    • An IC tag issue management system includes an ID numbering DB which stores an ID and a status of the ID, and an ID history DB which stores the ID, a history number indicating a reuse history of the ID, and a usage history indicated by the history number correlated with each other with each other. The IC tag issue management system numbers the ID with the usage history having a time elapsing from a starting date of the usage history in which the end date is not stored in the ID history DB passing over a predetermined ID-non-reusable period in response to a request for numbering the ID to be written into the IC tag when the unnumbered ID which has not been allocated to the IC tag, and the ID having the status of the ID numbering DB set in the “unused” status do not exist.
    • IC标签问题管理系统包括存储ID和ID的状态的ID编号DB,存储ID的ID历史DB,表示ID的重用历史的历史编号,以及由ID 历史数据彼此相互关联。 IC标签问题管理系统对ID进行编号,使用历史记录具有从使用历史的开始日期开始的时间,其中结束日期未被存储在通过预定的不可重复使用的ID的不可重复使用周期的ID历史DB中 当没有分配给IC标签的未编号的ID和ID编号DB的ID处于“未使用”状态的ID不存在时,将要写入IC标签的ID编号的请求。

    • 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。
