedestrian walking in a specified area with pre-registered dictionary information.

[0014] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In each drawing, the same or corresponding elements are denoted by the same reference numerals, and duplicated descriptions will be omitted as necessary for clarity of explanation.

[0015] <Embodiment 1> Fig. 1 is a block diagram showing the configuration of an authentication control device 10 according to the first embodiment. The authentication control device 10 is an information processing device that performs personal authentication of a person photographed by an image capture device (not shown) when entering or leaving a facility or the like, and displays information about the authentication result on a light-emitting element (not shown) embedded in the floor. Here, the authentication control device 10 is connected to a network (not shown). The network may be wired or wireless. The network is also connected to an image capture device installed in a passageway of the facility and a light-emitting element embedded in the passageway.

[0016] The authentication control device 10 includes a biometric information acquisition unit 11, an authentication control unit 12, a position identification unit 13, and a display control unit 14. The biometric information acquisition unit 11 acquires biometric information of a pedestrian on a specific passage from an image captured by a photographing device of the pedestrian. Here, it is assumed that a plurality of light-emitting elements are embedded in the passage. Furthermore, it is assumed that the light emission of each light-emitting element can be controlled by the authentication control device 10. Furthermore, the biometric information includes facial feature information, iris information, and the like.

[0017] The authentication control unit 12 obtains a biometric authentication result between the obtained biometric information and the biometric information of multiple people. When the biometric information of multiple people is stored in advance in the authentication control device 10, the authentication control unit 12 performs an authentication process. When the facial feature information of multiple people is stored in advance in an authentication device external to the authentication control device 10, the authentication control unit 12 causes the authentication device to perform authentication and obtains the authentication result.

[0018] The position identifying unit 13 identifies the position of a pedestrian on the passage by analyzing the captured image. The display control unit 14 controls the display of the biometric authentication result on the light emitting element corresponding to the light emitting target area including the identified position.

[0019] 2 is a flowchart showing a flow of the authentication control method according to the embodiment 1. As a premise, a photographing device installed in the passage captures an image of a pedestrian on the passage, and the authentication control device 10 acquires the captured image. Then, the biometric information acquiring unit 11 acquires biometric information of the pedestrian from the captured image (S11).

[0020] Next, the authentication control unit 12 obtains a biometric authentication result between the biometric information obtained in step S11 and the biometric information of multiple people (S12). Then, the position identification unit 13 analyzes the captured image to identify the position of the pedestrian on the passage (S13). After that, the display control unit 14 performs display control regarding the biometric authentication result obtained in step S12 on the light-emitting element corresponding to the light-emitting target area including the position identified in step S13 (S14).

[0021] In this way, according to the present embodiment, the biometric authentication result of a pedestrian can be displayed near the feet of the pedestrian, and therefore the biometric authentication result of an authentication target can be appropriately notified in a walk-through type authentication system.

[0022] The authentication control device 10 includes a processor, a memory, and a storage device, which are not shown in the figure. The storage device stores a computer program that implements the processing of the image providing method according to this embodiment. The processor then loads the computer program from the storage device into the memory and executes the computer program. In this way, the processor realizes the functions of a biometric information acquisition unit 11, an authentication control unit 12, a position identification unit 13, and a display control unit 14.

[0023] Alternatively, the biometric information acquisition unit 11, the authentication control unit 12, the position identification unit 13, and the display control unit 14 may each be realized by dedicated hardware. Also, a part or all of the components of each device may be realized by a general-purpose or dedicated circuit, processor, or a combination of these. These may be configured by a single chip, or may be configured by multiple chips connected via a bus. A part or all of the components of each device may be realized by a combination of the above-mentioned circuits, etc., and a program. Also, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an FPGA (field-programmable gate array), etc. may be used as the processor.

[0024] Furthermore, when some or all of the components of the authentication control device 10 are realized by multiple information processing devices, circuits, etc., the multiple information processing devices, circuits, etc. may be centrally or distributed. For example, the information processing devices, circuits, etc. may be realized as a client-server system, cloud computing system, etc., in which each is connected via a communication network. Furthermore, the functions of the authentication control device 10 may be provided in a SaaS (Software as a Service) format.

[0025] <Embodiment 2> The second embodiment is a specific example of the first embodiment. Fig. 3 is a block diagram showing the overall configuration of an authentication control system 1000 according to the second embodiment. The authentication control system 1000 is an information system that displays the biometric authentication results for each of a plurality of pedestrians U1 to U3 walking along a passage 400 on light-emitting elements near the feet of each pedestrian. In the following description, the biometric authentication is assumed to be face authentication, and the biometric information is assumed to be face feature information, but other technologies that use captured images can be applied to the biometric authentication and the biometric information.

[0026] The authentication control system 1000 includes an authentication device 100, an authentication control device 200, cameras 310-340, and light-emitting elements 411-414. The authentication device 100, the authentication control device 200, the cameras 310-340, and the light-emitting elements 411-414 are each connected via a network N. Here, the network N is a wired or wireless communication line.

