Abstract: An operation management system (100) includes a server apparatus (102) and an operation management apparatus (103). The operation management system (100) includes: a reservation acceptance unit (111) acquiring reservation information including biometric information of a user making a boarding reservation for a vehicle, and a boarding point; a boarding information acquisition unit (120) acquiring boarding information including biometric information of the user generated by a camera (103) equipped on the vehicle and boarding place information indicating the boarding point; and an authentication unit (113) determining whether there is a match of biometric information and a boarding point that are included in each piece of the reservation information and the boarding information.

Abstract: The image acquisition unit acquires a body image generated by capturing an image of a body of a target person and a code image generated by capturing an image of a code recording medium. The code recording medium includes a code symbol that can be visually recognized and in which embedded information including biometric information for registration of the target person and identification information on the target person are recorded. The embedded information acquisition unit acquires the embedded information from the code image. The authentication unit executes biometric authentication by collating the biometric information for registration included in the embedded information with biometric information for authentication generated based on the body image. The notification unit notifies a management apparatus of the identification information on the target person when the biometric authentication has been successful.

Abstract: The image acquisition unit acquires a body image generated by capturing an image of a body of a target person when a target person is in a position away from an imaging unit by a first distance and acquires a code image generated by capturing an image of a code recording medium carried by the target person when the target person is in a position away from the imaging unit by a second distance shorter than the first distance. The authentication information generation unit starts processing for generating biometric information for authentication of the target person from the body image in accordance with the acquisition of the body image of the target person. The embedded information acquisition unit acquires embedded information from the code image. The authentication unit executes biometric authentication by collating biometric information for authentication with biometric information for registration included in the embedded information.

Abstract: A congestion degree determination apparatus (2000) acquires a captured image (50) generated by an in-vehicle camera that captures an inside of a target vehicle. The congestion degree determination apparatus (2000) determines, for each of persons (30) present in the target vehicle, an area (20) in which the person (30) is positioned out of a plurality of areas (20) in the target vehicle using the captured image (50). The congestion degree determination apparatus (2000) determines the congestion degree of the target vehicle using the number of the persons (30) positioned in each of two or more of the areas (20).

Abstract: A display control method includes: acquiring information indicating a contact point of an attendant in a train from a management device storing the information indicating the contact point of the attendant in the train; and transmitting information for causing a display device in the train to display a two-dimensional code based on the acquired information.
