[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 designated by the same reference numerals, and for clarity of explanation, duplicate explanations will be omitted as necessary.

[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 a photographing 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 a photographing 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 predetermined passage from an image captured by a photographing device. 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, etc.

[0017] The authentication control unit 12 obtains a biometric authentication result between the obtained biometric information and the biometric information of multiple people. If the biometric information of multiple people is stored in advance in the authentication control device 10, the authentication control unit 12 performs authentication processing. Alternatively, if 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 specifying unit 13 analyzes the captured image to specify the position of a pedestrian on the passage. 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 specified position.

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

[0020] Next, the authentication control unit 12 acquires a biometric authentication result by comparing the biometric information acquired in step S11 with 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 controls the display of the biometric authentication result acquired in step S12 on the light-emitting elements corresponding to the light-emitting target area including the position identified in step S13 (S14).

[0021] In this way, according to this embodiment, the biometric authentication result of a pedestrian can be displayed near the feet of the pedestrian, thereby enabling the biometric authentication result of an authentication target to be properly notified in a walk-through authentication system.

[0022] The authentication control device 10 includes a processor, a memory, and a storage device (not shown). 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. This allows the processor to implement 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. Furthermore, some or all of the components of each device may be realized by general-purpose or dedicated circuits, processors, etc., or a combination of these. These may be configured by a single chip, or by multiple chips connected via a bus. Some or all of the components of each device may be realized by a combination of the above-mentioned circuits, etc., and programs. Furthermore, a CPU (Central Processing Unit), GPU (Graphics Processing Unit), 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 decentralized. For example, the information processing devices, circuits, etc. may be realized as a client-server system, a cloud computing system, or the like, connected via a communication network. Furthermore, the functions of the authentication control device 10 may be provided in the form of SaaS (Software as a Service).

[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 multiple pedestrians U1 to U3 walking along a passage 400 on light-emitting elements located near the feet of each pedestrian. In the following description, biometric authentication is defined as face authentication, and biometric information is defined as facial feature information, but other technologies that use captured images can be applied to biometric authentication and biometric information.

[0026] The authentication control system 1000 includes an authentication device 100, an authentication control device 200, cameras 310 to 340, and light-emitting elements 411 to 414. The authentication device 100, the authentication control device 200, the cameras 310 to 340, and the light-emitting elements 411 to 414 are connected to each other 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 exits, and multiple light-emitting elements 411-414 buried under the floor. In particular, the light-emitting elements 411-414 are arranged at predetermined intervals under the floor in a predetermined section of the passage 400, and are arranged so as to roughly correspond to the positions of pedestrians. Each of the cameras 310-340 captures an image of a predetermined area of ​​the passage 400 from a respective angle and transmits the captured image to the authentication control device 200 via the network N. Note that at least one camera 310 is sufficient. The camera 310 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 may be two or more light-emitting elements 411, but preferably, the passage 400 is filled with them in a grid pattern. The light-emitting elements 411 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 to display a plurality of adjacent light emitting elements 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 the configuration of an authentication device 100 according to the second embodiment. The authentication device 100 includes a face information database (DB) 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 facial feature information 112 for the user ID in association with each other. The facial feature information 112 is a collection of feature points extracted from a facial image. The authentication device 100 may delete the facial feature information 112 from the facial feature DB 110 in response to a request from a registered user of the facial feature information 112. Alternatively, the authentication device 100 may delete the facial feature information 112 after a certain period of time has elapsed since the registration of the facial 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 detected 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 facial feature information. The registration unit 140 associates the issued user ID 111 with facial feature information 112 extracted from the registered image and registers them in the facial information DB 110. The authentication unit 150 performs facial authentication using the facial feature information 112. Specifically, the authentication unit 150 compares the facial feature information extracted from the facial 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 present) 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 receives a face information registration request from an information registration terminal via the 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 and associates the user ID 111 with face feature information 112 to register it 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 it 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 the 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 between 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 a message to the authentication control device 200 indicating that face authentication was successful and the identified user ID 111 (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 the facial 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 received to several days prior. This may improve the matching speed. Furthermore, if the preferential matching fails, it may be possible to perform matching with all of the remaining facial feature information.