[0027] The passage 400 has four cameras 310-340 installed at the entrances and a plurality of light emitting elements 411-414 buried under the floor. In particular, the light emitting elements 411-414 are arranged at a predetermined interval under the floor in a predetermined section of the passage 400, and are arranged so as to generally correspond to the positions of pedestrians. Each of the cameras 310-340 photographs a predetermined area of ​​the passage 400 from a respective angle, and transmits the photographed image to the authentication control device 200 via the network N. Note that at least one camera 310 etc. is sufficient. The camera 310 etc. may also be a stereo camera capable of measuring distances. The light emitting elements 411-414 are light emitting diodes, for example, LEDs (Light Emitting Diodes). There are two or more light emitting elements 411 etc., but preferably, the passage 400 is filled in a checkerboard pattern. The light emitting elements 411 etc. receive a control signal from the authentication control device 200 via the network N, and emit light in a color or light emitting pattern according to the control signal. The light emitting elements 411 and the like may be controlled so that a plurality of adjacent light emitting elements are treated as one unit.

[0028] The authentication device 100 is an information processing device that stores facial feature information of multiple people. In response to a facial authentication request received from the outside, the authentication device 100 compares the facial image or facial feature information included in the request with the facial feature information of each user, and returns the comparison result (authentication result) to the request source.

[0029] FIG. 4 is a block diagram showing a configuration of an authentication device 100 according to the second embodiment. The authentication device 100 includes a face information DB (DataBase) 110, a face detection unit 120, a feature point extraction unit 130, a registration unit 140, and an authentication unit 150. The face information DB 110 stores a user ID 111 and face feature information 112 of the user ID in association with each other. The face feature information 112 is a set of feature points extracted from a face image. The authentication device 100 may delete the face feature information 112 in the face feature DB 110 in response to a request from a registered user of the face feature information 112. Alternatively, the authentication device 100 may delete the face feature information 112 after a certain period of time has elapsed since the registration of the face feature information 112.

[0030] The face detection unit 120 detects a face area included in a registration image for registering face information, and outputs the face area to the feature point extraction unit 130. The feature point extraction unit 130 extracts feature points from the face area detected by the face detection unit 120, and outputs face feature information to the registration unit 140. The feature point extraction unit 130 also extracts feature points included in a face image received from the authentication control device 200, and outputs the face feature information to the authentication unit 150.

[0031] The registration unit 140 issues a new user ID 111 when registering the facial feature information. The registration unit 140 associates the issued user ID 111 with the facial feature information 112 extracted from the registered image and registers them in the facial information DB 110. The authentication unit 150 performs face authentication using the facial feature information 112. Specifically, the authentication unit 150 compares the facial feature information extracted from the face image with the facial feature information 112 in the facial information DB 110. The authentication unit 150 returns a match of the facial feature information to the authentication control device 200. The match of the facial feature information corresponds to the success or failure of authentication. The match of the facial feature information (match) refers to a case where the degree of match is equal to or greater than a predetermined value.

[0032] 5 is a flowchart showing the flow of face information registration processing according to the present embodiment 2. Here, an information registration terminal (not shown) photographs the body including the face of each user, and transmits a face information registration request including the photographed image (registration image) to the authentication device 100 via the network N. The information registration terminal is, for example, an information processing device such as a personal computer, a smartphone, or a tablet terminal.

[0033] First, the authentication device 100 acquires a registration image included in a face information registration request (S21). For example, the authentication device 100 accepts a face information registration request from an information registration terminal via a network N. Next, the face detection unit 120 detects a face area included in the registration image (S22). Next, the feature point extraction unit 130 extracts feature points from the face area detected in step S22, and outputs face feature information to the registration unit 140 (S23). Finally, the registration unit 140 issues a user ID 111, associates the user ID 111 with face feature information 112, and registers the user ID 111 and face feature information 112 in the face information DB 110 (S24). Note that the authentication device 100 may receive the face feature information 112 from the information registration terminal, and register the face feature information 112 in the face information DB 110 in association with the user ID 111.

[0034] FIG. 6 is a flowchart showing the flow of face authentication processing by the authentication device 100 according to the second embodiment. First, the feature point extraction unit 130 acquires a face image for authentication included in a face authentication request (S31). For example, the authentication device 100 receives a face authentication request from the authentication control device 200 via the network N, and extracts face feature information from the face image included in the face authentication request as in steps S21 to S23. Alternatively, the authentication device 100 may receive face feature information from the authentication control device 200. Next, the authentication unit 150 compares the acquired face feature information with the face feature information 112 in the face information DB 110 (S32). If the face feature information matches, that is, if the degree of match of the face feature information is equal to or greater than a predetermined value (Yes in S33), the authentication unit 150 identifies the user ID 111 of the user whose face feature information matches (S34), and returns the fact that face authentication was successful and the identified user ID 111 to the authentication control device 200 (S35). If there is no matching facial feature information (No in S33), the authentication unit 150 returns a message to the authentication control device 200 indicating that face authentication has failed (S36).

[0035] In step S32, the authentication unit 150 does not need to attempt matching with all of the facial feature information 112 in the facial information DB 110. For example, the authentication unit 150 may preferentially attempt matching with facial feature information registered during the period from the day the facial authentication request was accepted to several days prior. This can improve the matching speed. Also, if the preferential matching fails, it may be possible to perform matching with all of the remaining facial feature information.

[0036] Returning to Fig. 3, the description will continue. The authentication control device 200 is an information processing device that performs face authentication on pedestrians (users) U1 to U3 included in a captured image received from a camera 310 or the like, and displays the face authentication results on light-emitting elements near the feet of each pedestrian. The authentication control device 200 may be redundantly configured with multiple servers, and each functional block may be realized by multiple computers.

[0037] Next, the authentication control device 200 will be described in detail. FIG. 7 is a block diagram showing the configuration of the authentication control device 200 according to the second embodiment. The authentication control device 200 includes a storage unit 210, a memory 220, a communication unit 230, and a control unit 240. The storage unit 210 is a storage device such as a hard disk or a flash memory. The storage unit 210 stores a program 211 and a maximum number of people who can pass 212. The program 211 is a computer program in which the processing of the authentication control method according to the second embodiment is implemented. The maximum number of people who can pass 212 is the maximum number of pedestrians who can pass through the passage 400. The maximum number of people who can pass 212 is information registered in advance by an administrator or the like.

[0038] The memory 220 is a volatile storage device such as a RAM (Random Access Memory), and is a storage area for temporarily holding information during operation of the control unit 240. The communication unit 230 is a communication interface with the network N.

[0039] The control unit 240 is a processor, that is, a control device, that controls each component of the authentication control device 200. The control unit 240 loads the program 211 from the storage unit 210 into the memory 220, and executes the program 211. In this way, the control unit 240 realizes the functions of an acquisition unit 241, an authentication control unit 242, a position identification unit 243, a determination unit 244, a display control unit 245, a detection unit 246, and a calculation unit 247.

[0040] The acquisition unit 241 is an example of the biometric information acquisition unit 11. The acquisition unit 241 acquires captured images from each of the cameras 310 to 340 via the network N. Then, the acquisition unit 241 extracts (acquires) facial feature information of a person's face area from each captured image as biometric information. Furthermore, the acquisition unit 241 outputs each captured image to the position identification unit 243.

[0041] The authentication control unit 242 is an example of the authentication control unit 12. The authentication control unit 242 controls face authentication for the face regions of each of the walkers U1 to U3 included in the captured image. The authentication control unit 242 causes the authentication device 100 to perform face authentication for each walker based on the face feature information acquired from the captured image, and acquires the face authentication result from the authentication device 100. For example, the authentication control unit 242 transmits a face authentication request including the acquired face feature information to the authentication device 100 via the network N, and receives the face authentication result of each walker from the authentication device 100.

[0042] The position identifying unit 243 is an example of the position identifying unit 13. The position identifying unit 243 identifies the position of a pedestrian on the passage 400 by analyzing the captured image. For example, the position identifying unit 243 may identify position coordinates from the area of ​​each pedestrian in the captured image and convert them into position coordinates on the passage 400. The identified position coordinates can identify at least the light emitting elements 411 to 414, etc. Furthermore, when each of the cameras 310, etc. is a stereo camera, the position identifying unit 243 identifies the position of each pedestrian on the passage 400 by analyzing two captured images.

[0043] The determination unit 244 determines the display mode and the light emission target area based on the face authentication result. That is, at least one of the display mode and the light emission target area differs depending on whether the face authentication result is successful or not. Here, the display mode refers to the way in which the light emitting element emits light, for example, the light emission color, the light emission pattern (blinking pattern), the light emission time, etc. Also, the light emission target area refers to the surrounding area including the position of the pedestrian identified by the position identification unit 243, and corresponds to one or more light emitting elements.

[0044] For example, when the face authentication result indicates authentication failure, the determination unit 244 may determine the light-emitting target area to be wider than when the face authentication result indicates authentication success. That is, when the face authentication result indicates authentication failure, the determination unit 244 may increase the area size. Furthermore, when the face authentication result indicates authentication failure, the determination unit 244 may determine the light-emitting target area including the pedestrian's predicted moving direction from the captured image. For example, when the face authentication is successful, the determination unit 244 may determine the vicinity of the pedestrian's feet as the light-emitting target area, and when the face authentication is unsuccessful, the determination unit 244 may determine a wider area from the pedestrian's feet to the moving direction as the light-emitting target area. Alternatively, when the face authentication is unsuccessful, the determination unit 244 may determine the movement trajectory of the pedestrian as the light-emitting target area.

[0045] The determination unit 244 may determine at least one of different light emitting colors or light emitting patterns as the display mode depending on whether the face authentication result is successful or not. For example, the determination unit 244 may set the light emitting color to blue or green when the face authentication result is successful, and set the light emitting color to red when the face authentication result is unsuccessful. The determination unit 244 may also set the blinking interval of the light emitting pattern to be shorter when the face authentication result is unsuccessful than when the authentication is successful. This makes it easier to recognize the authentication failure.

