Method and system for deterring product counterfeiting, diversion and piracy
View Patent ↗A client system receives a request for a set of unique security codes and also receives product data associated with a product on which the security codes are to be printed. The client sends at least some of the product data to a host system and receives a batch identifier from the host. The host stores received product data with the batch identifier. The client generates the set of security codes and then provides the codes to be printed on the product. After the products enter the stream of commerce, the host can receive an authentication request including a security code, and in response the host will verify that the security code is valid and return to the requestor the authentication result and at least part of the product data associated with the batch identifier.
1. A method comprising:
communicating a request to a host, the request including product data, the product data being associated with multiple units of a product on which unique security codes are to be marked;
receiving, by a client and from the host, a batch identifier and a batch key;
generating, using a processor of the client, the unique security codes from the batch identifier and batch key; and
marking a different unique security code of the unique security codes on each of the multiple units of the product.
2. The method of claim 1 wherein marking the unique security codes on the multiple units of the product includes, for each unit of the product, attaching an RFID tag to the unit and writing to the RFID tag the different unique security code.
3. The method of claim 1 wherein marking the unique security codes on the multiple units of the product includes, for each unit of the product, printing the different unique security code on the unit.
4. The method of claim 1 wherein the request to the host is communicated from the client.
5. The method of claim 1 wherein generating each unique security code comprises the client generating a serial number.
6. The method of claim 5 wherein generating each unique security code further comprises the client producing a verification value by using the batch key and either of the serial number or the batch identifier.
7. The method of claim 1 wherein the product data comprises an intended destination of the product.
8. The method of claim 7 further comprising determining an instance of diversion by finding that a geographical location of a unit of the product is different than the intended destination.
9. The method of claim 8 wherein determining the instance of diversion is performed by a consumer.
10. A method comprising:
receiving a request from a client, the request including product data, the product data being associated with multiple units of a product on which unique security codes are to be marked;
generating, with a processor, a batch identifier and a batch key in response to receiving the request;
storing the product data in association with the batch identifier;
sending the batch identifier and the batch key to the client;
receiving, from a source other than the client, an authentication request including a security code; and
authenticating the security code.
11. The method of claim 10 wherein authenticating the security code includes determining the batch identifier.
12. The method of claim 11 further comprising using the batch identifier to retrieve at least a part of the product data.
13. The method of claim 11 further comprising sending the at least part of the product data to the source of the authentication request.
