Search information providing device, search information providing system, search information providing method, and program recording medium

A search information providing system comprising:

• a search information providing device;
• and
• a fingerprint capturing device,
• wherein the search information providing device includes:
• at least one processor configured to:
• collate an image of a fingerprint of a person in a captured image of a fingerprint mark of the person left on a handrail member with an image of a fingerprint of a search target person that is given in advance, the handrail member circulating in a circulation path passing through an outward part and a return part, the outward part being a part of the circulation path to assist the person while moving along with movement of a conveyance member that conveys the person by moving from an entrance toward an exit, the return part being a part of the circulation path to move in a direction from the exit toward the entrance;
• and
• when the image of the fingerprint of the person on the handrail member matches the image of the fingerprint of the search target person, output, to a predetermined reporting destination, information indicating that the search target person has been detected,
• wherein the fingerprint capturing device is configured to capture the fingerprint mark of the person left on the handrail member at the return part of the circulation path and supplies the image of the fingerprint of the person to the search information providing device,
• wherein the search information providing system further includes:
• an adhesion device configured to cause a luminescent agent for causing the fingerprint mark of the person in the handrail member to become luminescent to adhere to the handrail member at a part of the circulation path nearer than a part of the circulation path captured by the fingerprint capturing device;
• an irradiation device configured to irradiate a part of the handrail member, the part to be captured by the fingerprint capturing device, with light that causes the luminescent agent to become luminescent;
• and
• a removal device configured to remove the fingerprint mark of the person and the luminescent agent left on the handrail member, at a part after passing through the part of the circulation path captured by the fingerprint capturing device.
