Technology is taking the field of biometrics to new levels of accuracy and efficiency. But is the price of such security, achieved by turning over unique bodily information to governments and private companies, too high? And is biometric data really as foolproof as its proponents say? This program travels the globe to showcase examples of high-tech biometrics in action, including electronic recognition of iris patterns, fingerprints, faces, hand vein patterns, handwriting, and gait. In addition, Alex Turk, chairman of France's national commission on data protection and civil liberties, voices his concern over people's passive acceptance of biometric technologies, and a hacker demonstrates just how easy it is to fake out a fingerprint scanner.
