Abstract
A proxy device is disclosed for use in an RFID system comprising a plurality of RFID devices and at least one reader which communicates with the proxy device and one or more of the RFID devices. The proxy device acquires information characterizing at least a given one of the RFID devices, controls the given RFID device so as to at least partially prevent the given RFID device from being read by the reader, and communicates with the reader in a manner which simulates the given RFID device. This advantageously allows the proxy device to implement privacy policies of arbitrary sophistication on behalf of the given RFID device. The proxy device subsequently releases control of the given RFID device so as to permit the given RFID device to again be read by the reader.