[0046] In addition, the determination unit 244 may determine the display mode so that the light emission time is longer when the face authentication result indicates authentication failure than when the face authentication result indicates authentication success. For example, the feet of a pedestrian whose face authentication is successful may be illuminated in green for a moment, and the feet of a pedestrian whose face authentication is unsuccessful may be illuminated in red for a while. In addition, the pedestrian's movement trajectory can be displayed by extending the light emission time when authentication is unsuccessful.

[0047] In addition, the determination unit 244 determines the display mode so that when the face authentication result indicates authentication failure, the face authentication result is highlighted more than when the face authentication result indicates authentication success. Here, highlighting includes, for example, but is not limited to, making the brightness higher or increasing the blinking frequency. Also, highlighting may include making the light-emitting target area wider.

[0048] The display control unit 245 is an example of the display control unit 14. The display control unit 245 performs display control according to the determined display mode for the light-emitting element corresponding to the determined target light-emitting region. That is, the display control unit 245 identifies the light-emitting element corresponding to the target light-emitting region, and transmits a control signal based on the display mode to the identified light-emitting element via the network N.

[0049] When the face authentication result indicates authentication failure, the display control unit 245 performs display control to maintain the lighting of the light-emitting element corresponding to the light-emitting target area. When the face authentication result indicates authentication success after authentication failure, the display control unit 245 performs display control to turn off the light-emitting element that maintained the lighting when the authentication failed.

[0050] The detection unit 246 detects the number of pedestrians in the passage 400 from the captured image. The calculation unit 247 calculates the remaining number of people who can pass through from the maximum number of people 212 who can pass through the passage 400 and the detected number of people. Then, the display control unit 245 performs display control so that a predetermined light-emitting element displays the calculated number of people who can pass through. Furthermore, when the detected number of people exceeds the maximum number of people who can pass through 212, the display control unit 245 performs display control so that a warning is displayed on the predetermined light-emitting element. Here, the predetermined light-emitting element may be, for example, a specific light-emitting element buried near the entrance / exit of the passage 400.

[0051] 8 is a flowchart showing the flow of the authentication control method according to the embodiment 2. First, it is assumed that pedestrians U1 to U3 are walking on the passage 400. Then, it is assumed that the cameras 310 to 340 start capturing images and sequentially transmit the captured images to the authentication control device 200 via the network N.

[0052] At this time, the acquisition unit 241 acquires captured images from each of the cameras 310 to 340 via the network N (S401). The following description focuses on the processing of one image. Then, the authentication control unit 242 makes a face authentication request to the authentication device 100 for each pedestrian included in the captured image (S402). Specifically, the acquisition unit 241 extracts the face area of ​​each pedestrian from the captured image and acquires face feature information from the face area. Then, the authentication control unit 242 includes the face feature information for each pedestrian in the face authentication request and transmits it to the authentication device 100 via the network N. Then, the authentication control unit 242 acquires the face authentication result for each pedestrian from the authentication device 100 (S403).

[0053] In parallel with step S401, the position identifying unit 243 identifies the position of the pedestrian by analyzing the captured image (S404). That is, the position identifying unit 243 converts the position coordinates of the pedestrian in the captured image into position coordinates on the passage 400.

[0054] After steps S403 and S404, the determination unit 244 determines a light emission target area including the specified position based on the face authentication result (S405). The determination unit 244 also determines a display mode based on the face authentication result (S406). Note that steps S405 and S406 may be executed in parallel or in series.

[0055] After steps S405 and S406, the display control unit 245 performs display control according to the display mode for the light emitting element corresponding to the light emission target area (S407). FIG. 9 is a diagram showing an example of display control according to the second embodiment. Here, it is assumed that the pedestrians U1 and U2 move toward the back of the passage 400, and the pedestrian U3 moves toward the front. It is also assumed that the face authentication of the pedestrians U1 and U3 is successful, and the face authentication of the pedestrian U2 is unsuccessful. Therefore, it is shown that the determination unit 244 has determined the light emission target area (display 402) of the pedestrian U2 to be wider than the light emission target areas (displays 401 and 403) of the pedestrians U1 and U3. The displays 401 and 403 have the vicinity of the feet of the pedestrians U1 and U3 as the lighting area. The determination unit 244 may determine the displays 401 and 403 so that the pedestrians U1 and U3 follow their movements. The display 402 may be an example of lighting the movement trajectory of the pedestrian U2. Also, the determination unit 244 indicates that it has determined that the display mode (display 402) of the pedestrian U2 is to be displayed more highlighted than the display modes (displays 401 and 403) of the pedestrians U1 and U3.

[0056] FIG. 10 is a diagram showing another example of display control according to the second embodiment. Here, a case is shown in which the travel direction of the pedestrian is set as the light-emitting target area when the authentication fails. It is assumed that the pedestrian U2 is moving toward the back of the passage 400, and the face authentication has failed. At this time, the determination unit 244 analyzes the captured images from the latest captured image to several frames before, identifies the displacement of the area corresponding to the pedestrian U2, and predicts the travel direction. Then, the determination unit 244 determines the light-emitting target area including the travel direction of the pedestrian U2. The display 402a is an example in which the travel direction side of the pedestrian U2 is set as the light-emitting target area. This allows the pedestrian U2 to more directly recognize that the face authentication has failed, and can promote face authentication by, for example, turning his / her face toward the camera.

