Detecting Faces, Saving Lives

Your phone scans your face to unlock its screen. A social media app offers suggestions of friends to tag in photos. Airline check-in systems verify who you are as you stare into a camera. These are just a few examples of how facial recognition technology (FRT) is now ubiquitous in everyday lives. The industries of law enforcement, Internet search engines, marketing, and security have long harnessed FRT, but the technology is becoming increasingly explored in the health care setting, where its potential benefit-and risks-are much greater.
