1. An information processing system comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to:
store a first pair consisting of face information of a user and re-identification information used for re-identification of the user in association with each other;
acquire, after acquiring the first pair, a second pair consisting of the face information and the re-identification information of a target user;
perform determination of whether or not the first pair and the second pair match by comparing the first pair with the second pair;
output information indicating that the target user is performing spoofing when having determined that the first pair and the second pair do not match; and
perform face verification of the target user in a case when having determined that the first pair and the second pair match.