[0057] Fig. 11 is a flowchart showing the flow of the passer-by number monitoring process according to the second embodiment. The passer-by number monitoring process is executed in parallel with the above-mentioned authentication control process. Specifically, step S401 is the same as in Fig. 8. Thereafter, step S410 and subsequent steps are executed in parallel with steps S402 and S404. That is, the detection unit 246 detects the number of pedestrians in the passage 400 from the captured image (S410). For example, the detection unit 246 analyzes the captured image and counts the number of areas corresponding to pedestrians.

[0058] Next, the display control unit 245 judges whether the detected number of people is equal to or less than the maximum number of people that can pass 212 (S411). If the result in step S411 is YES, that is, if the detected number of people is equal to or less than the maximum number of people that can pass 212, the calculation unit 247 calculates the remaining number of people that can pass from the maximum number of people that can pass 212 and the detected number of people (S412). Then, the display control unit 245 performs display control so as to display the calculated remaining number of people that can pass on a predetermined light-emitting element (S413).

[0059] On the other hand, if step S411 is NO, that is, if the detected number of people exceeds the maximum number of people that can pass 212, the display control unit 245 performs display control to display a warning on a predetermined light-emitting element (S414). The warning display may be, for example, light-emitting elements embedded in rows on both ends of the passage 400 that light up areas where pedestrians do not walk, such as by lighting up red. This makes it easier to keep pedestrians entering the passage 400 within a range where authentication can be performed by the authentication control device 200. This allows the authentication control system 1000 to operate stably.

[0060] Here, in this embodiment, when the face authentication result indicates authentication failure, the movement trajectory of the pedestrian may be displayed on the passage 400. As an example, when the face authentication result indicates authentication failure, the display control unit 245 performs display control to maintain the lighting of the light-emitting element corresponding to the light-emitting target area. For example, the display 402 in FIG. 9 shows a state in which the pedestrian U2 has failed face authentication several times in succession. Therefore, the pedestrian U2 can more appropriately recognize that he or she has failed face authentication. In addition, it becomes easier for the surrounding security guards to more appropriately recognize that the pedestrian U2 has failed face authentication, and to call out to the pedestrian U2.

[0061] Then, it is assumed that the pedestrian U2 has succeeded in face authentication after that. In other words, when the face authentication result indicates success after authentication failure, the display control unit 245 performs display control to turn off the light-emitting elements that remained on when the authentication failed. This allows the pedestrian U2 to more appropriately acknowledge that he or she has succeeded in face authentication. The same applies to security guards, etc.

[0062] The display of the movement trajectory may be realized as follows. First, the authentication control device 200 further includes a storage unit that extracts a body shape feature of the pedestrian from a captured image, and stores the extracted body shape feature and the identified position in association with each other in the history storage unit. Then, when the biometric authentication result indicates an authentication failure, the determination unit acquires a position associated with the body shape feature of the pedestrian who has failed to be authenticated from the history storage unit, generates a movement trajectory of the pedestrian using the acquired position, and determines the movement trajectory as the light-emitting target area. After that, the display control unit performs display control on the light-emitting element corresponding to the determined movement trajectory. This makes it possible to display the movement trajectory of the pedestrian who has walked from the start of authentication to the determination of the authentication result at the timing when the authentication result is determined.

[0063] The display mode may be changed according to the success or failure of the authentication result as follows. First, the display control unit 245 performs display control so that the light-emitting element corresponding to the light-emitting target area is turned on in the first direction from after the position is specified until the biometric authentication result of the pedestrian is acquired. The first lighting is, for example, yellow. Next, after the biometric authentication result is acquired, the display control unit 245 selects either the second lighting or the third lighting according to the success or failure of the biometric authentication result. For example, the second lighting is blue when the face authentication is successful, and the third lighting is red when the face authentication is unsuccessful. Then, the display control unit 245 performs display control so that the light-emitting element corresponding to the light-emitting target area is turned on in the selected direction. The second lighting and the third lighting may be brighter than the first lighting. Alternatively, the light may be turned off instead of the first lighting. In other words, the light may be turned off during authentication, and turned on according to the authentication result when the authentication result is obtained. Even in this manner, the difference in the authentication result can be appropriately notified to the pedestrian and the security guard.

[0064] In this embodiment, the display of the success or failure of the authentication result may be differentiated between employees and guests of the facility. In this case, the storage unit 210 is assumed to store in advance the user ID of the employee and the attribute (affiliation) etc. in association with each other. Then, the determination unit 244 identifies the attribute of the walker based on the biometric authentication result. For example, when the biometric authentication result is successful, the determination unit 244 identifies the user ID included in the biometric authentication result and acquires the attribute associated with the identified user ID from the storage unit 210. When the attribute can be acquired, since the person is an employee, the determination unit 244 makes the display mode more modest compared to that of the guest. Alternatively, in the case of an employee, the determination unit 244 makes the light-emitting target area narrower compared to that of the guest. In other words, when the attribute cannot be acquired, since the person is a guest, the determination unit 244 makes the display mode more exaggerated compared to that of the employee. Alternatively, in the case of a guest, the determination unit 244 makes the light-emitting target area wider compared to that of the employee. This can improve the hospitality of the guest.

