Radio frequency identification system with privacy policy implementation based on device classification
First Claim
1. A method for use in an RFID system comprising a plurality of RFID devices and at least one reader which communicates with one or more of the devices, the method comprising the steps of:
- receiving identifiers transmitted by the RFID devices;
determining a classification of at least one of the received identifiers; and
implementing a privacy policy for data associated with one or more of the received identifiers based at least in part on the determined classification.

Abstract
Methods and apparatus are disclosed for use in an RFID system comprising a plurality of RFID devices and at least one reader which communicates with one or more of the devices. In accordance with an aspect of the invention, identifiers transmitted by the RFID devices are received by the reader. The system determines a classification of at least one of the received identifiers, and implements a privacy policy for data associated with one or more of the received identifiers based at least in part on the determined classification. For example, the given RFID device may be configurable into at least a first state indicative of a first classification, such as a private classification, and a second state indicative of a second classification, such as a public classification. The reader may alter a type of query that it issues based at least in part on the determined classification. Alternatively or additionally, response by the given RFID device to a query received from the reader may be conditioned on the state of the RFID device. The reader may be configured, dynamically or otherwise, so as to issue queries causing such selective responses by the RFID devices.

34. An apparatus for use in an RFID system comprising a plurality of RFID devices and at least one reader which communicates with one or more of the devices, the apparatus comprising:
-
an RFID device configurable into at least a first state indicative of a first classification and a second state indicative of a second classification;
wherein the system upon receipt of identifiers transmitted by the RFID devices is operative to determine a classification of at least one of the received identifiers, and to implement a privacy policy for data associated with one or more of the received identifiers based at least in part on the determined classification.

35. An apparatus for use in an RFID system comprising a plurality of RFID devices and at least one reader which communicates with one or more of the devices, the apparatus comprising:
-
an RFID device configurable into at least a first state indicative of a first classification and a second state indicative of a second classification;
the RFID device being further configured to receive from the reader a query for which response by the RFID device is conditioned on the state of the RFID device;
the system thereby implementing a privacy policy for data associated with one or more RFID device identifiers received by the reader, based at least in part on one or more classifications determined for the one or more received identifiers.

-
36. An RFID system comprising:
-
at least one RFID device; and
at least one reader which communicates with the RFID device;
the reader receiving an identifier transmitted by the RFID device;
the system being operative to determine a classification of the received identifier, and to implement a privacy policy for data associated with the received identifier based at least in part on the determined classification.

37. A method for use in an RFID system comprising a plurality of RFID devices and at least one reader which communicates with one or more of the devices, the method comprising the step of:
-
configuring a given one of the RFID devices in one of at least a first state indicative of a first classification and a second state indicative of a second classification;
wherein response by the given RFID device to a query received from the reader is conditioned on the state of the RFID device;
the system thereby implementing a privacy policy for data associated with one or more RFID device identifiers received by the reader, based at least in part on one or more classifications determined for the one or more received identifiers.
