Abstract: A ticket issuing system has a processor and a storage with instructions thereon. The storage stores a feature value table that associates and stores feature value data including feature information pertaining to biometric information and a feature ID for identifying the feature value data. The instructions upon execution by the processor, cause the processor to: 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; and issue a ticket on which authentication information that includes the feature ID corresponding to the similar feature value data is recorded.

Abstract: An apparatus including processing circuitry configured to: detect use of a ticket; and grant a token whose ownership can be clarified to an owner of the ticket in response to the detection of the use of the ticket.

Abstract: An information processing server for managing a ticket, including: a server storage unit storing feature quantity data obtainable from biological information and created in advance, feature quantity identification information associated with the feature quantity data, and prescribed data that is identical to prescribed data stored in a determination device for determining a usage validity of a ticket; and a server control unit determining an item of feature quantity data from a piece of biological information on a user who is to use a ticket, determine a piece of feature quantity identification information based on a comparison between the determined item of feature quantity data and items of feature quantity data stored in the server storage unit, generate a code to be attached to the ticket based on an assigned piece of ticket identification information, the determined piece of feature quantity identification information, and the prescribed data, and generate ticket data.
