  • Publication number: 20240144762
    Abstract: In a passage management computer program product, acquiring processing of identification information acquires identification information of a user read by a reading unit that is installed in a passage area and that reads the identification information from an authentication medium. Acquiring processing of photographed image acquires a photographed image of the passage area. Among one or more face image regions in the photographed image, specifying processing specifies a face image region of a user who is carrying the authentication medium as a passerby face image. When the passerby face image matches with a pre-stored face image corresponding to the identification information, authenticating processing authenticates the user who is carrying the authentication medium as an authorized person, and when the passerby face image does not match with the pre-stored face image, authenticates the user who is carrying the authentication medium as an unauthorized person.
