Researchers from the National University of Singapore (NUS) have developed an anticounterfeiting technology – called DeepKey – based on 2D-material tags and artificial intelligence (AI) authentication software.
A key element of their approach is the use of durable identification tags that are not easily damaged by environmental conditions such as extreme temperatures, chemical spills, UV exposure, and moisture, according to the team, led by Chen Po-Yen and Wang Xiaonan from NUS’ Department of Chemical and Biomolecular Engineering.
The 2D tags include physically unclonable function (PUF) patterns that are randomly generated by “crumpling” the thin film material used to make them.
The PUF pattern is then attached to a QR code to link the authentication element to the cloud and allow traceability, with the PUF lined to the code using a database – a process that can take “less than 3.5 minutes,” according to the researchers.
