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.
Hmm. Thats a neat feature. I love signal.
Always heard blurring was ineffective and that solid colored boxes should be used instead
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.
They had to ask adobe if i recall correctly. Which does mean it isnt as easy as it sounds to reverse engineer (since adobe developed it, they obviously knew how to do it)

Depends on how the blur is implemented…
I remember something like this on the Underhanded C Contest.
(It was for blacking out parts of an image.)
