  Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings.

<System overview>
First, an outline of an entrance / exit management system including the entrance / exit management device according to the present embodiment will be described.

  FIG. 1 is a diagram showing an overview of an entrance / exit management system including an entrance / exit management apparatus according to the present embodiment.

  As shown in FIG. 1, the entrance / exit management system 100 is a system that manages the entry of a person 120 into the management target area 110 for the management target area 110.

  The entrance / exit management system 100 performs ID authentication on the person 120 located at the entrance 130 of the management target area 110 and opens the door 140 of the entrance 130 that is normally closed only when the ID authentication is successful. . Here, the ID authentication is based on the ID information of the IC card (terminal) 121 possessed by the person 120 and determines whether or not the person 120 is an authorized person having the right to enter the management target area 110. It is a thing.

  The IC card 121 possessed by the person 120 holds ID information such as a character string assigned to the authorized person. When the IC card 121 is brought close to the card reader 141 installed in the vicinity of the door 140, the ID information to be held is transmitted to the card reader 141 by radio. The entrance / exit management device 300 of the entrance / exit management system 100 performs ID authentication based on the ID information received by the card reader, and when the ID authentication is successful, opens the door 140 as described above.

  In other words, no person 120 can enter the management target area 110 unless the ID authentication is successful.

  However, as described above, it is troublesome to perform the IC card operation for bringing the IC card 121 close to the card reader 141 every time it enters the management target area 110. Further, for example, when a large number of authorized persons enter the management target area 110 in a short time, each person 120 performs the IC card operation in order, and there is a possibility that the waiting time until the entry increases. In order to avoid this, a large number of card readers 141 must be installed, which increases the cost of the system.

  Therefore, the entrance / exit management system 100 includes a camera 150 that captures the face of the person 120 located at the entrance 130 of the management target area 110, and a face detection device 200 that performs face authentication on the captured face. Then, the entrance / exit management device 300 acquires face information indicating the result of face authentication from the face detection device 200 via a communication network 160 such as a LAN (Local Area Network), and face authentication is performed a predetermined number of times for the same authorized person. If successful, the ID authentication is omitted and the door 140 is opened.

  In other words, the entrance / exit management system 100 does not perform ID authentication uniformly, but permits an authorized person who has succeeded in face authentication many times to enter the management target area 110 with successful face authentication. To do.

  Face authentication may be less accurate than ID authentication. However, it can be said that among the authorized persons who have succeeded in ID authentication, the authorized persons who have succeeded in face authentication multiple times have succeeded in face authentication with high accuracy. Therefore, even if the ID authentication is omitted when the face authentication has been successful a predetermined number of times or more, it is possible to ensure the same security as when the ID authentication is performed. And since the ID authentication is omitted, the IC card operation becomes unnecessary.

  Further, since face authentication can be performed if a face is projected with a predetermined image quality on the photographed image, it can be performed in a shorter time than ID authentication by IC card operation. Therefore, it is possible to prevent the above-described waiting time or increase in cost.

<System configuration>
Next, the configuration of the entrance / exit management system 100 will be described.

  FIG. 2 is a system configuration diagram showing an example of the configuration of the entrance / exit management system 100.

In FIG. 2, the entrance / exit management system 100 manages the entry of a person in each of the _first to Nth (N is an integer of 2 or more) management target areas 110 _{1 to} 110 _N. Note that the management target area 110 managed by the entrance / exit management system 100 may be only one.

  The entrance / exit management system 100 includes a camera 150, a door 140, a card reader 141, and a door control device 142 for each management target area 110. The entrance / exit management system 100 includes a face detection device 200, an entrance / exit management device 300, and a personal computer (PC) 400 corresponding to one or a plurality of management target areas 110.

  Note that the camera 150, the card reader 141, the door control device 142, the entrance / exit management device 300, the face detection device 200, and the personal computer 400 in each management target area 110 are communicably connected via a communication network 160. Yes.

