Abstract: A person specifying device includes an authentication unit configured to acquire a captured image capturing a person boarding a moving vehicle, to perform a matching determination as to whether or not the person reflected in the captured image matches a pre-registered person, and to generate person-specifying information representing the person determined via the matching determination; and an authentication-interval-updating unit configured to update a time interval for performing the matching determination to be shorter when failing to achieve a success frequency of authentication above a desired value via the matching determination.
