Abstract

A system for use in authentication processes is described comprising a physical unclonable function ("PUF"), a substrate, a plurality of magnetized particles randomly dispersed in the substrate, a PUF reader constructed using multiple discrete magnetometer chips that have magnetic field sensors. The measured magnetic field data may be compared to previously enrolled data to assess authenticity.
