Biometric screening using fingerprint or retina scans are not new. Since the advancements in high-resolution cameras and development of 3D facial recognition algorithms in the past few years, facial recognition as a means of biometrics has become pretty popular. My first encounter with this technology was in 2012–13 timeframe when Google first released its Face Unlock, a feature in one of their Android Operating Systems that could unlock the phone by recognizing the owner’s face.

Thus, facial recognition is not new. What is new is the access to some of the most sophisticated facial recognition algorithms through open source libraries and AWS AI services (a.k.a. Rekognition) to developers. We are going to talk about some of these libraries in this blog.
