A study of mobile proxy for privacy enhancement

Radio frequency identification (RFID) is a promising technology for identifying physical objects in an automated manner, but raises privacy infringement problems significantly in the real world. The low-cost RFID tags are much more vulnerable, meaning traceable, than active tags due to their restricted (poor) capabilities. In this paper, we present a practical method for enhancing the privacy of consumers, who may hold low-cost tags in everyday life, through a mobile phone. We set the mobile phone as a mobile proxy, which registers and renames RFID tags, monitors radio communications, and simulates the low-cost tags for privacy enhancement, along with providing a user setting mechanism for privacy levels.
