Abstract: An accounting system according to the present invention include: an information display device including a first memory; and at least one first processor coupled to the first memory. The first processor performs first operations. The first operations includes: causing a first camera to image a person, and causes a display to display a code based on physical characteristics peculiar to the imaged person. An information processing device includes a second memory; and at least one second processor coupled to the second memory. The second processor performs second operations. The second operations includes: causing a second camera to image the code displayed by the information display device, acquiring accounting information of the person using the imaged code, and executing accounting processing using the accounting information.

Abstract: The disclosure is inputting a first image captured an image of an authentication target; inputting a second image captured an image of a right eye or a left eye of the target; determining whether the second image is of a left eye or a right eye of the target based on information including the first image, and outputting a determination result as left/right information in association with the second image; detecting an overlap between a region including the second image and a predetermined region in the first image; calculating a verification score by comparing characteristic information that are related to the left/right information with iris characteristic information calculated from the second image, and calculating a first weighted verification score obtained by weighting the verification score with a detection result; and authenticating a target in the second image based on the first weighted verification score, and outputting an authentication result.

Abstract: An authentication device includes an image acquisition unit, an identification unit, and an authentication unit. The image acquisition unit acquires an image of an eye of a subject. The identification unit identifies the colored pattern of a colored contact lens worn by the subject by comparing a reference image with the image of the eye. The authentication unit identifies the subject, using a feature in a region other than a colored region of the colored pattern in the iris region of the eye.
