acquire user feature information pertaining to biometric information of a user of a ticket to be issued;

identify, from among the feature value data stored in the feature value table, similar feature value data for which a similarity with the user feature information satisfies a predetermined criterion to obtain a feature ID corresponding to the similar feature value data;

issue a ticket on which authentication information that includes a ticket ID for identifying a ticket that is issued is recorded; and

record the feature ID corresponding to the similar feature value data in association with the ticket ID.

9. The ticket issuing system according to claim 8 , wherein:

the feature information pertaining to the biometric information is feature information pertaining to an appearance of a face of a person.

10. The ticket issuing system according to claim 9 , wherein:

feature value data stored in the feature value table includes feature information pertaining to an appearance of a non-existent person.

11. The ticket issuing system according to claim 8 , wherein the instructions upon execution by the processor, cause the processor to:

register, in a case where the similar feature value data is not identified, new feature value data for which a similarity with the user feature information satisfies a predetermined criterion in the feature value table.

12. A ticket checking apparatus comprising a processor and a storage with instructions thereon, wherein the storage stores a feature value table that associates and stores feature value data that is feature information pertaining to exemplary biometric information and a feature ID, and

the instructions upon execution by the processor, cause the processor to:

acquire biometric information of a user who uses a ticket;

calculate user feature information with respect to the biometric information of the user;

acquire a target feature ID that is recorded on the ticket;

acquire a reference feature value data associated with the target feature ID by referring to the feature value table;

determine a similarity between the user feature information and the reference feature value data; and

output the result of determination according to the similarity.

13. The ticket checking apparatus according to claim 12 , the instructions upon execution by the processor, cause the processor to:

identify, in a case where the target feature ID is not recorded on the ticket, from among the feature value data stored in the feature value table, similar feature value data for which a similarity with the user feature information satisfies a predetermined criterion to obtain a feature ID corresponding to the similar feature value data; and

record the feature ID corresponding to the similar feature value data in association with information on the ticket.

14. The ticket checking apparatus according to claim 12 , wherein:

the target feature ID is recorded on the ticket in a machine-readable form; and

the instructions upon execution by the processor, cause the processor to read a feature ID which is recorded on the ticket that the user holds to acquire the target feature ID.

15. The ticket checking apparatus according to claim 12 , wherein:

the feature information pertaining to the biometric information is feature information pertaining to an appearance of a face of a person.

16. The ticket checking apparatus according to claim 15 , wherein the instructions upon execution by the processor, cause the processor to

acquire, from an imaging device, a user image that includes a face of the user, and

identify the user appearing in the user image based on a distance from the imaging device to a person appearing in the user image.

17. The ticket checking apparatus according to claim 15 , wherein the instructions upon execution by the processor, cause the processor to:

acquire, from an imaging device, a user image that includes a face of the user and the ticket which the user holds; and

analyze the user image to read the target feature ID which is recorded on the ticket which the user holds.

18. The ticket checking apparatus according to claim 17 , wherein the instructions upon execution by the processor, cause the processor to recognize, in the user image, a face appearing at a predetermined position relative to a face of the ticket as the face of the user; and

calculate feature information pertaining to an appearance of the face of the user.

19. A ticket checking apparatus comprising a processor and a storage with instructions thereon, wherein the storage stores:

a feature value table that associates and stores feature value data that is feature information pertaining to exemplary biometric information and a feature ID; and

a ticket information table that associates and stores a ticket ID for identifying a ticket and the feature ID corresponding to a user of the ticket, and

the instructions upon execution by the processor, cause the processor to:
