Linoprint, an innovation project run by German press giant Heidelberg, is developing an anti-piracy system for packaging which works using a combination of two security technologies and an optical verification system.

Linoprotect uses ultra-thin copper or metal threads that are combined to generate a random pattern which is applied to the packaging on a label. This pattern is read by the Linoprotect reading module.

A cryptographic key that is unique to each customer converts the pattern into an equally unique data matrix code. This code is printed onto the packaging next to the label with the pattern of copper threads using a digital Linoprint Drop on Demand inkjet system.

Brand manufacturers, customs officers and customers can check the authenticity of a product labelled with Linoprotect using just a mobile phone camera or a scanner and special software that is freely available.

The software compares the two Linoprotect security features on the product or packaging and immediately identifies whether or not the content of the data matrix code matches the pattern in the adjacent field.

Linoprotect can also be integrated into new or existing packaging lines. The point at which the system is applied is determined by the production environment and by the product being labelled.

The system also enables brand goods manufacturers to provide customers and dealers with various items of additional information, such as the sell by date or dosage information.
