So I had researched it a while ago and don’t recall having found anything effective and non-suspicious to protect from public camera mass survaillence in cities and the like. Is there anything that is a good option for that yet, and if so, could you point me toward it?
IR blocking sunglasses are the simplest and most practical solution.
Facial recognition systems compare the distance ratios between your eyes and nose primarily. Hiding your eyes is very effective towards fucking that up. A mask alone is typically not enough.
Sunglasses alone are not enough either. Modern face recognition tech is way better than just distance ratios
