Method and system for aggregation of RFID signal sources and composite to develop a unique signature
First Claim
1. A method of employing radio frequency (RF) identifier (ID) transponder tags (RFID tags) within a data processing system, the method comprising:
- transmitting an interrogation signal or signals toward a person or an object with which a set of one or more RFID tags are physically associated;
obtaining a first set of one or more RFID tag identifiers from an interrogation response signal or signals returned from the set of one or more RFID tags;
performing a mathematical operation on the first set of one or more RFID tag identifiers to generate an RFID signature value;
receiving a request to determine a physical location of the person or the object, wherein the request contains the RFID signature value, and wherein the RFID signature value is employed as an identifier within the data processing system for the person or the object with respect to the request to determine the physical location of the person or the object;
performing an interrogation operation in response to the request to determine the physical location of the person or the object;
computing the physical location of the person or the object based on information within interrogation response signals that are received during the interrogation operation; and
returning a response to report the physical location of the person or the object.

Abstract
A method is presented for employing radio frequency (RF) identifier (ID) transponder tags (RFID tags) to create a unique identifier, termed an RFID signature, for use within a data processing system with respect to a person or an object. An interrogation signal is transmitted toward a person or an object with which a set of one or more RFID tags are physically associated. A first set of RFID tag identifiers are obtained from an interrogation response signal or signals returned from the set of one or more RFID tags. A mathematical operation is performed on the first set of RFID tag identifiers to generate an RFID signature value, which is employed as an identifier for the person or the object within the data processing system with respect to a transaction that is performed by the data processing system on behalf of the person or the object.

6. A method of employing radio frequency (RF) identifier (ID) transponder tags (RFID tags) within a data processing system, the method comprising:
-
transmitting an interrogation signal or signals toward a person or an object with which a set of one or more RFID tags are physically associated; obtaining a first set of one or more RFID tag identifiers from an interrogation response signal or signals returned from the set of one or more RFID tags; filtering the first set of one or more RFID tag identifiers to discard one or more RFID tag identifiers from the first set of one or more RFID tag identifiers prior to performing a mathematical operation to generate an RFID signature value; performing the mathematical operation on the first set of one or more RFID tag identifiers to generate the RFID signature value; and employing the RFID signature value as an identifier for the person or the object within the data processing system with respect to a transaction that is performed by the data processing system on behalf of the person or the object. - View Dependent Claims (7, 8)