  The camera 150 is a camera that photographs the face of a person who wishes to enter the management target area 110 at the entrance 130 of the management target area 110. The camera 150 transmits the captured image to the face detection device 200.

  It should be noted that the captured image of the camera 150 needs to be an image capable of performing face authentication on the person located at the entrance 130 with high accuracy by detecting the person's face from the image. A person who intends to enter the management target area 110 usually faces his door 140 at the entrance 130. Therefore, the camera 150 is installed, for example, at the position of the average height of the human face in the vicinity of the door 140 and facing the outside (entrance side) of the management target area 110, and shoots an image of the entrance 130. .

  The door 140 is provided at the entrance of the management target area 110 and is a portion through which a person entering the management target area 110 passes. The door 140 is, for example, a door with an electronic lock or an automatic door.

  The card reader 141 is arranged in the vicinity of the door 140, and reads the ID information held by the IC card 121 when the IC card 121 distributed to the authorized person approaches at a short distance. Then, the card reader 141 transmits the acquired ID information to the entrance / exit management device 300.

  For example, when the IC card 121 is a non-contact type IC card, ID information is wirelessly transmitted to and from the card reader 141 by an electromagnetic induction method. In this case, the communication distance of the card reader 141 is about 2 mm to about 70 cm. Therefore, the card reader 141 acquires ID information from the IC card 121 only when the IC card operation is performed.

  The door control device 142 receives the door control information transmitted from the entrance / exit management device 300, and controls the opening / closing (opening / closing) of the door 140 in accordance with the received door control information.

  The opening of the door 140 includes unlocking the electronic lock of the door 140 and opening the door 140 as an automatic door. The closing of the door 140 includes locking the electronic lock of the door 140 and closing the door 140 as an automatic door. Moreover, the door control apparatus 142 shall close the door 140 in a normal state.

  The face detection device 200 performs face authentication on the face of the person included in the video received from the camera 150, and determines whether the person who entered the management target area 110 is an authorized person. Then, the face detection apparatus 200 transmits face information indicating the result of face authentication (success / failure) to the entrance / exit management apparatus 300. The configuration of the face detection apparatus 200 will be described later.

  The entrance / exit management device 300 receives the face information transmitted from the face detection device 200 and counts the number of times face authentication has been successful (hereinafter referred to as “the number of successful face authentications”) for each authorized person. The entrance / exit management device 300 temporarily opens the door 140 of the entrance 130 when the number of successful face authentications corresponding to the person located at the entrance 130 is equal to or greater than a predetermined value.

  Further, when the number of successful face authentications corresponding to the person located at the entrance 130 is less than a predetermined value, the entrance / exit management device 300 performs ID authentication using the card reader 141, and the ID authentication is successful. The door 140 of the entrance 130 is temporarily opened.

  For example, the entrance / exit management device 300 transmits door control information for instructing to temporarily open the door 140 to the door control device 142. The entrance / exit management device 300 transmits door control information instructing opening of the door 140 when the number of successful face authentications corresponding to the person located at the entrance 130 is less than a predetermined value and the ID authentication is not successful. By performing the process of not, the state where the door 140 is closed is continued.

  Further, the entrance / exit management device 300 acquires predetermined ID information other than ID information (hereinafter referred to as “permission ID information”) assigned to a terminal possessed by the authorized person when the door 140 is opened. When an event occurs, notification information for notifying the occurrence of the event is transmitted to the personal computer 400. The configuration of the entrance / exit management device 300 will be described later.

  The personal computer 400 is an information output device used by an administrator, and includes, for example, a monitor and a speaker. When receiving the notification information from the entrance / exit management device 300, the personal computer 400 displays warning information and / or outputs a warning sound.

  Note that the face detection device 200 and the entrance / exit management device 300 each process information for each management target area 110.

