Duplication detection for non-cryptographic rfid tags using encrypted traceability information

A computer program product for detecting duplicate radio frequency identification (RFID) tags, the computer program product being tangibly embodied on a computer-readable medium and including executable code that, when executed, is configured to cause at least one data processing apparatus to execute a duplication detection module, the duplication detection module configured to:

• determine if data on a RFID tag received by a receiving party is encoded;
• if the data on the RFID tag is not encoded, determine that the RFID tag is a duplicate RFID tag and that an item associated with the duplicate RFID tag is counterfeit;
• if the data on the RFID tag is encoded, cause a decoder to decode the data on the RFID tag using a private key of the receiving party as a decoding parameter;
• check for an item identifier and a sender identifier as a part of the encoded data;
• determine whether the item identifier has previously been read to determine if the RFID tag was duplicated during transport;
• and
• compare the sender identifier with an expected sender identifier to determine if the RFID tag was duplicated during transport.

A radio frequency identification (RFID) tag, comprising:

• a receiver module that is arranged and configured to receive an encrypted item identifier and an encrypted sender identifier from a sending party, the encrypted item identifier and the encrypted sender identifier being encrypted using a public key of a receiving party;
• and
• a storage module that is arranged and configured to store the encrypted item identifier and the encrypted sender identifier,
• wherein the encrypted item identifier and the encrypted sender identifier are decodable only by the receiving party using a private key of the receiving party to authenticate the RFID tag.

A system comprising:

• a decoder that is arranged and configured to read data stored on a radio frequency identification (RFID) tag;
• and
• a duplication detection module that is operably coupled to the decoder and that is arranged and configured to:
• determine if data on a RFID tag received by a receiving party is encoded;
• if the data on the RFID tag is not encoded, determine that the RFID tag is a duplicate RFID tag and that an item associated with the duplicate RFID tag is counterfeit;
• if the data on the RFID tag is encoded, cause the decoder to decode the data on the RFID tag using a private key of the receiving party as a decoding parameter;
• check for an item identifier and a sender identifier as a part of the encoded data;
• determine whether the item identifier has previously been read to determine if the RFID tag was duplicated during transport;
• and
• compare the sender identifier with an expected sender identifier to determine if the RFID tag was duplicated during transport.
