Eye and Iris Sensors

Abstract

AbstractWe explain how iris recognition can provide an unalterable, reliable biometric solution without encumbering the subject. We describe the structure of the human eye and the benefits of removing ambiguity to prevent human identification systems from rejecting valid subjects or validating imposters. Such failures in identification can be disastrous, especially in counterterrorism and law enforcement applications. We describe the fundamental processes required for an iris recognition system and describe current techniques used for acquiring and encoding iris images. We discuss the difficulties of encoding poorly presented or occluded iris images along with the unmet needs, on‐going research in iris segmentation, and the need to develop reliable, noninvasive identification systems. We then address the potential for applying iris recognition technology to persons in motion and the challenges of this technology.Accurate, reliable identification of humans is a goal as ancient as humanity. As technology and services have developed, humans regularly engage in transactions in which rapid and reliable personal identification is required. Examples include passport control, computer login control, automatic teller machines and other financial transaction authorizations, premises access control, and security systems for meeting the critical needs of homeland security. Speedy, reliable, automated identification procedures are especially necessary for law and counterterrorism enforcement.
