Abstract

A method of verifying the authenticity of a product includes reading data from a data storage device which forms part of the packaging of the product, determining from the data an identity code for the data storage device, a random first identifier allocated to the data storage device by the product manufacturer and a digital signature of a parameter which is based on at least a second identifier not derivable from the data, communicating with the product manufacturer or an entity associated therewith using the random first identifier as a reference, receiving from the product manufacturer or the entity associated therewith the second identifier, and verifying the digital signature using the second identifier.

Claims

1. A method of verifying the authenticity of a product, the method comprising:

reading data stored on a data storage device which forms part of the packaging of the product, wherein said data comprises a random first identifier uniquely allocated to the data storage device and a digital signature of a parameter which is based on at least a second identifier not derivable from the data;

communicating with the product manufacturer or an entity associated therewith using the random first identifier as a reference;

receiving from the product manufacturer or the entity associated therewith the second identifier; and

verifying the digital signature using the second identifier received from the product manufacturer or the entity associated therewith.

2. A method as claimed in claim 1, wherein verifying the digital signature comprises calculating the parameter, and verifying that the calculated parameter corresponds to the digitally signed parameter thereby to verify the digital signature.

3. A method as claimed in claim 1, wherein the data read from the data storage device further comprises data concerning the product.

4. A method as claimed in claim 3, wherein the data concerning the product comprises an image file showing the appearance of the product and/or the packaging.

5. A method as claimed in claim 3, wherein the data concerning the product comprises product expiry information and/or dosage information and/or drug provenance information.

6. A method as claimed in claim 3, wherein the parameter comprises a function of the data concerning the product, the first random identifier, an identity code for the data storage device, and the second identifier.

7. A method as claimed in claim 6, wherein the parameter is a function also of a packaging identifier included in the data read from the data storage device.

8. A method as claimed in claim 7, wherein the parameter is a function also of a packaging seal identifier included in the data read from the data storage device.

9. A method as claimed in claim 1, wherein the method further comprises verifying the packaging is intact.

10. A method as claimed in claim 1, wherein reading data comprises using a short range reader, with a range of less than 5 mm.

11. A method as claimed in claim 1, wherein the product is a pharmaceutical product.

21. A method as claimed in claim 1, wherein verifying the digital signature comprises using a public key of the manufacturer or the entity associated therewith.

12. A method of providing data for verification of the authenticity of a pharmaceutical product, the method comprising:

providing a data storage device as part of the packaging of the pharmaceutical product;

storing data on the data storage device, wherein said data comprises an identity code for the data storage device, a random first identifier uniquely allocated to the data storage device and a digital signature of a parameter based on at least a second identifier not derivable from the data; and

upon receipt of the first identifier from a third party and upon verification that the received first identifier is valid, providing the second identifier to the third party, thereby to enable the third party to verify the digital signature using the second identifier.

13. A method as claimed in claim 12, further comprising providing a public key to the third party to enable the third party to verify the digital signature.

14. A method as claimed in claim 12, wherein the data stored on the data storage device further comprises data concerning the pharmaceutical product.

15. A method as claimed in claim 14, wherein the data stored on the data storage device further comprises an image file showing the appearance of the product and/or the packaging.

16. A method as claimed in claim 14, wherein the parameter is a function of the data concerning the pharmaceutical product, the first random identifier, the identity code and the second identifier.

22. A method as claimed in claim 12, further comprising:

determining whether or not to release the second identifier to the third party based on history information that indicates a possible previous release of the second identifier.

23. A method as claimed in claim 22, wherein, if the history information indicates that the second identifier has been released before,

refusing to release the second identifier to the third party;

or

releasing the second identifier to the third party with a warning.

24. A method as claimed in claim 23, further comprising:

providing the history information to the third party.

17. A pharmaceutical product packaging comprising a data storage device storing read only data, the data comprising:

an identity code for the data storage device;

a random first identifier allocated to the data storage device by the pharmaceutical product manufacturer or an entity associated therewith; and

a digital signature of a parameter, which parameter is based on at least a second identifier not derivable from the data.

18. A pharmaceutical product packaging as claimed in claim 17, wherein the data further comprises data concerning the pharmaceutical product.

19. A pharmaceutical product packaging as claimed in claim 18, wherein the data further comprises an image file showing the appearance of the product and/or the packaging.

20. A pharmaceutical product, comprising:

a drug; and

a packaging as claimed in claim 17.
