Authentication Using Metallic Inkjet-Printed Chipless RFID Tags
Résumé
A high-level (i.e., in terms of security) authentication method is proposed in this paper, where the chipless radio frequency identification (RFID) is extended to the chipless authentication. The proposed method is based on low cost inkjet-printed square check patterned chipless tags, whose design is explicitly optimized keeping the randomness inherent to the inkjet printing process in view. These optimized chipless tags are very difficult to duplicate, as their unique backscattered electromagnetic (EM) responses depend on the proximate coupling among the possible separated squares, which is happened naturally due to the randomness in inkjet printing. The performance of the proposed method is analyzed by a low cost impulse radio (IR) ultrawideband (UWB) chipless RFID reader as well as by the highly accurate vector network analyzer (VNA) based chipless RFID reader. The achieved probability of error is comparable to the various fingerprint evaluation campaigns found in the literature.
