Collision Avoidance on National and Global Scales: Understanding and Using Big Biometric Entropy
preprintposted on 2021-02-24, 00:43 authored by John DaugmanJohn Daugman
Large-scale testing involving more than a trillion comparisons between the iris patterns of different persons has confirmed that the entropy of IrisCodes is large enough to deliver collision avoidance (absence of False Matches) in population sizes of national, continental, and even planetary scale. This short paper explains how the entropy of this biometric achieves it.
