Abstract

An entry/exit management system includes: an authentication unit that performs image authentication of a user who passes through a specific area; an attribute acquisition unit that obtains attribute information about a first user when there are the first user who has succeeded in the image authentication and a second user who has failed in the image authentication; a determination unit that determines an allowable number of people who can accompany the first user, on the basis of the attribute information; and a permission unit that permits the second user to pass through the specific area together with the first user, when the number of the second users is less than or equal to the allowable number of people.

Claims (9)

1 . An entry/exit management system comprising: at least one memory that is configured to store instructions; and at least one processor that is configured to execute the instructions to: perform authentication of a user who passes through a specific area; acquire attribute information about a first user who has succeeded in the authentication determine an allowable number of people who can accompany the first user, on the basis of the attribute information; permit the second user to pass through the specific area together with the first user, when the number of the second users is less than or equal to the allowable number of people; and present an image of the second user to the first user when the number of the second users is less than or equal to the allowable number of people, and permit the second user to pass through the specific area, when the first user permits the second user included in the image as an accompanying person.
2 . The entry/exit management system according to claim 1 , wherein the at least one processor is configured to execute the instructions to: determine whether or not there is a relationship between the first user and the second user; and permit the second user to pass through the specific area, when there is a relationship between the first user and the second user.
3 . The entry/exit management system according to claim 1 , wherein the at least one processor is configured to execute the instructions to change the allowable number of people of the first user, on the basis of an input from the first user.
4 . The entry/exit management system according to claim 1 , wherein the at least one processor is configured to execute the instructions to: calculate a total allowable number of people by summing up the allowable number of people that is determined for each of a plurality of first users, when there are the plurality of the first users; and permit the second user to pass through the specific area, when the number of the second users is less than or equal to the total allowable number of people.
5 . The entry/exit management system according to claim 1 , wherein the at least one processor is configured to execute the instructions to: obtain depth information about the user; generate a silhouette image of the user on the basis of the depth information; and output the silhouette image.
6 . The entry/exit management system according to claim 5 , wherein the at least one processor is configured to execute the instructions to: generate guidance information for guiding the user; and output the guidance information together with the silhouette image.
7 . The entry/exit management system according to claim 1 , wherein the at least one processor is configured to execute the instructions to: extract a feature quantity from an image of the user; generate a first conversion key; convert the extracted feature quantity by using the first conversion key and generates first conversion information; transmit the first conversion key and the first conversion information; store a registered feature quantity that is a feature quantity of a registered user; convert the registered feature quantity by using the first conversion key and generates second conversion information; collate/verify the first conversion information with the second conversion information; generate a second conversion key when collation/verification is successful; convert the registered feature quantity by using the second conversion key and generates third conversion information; transmit the second conversion key and the third conversion information, to the first authentication apparatus, apparatus; store the second conversion key and the third conversion information; convert a newly extracted feature quantity by using the second conversion key and generates fourth conversion information; and collate/verify the fourth conversion information with the third conversion information.
8 . An entry/exit management method comprising: performing authentication of a user who passes through a specific area; acquiring attribute information about a first user who has succeeded in the authentication; determining an allowable number of people who can accompany the first user, on the basis of the attribute information; permitting the second user to pass through the specific area together with the first user, when the number of the second users is less than or equal to the allowable number of people; and presenting an image of the second user to the first user when the number of the second users is less than or equal to the allowable number of people, and permit the second user to pass through the specific area, when the first user permits the second user included in the image as an accompanying person.
9 . A non-transitory recording medium on which a computer program that allows a computer to execute an entry/exit management method is recorded, the entry/exit management method comprising: performing authentication of a user who passes through a specific area; acquiring attribute information about a first user who has succeeded in the authentication; determining an allowable number of people who can accompany the first user, on the basis of the attribute information; permitting the second user to pass through the specific area together with the first user, when the number of the second users is less than or equal to the allowable number of people; and presenting an image of the second user to the first user when the number of the second users is less than or equal to the allowable number of people, and permit the second user to pass through the specific area, when the first user permits the second user included in the image as an accompanying person.

Description

This application is a National Stage Entry of PCT/JP2022/000553 filed on Jan. 11, 2022, which claims priority from JP Patent Application 2021-048491 filed on Mar. 23, 2021, the contents of all of which are incorporated herein by reference, in their entirety. TECHNICAL FIELD This disclosure relates to technical fields of an entry/exit management system, an entry/exit management method, and a recording medium that manage entry/exit of a user. BACKGROUND ART A system that performs entry/exit management of a plurality of people is known as this type of system. For example, Patent Literature 1 discloses a technique/technology of detecting tailgating or piggybacking at an entrance of an apartment with automatic locks. Patent Literature 2 discloses a technique/technology of managing the entry/exit of a second registrant who accompanies a first registrant. Patent Literature 3 discloses a technique/technology of permitting the entry of a visitor, by a resident making a tailgating request. As another related technique/technology, for example, Patent Literature 4 discloses a technique/technology of generating a depth map by imaging or photographing a user from a plurality of viewpoints. Patent Literature 5 discloses a technique/technology of extracting contours by comparing edge intensity in a search range.
