Abstract: A preliminary image is captured that includes parts of an authentication target person. Main authentication targets are determined. The main authentication targets are those parts that each have an acceptable image-capturing state. A single image-capturing device can then be controlled to successively capture images of the main authentication parts of the authentication target person that have been determined with different settings. These images of the main authentication parts that have been captured can then be output. For instance, authentication of the target person may be performed using authentication data for each main authentication part, where such authentication is successfully when authentication for all the main authentication parts is successful.

Abstract: A delivery management system according to an aspect of the present disclosure includes: at least one memory configured to store instructions, and at least one processor configured to execute the instructions to detect placement of a delivery item at a placement location, and generate a verification image obtained by photographing the placement location when the placement is detected.

Abstract: A payment processing system according to an aspect of the present disclosure includes: at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: associate a plurality of customers; specify a product acquired by each of the plurality of customers in a store; and perform at least one of: processing of collective payment by a customer who is a payer among the plurality of customers when it has been determined that all of the plurality of customers have left the store, for products acquired by the plurality of customers, or processing of separate payment by the customer who is the payer when it has been determined that each of the plurality of customers has left the store, for products acquired by the customer.

Abstract: The authentication data generation device controls a single image-taking device to take images of a plurality of authentication parts of the authentication target person with different settings. Then, the authentication data generation device outputs taken images of the plurality of authentication parts obtained by the image-taking as authentication data for the authentication parts.
