Facial recognition technology has come a long way since Facebook first asked you to tag yourself in your uploaded photos. Refined over the years, it now tags you and your friends automatically, and can identify you in photos even when your face is hidden. Face recognition technology has sat comfortably in pop culture for decades, when detectives on TV scanned databases on the hunt for suspects, the faces blending into each other until PING! It took reality a little longer to catch up to the foresight of Hollywood, and while we haven't reached the invasive face analysis-based advertising showcased in Spielberg's'Minority Report', we may be well on our way. As significant advancements are being made in available processing power and deep learning, face recognition tech has taken off.