[0065] <Embodiment 3> The third embodiment is a modified example of the second embodiment. In the third embodiment, a pressure sensor is used in addition to image analysis to identify the position of a pedestrian. FIG. 12 is a block diagram showing the overall configuration of an authentication control system 1000a according to the third embodiment. Compared to the above-mentioned authentication control system 1000, the authentication control system 1000a replaces the authentication control device 200 with an authentication control device 200a, and pressure sensors 421 to 424 are added. The other configurations are the same as those of the authentication control system 1000.

[0066] The pressure sensors 421-424 correspond to the light emitting elements 411-414, respectively, and are buried under the floor of the passage 400a. Each of the pressure sensors 421-424 is connected to a network N. When each of the pressure sensors 421-424 detects a pressure equal to or greater than a certain level when a load is applied by the foot of any of the walkers U1-U3, the pressure sensors 421-424 notify the authentication control device 200a of the detection result via the network N. The detection result includes position information of the pressure sensor.

[0067] The authentication control device 200a is not shown in the diagram because its configuration is the same as that in FIG. 7. However, the authentication control device 200a differs from the authentication control device 200 in the program 211, the acquisition unit 241, and the position identification unit 243. The program 211 stored in the storage unit 210 of the authentication control device 200a is a computer program in which the processing of the authentication control method according to the third embodiment is implemented. The acquisition unit 241 included in the authentication control device 200a further includes a function of a detection result acquisition means for acquiring the detection result by the pressure sensor. The position identification unit 243 included in the authentication control device 200a further takes the detection result into account to identify the position of the pedestrian on the passage 400a.

[0068] Fig. 13 is a flowchart showing the flow of the authentication control method according to the third embodiment. Steps S401 to S403 and S405 to S407 are the same as those in Fig. 8 described above. Independently of step S401, the acquisition unit 241 acquires detection results from each of the pressure sensors 421 to 424 via the network N (S401a). After steps S401 and S401a, the position identification unit 243 identifies the position of the pedestrian by analyzing the captured image and the detection result (S404a). The rest is the same as Fig. 8.

[0069] In this way, in the third embodiment, the detection result of the pressure sensor is used in addition to the image analysis to identify the position of the pedestrian. Therefore, in addition to the same effects as in the second embodiment, the accuracy of identifying the position of the pedestrian is improved compared to the second embodiment.

[0070] <Embodiment 4> The present embodiment 4 is a modified example of the above-mentioned embodiments 2 and 3. In recent years, from the viewpoint of preventing the spread of infectious diseases, the determination of entry eligibility has increasingly been based not only on checking information against pre-registered information but also on checking the health condition of the person at the time of entry. Therefore, in a walk-through type authentication system, in addition to biometric authentication, it is desirable to display information according to the body surface temperature of the pedestrian. Therefore, in the present embodiment 4, in addition to the above-mentioned embodiments 2 and 3, display control is performed according to the body surface temperature measured from the pedestrian.

[0071] 14 is a block diagram showing the overall configuration of an authentication control system according to the fourth embodiment. Compared with the above-mentioned authentication control system 1000, the authentication control system 1000b is configured such that the authentication control device 200 is replaced with an authentication control device 200b and the cameras 310-340 are replaced with thermal cameras 310a-340a. The other configurations are the same as those of the authentication control system 1000.

[0072] Each of the thermo cameras 310a to 340a is installed at the entrance of the passage 400b and is connected to the network N. Each of the thermo cameras 310a to 340a is a device including a predetermined photographing device and a device for measuring body surface temperature. The photographing device may be, for example, a stereo camera. The thermo cameras 310a, etc. photograph the bodies, including the faces, of the pedestrians U1 to U3, and transmit the photographed images to the authentication control device 200b via the network N. The thermo cameras 310a, etc. measure the temperature in the photographing target area, generate a thermographic image showing the temperature distribution, and transmit the thermographic image to the authentication control device 200b via the network N.

[0073] 15 is a block diagram showing a configuration of an authentication control device 200b according to the fourth embodiment. Compared to the above-mentioned authentication control device 200, the storage unit 210 of the authentication control device 200b is configured such that the program 211 is replaced with a program 211b, and a predetermined value 213 and user management information 214 are added. Also, compared to the above-mentioned authentication control device 200, the control unit 240 of the authentication control device 200b is configured such that the acquisition unit 241 and the decision unit 244 are replaced with an acquisition unit 241b and a decision unit 244b. The other configurations are the same as those of the authentication control device 200.

