ePrint Report: FiveEyes: Cryptographic Biometric Authentication from the Iris

Luke Demarest, Sohaib Ahmad, Sixia Chen, Benjamin Fuller, Alexander Russell

Despite decades of effort, a stubborn chasm exists between the theory and practice of device-level biometric authentication. Deployed authentication algorithms rely on data that leaks private information about the biometric; thus systems rely on externalized security measures such as trusted execution environments. In particular, the authentication algorithms themselves provide no cryptographic security guarantees.


This is particularly frustrating given the long line …
