The chapter first investigates privacy issues in RFID systems, namely information privacy threats and location privacy threats. RFID systems should be able to resist tag information leakage and tag tracking attacks. Next, the author presents a few formal models in which the notion of privacy in RFID systems is defined. To measure the privacy level of various RFID protocols, a formal privacy definition is needed. Formal models for RFID systems are continually being developed. Here, the chapter describes definitions of RFID systems, adversaries, experiments, and privacy in the most popular models so far: the Avoine model, the Juels-Weis model, and the Vaudenay model.

8.2 Rfid Privacy Issues

This section describes why user privacy is the main concern of users of RFID systems, what kind of privacy issues exist and what privacy requirements in RFID systems are.

Privacy itself is defined in dictionaries as “a state in which one is not observed or disturbed by others”(Oxford dictionary), “someone’s right to keep their personal matters and relationships secret” (Cambridge dictionary), “the quality or state of being apart from company or observation: freedom from unauthorised intrusion” (Merriam-Webster dictionary).

It can be asked: How can the privacy of RFID tag users be threaten? Can users of tags be free from observation or disturbance by unauthorised entities?
