A cryptographic tag developed at MIT uses terahertz waves to authenticate items by recognizing the unique pattern of microscopic metal particles that are mixed into the glue that sticks the tag to the item’s surface.
After passing through the tag and hitting the surface of an object, the terahertz waves are reflected or backscattered and reach a receiver for authentication.Credit: Ruonan Han, Eunseok Lee, et al. Several years ago, MIT researchers invented a cryptographic ID tag that is several times smaller and significantly cheaper than traditional radio frequency tags […]
