Biometric Security and Surveillance: More than the Subject of Science Fiction

If you’ve ever used the fingerprint scanning feature to access your smartphone, you’re familiar with biometric technology. Biometrics—the use of biological (physical and behavioral) characteristics such as fingerprint, face, and iris scanning to perform identity verification—is a maturing field, and applications of the technology are expected to grow in the years ahead. In fact, it’s predicted that biometrics will be used to authenticate 25% of all electronic transactions worldwide by 2020, according to International Data Corporation (IDC).
