Critical RFID Privacy-Enhancing Technologies

Some of the significant factors associated with RFID technology, that is used to automatically and remotely identify objects, are presented. Security and privacy research community are making significant efforts to develop privacy enhancing technologies (PETs) to prevent unauthorized access to RFID tags. The objective of their efforts is to develop a secure tag-reader communication and to provide consumers an effective management for their privacy in RFID-enabled environment. The on-tag scheme is a privacy scheme in which only RFID readers that can authorize themselves using a particular tag are granted access to the tag. An agent scheme allows an user to delegate privacy management to an agent that mediates tag-reader communication based on general privacy preferences. User scheme involves to design PETs for RFID to enable an user to take control over their RFID tags.
