1. An authentication device comprising one or more memories storing instructions and one or more processors configured to execute the instructions to:
detect an authentication target who is moving in a predetermined direction in a video of a predetermined area;
input a first image in which an entire body of the detected target is imaged;
calculate characteristic information from an image of the entire body of the target imaged in the first image, compare the calculated characteristic information with the characteristic information of the entire body stored in first memory that stores characteristic information of entire bodies of one or more targets to be authenticated to execute first authentication, and extract candidate information of the one or more targets from the first memory based on a comparison result;
input a second image in which an iris of a right eye or a left eye of the target who is detected and is moving in the predetermined direction is imaged;
determine whether the second image is of the left eye or the right eye of the target based on information including the first image, and output a determination result in association with the second image as left/right information; and
compare characteristic information of the iris calculated from the second image associated with the left/right information with the characteristic information of one or more irises related to the left/right information and stored in second memory that stores characteristic information of irises of right eyes and left eyes of the one or more targets to be authenticated, calculate a verification score for each target included in the candidate information, execute second authentication on the target imaged in the second image based on the calculated verification score, and output an authentication result.