[0036] Returning to Figure 3, the explanation will continue. The authentication control device 200 is an information processing device that performs face authentication on pedestrians (users) U1 to U3 included in captured images 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 configured redundantly with multiple servers, and each functional block may be implemented 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 allowed to pass 212. The program 211 is a computer program that implements the processing of the authentication control method according to the second embodiment. The maximum number of people allowed to pass 212 is the maximum number of pedestrians who can pass through the passage 400. The maximum number of people allowed to pass 212 is information that is 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 storing 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, i.e., 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. As a result, 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 for each walker from the authentication device 100.

[0042] The position identifying unit 243 is an example of the position identifying unit 13. It 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, if 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-emitting target area based on the face authentication result. That is, at least one of the display mode and the light-emitting target area will differ 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, such as the light-emitting color, light-emitting pattern (blinking pattern), light-emitting time, etc. Furthermore, the light-emitting target area refers to a 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 facial authentication result indicates authentication failure, the determination unit 244 may determine the light-emitting target region to be larger than when the facial authentication result indicates authentication success. That is, when the facial authentication result indicates authentication failure, the determination unit 244 may increase the region size. Furthermore, when the facial authentication result indicates authentication failure, the determination unit 244 may determine the light-emitting target region to include the pedestrian's predicted traveling direction from the captured image. For example, when the facial authentication is successful, the determination unit 244 may determine the vicinity of the pedestrian's feet as the light-emitting target region, and when the facial authentication is unsuccessful, the determination unit 244 may determine a wider region from the pedestrian's feet toward the pedestrian's traveling direction as the light-emitting target region. Alternatively, when the facial authentication is unsuccessful, the determination unit 244 may determine the pedestrian's movement trajectory as the light-emitting target region.

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

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

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

[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 elements corresponding to the determined target light-emitting area. That is, the display control unit 245 identifies the light-emitting elements corresponding to the target light-emitting area, and transmits a control signal based on the display mode to the identified light-emitting elements 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 elements 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 elements 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 the passage 400 from the maximum number of people who can pass through 212 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 embedded near an entrance / exit of the passage 400.

[0051] 8 is a flowchart showing the flow of the authentication control method according to the present 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 sends a face authentication request to the authentication device 100 for each pedestrian included in the captured image (S402). Specifically, the acquisition unit 241 extracts a face region of each pedestrian from the captured image and acquires facial feature information from the face region. Then, the authentication control unit 242 includes the facial feature information for each pedestrian in a face authentication request and transmits it to the authentication device 100 via the network N. Then, the authentication control unit 242 acquires a face authentication result for each pedestrian from the authentication device 100 (S403).

[0053] In parallel with step S401, the position specifying unit 243 specifies the position of the pedestrian by analyzing the captured image (S404). That is, the position specifying 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 identified position based on the face authentication result (S405). Furthermore, the determination unit 244 determines a display mode based on the face authentication result (S406). Note that steps S405 and S406 may be executed in parallel or serially.

[0055] After steps S405 and S406, the display control unit 245 performs display control according to the display mode for the light-emitting elements corresponding to the target light-emitting area (S407). FIG. 9 is a diagram illustrating an example of display control according to the second embodiment. Here, it is assumed that pedestrians U1 and U2 are moving toward the back of the passage 400, and pedestrian U3 is moving toward the front. It is also assumed that face authentication for pedestrians U1 and U3 has been successful, while face authentication for pedestrian U2 has failed. Therefore, the determination unit 244 determines the target light-emitting area for pedestrian U2 (display 402) to be larger than the target light-emitting areas for pedestrians U1 and U3 (displays 401 and 403). The displays 401 and 403 have lighting areas near the feet of pedestrians U1 and U3. The determination unit 244 may also determine the displays 401 and 403 so as to follow the movement of pedestrians U1 and U3. The display 402 may be an example of lighting the movement trajectory of pedestrian U2. The determination unit 244 also indicates that it has determined that the display mode (display 402) of the pedestrian U2 is to be displayed more emphatically than the display modes (displays 401 and 403) of the pedestrians U1 and U3.

