Live facial recognition: The poster child of biometric surveillance
Live facial recognition has become the defining example of biometric surveillance technology, drawing scrutiny for its real-time identification of people in public spaces. The technology is increasingly deployed by law enforcement and private operators, making it a focal point in debates over civil liberties and data use.
Why this matters: Most surveillance happens after the fact. Live facial recognition is different. It identifies you in the moment, as you move through a street, a stadium, a protest. You have not done anything. You have not consented to anything. Your face is just being read. That is a qualitative shift in what public space means. The hard part is that the systems are already running in many places before the rules about them are settled. By the time the law catches up, the infrastructure will already be built.
