Server device, system, method for controlling server device, and storage medium

1 . A server device comprising:

at least one processor configured to:

acquire facial information of a person to be authenticated from a terminal;

perform a facial authentication using the facial information of the person to be authenticated and facial information of each of a plurality of users registered in advance;

determine whether the facial authentication is successful, wherein authentication result information of the facial authentication includes the facial information acquired from the terminal and registered facial information of a successful authentication person, the successful authentication person having succeeded in the facial authentication;

based on (i) the facial authentication being successful and (ii) at least one predetermined condition being satisfied, the at least one predetermined condition comprising a condition that is satisfied based on a seat grade corresponding to a predetermined class from among a plurality of classes, transmit the authentication result information to the terminal or a staff terminal used by a staff.

2 . The server device according to claim 1 , wherein the at least one processor

calculates a similarity between the facial information of the person to be authenticated and the facial information of each of the plurality of users registered in advance, and

the at least one predetermined condition further comprises a condition that is satisfied in a case where a similarity having a largest value among a plurality of the calculated similarities is larger than a first threshold and smaller than a second threshold.

3 . The server device according to claim 1 , wherein the at least one processor

calculates a similarity between the facial information of the person to be authenticated and the facial information of each of the plurality of users registered in advance,

calculates a difference between a first similarity having a largest value and a second similarity having a second largest value among a plurality of the calculated similarities, and

the at least one predetermined condition further comprises a condition that is satisfied in a case where the calculated difference is smaller than a predetermined threshold.

4 . The server device according to claim 1 , wherein the at least one processor transmits the authentication result information to the staff terminal when the seat grade of the successful authentication person is a highest rank guest seat.

5 . The server device according to claim 1 , further comprising a database configured to store the facial information of each of the plurality of users.

6 . The server device according to claim 1 , wherein the facial information is a face image or a feature amount extracted from the face image.

7 . The server device according to claim 1 , wherein the at least one processor transmits the authentication result information to the terminal.

8 . A system comprising:

a terminal;

a staff terminal used by a staff; and

a server device according to claim 1 , the server device being connected to the terminal and the staff terminal.

9 . The system according to claim 8 , wherein the staff terminal performs display including the facial information acquired from the terminal and the registered facial information of the successful authentication person.

10 . The system according to claim 9 , wherein the staff terminal acquires whether the staff determines that a different person acceptance has occurred based on the facial information acquired from the terminal and the registered facial information of the successful authentication person.

11 . The system according to claim 10 , wherein when it is determined that the different person acceptance has occurred, the staff terminal instructs the terminal to interrupt a procedure.

12 . A method for controlling a server device, comprising:

acquiring facial information of a person to be authenticated from a terminal;

performing a facial authentication using the facial information of the person to be authenticated and facial information of each of a plurality of users registered in advance;

determining whether the facial authentication is successful, wherein authentication result information of the facial authentication includes the facial information acquired from the terminal and registered facial information of a successful authentication person, the successful authentication person having succeeded in the facial authentication; and

based on (i) the facial authentication being successful and (ii) at least one predetermined condition being satisfied, the at least one predetermined condition comprising a condition that is satisfied based on a seat grade corresponding to a predetermined class from among a plurality of classes, transmitting the authentication result information to the terminal or a staff terminal used by a staff.

13 . A non-transitory computer-readable storage medium storing a program for causing a computer mounted on a server device to execute:

acquiring facial information of a person to be authenticated from a terminal;

performing a facial authentication using the facial information of the person to be authenticated and facial information of each of a plurality of users registered in advance;

determining whether the facial authentication is successful, wherein authentication result information of the facial authentication includes the facial information acquired from the terminal and registered facial information of a successful authentication person, the successful authentication person having succeeded in the facial authentication; and

based on (i) the facial authentication being successful and (ii) at least one predetermined condition being satisfied, the at least one predetermined condition comprising a condition that is satisfied based on a seat grade corresponding to a predetermined class from among a plurality of classes, transmitting the authentication result information to the terminal or a staff terminal used by a staff.

14 . The server device according to claim 1 ,

wherein the facial information acquired from the terminal is a face image acquired from the terminal,

wherein the registered facial information of the successful authentication person is a registered face image of the successful authentication person, and

wherein the authentication result information is for displaying the face image acquired from the terminal and the registered face image of the successful authentication person on a single screen of the staff terminal.

15 . The method according to claim 12 ,

wherein the facial information acquired from the terminal is a face image acquired from the terminal,

wherein the registered facial information of the successful authentication person is a registered face image of the successful authentication person, and

wherein the authentication result information is for displaying the face image acquired from the terminal and the registered face image of the successful authentication person on a single screen of the staff terminal.

16 . The non-transitory computer-readable storage medium according to claim 13 ,

wherein the facial information acquired from the terminal is a face image acquired from the terminal,

wherein the registered facial information of the successful authentication person is a registered face image of the successful authentication person, and

wherein the authentication result information is for displaying the face image acquired from the terminal and the registered face image of the successful authentication person on a single screen of the staff terminal.