  Such an entrance / exit management system 100 determines whether an authorized person is located at the entrance 130 of the management target area 110 by combining ID authentication for the IC card 121 and face authentication using a captured image. The opening and closing of the door 140 can be controlled. More specifically, the entrance / exit management system 100 performs face authentication for the person located at the entrance 130, the condition that the number of successful face authentications of the person is a predetermined value or more, and further successful ID authentication. When at least one of the above conditions is satisfied, the entrance 130 can be temporarily opened.

  As a result, the entrance / exit management system 100 omits ID authentication and permits entry into the management target area 110 for an authorized person who has succeeded in face authentication for a predetermined number of times or more, thus ensuring the security of the management target area 110. However, the frequency with which ID authentication is performed can be reduced.

  In addition, the entrance / exit management system 100 may install a plurality of cameras 150 at the entrance 130 and perform face recognition on each captured video. Thereby, it is possible to reduce the possibility that face authentication is not started or fails even though the authorized person is located at the entrance 130.

<Configuration of each device>
Next, configurations of the face detection device 200 and the entrance / exit management device 300 will be described.

  FIG. 3 is a block diagram illustrating an example of the configuration of the face detection apparatus 200.

  3, the face detection apparatus 200 includes a face detection side communication unit 210, a face information storage unit 220, a face detection unit 230, and a face authentication unit 240.

  The face detection side communication unit 210 is a communication interface connected to the communication network 160, and connects to the camera 150, the entrance / exit management device 300, the personal computer 400, and the like via the communication network 160.

  The face information storage unit 220 stores face detection information for detecting the face from the image including the face. The face detection information is information representing the features of the face image, such as a face Gabor feature amount obtained from a large number of face image samples and an image pattern of each face part such as eyes and mouth.

  Further, the face information storage unit 220 associates the face authentication information for determining whether or not the detected face is the face of the authorized person with the authorization ID information of the authorized person for each face of the authorized person. Store. The face authentication information is information indicating facial features such as the ratio of the width of the face, the distance between the left and right eye corners, and the distance between the left and right mouth corners.

  The face detection information and face authentication information stored in the face information storage unit 220 are set by an administrator via a user interface (not shown) such as a monitor, keyboard, and mouse provided in the face information storage unit 220, for example. Alternatively, it may be set remotely from the personal computer 400.

  The face detection unit 230 receives a captured image from the camera 150 via the face detection side communication unit 210 and detects a face from the received captured image using the face detection information in the face information storage unit 220. Then, the face detection unit 230 outputs information indicating the detected face area or information indicating the detected face feature to the face authentication unit 240. Note that the face detection unit 230 desirably performs face detection on the captured image of the camera 150 periodically (for example, every 2 seconds).

  The face authentication unit 240 performs face authentication on the face detected by the face detection unit 230 using the face authentication information in the face information storage unit 220. The face authentication unit 240 may acquire the facial features used for the face authentication from the face detection unit 230 or may be acquired from the captured video.

  In addition, when a person stays at the entrance 130 for a long time, there is a possibility that face recognition is performed a plurality of times for the face of the same person. Therefore, for example, the face authentication unit 240 determines whether or not a plurality of face recognition results are the same person, and when a plurality of face recognition results are obtained for the same person, the first time Other face recognition results obtained until a predetermined time (for example, 10 minutes) elapses after face recognition may be discarded. That is, the face authentication unit 240 may combine a plurality of face recognition results obtained for the same person in a short time as a result of one face recognition.

  Then, the face authentication unit 240 transmits at least information indicating permission ID information of the authorized person who has succeeded in face authentication to the entrance / exit management device 300 via the face detection side communication unit 210 as face information. Note that the face authentication unit 240 may sequentially transmit information indicating the captured video and the result of face authentication to the personal computer 400 via the face detection side communication unit 210.

  The face detection apparatus 200 having such a configuration performs face authentication for determining whether or not the person is an authorized person based on the face of the person located at the entrance 130 of the management target area 110, and performs face authentication. Face information indicating the result can be sequentially transmitted to the entrance / exit management device 300.

