在本文中，提出了两个无芯片的解决方案，致力于制造产品的认证。一个设备在RF域中工作，而另一个使用太赫兹（THz）波。无芯片RFID的概念被扩展到身份验证，其中每个标签必须呈现一个唯一的签名，即使有人试图复制标签也无法复制。这两种方法都使用电磁（EM）波作为对物品进行非侵入性和非破坏性认证的工具。结果表明，它是可能的歧视RF，分别太赫兹，从设备的几何参数的差异是小到几十微米，分别在太赫兹域中的几个微米获得的签名。
In this paper, two chipless solutions dedicated to the authentication of manufactured products are proposed. One device is operating in the RF domain while the other used terahertz (THz) waves. The concept of chipless RFID is extended to authentication where each tag has to present a unique signature that can never be reproduced even if someone try to copy the tag. Both approaches use Electromagnetic (EM) wave as a tool for non-invasive and non-destructive authentication of items. The results show that it is possible to discriminate RF, respectively THz, signatures obtained from devices whose differences of geometrical parameters are as small as tens of micrometers, respectively several micrometers in the THz domain.
