Facial Recognition on London Underground
Facial recognition technology is being deployed on the London Underground, according to reporting in Professional Security Magazine. The system would scan the faces of passengers traveling on one of the world's busiest transit networks.
Why this matters: Millions of people ride the Tube every day without thinking twice about it. Adding facial recognition to that routine means a biometric record of where you go, when you go, and how often. You did not opt in. You cannot easily opt out. Transit systems feel like public space, but face-scanning turns every journey into a data event. The question is not whether the technology works. It is who controls the data, how long it is kept, and what else it gets used for.