  FIG. 4 is a block diagram illustrating an example of the configuration of the entrance / exit management device 300.

  4, the entrance / exit management device 300 includes an entrance / exit management communication unit 310, a face information acquisition unit 320, an ID information storage unit 330, an ID authentication necessity determination unit 340, an ID authentication unit 350, and a door control unit 360. Have.

  The entrance / exit management communication unit 310 is a communication interface connected to the communication network 160 and is connected to the card reader 141, the door control device 142, the face detection device 200, the personal computer 400, and the like via the communication network 160. To do.

  The face information acquisition unit 320 receives the face information transmitted from the face detection device 200 via the entrance / exit management communication unit 310. Then, the face information acquisition unit 320 outputs the received face information to the ID authentication necessity determination unit 340.

  The ID information storage unit 330 stores permission ID information. The permission ID information stored in the ID information storage unit 330 may be set by an administrator via a user interface (not shown) provided in the ID information storage unit 330 or set remotely from the personal computer 400, for example. May be.

  The ID authentication necessity determination unit 340 records the number of successful face authentications for each authorized person based on the face information input from the face information acquisition unit 320. The ID authentication necessity determination unit 340 then performs the corresponding face authentication every time the face authentication for the person located at the entrance 130 is successful (that is, every time face information indicating that the face authentication is successful is input). It is determined whether the number of successes is a predetermined value or more.

  This predetermined value is a value corresponding to the accuracy of authentication required for identifying an authorized person by face authentication, and is 3, for example.

  Then, when the number of successful face authentications is equal to or greater than a predetermined value, the ID authentication necessity determination unit 340 outputs authentication success information indicating that the person located at the entrance 130 is an authorized person to the door control unit 360. The ID authentication necessity determination unit 340 may transmit authentication success information including the corresponding ID information to the personal computer 400 via the entrance / exit management communication unit 310.

  On the other hand, if the number of successful face authentications is less than a predetermined value, the ID authentication necessity determination unit 340 instructs the ID authentication unit 350 to perform ID authentication.

  The ID authenticating unit 350 obtains and returns ID information to the card reader 141 via the entrance / exit management communication unit 310 on the condition that the ID authentication necessity determining unit 340 instructs execution of ID authentication. Request. Then, the ID authentication unit 350 receives the ID information transmitted from the card reader 141 via the entrance / exit management communication unit 310, and ID authentication for a person located at the entrance 130 based on the received ID information I do.

  More specifically, the ID authentication unit 350 refers to the ID information storage unit 330 and determines whether or not the received ID information matches any of the permission ID information. Further, the ID authentication unit 350 determines that the ID authentication is successful when there is matching permission ID information, and fails the ID authentication when there is no matching permission ID information.

  Then, when the ID authentication is successful, the ID authentication unit 350 outputs authentication success information indicating that to the door control unit 360. Note that the ID authentication unit 350 may transmit authentication success information including ID information for which ID authentication has been successful to the card reader 141 and the personal computer 400 via the entrance / exit management communication unit 310. Further, when the ID authentication fails, the ID authenticating unit 350 may output authentication failure information indicating that fact to the door control unit 360 or transmit it to the card reader 141 and the personal computer 400.

  When the authentication success information is input, the door control unit 360 transmits door control information for instructing opening of the door 140 to the door control device 142 via the entrance / exit management side communication unit 310. When the authentication failure information is input, the door control unit 360 transmits door control information instructing closing of the door 140 for a certain period to the door control device 142 via the entrance / exit management communication unit 310. Also good.

  Note that the card reader 141 preferably outputs a sound, light, or the like that prompts the person located at the entrance 130 to operate the IC card when the ID authentication unit 350 requests acquisition of the ID information. That is, it is desirable that the ID authentication unit 350 notifies the person located at the entrance 130 of the start of ID authentication when performing ID authentication through a request for acquiring ID information. For example, when the card reader 141 receives authentication success information or authentication failure information, the card reader 141 preferably outputs a sound or light indicating the result of the ID authentication.

