Abstract
A system, device, and method for binding metadata, such as information derived from the output of a biometric sensor, to hardware intrinsic properties by obtaining authentication-related metadata and combining it with information pertaining to a root of trust, such as a physical unclonable function. The metadata may be derived from a sensor such as a biometric sensor, the root of trust may be a physical unclonable function, the combination of the metadata and root of trust information may employ a hash function, and output from such a hash process may be used as an input to the root of trust. The combined information can be used in interactive or non-interactive authentication.
