Abstract
Methods for producing and validating RFID transponders (e.g., ISO 11784/11785 compliant transponders) with identification number authentication capabilities. A signature indicator and a partial-signature trailer are introduced to the ISO telegram. An encrypted signature or partial signature is introduced to the internal memory of ISO compliant transponders. The encrypted signature can prevent fraudulent duplications of ISO 11784/11785 transponders by allowing users to securely validate the transponders' authenticity.
Claims20
A radio frequency identification (RFID) transponder, comprising:
- a radio frequency (RF) transceiver;
- and
- memory in communication with the RF transceiver, the memory storing data retrievable by a scanner via the RF transceiver and comprising:
- (i) read-only memory comprising:
- a code unique to the RFID transponder, wherein the RFID transponder is programmed to transmit the code upon receiving a memory-read signal by the RFID transponder;
- and
- a first sub-signature that is a first portion of a signature, wherein the first sub-signature is read-only;
- (ii) field-programmable memory comprising an RFID telegram, the RFID telegram comprising an identification code, a signature indicator, and a second sub-signature that is a second portion of the signature,
- wherein the RFID transponder is programmed to:
- transmit the first sub-signature upon receipt of the memory-read signal by the RFID transponder, and
- transmit the second sub-signature upon an activation of the RFID transponder.
A scanner for validating a radio frequency identification (RFID) transponder, the scanner comprising:
- memory;
- one or more processors in communication with the memory, wherein the one or more processors are configured to:
- receive an RFID telegram stored in field-programmable memory of the RFID transponder by an activation of the RFID transponder with a radio frequency (RF) signal from the scanner;
- based on receiving the RFID telegram, transmit a memory-read signal to the RFID transponder, wherein the transmission of the memory-read signal causes the RFID transponder to transmit read-only data stored in read-only memory of the RFID transponder to the scanner;
- and
- receive the read-only data from the RFID transponder,
- wherein the read-only memory of the RFID transponder comprises a first sub-signature that is a first portion of a signature, and the read-only data comprises the first sub-signature, and
- wherein the RFID telegram comprises an identification code, a signature indicator, and a second sub-signature that is a second portion of the signature.
A method for validating a radio frequency identification (RFID) transponder, the method comprising:
- receiving an RFID telegram stored in field-programmable memory of the RFID transponder by an activation of the RFID transponder with a radio frequency (RF) signal from the scanner;
- based on receiving the RFID telegram, transmitting a memory-read signal to the RFID transponder, wherein the transmission of the memory-read signal causes the RFID transponder to transmit read-only data stored in read-only memory of the RFID transponder to the scanner;
- and
- receiving the read-only data from the RFID transponder,
- wherein the read-only memory of the RFID transponder comprises a first sub-signature that is a first portion of a signature, and the read-only data comprises the first sub-signature, and
- wherein the RFID telegram comprises an identification code, a signature indicator, and a second sub-signature that is a second portion of the signature.
