Description

  The present invention relates to an entrance / exit management system for managing entrance / exit persons in a management area.

  Conventionally, an entrance / exit management system using a reader such as a non-contact IC card storing identification information has been used as a system for managing the entrance / exit persons in a management area (see, for example, Patent Document 1). Persons who are allowed to enter and leave the room (hereinafter referred to as registrants) possess a non-contact IC card, and enter the non-contact IC card by placing it in a reader provided at the entrance / exit of the management area. Exit is allowed. By using this type of entrance / exit management system, it is possible to ensure the security of the management area.

  By the way, in recent years, an entrance / exit management system using an authentication device for authenticating biometric information such as a registrant's face, fingerprint, iris and voice has been proposed. The authentication apparatus reads the biometric information of the person entering and leaving the room and compares it with biometric information registered in advance to determine whether the person who entered and leaves the room is a registered person. In an entrance / exit management system using this type of authentication device, it is possible to ensure a higher level of security than a system using a conventional reader that reads identification information recorded on a non-contact IC card. However, since there are many expensive authentication devices in general, this is a factor in increasing the cost when installing an entrance / exit management system. In addition, since there are many expensive authentication devices, there are many situations where a user who has already used a conventional system cannot install the authentication device.

It is a block diagram which shows the function structure of the entrance / exit management system of FIG. It is a block diagram which shows the function structure of the management control apparatus of FIG. FIG. 3 shows a sequence diagram when the entrance / exit management system of FIG. 2 opens the door when the second mode is set.

  Hereinafter, embodiments of an entrance / exit management system according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing an overview of an entrance / exit management system according to an embodiment of the present invention. The entrance / exit management system in FIG. 1 is a system for managing the entrance / exit persons in the management area A1. The management area A1 is, for example, a space formed on the floor of a building such as a building. A door 13 is provided at the entrance / exit of the management area A1. The door 13 is normally closed and is opened only when a person permitted to enter and leave the management area A1 passes. A reader 12 for a non-contact IC card is installed inside and outside the management area A1 with the door 13 in between. A person who intends to enter the management area A1 or leave the management area A1 for his / her own authentication (hereinafter referred to as a person to be authenticated) holds the portable terminal 11 held by the reader 12.

  FIG. 2 is a block diagram showing a functional configuration of an entrance / exit management system according to an embodiment of the present invention. The entrance / exit management system in FIG. 2 includes a mobile terminal 11, a reading device 12, a door 13, and a management control device 14.

  The mobile terminal 11 is a mobile phone or the like, for example, and is possessed by the person to be authenticated. The mobile terminal 11 includes a photographing unit 111, a non-contact communication unit 112, a CPU (Central Processing Unit) 113, a memory 114, an antenna 115, a reception unit 116, and an insertion unit 117. The imaging unit 111 is a camera, for example, and acquires a face image of the person to be authenticated. The photographing unit 111 outputs the acquired face image to the CPU 113.

  The CPU 113 controls the operation of the mobile terminal 11. The CPU 113 performs communication connection with a distribution server (not shown) via the antenna 115 and the receiving unit 116, and downloads an application program for performing face authentication from a predetermined website. Then, the CPU 113 records the downloaded application program in the memory 114 in advance. The user of the portable terminal 11 captures his / her face image at the time of initial setting of the application program. The CPU 113 records the face image taken at the initial setting in the memory 114 as a registered face image. Note that the face authentication program may be installed via the insertion unit 117 from a removable medium in which the face authentication program is recorded.

  When the user executes a face authentication application program, the CPU 113 starts face authentication processing. The CPU 113 requests the user to shoot a face image. The CPU 113 receives the face image from the photographing unit 111 and collates this face image with the registered face image recorded in the memory 114. When the face image from the imaging unit 111 matches the registered face image, the CPU 113 writes a flag indicating successful face authentication in the non-contact IC chip 1121 of the non-contact communication unit 112. Note that the CPU 113 deletes the flag when a preset time has elapsed.

  The non-contact communication unit 112 includes a non-contact IC chip 1121 connected to the CPU 113 and a non-contact communication antenna 1122 connected to the non-contact IC chip 1121. The non-contact IC chip 1121 and the antenna 1122 comply with the standard of a non-contact IC card that performs two-way communication using a 13.56 MHz frequency band in the vicinity of the reader 12, for example. In the non-contact IC chip 1121, data permitting entry / exit is recorded. In the non-contact IC chip 1121, an area in which a flag indicating that the face authentication is successful is set in advance.

  The reading device 12 performs bidirectional communication with the non-contact communication unit 112 of the mobile terminal 11 possessed by the person to be approved. The reading device 12 reads data recorded on the non-contact IC chip 1121 by performing bidirectional communication. The reading device 12 outputs the read data to the management control device 14.

  The management control device 14 performs the process shown in FIG. That is, the management control device 14 includes a first determination unit 141, a second determination unit 142, an opening / closing control unit 143, and a switching control unit 144.

