covert security feature produced by scientists from the University of South Dakota with nanoparticle ink that can only be seen under 980 nanometer wavelength light.
The US National Science Foundation (NSF) has awarded around 4Bn$ of grants to the University of South Dakota for the launch of two research projects related to illicit trade and counterfeiting.
The first one named “Cyber-Physical-Social System for Understanding and Thwarting the Illicit Economy” target the identification of counterfeit items while the second one aims at studying how illegal networks operate. Both projects specifically focus on the development of anti-counterfeit technologies that can help identify authentic goods such as nanoparticle-based inks and security printing.
