Biometric technology, used to identify individuals based on their unique, unchangeable attributes such as fingerprints, face prints, and retinas, has grown in use over the last five to ten years as biometrics are incorporated into popular devices and different areas of our lives.1 Today, many people around the world use their face or their thumbprint as a password to unlock their smartphone or complete transactions, and many others use the technology to clock in at work, to see who rang their doorbell at home, or to access secure facilities.
