Abstract

Traces of RFID-equipped item can be used to detect counterfeits. Nevertheless companies are reluctant to share the necessary traces, since it is unclear what can be inferred from them. In this paper we present a provably secure pattern matching algorithm that can be used for distributed anomaly detection. We improve performance and detection capabilities compared to competing approaches by storing partial, malleable information on the RFID tag.
