Experiment shows that a person equipped with just a few cameras and facial recognition technology can learn people’s daily habits: when they arrive at the office each day, who they get coffee with, whether they left work early. When we identified Dr. Madonna, he was on his way to lunch with a job candidate — an example of how the midday outings of even law-abiding citizens can sometimes be sensitive information.
The police and governments may also have access to a vast network of cameras. Combine that with a comprehensive database of faces — like a driver’s license database — and it’s possible to track citizens throughout an entire region in real time.
