1. An authentication control device comprising:
at least one memory storing instructions, and
at least one processor configured to execute the instructions to;
acquire an image including an authentication object person walking in a monitoring area photographed by a camera for photographing the monitoring area;
cause an authentication device for performing face authentication to perform face authentication of the authentication object person included in the image acquired;
specify a projection area in which a result of the face authentication is projected; and
cause a projection device to project the result of the face authentication on the projection area specified;
extract feature information of a non-face area from the non-face area other than the face of the authentication object person included in the image;
register the feature information of the non-face area extracted and the result of the face authentication in association with each other;
verify the feature information extracted against the feature information registered;
acquire a first image and a second image captured after the first image is captured as the image;
cause the authentication device to perform face authentication of the authentication object person included in the first image;
extract first feature information of the non-face area from the non-face area other than the face of the authentication object person included in the first image, and extract second feature information of the non-face area from the non-face area other than the face of the authentication object person included in the second image;
register the first feature information extracted in association with the result of the face authentication;
verify the second feature information extracted against the first feature information registered; and
cause the projection device to project the result of the face authentication registered on the projection area specified.
