Location Aware Selective Unlocking for Enhancing RFID Security

In this paper, a new approach for providing security as well as privacy is proposed. The un-authorized reading and relay attacks on RFID system is avoid by using location sensing mechanism. For example, location sensing mechanism used for location specific application such as on the door of ATM cash transfer van for providing security because the location of the van is fixed. So after reaching the pre-specified location the RFID card is active and then it accepts the fingerprints of the registered person, in this way a stronger cross layer security is provided. The location awareness is used by both tags and back-end servers for defending against unauthorized reading and relay attacks onRFID systems.
