In the days after the US Department of Justice (DOJ) published 3.5 million pages of documents related to the late sex offender Jeffrey Epstein, multiple users on X have asked Grok to “unblur” or remove the black boxes covering the faces of children and women in images that were meant to protect their privacy.

Are these people fucking stupid? AI can't remove something hardcoded to the image. The only way for it to "remove" it is by placing a different image over it, but since it has no idea what's underneath, it would literally just be making up a new image that has nothing to do with the content of the original. Jfc, people are morons. I'm disappointed the article doesn't explicitly state that either.

The black boxes would be impossible, but there are some types of blur that keep enough of the original data they can be undone. There was a pedofile that used a swirl to cover his face in pictures and investigators were able to unswirl the images and identify him.

With how the rest of it has gone it wouldn't surprise me if someone was incompetent enough to use a reversible one, although I have doubts Grok would do it properly.

Edit: this technique only works for video, but maybe if there are several pictures of the same person all blurred it could be used there too?

Several years ago, authorities were searching the world for a guy who had been going around the world, molesting children, photographing them, and distributing them on the Internet. He was often in the photos, but he had chosen to use some sort of swirl blur on his face to hide it. The authorities just "unswirled" it, and there was his face, in all those photos of abused children.

They caught him soon after.

They couldn't do that from one photo though, they'd need several examples all believed to be the same guy. A swirl like that preserves some of the information and you can reverse it, but the lost data is lost. Do that for several photos and you can get enough preserved bits to piece something together.

Same idea for some other kinds of blurs or mosaics. Black boxes, not so much - you e got no data to work with, so anything you tried to reconstruct would be more or less entirely fantasy.
