    • PROBLEM TO BE SOLVED: To identify a physical object having random characteristics by using a memory tag. SOLUTION: A physical object, which has a base medium such as a paper sheet or the like and a plurality of memory tags embedded in or attached to the base medium, is provided. The memory tags store at least a pair of measurement/position data including the results of measurement of characteristics which are independent on the position of the base medium originally relating to the tags and a position in or on the object to which the measurement is made. Favorably, the pair of measurement/position data is digitally signed and stored in coded form. It can be checked whether the base medium is original by checking whether the result of the measurement included in the pair of data thus read accords with the result of the present measurement at an indicated position of the base medium. A device which originally writes the pair of data to the memory tags is provided, and a device which executes checking operations by using the pair of data is also provided.

    • 要解决的问题:通过使用存储器标签来识别具有随机特性的物理对象。 提供了一种物理物体,其具有诸如纸张等基础介质和嵌入或附着到基底介质上的多个存储器标签。 存储标签存储至少一对测量/位置数据,包括独立于原始与标签相关的基本介质的位置的特性的测量结果以及进行测量的对象中的位置。 有利的是,该对测量/位置数据被数字签名并以编码形式存储。 通过检查包含在这样读出的数据对中的测量结果是否与基本介质的指示位置处的本测量结果一致,可以检查基本介质是否是原始的。 提供了一种将该对数据写入存储器标签的装置,并且还提供了通过使用该对数据执行检查操作的装置。 版权所有(C)2006,JPO&NCIPI
