'Biometrics' Used to Identify Terrorists

Computer scientists and engineers are working with intelligence agencies on an international collaborative database that will use biometrics or unique individual facial, voice and physical "signatures", to identify and trace terrorists and persons of interest.

The combination of a facial expression, a spoken word, or a fingerprint could be enough to stop a terrorist attack.

While tenable results for accuracy, speed and timing are five and 10 years out, the goal is to combine biometrics with artificial intelligence to prevent terrorist attacks—an ambitious, expensive, but worthwhile endeavor.
