A new clone detection approach in RFID-enabled supply chains

We propose a new method for detecting cloned tags in RFID-enabled supply chains, aiming to overcome the deficiencies of the existing clone detection techniques in RFID supply chains, caused in partial by the dynamic changes and incidents in radio frequency identification (RFID) supply chains. We first provide a formal (categorical) model for the activities in RFID supply chains, and then present a new cloned tag detection technique by adding a verification bit into tag events, which is followed by some clone detection examples. Next, we compare the performance of the newly proposed clone detection technique against Zanetti's clone detection mechanism by conducting relevant experiments, and finally discuss the related work in the literature. The results of the experiments demonstrate that our proposed mechanism is effective, reasonable, and outperforms Zanetti's work in terms of hit rate.
