No more counterfeited goods (NoFakes) – FNR/Pathfinder, 2020

NOFAKEs Authentication Technology focuses on the development of algorithms to capture, extract, and process the encoded information from Cholesteric Spherical Reflectors (CSRs). CSRs produce unpredictable and unique optical reflection patterns when coated on transparent and flat surfaces.

Technologies that offer unclonable properties are envisioned for a wide range of applications, including verifying the authenticity of objects, identification protocols, access control, electronic document management, etc. CSR tags can be potentially used for anti-counterfeit purposes because of their fingerprint-like attributes. The extraction of robust information, as well as authentication protocols, are key components to defining whether an object is authentic or not.

NOFAKES project has a close collaboration with the Experimental Soft Matter Physics 
(ESMP) group from the Physics & Materials Science Research Unit at the University of Luxembourg. We have also established industrial collaborations with companies that are interested in implementing anti-counterfeiting technologies, and companies that already use some anti-counterfeiting technologies, but are interested in testing other novel solutions.

Partner companies:

  • United Caps – packaging industry, Luxemburg-based company I.G.
  • Bressan – pharmaceutical packaging sector, based in Italy.
