Unclonable Product Tags

Unclonable Product Tags
Feb-09-19
An innovative unclonable tag relies on a random spraying of microparticles to help fight counterfeiters.

A team from the University of Copenhagen created the product tags using physical unclonable functions (PUFs), which are impossible to replicate—even by the manufacturer. The tags are made up of standard laser-printed QR codes that have been sprayed with PUF inks containing microparticles. The tiny dots of ink are visible on the black background, forming random patterns that can be logged in a registry and then identified using a smartphone to determine the object’s validity.