  For example, when the personal computer 400 receives authentication success information or authentication failure information, the personal computer 400 displays text information indicating the content of the received information on the monitor.

  The entrance / exit management device 300 having such a configuration can open the entrance 130 based on the face information from the face detection device 200 if the number of successful face authentications of a person located at the entrance 130 is equal to or greater than a predetermined value. . The entrance / exit management device 300 can perform ID authentication when the number of successful face authentications is less than a predetermined value, and can open the entrance 130 upon successful ID authentication.

  Note that the face detection device 200 and the entrance / exit management device 300 are not shown, but, for example, a CPU (Central Processing Unit), a storage medium such as a ROM (Read Only Memory) storing a control program, a RAM (Random Access Memory), etc. Each having a working memory and a communication circuit. In this case, the function of each unit described above is realized by the CPU executing the control program.

  According to the entrance / exit management system 100 having such a configuration, if the number of successful face authentications of the person located at the entrance 130 is equal to or greater than a predetermined value, ID authentication can be omitted, so the number of ID authentications is reduced. I can do it. If the number of successful face authentications is greater than or equal to a predetermined value, the person at the entrance 130 is likely to be an authorized person. Therefore, the entrance / exit management system 100 can realize highly reliable entrance / exit management while reducing the number of times of ID authentication.

<Operation of entrance / exit management device>
Next, the operation of the entrance / exit management apparatus 300 will be described.

  FIG. 5 is a flowchart showing an example of the operation of the entrance / exit management device 300. For example, the entry / exit management device 300 starts the operation described below when no one is in the management target area 110. The initial value of the number of successful face authentications for each authorized person is zero.

  In step S <b> 1100, the face information acquisition unit 320 determines whether face information has been received from the face detection device 200. If the face information acquisition unit 320 has not received face information (S1100: NO), the process proceeds to step S1200.

  In step S1200, the face information acquisition unit 320 determines whether or not an instruction to end the process of managing the entry of a person into the management target area 110 is given by an administrator operation or the like. If the end of the process is not instructed (S1200: NO), the face information acquisition unit 320 returns the process to step S1100. That is, the entrance / exit management device 300 waits for reception of face information until it is instructed to end the process.

  If face information is received (S1100: YES), face information acquisition unit 320 advances the process to step S1300.

  In step S1300, the ID authentication necessity determination unit 340 determines whether face authentication for the person located at the entrance 130 is successful based on the received face information. If face authentication fails (S1300: NO, second condition), ID authentication necessity determination unit 340 advances the process to step S1400.

  In step S1400, the ID authentication unit 350 uses the card reader 141 to notify the person located at the entrance 130 of the IC card operation, acquires the ID information of the IC card 121, and performs ID authentication. carry out.

  In step S1500, the ID authentication unit 350 determines whether or not the ID authentication is successful, that is, whether or not the acquired ID information is permission ID information. If the ID authentication fails (S1500: NO), the ID authentication unit 350 advances the process to step S1600. If the ID authentication is successful (S1500: YES), the ID authentication unit 350 advances the process to step S1900 described later.

  In step S1600, ID authentication unit 350 notifies authentication failure (authentication NG) to card reader 141 or personal computer 400 by outputting authentication failure information, and the process returns to step S1200. That is, the door control unit 360 keeps the door 140 closed.

  On the other hand, if face authentication is successful (S1300: YES), ID authentication necessity determination unit 340 advances the process to step S1700.

  In step S <b> 1700, the ID authentication necessity determination unit 340 records the number of successful face authentications of the authorized person who has succeeded in face authentication this time by incrementing by one.

  In step S1800, the ID authentication necessity determination unit 340 determines whether or not the number of successful face authentications of the authorized person who has succeeded in face authentication this time is greater than or equal to a predetermined value. If the number of successful face authentications is less than the predetermined value (S1800: NO, first condition), ID authentication necessity determination unit 340 advances the process to step S1400 described above. That is, the ID authentication necessity determination unit 340 performs ID authentication.

