Swiss scientists have found that the simplest, cheapest and most effective way to hide from surveillance cameras is to do makeup.

In order for the plan to work, you should use the services of a professional makeup artist, say scientists. Face recognition systems typically respond to facial features such as eyes, nose, chin, and jaw, as well as to recognize skin texture and blemishes on the face.

Therefore, the system can be deceived, for example, by adding wrinkles and bags under the eyes. Or you can change the facial features by contouring. To fool the cameras, they usually use baseball caps and accessories like glasses, hats, wigs and overhead beards. But algorithms have already learned to deal with such tricks.
