O-Pur

O-Pur is a product protection concept based on identification and authentication. It is built on the simple fact, that each printed matrix code has its individual non-replicable characteristics. Its unique fingerprint, resulting from the physical interaction between medium and substrate during the printing process, can be used to identify whether the product is original or not. If the code is applied on the secondary package, its contents are used to identify the product.
This concept shows, that conventional offset printing can provide anti-counterfeit marking for mass production. The main features of the presented product authenticating system are: adaptable security level, easy integration into the production chain, easy offline and online verification with and without access to a database and the interoperability with existing track-and-trace solutions.
