Abstract:
This paper presents the most comprehensive analysis of iris recognition reliability in the occurrence of various
biological processes happening naturally and pathologically in the human body, including aging, illnesses, and
post-mortem changes to date. Insightful conclusions are offered in relation to all three of these aspects. Extensive
regression analysis of the template aging phenomenon shows that differences in pupil dilation, combined
with certain quality factors of the sample image and the progression of time itself can significantly degrade
recognition accuracy. Impactful effects can also be observed when iris recognition is employed with eyes
affected by certain eye pathologies or (even more) with eyes of the deceased subjects. Notably, appropriate
databases are delivered to the biometric community to stimulate further research in these utterly important
areas of iris biometrics studies. Finally, some open questions are stated to inspire further discussions and research
on t
hese important topics. To Authors’ best knowledge, this is the only scientific study of iris recognition
reliability of such a broad scope and novelty.
