<p><P>PROBLEM TO BE SOLVED: To solve a problem wherein a managing data volume increases along with an increase of kinds of IC tags, when managing data format information in every IC tag in a host computer side, and a problem wherein a processing time increases for authentication processing when limiting reading in the IC tag. <P>SOLUTION: A terminal of the IC tag generates data storage information, divides a data, based on the generated data storage information, and writes the divided data in together with the data storage information. Then, the terminal acquires the data, based on the data storage information acquired from the IC tag, and restores an original data. An internal data of the IC tag is correctly acquired thereby without managing a data format in each IC tag. A meaning of the internal data of the IC tag is also prevented from being analogized, by changing dynamically an area of storing the data in each IC tag. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
