Blur tools for Signal: if you take or edit photos of crowds or strangers with Signal, you can use our face blur tool to quickly hide people's biometric face data.

You can then export the photo from Signal if you want to post it publicly.

I recall a story of a pedophile being caught because they posted pictures using a radial warp on the face. It wasn't too hard for enforcement to code a filter that undoes the radial warp, and instantly saw the original photo to identify and lock away the creep.

A warp doesn't technically lose the information, it merely displaces it. A good blur algorithm on the other hand will lead to loss of information.

This would demonstrate it well with physical concepts
