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.