  The first determination unit 141 determines whether or not the reading device 12 has read data allowing entry / exit. The first determination unit 141 outputs a first determination signal to the opening / closing control unit 143 when it is determined that the data permitting entry / exit is read.

  The second determination unit 142 determines whether the reading device 12 has read a flag indicating that face authentication has been successful. The second determination unit 142 outputs a second determination signal to the open / close control unit 143 when it is determined that the flag indicating that the face authentication is successful has been read.

  The opening / closing control unit 143 controls the opening / closing of the door 13 in the first mode and the second mode. When the first mode is set, the opening / closing control unit 143 opens the door 13 in accordance with the first determination signal from the first determination unit 141. When the second mode is set, the opening / closing control unit 143 responds to the first determination signal from the first determination unit 141 and the second determination signal from the second determination unit 142. Open the door 13.

  The switching control unit 144 switches between the first mode and the second mode in the opening / closing control unit 143. For example, the switching control unit 144 sets the first mode at the normal time. At this time, the person to be authenticated can enter and leave the room only by holding the portable terminal 11 over the reading device 12 and reading the data indicating permission of entry and exit recorded in the non-contact IC chip 1121. On the other hand, the switching control unit 144 sets the security to the second mode of higher priority when an unauthorized entry / exit such as companion is detected. At this time, the person to be authenticated cannot enter / exit in the management area A1 unless the reading device 12 reads the flag indicating that the face authentication is successful in addition to the data indicating permission of entry / exit. Further, when the risk of unauthorized entry / exit is released, the switching control unit 144 switches the security to the normal first mode.

  Next, the entrance / exit management operation by the entrance / exit management system configured as described above will be specifically described.

  FIG. 4 shows a sequence diagram when the entrance / exit management system according to the embodiment of the present invention opens the door 13 when the second mode is set.

  The person to be authenticated inputs an application program activation instruction to the portable terminal 11 when entering or leaving the management area A1. When receiving the activation instruction from the authentication subject, the portable terminal 11 activates the application program recorded in the memory 114 (sequence S41). Thereby, face authentication is started (sequence S42). The portable terminal 11 requests the person to be authenticated to take a face image. The CPU 113 collates the captured face image with the registered face image recorded in the memory 114. If the photographed face image matches the registered face image, it is assumed that the face authentication is successful (sequence S43), and a flag indicating that the face authentication is successful is written in the non-contact IC chip 1121 (sequence S44).

  Then, the person to be authenticated holds the portable terminal 11 over the reading device 12 to cause bidirectional communication between the non-contact communication unit 112 and the reading device 12. As a result, the reading device 12 reads data recorded in the non-contact IC chip 1121.

  The management control device 14 acquires the data read by the reading device 12, and detects data permitting entry / exit and a flag indicating that face authentication has been successful (sequence S45). When the management control device 14 detects the data permitting entry / exit and the flag indicating that the face authentication is successful, the management control device 14 opens the door 13 (sequence S46).

  Note that the flag written in the non-contact IC chip 1121 is erased when a predetermined time elapses. For this reason, after a sequence S44, if a predetermined time elapses until the portable terminal 11 is held over the reading device 12, the management control device 14 does not detect the flag and the door 13 does not open.

  As described above, in the above-described embodiment, face authentication is performed using the photographing function of the mobile terminal 11. If the face authentication is successful, a flag indicating success is written in the non-contact IC chip 1121. Then, the portable terminal 11 in which the flag is written is held over the reading device 12 to permit entry into and exit from the management area A1. This makes it possible to perform face authentication using the non-contact IC card reader 12. That is, an expensive dedicated device for face authentication is not required. In addition, it is possible to add a face authentication function using an existing entrance / exit management system without requiring additional equipment.

  In the above embodiment, the first mode and the second mode are switched according to the security state. That is, since it can be set that face authentication is required only when there is an unauthorized entry / exit, face authentication is not always required at the time of entry / exit. As a result, during normal security, an unnecessary burden is not imposed on the person to be authenticated.

  In the above embodiment, the flag written to the non-contact IC chip 1121 is set to be erased after a predetermined time has elapsed. For this reason, the person to be authenticated cannot use the flag obtained in the previous face authentication. When face authentication is required, the person to be authenticated must always shoot his / her face image and perform face authentication. Don't be. This makes it possible to ensure a higher level of security.

  Therefore, according to the entrance / exit management system according to the present embodiment, the entrance / exit can be managed by using the existing equipment and authenticating the biometric information of the registrant at low cost.

  In the above embodiment, the door 13 is opened by the opening / closing control unit 143 when a predetermined condition is satisfied. However, the present invention is not limited to this. For example, when the door 13 is always locked and a predetermined condition is satisfied, even when the door 13 is unlocked by the opening / closing control unit 143, the same operation can be performed.

  Furthermore, the present invention can be embodied by modifying the constituent elements without departing from the spirit of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment.
