Pharmaceutical product packaging
First Claim
1. A method of verifying the authenticity of a product, the method comprising:
- 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.

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 a pharmaceutical product;
providing on the data storage device an identity code for the data storage device, a random first identifier 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;
receiving a communication from a third party seeking verification information;
checking that a first identifier received from the third party is a valid first identifier; and
providing the second identifier to the third party, thereby to enable the third party to verify the digital signature using the second identifier. - View Dependent Claims (13, 14, 15, 16)
