Today it’s easy to recognize faces from camera footage taken in public. Whenever you leave the house, your movements can be tracked whenever a camera sees your face! Luckily, there are some ways to avoid this—at least for now.
Thanks to a branch of computer science called “machine vision“, it’s possible to create software algorithms that quickly match a face in a photo or video to one on file. Since modern cameras are so good and computers are incredibly fast, this can be done in real-time, even in large crowds.
Wait, how do they have a photo to match your face? Well, if you’ve ever put a photo of yourself on social media or a friend has tagged you in one of their photos, then it’s simple to scrape the internet for photos that have already been identified. Most likely by you!
