摘要：
To prevent privacy invasion performed according to a proper identifier which has been read.A pseudo-RFID transmission device for transmitting a pseudo identifier (RFID) for disturbing an invader is provided to an individual user. When an RFID transmission instruction is received from a tag reader (SAI), a variable type pseudo RFID different from the one which has been transmitted previously is transmitted (SA3 to SA5) and different RFID is transmitted each time for the same person. The respective pseudo RFID transmission devices are grouped into a plurality of types, so that the pseudo RFID transmission devices belonging to the same group transmit their variable type pseudo RFID while increasing the possibility to transmit common pseudo RFID accorded with one another. An area is specified for each group and the respective pseudo RFID transmission devices are provided to individual users, so that the same RFID may be transmitted for the same person.
