« An invisible quick response (QR) code has been created by researchers in an attempt to increase security on printed documents and reduce the possibility of counterfeiting, a problem which costs governments and private industries billions of pounds each year. »

« According to the researchers, the QR code will add an increased level of security over existing counterfeiting methods as the complexity of the production process makes it very difficult to replicate. »

They really don't get it, do they?

I mean, it seems that the only solution they can find against counterfeiting consists in making the fabrication process more and more difficult, and hope that counterfeiters will not have enough technical skills.

Yet the truth seems quite simple to me:   if a government can do it, or can pay technicians to do it, then anyone, with enough time and money can do it as well, with just a bit of reverse engineering and motivation.
