MIT researchers have created a microscopic, low-cost cryptographic ID tag, designed to protect products from counterfeiting by providing improved security compared to traditional radio frequency tags (RFIDs). The technology, developed using terahertz waves, can offer a highly secure, low-cost, and easy-to-implement solution in preventing tampering and ensuring product authenticity. RFID tags typically use radio waves to…

Researchers at Massachusetts Institute of Technology (MIT) have developed a small, low-cost cryptographic ID tag that improves the security of product authentication. The new design mitigates a common security issue where counterfeiters could transfer an ID tag from an authentic product to a fake one, deceiving authentication systems. This ID tag uses terahertz waves and…

Researchers from MIT have developed a cryptographic ID tag that's considerably smaller, more secure, and cost-effective than traditional radio frequency tags (RFIDs) regularly used in product authenticity verification. These ID tags use terahertz waves, which are smaller and have higher frequencies than radio waves, thus being more compact and secure. An issue with traditional RFIDs is…

A few years ago, MIT researchers created an innovative cryptographic ID tag several times smaller and much cheaper than traditional RFIDs (radio frequency tags) commonly used to authenticate products. Despite the significant improvements in size, cost, and security this new ID tag brought, it shared a major security vulnerability with RFIDs, where a counterfeiter could…

Researchers from the Massachusetts Institute of Technology (MIT) have developed an antitampering ID tag that uses terahertz waves to make products almost impossible to counterfeit. The tag uses microscopic metal particles mixed with the glue that attaches the tag to a product. The terahertz waves can detect the unique pattern created by the metal particles,…

MIT researchers have developed an antitampering cryptographic ID tag that offers improved security, lower cost and a much smaller size than traditional radio frequency tags. The previous generation of terahertz tags, like radio frequency identifiers (RFIDs), were vulnerable to tampering, as fraudsters could move the tags from genuine to counterfeit goods without the authentication system…