[0056] FIG. 10 is a diagram illustrating another example of display control according to the second embodiment. Here, a case is shown in which, if authentication fails, the traveling direction of the pedestrian is set as the light-emitting target area. It is assumed that the pedestrian U2 is moving toward the back of the passage 400, and face authentication has failed. In this case, the determination unit 244 analyzes captured images from the most recent image to the previous few frames, identifies the displacement of the area corresponding to the pedestrian U2, and predicts the traveling direction. The determination unit 244 then determines the light-emitting target area, including the traveling direction of the pedestrian U2. Display 402a is an example in which the traveling direction of the pedestrian U2 is set as the light-emitting target area. This allows the pedestrian U2 to more directly recognize that face authentication has failed, and can facilitate 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 authentication control process described above. 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 determines whether the detected number of people is equal to or less than the maximum number of people who can pass 212 (S411). If the result of step S411 is YES, that is, if the detected number of people is equal to or less than the maximum number of people who can pass 212, the calculation unit 247 calculates the remaining number of people who can pass from the maximum number of people who can pass 212 and the detected number of people (S412). Then, the display control unit 245 performs display control so that predetermined light-emitting elements display the calculated remaining number of people who can pass (S413).

[0059] On the other hand, if step S411 returns NO, that is, if the detected number of people exceeds the maximum number of people allowed to pass 212, the display control unit 245 performs display control to cause predetermined light-emitting elements to display a warning (S414). The warning display may be, for example, light-emitting elements embedded in rows on both ends of the passage 400 to 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, if the facial authentication result indicates authentication failure, the movement trajectory of the pedestrian may be displayed on the passageway 400. As an example, if the facial authentication result indicates authentication failure, the display control unit 245 performs display control to maintain the lighting of the light-emitting elements corresponding to the light-emitting target areas. For example, display 402 in FIG. 9 shows a state in which pedestrian U2 has failed facial authentication multiple times in succession. This makes it easier for pedestrian U2 to properly recognize that he or she has failed facial authentication. Furthermore, it becomes easier for surrounding security guards and the like to properly recognize that pedestrian U2 has failed facial authentication, making it easier for them to call out to pedestrian U2.

[0061] Then, it is assumed that the face authentication of the pedestrian U2 is successful thereafter. In other words, when the face authentication result indicates success after an authentication failure, the display control unit 245 performs display control to turn off the light-emitting elements that remained lit 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 and the like.

[0062] Alternatively, the display of the movement trajectory may be achieved as follows. First, the authentication control device 200 further includes a storage unit that extracts body shape features of a pedestrian from a captured image, associates the extracted body shape features with identified positions, and stores them in the history storage unit. Then, when the biometric authentication result indicates authentication failure, the determination unit acquires, from the history storage unit, positions associated with the body shape features of the pedestrian whose authentication failed, generates a movement trajectory of the pedestrian using the acquired positions, and determines the movement trajectory as the light-emitting target area. Then, the display control unit performs display control on the light-emitting elements corresponding to the determined movement trajectory. This makes it possible to display the movement trajectory of the pedestrian 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 depending on the success or failure of the authentication result as follows. First, the display control unit 245 performs display control to cause the light-emitting elements corresponding to the light-emitting target area to be illuminated in a first manner from after the position is identified until the pedestrian's biometric authentication result is acquired. The first illumination may be, for example, yellow. Next, after the biometric authentication result is acquired, the display control unit 245 selects either the second illumination or the third illumination depending on the success or failure of the biometric authentication result. For example, the second illumination may be blue when facial authentication is successful, and the third illumination may be red when facial authentication is unsuccessful. Then, the display control unit 245 performs display control to cause the light-emitting elements corresponding to the light-emitting target area to be illuminated in the selected manner. Note that the second illumination and the third illumination may be brighter than the first illumination. Alternatively, the light may be turned off instead of the first illumination. In other words, the light may be turned off during authentication and turned on when the authentication result is obtained according to the authentication result. This also makes it possible to appropriately notify pedestrians, security guards, and the like of the difference in authentication results.

