memory in which at least one program is recorded; and
a processor for executing the program,
wherein the program performs
receiving a missing person report which includes attribute information for representing appearance of a missing person and missing situation information including a time and a location at the time of disappearance,
acquiring CCTV video based on the missing situation information,
extracting full-body image candidates assumed to be of the missing person, among full-body images of human objects contained in the acquired CCTV video, based on the attribute information,
receiving a selection for one of the extracted full-body image candidates as a full-body image of the missing person, and
analyzing CCTV video based on the selected full-body image of the missing person, thereby tracking a travel path of the missing person, wherein the program performs:
extracting the full-body images of the respective human objects contained in the acquired CCTV video when extracting the full-body image candidates,
calculating a degree of matching between each of the full-body images and an attribute for representing the appearance of the missing person based on deep-learning, and
selecting a predetermined number of full-body image candidates in descending order of calculated degree of matching.