[0074] The program 211b is a computer program in which the process of the authentication control method according to the fourth embodiment is implemented. The predetermined value 213 is a threshold value for comparing and determining the body surface temperature. For example, the predetermined value 213 may be 37.5 degrees. The user management information 214 is information for managing user information. The user management information 214 is information in which a user ID 2141 and a body surface temperature history 2142 are associated with each other. The body surface temperature history 2142 is a measurement history of the body surface temperature of the corresponding user (pedestrian). For example, if the pedestrian is an employee, the body surface temperature is measured daily by a thermal camera 310a or the like, and the body surface temperature history 2142 may be added to the user management information 214 in association with the user ID 2141 each time. The body surface temperature history 2142 may be an average value of the measured values. For example, the average value may be recalculated each time the temperature is measured.

[0075] The acquisition unit 241b further includes a function of a body surface temperature acquisition means for acquiring a body surface temperature measured from a walker. The decision unit 244b decides at least one of a display mode and a light-emitting target area so that the body surface temperature is emphasized when the body surface temperature is equal to or higher than the predetermined value 213 compared to when the body surface temperature is less than the predetermined value 213. Specifically, when the body surface temperature is equal to or higher than the predetermined value 213, the decision unit 244b may change the light-emitting color, the blinking pattern, the brightness, and the size of the light-emitting target area compared to other cases. For example, in this case, the decision unit 244b decides to set the light-emitting color to a color different from the above, to make the blinking pattern shorter than normal, to make the brightness brighter than normal, and to make the light-emitting target area wider than normal. Furthermore, the decision unit 244b may decide the predetermined value 213 based on the body surface temperature history 2142 of the walker, and decide at least one of a display mode and a light-emitting target area according to a comparison result between the acquired body surface temperature and the decided predetermined value 213.

[0076] Fig. 16 is a flowchart showing the flow of the authentication control method according to the fourth embodiment. Here, the thermo cameras 310a etc. photograph pedestrians U1 to U3, measure their temperatures, and generate thermographic images. Then, the thermo cameras 310a etc. transmit the photographed images and thermographic images to the authentication control device 200b via the network N. Steps S401 to S404 and S407 are the same as those in Fig. 8 described above.

[0077] In parallel with step S401, the acquisition unit 241b receives thermographic images from each of the thermo cameras 310a to 340a via the network N, compares the thermographic images with the captured images, and acquires the body surface temperature of the face region of each pedestrian (S401b).

[0078] After steps S403, S404, and S401b, the determination unit 244b performs a body surface temperature comparison process (S404b). FIG. 17 is a flowchart showing the flow of the body surface temperature comparison process according to the fourth embodiment. First, the determination unit 244b determines whether the face authentication is successful (S501). Specifically, the determination unit 244b determines whether the face authentication result acquired in step S403 indicates authentication success or failure. If it is determined that the authentication is successful, the determination unit 244b specifies the user ID included in the face authentication result (S502). Then, the determination unit 244b acquires the body surface temperature history 2142 associated with the specified user ID 2141 from the user management information 214 (S503). Next, the determination unit 244b calculates an average value from the acquired body surface temperature history 2142 (S504). Then, the determination unit 244b determines the predetermined value 213 based on the calculated average value (S505). For example, the determination unit 244b determines (updates) a temperature obtained by adding 1 degree to the calculated average value as the predetermined value 213. After that, the determination unit 244b compares the body surface temperature acquired in step S401b with the determined predetermined value 213 to obtain a comparison result (S506). Note that if it is determined that the authentication has failed in step S501, there is no comparison result and the process returns to FIG. 16.

[0079] Returning to Fig. 16, the description will be continued. After step S404b, the determination unit 244b determines a light emission target area including the specified position based on the face recognition result and the comparison result (S405b). For example, when the comparison result indicates a predetermined value or more, the determination unit 244b may determine a light emission target area that is wider than when the comparison result indicates a value less than the predetermined value.

[0080] Furthermore, the determination unit 244b determines the display mode based on the face authentication result and the comparison result (S406b). For example, when the comparison result indicates a predetermined value or more, the determination unit 244b may determine the display mode to be a different color (other than red or blue) or to blink compared to when the comparison result indicates less than the predetermined value. Note that steps S405b and S406b may be executed in parallel or in series.

[0081] After steps S405 and S406, the display control unit 245 performs display control according to the display mode for the light emitting element corresponding to the light emitting target area (S407). This makes it easier for the pedestrian to recognize that his / her body temperature may be high, and makes it easier for security guards to recognize him / her and call out to him / her.

[0082] In this manner, the present embodiment can achieve the same effects as the above-described embodiment, and further contributes to preventing the spread of infectious diseases.

[0083] <Embodiment 5> The fifth embodiment is a modified example of the second to fourth embodiments. In the fifth embodiment, a notification is made by a speaker or an output is made to a terminal for an administrator depending on the face authentication result. FIG. 18 is a block diagram showing the overall configuration of an authentication control system 1000c according to the fifth embodiment. In the authentication control system 1000c, the authentication control device 200 is replaced with an authentication control device 200c, and a directional speaker 350 and a management terminal 500 are added, compared to the above-mentioned authentication control system 1000. The other configurations are the same as those of the authentication control system 1000.

[0084] The directional speaker 350 is a highly directional speaker installed in the passage 400c. Therefore, the directional speaker 350 can transmit sound waves more clearly than usual in the output direction. The directional speaker 350 is connected to the network N, and outputs a predetermined warning in the output direction instructed by the authentication control device 200c.

