An Overview of Approaches to Privacy Protection in RFID

Radio Frequency Identification (RFID) is a common term for technologies using micro chips that are able to communicate over short-range radio and that can be used for identifying physical objects. RFID technology already has several application areas, and more are being envisioned all the time. While it has the potential of becoming a really ubiquitous part of the information society over time, there are many security and privacy concerns related to RFID that need to be solved. These issues have been addressed quite extensively by researchers in this field, and as a result, several protection mechanisms have been developed for different types and uses of this technology. This paper examines some of these proposed technical approaches to privacy protection in order to find out their suitability in terms of security versus utility in their proposed domains of application.
