"‘Biometrics is at the forefront in our agenda for homeland security,’ declared Asa Hutchinson, the Department of Homeland Security's undersecretary for border and transportation security, at the 2004 Biometric Consortium Conference” [11]. Flashy retinal scanning and voice activated computers were once considered technologies for science fiction movies and novels. Nowadays, such technologies are widely used across the nation—in airports, trucking companies, and casinos—by both private and government organizations. These technologies are termed as biometrics. They use a certain physiological characteristic that is unique to a person as a means of identification. As Hutchinson said, it is an important agenda item for homeland security. By using paradigm case analyses, the morality of using biometrics will be discussed.
