<P>PROBLEM TO BE SOLVED: To improve authentication accuracy while protecting personal information. <P>SOLUTION: A face identification information acquisition unit acquires face identification information on a face region recognized from an image containing a face of a participant who is collecting specific information provided in display devices respectively installed at plural locations and is using a display device installed at a location. An identification unit identifies the participant by checking the acquired face identification information of the participant against registration identification information on face regions of pre-registered registrants. An action history information acquisition unit selects the registrants similar to the identified participant as candidates from the registrants and acquires action history information on histories of actions when those candidates collect the specific information. A presentation unit presents the acquired action history information to the participant who is using the display unit. This technology is applicable, e.g., to a digital signage system providing point rally service. <P>COPYRIGHT: (C)2013,JPO&INPIT |
