A New Anti-tampering ID Tag that Utilizes Terahertz Waves
A new antitampering tag, based on terahertz waves, has been developed by MIT researchers. It is small, cheap, and secure, similar to traditional RFID tags.
Antitampering Tag Features
Introducing an antitampering tag that’s a mere 4 square millimeters in size. It represents a new advance in the use of terahertz waves for ID, security, and authentication. A machine learning model has been created to accurately detect tampering.
Preventing Tampering
The antitampering tag is based on the glue patterns formed when the tag is attached to an item. The tag contains minuscule slots that allow terahertz waves to interact with the metal particles mixed into the glue. The unique pattern of the metal particles is impossible to duplicate, providing added security.
AI for Authentication
The researchers employed a machine learning model to compare glue patterns and calculate their similarity with great accuracy, overcoming the challenge of taking precise measurements.
Future of Terahertz Waves
The future of terahertz wave technology looks bright, with potential applications in ID, security, and authentication. Technical challenges remain, but the possibilities are enormous.
