Abstract:
Counterfeit articles are distinguished from genuine articles by a combination of a party-specific code and a product authentication code of the article. After authenticating a genuine article, a replacement authentication code is generated based on the original authentication code and party-specific code. Documents and currencies can be authenticated independently of any party-specific code by an addition to or alteration of their authentication code with each authentication event.
