- Abstract: Iris is an established modality in biometric recognition applications
including consumer electronics, e-commerce, border security, forensics, and
de-duplication of identity at a national scale. In light of the expanding usage
of biometric recognition, identity clash (when templates from two different
people match) is an imperative factor of consideration for a system's
deployment. This study explores system capacity estimation by empirically
estimating the constrained capacity of an end-to-end iris recognition system
(NIR systems with Daugman-based feature extraction) operating at an acceptable
error rate i.e. the number of subjects a system can resolve before encountering
an error. We study the impact of six system parameters on an iris recognition
system's constrained capacity -- number of enrolled identities, image quality,
template dimension, random feature elimination, filter resolution, and system
operating point. In our assessment, we analyzed 13.2 million comparisons from
5158 unique identities for each of 24 different system configurations. This
work provides a framework to better understand iris recognition system capacity
as a function of biometric system configurations beyond the operating point,
for large-scale applications.
