Heidelberg Offers Protection Against Counterfeiting
Ultimate protection against counterfeiting
1-TAG is based on a combination of physical random processes and cryptographic signatures. The term cryptographic signature refers to processes that can be used to document the authenticity of data and enable this data to be checked by everyone. First, a pattern randomly generated from copper threads is applied to a label. This pattern is read off using a camera, and a cryptographic key that is unique to each manufacturer converts it into an equally unique code. This cryptographic signature ensures that the random pattern, code, and product information are linked up in such a way that they offer reliable protection against manipulation. The code is printed on the label next to the pattern of copper threads using a digital drop-on-demand inkjet system from Linoprint.
