Abstract: An authentication control apparatus (10) includes: a biometric information acquisition unit (11) that acquires biometric information of a pedestrian on a predetermined passage in which a plurality of light emitting elements are embedded from a captured image of the pedestrian; an authentication control unit (12) that acquires a biometric authentication result obtained using the acquired biometric information and biometric information of a plurality of persons; a position specification unit (13) that specifies a position of the pedestrian on the passage by analyzing the captured image; and a display control unit (14) that performs display control related to the biometric authentication result for the light emitting element corresponding to a light emission target region including the specified position.

Abstract: An authentication control apparatus (10) includes: an image acquisition unit (11) that acquires an image obtained by imaging a body including a face of an authentication target person; an authentication control unit (12) that acquires a face authentication result obtained using face feature information of a plurality of persons and face feature information extracted from the image; a body surface temperature acquisition unit (13) that acquires a body surface temperature measured from the authentication target person; a decision unit (14) that decides a display mode associated to a combination of the face authentication result and the body surface temperature; and an output unit (15) that outputs the image to a predetermined display device according to the decided display mode.

Abstract: A communication terminal (100) includes a type identifying unit (102) that identifies a type of user-to-user communication means corresponding to a user's operation which is detected by an operation detection unit (101), a data acquisition unit (103) that acquires communication media data of a user of the communication terminal itself, corresponding to the identified type of user-to-user communication means, and a transmission unit (104) that transmits type request information indicating the type of user-to-user communication means and the communication media data to a partner communication terminal, and the type identifying unit (102) determines a range of types of user-to-user communication means to which switching is allowed from a type of current user-to-user communication means, in accordance with a status of response from the partner communication terminal with respect to the type request information transmitted to the partner communication terminal.
