Specifically, the face authentication server 300 compares the visitor's face included in the reference image and the visitor's face included in the matching image based on face authentication processing, and determines that they match. If it does, the collation result is "authenticated", and if it is determined that they do not match, the collation result is "non-authenticated". The communication unit 320 transmits the matching result to the control device 50 . The face authentication server 300 is an example of a storage unit that stores a history of matching results.

Here, as face authentication, for example, face authentication based on the positions of facial feature points such as eyes, nose, and mouth is exemplified. Therefore, the feature point positions of the visitor's face included in the reference image are an example of the first information corresponding to the reference image, and the feature point positions of the visitor's face included in the matching image correspond to the matching image. It is an example of the second information.

It should be noted that other authentication methods can be adopted as long as the visitor can be verified. Other authentication methods include, for example, iris authentication, fingerprint authentication, palm print authentication, and vein authentication. In any authentication method, the physical features of the visitor included in the reference image are the first information corresponding to the reference image, and the physical features of the visitor included in the matching image correspond to the matching image. It becomes the second information.

The control device 50 includes, for example, a communication section 51 and a control section 53 .

The control unit 53 is implemented by, for example, a microcomputer or processor. The control unit 53 is an example of a third acquisition unit that acquires the matching result from the face authentication server 300 . Also, the control unit 53 is an example of an output unit that outputs control information for controlling the first gate 110 and the second gate 120 from the communication unit 51 . Specifically, when communication unit 51 receives an unlocking instruction for first gate 110 transmitted from intercom base unit 60a, control unit 53 creates open information as control information for controlling first gate 110. and output. Accordingly, after the open information is transmitted from the communication unit 51 to the communication unit 27 of the first intercom entrance device 20 , the open information is transmitted from the communication unit 27 to the first gate 110 .

Also, the control unit 53 creates and outputs control information for controlling the second gate 120 based on the acquired collation result. For example, when the collation result indicates authentication, the control unit 53 creates and outputs opening information for opening the second gate 120 as control information. Accordingly, after the open information is transmitted from the communication unit 51 to the communication unit 47 of the second intercom entrance device 40 , the open information is transmitted from the communication unit 47 to the second gate 120 .

Further, the control unit 53 creates notification information for notifying information about the matching result as control information based on the matching result, and outputs the notification information from the communication unit 51 to the intercom base unit 60a. Specifically, for example, when the collation result indicates authentication, control unit 53 creates notification information indicating authentication as control information, and outputs the control information to intercom master device 60a.

Control unit 53 is an example of a registration unit that temporarily registers a reference image in face authentication server 300 upon receiving a registration instruction from intercom master device 60a. That is, control unit 53 determines to temporarily register the reference image in face authentication server 300 based on the input to intercom master device 60a. After the determination, control unit 53 outputs a reference image registration instruction to face authentication server 300 from communication unit 51 .

The input reception unit 65 is implemented by a touch panel, hardware buttons, or the like. Specifically, input accepting portion 65 accepts an unlocking instruction for first gate 110 . Further, the input reception unit 65 receives a registration instruction for the reference image. The input reception unit 65 also receives the expiration date of the registered reference image together with the reception instruction. The input reception unit 65 is an example of a time limit setting unit that sets an expiration date for the registered reference image. Here, the term of validity is composed of at least one of a predetermined period of time and a predetermined number of verifications. The predetermined period is the period after registration, and can be set in units of days, weeks, or minutes, for example. Also, the predetermined number of collation times means the number of times the reference image has been collated after being registered. A common expiration date can be set for a plurality of registered reference images, or an expiration date can be set individually. If the expiration date is set in common, it is possible to reduce the trouble of setting the expiration date. On the other hand, when the expiration date is individually set, an appropriate expiration date can be set for each reference image.

Based on the operation instruction received via the communication unit 61, the control unit 62 causes the sound output unit 64b to output a ringing tone. Further, the control unit 62 causes the display unit 63 to display the reference image received via the communication unit 61 . When the communication unit 61 receives the notification information based on the collation result, the control unit 62 causes the display unit 63 to display the notification information. The controller 62 is implemented by, for example, a microcomputer or processor.

The calling unit 64 is a device for communicating with the visitor who performed the calling operation via the first intercom entrance device 20 . The call unit 64 has a sound pickup unit 64a that picks up the sound emitted by the resident, and a sound output unit 64b that outputs the signal transmitted from the first intercom entrance device 20 via the control device 50 as sound. . The sound pickup unit 64a is implemented by, for example, a microphone. Also, the sound output unit 64b is implemented by, for example, a speaker.