[0085] The management terminal 500 is an information processing device that is operated and viewed by security guards and facility personnel. The management terminal 500 is connected to a network N, and displays on its screen the captured image and the biometric authentication result received from the authentication control device 200c.

[0086] 19 is a block diagram showing a configuration of an authentication control device 200c according to the fifth embodiment. Compared with the above-mentioned authentication control device 200, the authentication control device 200c has the program 211 replaced with a program 211c, and an output unit 248 and a transmission unit 249 added. The other configurations are the same as those of the authentication control device 200.

[0087] The program 211c is a computer program in which the processing of the authentication control method according to the fifth embodiment is implemented. When the biometric authentication result indicates authentication failure, the output unit 248 outputs a predetermined warning to the directional speaker 350 via the network N toward the identified position. Alternatively, the output unit 248 may output a predetermined warning toward the position where the security guard is standing. When the biometric authentication result indicates authentication failure, the transmission unit 249 transmits the captured image and the biometric authentication result to the management terminal 500 via the network N.

[0088] The authentication control device 200c may acquire the body surface temperature measured from the walker as in the above-mentioned embodiment 4. At this time, the output unit 248 may further output the above-mentioned predetermined warning when the body surface temperature is equal to or higher than the predetermined value. Furthermore, when the body surface temperature is equal to or higher than the predetermined value, the transmission unit 249 may further transmit the body surface temperature or the determination result thereof to the management terminal 500 via the network N. Alternatively, when the body surface temperature is equal to or higher than the predetermined value, the transmission unit 249 may transmit display information corresponding to the body surface temperature or the determination result, information specifying a display mode or display area to the management terminal 500 via the network N. Here, the display mode may be a color, a blinking pattern, or brightness on the screen of the management terminal 500. Furthermore, the display area is an area within the screen of the management terminal 500 that displays the captured image, the biometric authentication result, the body surface temperature, and the like. For example, when the body surface temperature is equal to or higher than the predetermined value, a display mode or display area different from that when the face authentication has failed may be used. Specifically, when the body surface temperature is equal to or higher than a predetermined value, the screen may be displayed in a different color, with a shorter blinking pattern, brighter brightness, and a larger display area than when face recognition has failed, thereby emphasizing the need to check the health condition.

[0089] In this way, the present embodiment can achieve the same effects as the above-mentioned embodiment. Furthermore, the present embodiment can more clearly notify the pedestrian or the security guard that the authentication has failed. Furthermore, the pedestrian, the security guard, and other related parties can more easily recognize the difference in the authentication results.

[0090] <Embodiment 6> The sixth embodiment is a modified example of the second embodiment. Fig. 20 is a block diagram showing the configuration of an authentication control device 200d according to the sixth embodiment. Compared to the above-mentioned authentication control device 200, the storage unit 210 of the authentication control device 200d is configured such that the program 211 is replaced with a program 211d and a face information DB 215 is added. Also, compared to the above-mentioned authentication control device 200, the control unit 240 of the authentication control device 200d is configured such that the authentication control unit 242 is replaced with an authentication control unit 242d.

[0091] The program 211d is a computer program in which the processing of the authentication control method according to the sixth embodiment is implemented.

[0092] The face information DB 215 corresponds to the face information DB 110 of the authentication device 100 described above, and a plurality of user IDs 2151 and face feature information 2152 are associated with each other.

[0093] The authentication control unit 242d performs facial authentication by comparing facial feature information extracted from the facial area of ​​the user (pedestrian) included in the acquired captured image with the facial feature information 2152 stored in the memory unit 210, thereby obtaining a facial authentication result.

[0094] Fig. 21 is a flowchart showing the flow of an authentication control method according to embodiment 6. In Fig. 21, step S402 in the above-mentioned Fig. 8 is replaced with steps S402a and S402b.

[0095] After step S401, the acquisition unit 241 extracts facial feature information from the face area of ​​each user in the acquired captured image (S402a). Then, the authentication control unit 242d compares the extracted facial feature information with the facial feature information 2152 in the face information DB 215 for each user (S402b).

[0096] In this way, the sixth embodiment can achieve the same effects as the second embodiment. Of course, the sixth embodiment can be modified in any of the ways described above for the third to fifth embodiments.

[0097] <Other embodiments> In the above embodiment, the present disclosure has been described as a hardware configuration, but is not limited to this. Any process of the present disclosure can be realized by causing a CPU to execute a computer program.

[0098] In the above example, the program can be stored and provided to the computer using various types of non-transitory computer readable media. The non-transitory computer readable media includes various types of tangible storage media. Examples of the non-transitory computer readable media include magnetic recording media (e.g., flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (e.g., magneto-optical disks), CD-ROM (Read Only Memory), CD-R, CD-R / W, DVD (Digital Versatile Disc), and semiconductor memory (e.g., mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (Random Access Memory)). The program may also be provided to the computer by various types of transitory computer readable media. Examples of the transitory computer readable media include electric signals, optical signals, and electromagnetic waves.
