Potential of chipless authentication based on randomness inherent in fabrication process for RF and THz

Abstract : 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.