  On the other hand, if the number of successful face authentications is greater than or equal to a predetermined value (S1800: YES), ID authentication necessity determination unit 340 advances the process to step S1900.

  In step S1900, the ID authentication unit 350 or the ID authentication necessity determination unit 340 outputs authentication success information. As a result, the door control unit 360 transmits door control information instructing to open the door 140 for a predetermined time (for example, 5 seconds), and the process returns to step S1200. Note that the door 140 may be closed after the predetermined time has elapsed by the door control unit 360 transmitting door control information instructing the closing to the door control device 142, or the door control device 142 may be autonomous. It may be done automatically.

  Then, when instructed to end the process (S1200: YES), the face information acquisition unit 320 ends the series of processes.

  The ID authentication necessity determination unit 340 counts the elapsed time since the number of successful face authentications is counted as 1 for each authorized person using a timer, and the elapsed time reaches a first threshold (for example, one week). As a condition, the number of successful face authentications may be initialized. Alternatively, the ID authentication necessity determination unit 340 is provided on the condition that the number of successful face authentications reaches a second threshold (for example, 10 times) or that a predetermined time (for example, the end of every month) has arrived for each authorized person. As an alternative, the number of successful face authentications may be initialized.

  Further, the ID authentication necessity determination unit 340 may initialize the number of successful face authentications for each authorized person when the face authentication fails and the ID authentication is successful. That is, the number of successful face authentications that is compared with a predetermined value in step S1800 may be the number of successful face authentications for each authorized person.

  By such an operation, the entrance / exit management device 300 permits an authorized person who has succeeded in face authentication a predetermined number of times or more to enter the management target area 110 as it is, and for other people, an IC card. The entry into the management target area 110 can be permitted with the successful D authentication by the operation.

<System operation>
Next, the operation of the entrance / exit management system 100 will be described.

  FIG. 6 is a sequence diagram showing an example of the operation of the entrance / exit management system 100. Here, the description will focus on the main operations.

  When a person passes through the entrance of the management target area 110 (S2010), and a captured image including the person's face is transmitted from the camera 150 (S2020), the face detection unit 230 of the face detection apparatus 200 starts from the captured image. A face area is detected (S2030). Then, the face authentication unit 240 of the face detection apparatus 200 performs face authentication on the face included in the captured video (S2040), and the result of face authentication (permission ID information on which face authentication was successful) is entered / exited by the management apparatus 300. (S2050).

  Upon receipt of such notification, the entrance / exit management device 300 causes the ID authentication necessity determination unit 340 to increase the number of successful face authentications by 1 for the authorization ID information for which face authentication has been successful, and the number of successful face authentications exceeds a predetermined value. It is determined whether or not there is (S2060), and if it is equal to or greater than the predetermined value, the ID authentication unit 350 is instructed to perform ID authentication (S2070). Upon receiving such an instruction, the ID authentication unit 350 requests the card reader 141 to obtain a notification for prompting an IC card operation and ID information (S2080). As a result, the IC card operation is performed by the person who received the notification (S2090), and the ID information of the IC card 121 is notified to the ID authentication unit 350 (S2100). Then, the ID authentication unit 350 performs ID authentication on the acquired ID information (S2110), and when the ID authentication is successful, outputs authentication success information to the door control unit 360 (S2120), and temporarily opens the door 140. Release (S2130).

  In this way, the entrance / exit management system 100 increases the number of face authentication successes each time face authentication succeeds, and performs ID authentication while the number of face authentication successes is less than a predetermined value.

  Each time a person passes through the entrance of the management target area 110, face authentication processing, increase in the number of successful face authentications, and determination processing are performed in the same manner as in steps S2010 to S2060 described above (S2210 to S2260). Then, the ID authentication necessity determination unit 340 of the entrance / exit management device 300 outputs authentication success information to the door control unit 360 without instructing the execution of ID authentication when the number of successful face authentications is equal to or greater than a predetermined value. (S2270), the door 140 is temporarily opened (S2280).