[0064] In this embodiment, the display of the success or failure of the authentication result may be differentiated between facility employees and guests. In this case, the storage unit 210 is assumed to have previously stored therein the employee user ID and attributes (affiliation), etc., associated with each other. The determination unit 244 then identifies the attributes of the walker based on the biometric authentication result. For example, if the biometric authentication result is successful, the determination unit 244 identifies the user ID included in the biometric authentication result and acquires the attributes associated with the identified user ID from the storage unit 210. If the attributes are acquired, the person is an employee, so the determination unit 244 makes the display mode more subdued compared to guests. Alternatively, in the case of an employee, the determination unit 244 makes the light-emitting target area narrower compared to guests. In other words, if the attributes cannot be acquired, the person is a guest, so the determination unit 244 makes the display mode more exaggerated compared to employees. Alternatively, in the case of a guest, the determination unit 244 makes the light-emitting target area wider compared to employees. This improves hospitality to guests.

[0065] <Embodiment 3> The third embodiment is a modification of the second embodiment described above. 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 authentication control system 1000 described above, the authentication control system 1000a is configured such that the authentication control device 200 is replaced 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 one of the walkers U1-U3 applies a load with its foot, 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 has a configuration similar to that shown in FIG. 7 and is therefore not shown in the figure. However, the authentication control device 200a differs from the authentication control device 200 in the program 211, acquisition unit 241, and position identification unit 243. The program 211 stored in the storage unit 210 of the authentication control device 200a is a computer program that implements the processing of the authentication control method according to the third embodiment. The acquisition unit 241 included in the authentication control device 200a further includes the function of a detection result acquisition means that acquires the detection results obtained by the pressure sensor. The position identification unit 243 included in the authentication control device 200a further takes the detection results into consideration 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 results (S404a). The subsequent steps are the same as those in Fig. 8.

[0069] In this way, in the third embodiment, the detection results of the pressure sensor are used in addition to 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 fourth embodiment is a modification of the second and third embodiments described above. In recent years, from the viewpoint of preventing the spread of infectious diseases, determining entry eligibility has increasingly involved checking a person's health condition at the time of entry in addition to checking against pre-registered information. Therefore, in a walk-through authentication system, it is desirable to display information according to the body surface temperature of a pedestrian in addition to biometric authentication. Therefore, in the fourth embodiment, in addition to the second and third embodiments described above, 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 to the above-described 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 thermal cameras 310a to 340a is installed at the entrance / exit of the passage 400b and is connected to the network N. Each of the thermal cameras 310a to 340a is a device including a predetermined photographing device and a body surface temperature measuring device. The photographing device may be, for example, a stereo camera. The thermal 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 thermal cameras 310a, etc. measure the temperature in the photographing target area, generate thermographic images showing the temperature distribution, and transmit the thermographic images to the authentication control device 200b via the network N.

[0073] 15 is a block diagram showing the configuration of an authentication control device 200b according to the fourth embodiment. Compared to the above-described 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-described authentication control device 200, the control unit 240 of the authentication control device 200b is configured such that the acquisition unit 241 and the determination unit 244 are replaced with an acquisition unit 241b and a determination unit 244b. The other configurations are the same as those of the authentication control device 200.

[0074] The program 211b is a computer program that implements the processing of the authentication control method according to the fourth embodiment. The predetermined value 213 is a threshold value used for comparing and determining body surface temperatures. For example, the predetermined value 213 may be 37.5°C. The user management information 214 is information for managing user information. The user management information 214 is information in which a user ID 2141 is associated with a body surface temperature history 2142. 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 using a thermal camera 310a or the like. Therefore, the body surface temperature history 2142 may be associated with the user ID 2141 and added to the user management information 214 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 a measurement is performed.

