Privacy Protection based on User-defined Preferences in RFID System

Radio frequency identification, known as RFID, is fast becoming one of the most controversial technologies at present. Because the radio waves emitted from RFID reader are invisible, it's really hard to detect who reads a tag attached to or incorporated into products owned by a person. A significant concern to privacy threats in RFID system arises from this reason. Privacy threats are not just problem. Security is also another critical consideration. Many solutions have been proposed to address these fundamental problems and facilitate the benefits of RFID system. However, many of them are hard to implement in practice, even though their approaches are theoretically plausible in the literature. Keeping them in mind, we will design "preferences" oriented communication protocol rather than contrive new algorithm or hardware modules to prevent ill-intentioned uses of RFID technology. The concept "preferences" is originated on P3P
