“The most promising is a technique developed by InfraTrac” (3dprint.com) Cyber-physical security for 3D printing, packaging, drugs, electronics: InfraTrac’s chemical fingerprints protect against counterfeiting, with a covert internal taggant mix that can be authenticated instantly, anywhere. Additive manufacturing is moving from prototyping into manufacturing, starting with defense and aerospace spare parts and medical devices. The rise of 3D scanners makes it possible for anybody to make a copy, authorized or not, and there have not been ways to validate the object itself. InfraTrac’s patented technology places layers inside the object, managed with secure printer software, to protect both brands and national security. Validation uses a special light, an off-the-shelf, pocket-sized spectrometer, that provides a simple yes-no answer: genuine or fake. Beyond 3D: Wrap: Coded plastic, paperboard, or coated metal lets you protect shrinkwrap, neckbands, blister packs, bottle sleeves, ingredient packaging, or snack packs, verified in an instant, anywhere in the supply chain. Drugs: Patented in-dose fingerprinting offers the promise of tracking substances, not just packaging. Currently optimized for powders and pills, it is also capable of tracking liquids. The easiest way to take advantage of in-dose fingerprinting is to change the formulation of inactive ingredients. Tiny changes are detected spectroscopically … so tiny that no new FDA approval is needed, since the alterations fall within the SUPAC level 1 guidelines, for Scale-Up and Post-Approval Changes. Use coded taggants or in-dose fingerprinting to track thousands of batches, and detect both black market and gray market interlopers.