[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 pedestrian. The determination unit 244b determines at least one of a display mode and a light-emitting target area so that, when the body surface temperature is equal to or greater than a predetermined value 213, the body surface temperature is emphasized more than when the body surface temperature is less than the predetermined value 213. Specifically, when the body surface temperature is equal to or greater than the predetermined value 213, the determination unit 244b may change the light-emitting color, blinking pattern, brightness, and size of the light-emitting target area compared to other cases. For example, in this case, the determination unit 244b may determine the light-emitting color to be different from the above, the blinking pattern to be shorter than normal, the brightness to be brighter than normal, and the light-emitting target area to be wider than normal. Furthermore, the determination unit 244b may determine the predetermined value 213 based on the body surface temperature history 2142 of the pedestrian, and determine 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 determined predetermined value 213.

[0076] Fig. 16 is a flowchart showing the flow of the authentication control method according to the fourth embodiment. Here, the thermal cameras 310a and the like photograph pedestrians U1 to U3, measure their temperatures, and generate thermographic images. The thermal cameras 310a and the like then 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 face authentication has been 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 authentication has been successful, the determination unit 244b identifies a user ID included in the face authentication result (S502). Then, the determination unit 244b acquires the body surface temperature history 2142 associated with the identified 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 a predetermined value 213 based on the calculated average value (S505). For example, the determination unit 244b determines (updates) the temperature obtained by adding 1 degree to the calculated average value as the predetermined value 213. Thereafter, 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 failed in step S501, there is no comparison result and the process returns to FIG. 16.

[0079] 16, the description will be continued. After step S404b, the determination unit 244b determines a target light emission area including the identified position based on the face authentication 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 wider target light emission area compared to 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 flash compared to when the comparison result is 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 elements corresponding to the target light-emitting area (S407). This makes it easier for the pedestrian to realize that their body temperature may be high, making it easier for security guards and others to recognize them and call out to them.

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

[0083] <Embodiment 5> The fifth embodiment is a modification of the second to fourth embodiments described above. In the fifth embodiment, notification is made by a speaker or output is made to a terminal for an administrator according to 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. Compared to the above-described authentication control system 1000, the authentication control system 1000c replaces the authentication control device 200 and adds a directional speaker 350 and an administration terminal 500. 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 passageway 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 operated and viewed by security guards and facility personnel. The management terminal 500 is connected to the network N and displays on its screen the captured image and biometric authentication result received from the authentication control device 200c.

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

[0087] The program 211c is a computer program that implements the processing of the authentication control method according to the fifth embodiment. 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, directed toward the identified position. Alternatively, the output unit 248 may output the 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 a body surface temperature measured from a walker, as in the fourth embodiment described above. At this time, the output unit 248 may further output the predetermined warning if the body surface temperature is equal to or higher than a predetermined value. Furthermore, if the body surface temperature is equal to or higher than a predetermined value, the transmission unit 249 may further transmit the body surface temperature or a determination result thereof to the management terminal 500 via the network N. Alternatively, if the body surface temperature is equal to or higher than a predetermined value, the transmission unit 249 may transmit display information, a display mode, or information specifying a display area according to the body surface temperature or the determination result 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 on the screen of the management terminal 500 that displays the captured image, the biometric authentication result, the body surface temperature, etc. For example, if the body surface temperature is equal to or higher than a predetermined value, a display mode or display area different from that used when face authentication fails may be used. Specifically, if the body surface temperature is above 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 authentication fails, thereby further emphasizing the need to check the user's health condition.

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

[0090] <Embodiment 6> The sixth embodiment is a modification 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-described 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-described 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 associates a plurality of user IDs 2151 with face feature information 2152 .

[0093] The authentication control unit 242d performs facial authentication by comparing the 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 the authentication control method according to the embodiment 6. In Fig. 21, step S402 in Fig. 8 described above is replaced with steps S402a and S402b.

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

[0096] In this way, the sixth embodiment can also 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> Although the above-described embodiment has been described as a hardware configuration, the present disclosure is not limited to this. Any processing in the present disclosure can also be realized by causing a CPU to execute a computer program.

[0098] In the above example, the program can be stored and supplied to a computer using various types of non-transitory computer-readable media.
