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.
