Abstract:
A method of verifying the authenticity of goods, comprising the steps of:creating encrypted combination codes including (a) a respective random code unrelated to the goods and (b) a common, non-personalized to the goods, non-random code that is the same for a number of the combination codes for marking with respect to a number of goods; marking one or more goods with one or more encrypted combination codes such that each of the one or more goods has its own unique random code and the same non-random code; decrypting the encrypted combination codes on the one or more marked goods; and inspecting the decrypted combination codes (i) for presence of the non-random code without having to check a database for commonality thereof, and, if the non-random code is present, (ii) for uniqueness of the random code.
