Facial Recognition in Public
Facial recognition, which is arguably the most controversial biometric technology today, maps the mathematical geometry of the human face to identify individuals in public. Modern biometric search engines can process up to 10 million faces per second, but their real-world accuracy drops significantly in crowded public squares where lighting and camera angles change constantly.

In my opinion, tracking citizens without their explicit consent poses a massive threat to democratic freedom. If police forces deploy these highly flawed systems to monitor cities, they will silence public dissent and eliminate our basic right to navigate public spaces anonymously.
Is our information really safe with facial recognition?
