Biometric Aging: Effects of Aging on Iris Recognition
Abstract
The fundamental question being asked is, does iris recognition performance remains constant and persist well over time? Or conversely, is the iris structure susceptible to irreversible changes that cause greater dissimilarity as time intervals between recognition events increase? Medical literature reports that the pupil size decreases slightly as people age [1]. However, the iris is naturally protected within the body, with protective coverings (eyelids and cornea) that prevent the physical surface wear and tear, and loss of moisture experienced by fingerprints and the skin and soft tissue on the face. There are certainly disease and vision related ailments that occur with age; the eye can suffer presbyopia, cataracts and other diseases. But the fundamental assumption for iris recognition is that the structure and patterns in the elastic connective tissue of the iris remain stable and permanent throughout life.
