ID DECISION DEVICE

PROBLEM TO BE SOLVED: To provide an ID decision device where an ID is difficult to be copied. SOLUTION: The ID decision device (10) is provided with; an interrogator (11) for radiating an electric wave to a reflector (20); a plurality of detectors (12a to 12d) for detecting reflection intensity of t...

Summary:PROBLEM TO BE SOLVED: To provide an ID decision device where an ID is difficult to be copied. SOLUTION: The ID decision device (10) is provided with; an interrogator (11) for radiating an electric wave to a reflector (20); a plurality of detectors (12a to 12d) for detecting reflection intensity of the electric wave reflected by the reflector (20); a correlation value calculation means (13) for finding a correlation value between reflection intensities detected by the plurality of detectors (12a to 12d); an ID storage means (14) for preliminarily storing the correlation value between reflection intensities detected when radiating an electric wave to the reflector (20), as an ID of the reflector (20); and an ID decision means (15) for deciding coincidence or non-coincidence between the correlation value obtained by the correlation value calculation means (13) and the ID stored in the ID storage means (14).
