How Facial Recognition Might Stop the Next Brussels

The departments of Defense and Homeland Security have invested in technology to prevent attacks like the one in Brussels, including facial recognition technology that can spot and flag a suspected terrorist in a car heading toward an airport or crowded subway. But bringing that technology out of the lab and getting it to airports and street corners is a lot harder than just snapping a photo.

...In order to thwart an attack, a facial-recognition-based system must have access to a database that already contains the would-be perpetrator’s face, sensors that can obtain usable snapshots of people approaching the protected area, and a way to alert guards or otherwise cut off access to the target. Getting all three of those at once is the challenge of securing a place like an airport’s departure area or a metro station.
