Abstract
An RFID tag device has a random number generator which generates a random number or a pseudo-random number, an identification information holding unit which holds identification information having a plurality of bits, a noise addition processing unit which generates noise-added identification information by conducting either of reversal from “0” of a bit decided based on the random number generated by the random number generator to “1” or reversal from “1” of the bit to “0”, among a plurality of bits included in the identification information, and a radio communication unit which transmits the noise-added identification information by radio.
