There was some pytorch software called "enhance", i.e. ./enhance <image> [options] and you could take an image that someone took of their unpowered tv across the room and pull out a high resolution image of their face from the reflection in the matte-ish surface.

I used it on reddit to convince people it was unsafe to post any images of that sort. It seemed to work for about 6 months.

There's magic in image enhancement, but I don't know that ridges and valleys of a fingerprint are there, yet. I don't even know that "this specific person is scared that they leaked their face in a way that is recognizable to them" even scales to "never upload anything" - it could be this sort of news is programming the population that computers can tease out identities with any and all leaked information, pictures, audio, etc.

Heck, a decade and a half ago there were claims that governments could narrow a search for an audio file upload based on the deviation from 60hz on the power line noise - in an audio recording.

So who knows?
