  Facial recognition is changing the way we live in and interact with our
society. Here we discuss the two sides of facial recognition, summarizing
potential risks and current concerns. We introduce current policies and
regulations in different countries. Very importantly, we point out that the
risks and concerns are not only from facial recognition, but also realistically
very similar to other biometric recognition technology, including but not
limited to gait recognition, iris recognition, fingerprint recognition, voice
recognition, etc. To create a responsible future, we discuss possible
technological moves and efforts that should be made to keep facial recognition
(and biometric recognition in general) developing for social good.
