    • For making difficult to copy data of a RFID tag, while enabling to detect it when copying the data, easily, but without exerting ill influences upon the existing specification thereof, within the RFID tag 100 is provided a readout exclusive bank, other than banks provided in accordance with the existing specification. RFID identification information is stored into the readout exclusive bank of the RFID tag 100, when the RFID tag 100 is shipped out of a maker. A user who wishes to guarantee properness of UII data produces cryptograph calculation result data through encrypting the RFID identification information and the UII data, when writing the UII data into the RFID tag 100, and stores the cryptograph calculation result data into a USER bank within the RFID tag 100. Other users, who wish to read out the UII data from the RFID tag 100, read out the RFID identification information and the UII data from the RFID tag 10, so as to conduct cryptography calculation thereon, and can make determination on whether the data stored in the RFID tag is proper one or not, by making a check upon coincidence between the calculation result and the calculation result data stored in the RFID tag 100.
    • 为了难以复制RFID标签的数据,虽然能够容易地复制数据时能够对其进行检测,但是对其现有规范没有不利影响,但是在RFID标签100内提供了除了提供的银行之外的读出专用银行 按照现行规范。 当RFID标签100从制造商运出时,RFID识别信息被存储到RFID标签100的读出专用库中。 希望保证UII数据的正确性的用户,当将UII数据写入RFID标签100时,通过加密RFID识别信息和UII数据来产生加密计算结果数据,并将加密计算结果数据存储在用户银行内 RFID标签100。 希望从RFID标签100读取UII数据的其他用户从RFID标签10读出RFID识别信息和UII数据,以便对其进行密码学计算,并且可以确定数据是否存储 通过对存储在RFID标签100中的计算结果和计算结果数据之间的一致性进行检查,在RFID标签中是否适当。
