“Iris Scan Please,” the bank’s computer voice tells you. You step up and the computer reads your eye, comparing it to the stored file it has of your iris. The images had better match - otherwise, you won’t be able to get your money.
Many science fiction films have used technologies such as iris, fingerprint, or voice scans as part of the story. Well, folks, believe it or not, these seemingly advanced technologies may soon be prevalent at work, the bank, the airport, and your local prison. The iris scan, fingerprint scan, and voice scan are all examples of biometrics, an exploding area of automatic personal identification technology. Basically, biometrics uses various means of identity verification based on an individual’s unique physiological and/or behavioral characteristics. These tests generally compare the captured image to a stored image, checking for matches in the particular pattern or characteristic being tested.