  By such an operation, the entrance / exit management system 100 omits ID authentication for an authorized person who has succeeded in face authentication for a predetermined number of times or more, and allows entry into the management target area 110 in other cases. Can perform ID authentication.

<Effects of the present embodiment>
As described above, the entrance / exit management system 100 according to the present embodiment includes the entrance / exit management device 300. The entrance / exit management device 300 determines, based on the face, whether or not the person located at the entrance 130 of the management target area 110 is an authorized person who is authorized to enter the management target area 110. Whether the person located at the entrance 130 is an authorized person based on the ID information of the face information obtaining unit 320 that obtains the result of face authentication and the IC card 121 (terminal) possessed by the person located at the entrance And an ID authentication unit 350 that performs ID authentication. Then, the entrance / exit management apparatus 300 corresponds to the person located at the entrance 130, the number of successful face authentications, and the number of successful face authentications counted for each authorized person is equal to or greater than a predetermined value, and The door control unit 360 temporarily opens the entrance when at least one of the conditions that the ID authentication is successful is satisfied.

  Thereby, the entrance / exit management system 100 according to the present embodiment may notify the administrator when the non-authorized person enters the management target area 110 or keep the door 140 closed. It is possible to achieve highly reliable entrance / exit management while reducing the number of times of ID authentication.

<Modification of the present embodiment>
Note that the ID authentication necessity determination unit 340 may include the number of successful face authentications in a predetermined area including an area other than the entrance 130 in the number of successful face authentications. For example, the number of successful face authentications may be a value obtained by adding together the number of successful face authentications at the entrance 130 and the number of successful face authentications in the management target area 110 for the same authorized person. Further, for example, the number of successful face authentications may include the number of successful face authentications performed together with ID authentication in places other than the management target area 110 in the number of successful face authentications.

  Thereby, it is possible to make ID authentication unnecessary earlier for an authorized person who can perform face authentication with high accuracy.

  Further, the ID authentication necessity determination unit 340 may vary the predetermined value of the number of successful face authentications, which is a criterion for determining whether or not to perform ID authentication, for each authorized person. Further, the ID authentication necessity determination unit 340 may perform ID authentication depending on the authorized person regardless of the number of successful face authentications.

  In addition, for an authorized person who has come to the entrance 130 without having an IC card because he / she can pass through face authentication, face authentication may fail even though he / she is an authorized person. Therefore, in preparation for such a situation, the entrance / exit management system 100 may include a number input interface in the vicinity of the door 140 and accept manual input of ID information from the number input interface.

  Further, the terminal that holds the ID information assigned to the authorized person is not limited to the IC card. Such a terminal may be various portable terminals such as a mobile phone. Such a terminal may output ID information by wireless communication other than radio waves such as light and sound, or may output ID information by wired communication using a connector.

  In addition, the entrance / exit management device 300 notifies the suspicious person at the entrance 130 of the management target area 110 when the ID information of the authorized person is not acquired even though the captured image includes a face image. Information may be transmitted to the personal computer 400.

  In addition, the entrance / exit management system 100 may arrange the same equipment as the entrance 130 at the exit of the management target area 110 and perform door opening / closing control for an authorized person who wishes to leave the management target area 110.

  Moreover, the part of the entrance / exit management device 300 may be physically separated from other parts of the entrance / exit management device 300. In this case, each separated part needs to have a communication circuit for communicating with each other.

  Further, at least a part of the face detection apparatus 200 and at least a part of the entrance / exit management apparatus 300 may be configured integrally. For example, the face information acquisition unit 320 of the entrance / exit management device 300 has the functions of the face detection unit 230 and the face authentication unit 240 of the face detection device 200, and acquires face information by performing face detection and face recognition. Also good.
