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.

[-] usualsuspect191@lemmy.ca 50 points 7 months ago* (last edited 7 months ago)

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.

A swirl is a distortion that is non-destructive. Am anonymity blur averages out pixels over a wide area in a repetitive manner, which destroys information. Would it be possible to reverse? Maybe a little bit. Maybe one pixel out of every %, but there wouldn't be any way to prove the accuracy of that pixel and there would be massive gaps in information.

Swirl is destfuctive like almost everything in raster graphics with recompressing, but unswirling it back makes a good approximation in somehow reduced quality. If the program or a code of effect is known, e.g. they did it in Photoshop, you just drag a slider to the opposite side. Coming to think of it, it could be a nice puzzle in an adventure game or one another kind of captcha.

[-] Barracuda@lemmy.zip 4 points 7 months ago

You're right. I meant more by "non-destructive" that it is, depending on factors like intensity and known algorithm, reversible.

[-] floquant@lemmy.dbzer0.com 8 points 7 months ago

Yeah, but this type of machine learning and diffusion models used in image genAI are almost completely disjoint

They think that the AI is smart enough to deduce from the pixels around it what the original face must have looked like, even though there's actually no reason why there should be a strict causal relationship between those things.

[-] Pyr_Pressure@lemmy.ca 7 points 7 months ago* (last edited 7 months ago)

There was someone who reported that due to the incompetence of whitehouse staffers, some of the Epstein files had simply been "redacted" in ms word by highlighting the text black, so people were actually able to remove the redactions by turning the pdf back into word and removing the black highlighting to reveal the text.

Who knows if some of the photos might be the same issue.

[-] KyuubiNoKitsune@lemmy.blahaj.zone 15 points 7 months ago

That's, not how images like png or jpgs work.

[-] unmagical@lemmy.ml 5 points 7 months ago

In the case of what wound up on Roman Numeral Ten (formerly twitter) that's correct, but given the actual PDF dump from the gov, if they just slapped an annotation on top of the image it'll be possible to remove it and reveal what's underneath.

[-] KyuubiNoKitsune@lemmy.blahaj.zone 4 points 7 months ago

I didn't realise that they released the images as pdfs too.

[-] unmagical@lemmy.ml 4 points 7 months ago

It was simpler than that. You can just copy the black highlighter text and paste it anywhere.

"Hackers used advanced hacking to unredact the Epstein files!" - Actual headline. The "hackers" did just Ctrl+A, Ctrl+C, opens word processor, Ctrl+V

How do these AI models generate nude imagery of children without having been trained with data containing illegal images of nude children?

[-] AnarchistArtificer@slrpnk.net 59 points 7 months ago

The datasets they are trained on do in fact include CSAM. These datasets are so huge that it easily slips through the cracks. It's usually removed whenever it's found, but I don't know how this actually affects the AI models that have already been trained on that data — to my knowledge, it's not possible to selectively "untrain" models, and they would need to be retrained from scratch. Plus I occasionally see it crop up in the news about how new CSAM keeps being found in the training data.

It's one of the many, many problems with generative AI

[-] RedGreenBlue@lemmy.zip 15 points 7 months ago

Can't ask them to sort that out. Are you anti-ai? That's a crime! /s

[-] Senal@programming.dev 6 points 7 months ago

Easy answer is , they don't

Though that's just the one admitting to it.

A lightly more nuanced answer is , it probably depends, there's likely to be some inference made between age ranges but my guess is that it'd be sub-par given that it sometimes struggles with reproducing images it has a tonne of actual data for.

Won't work and if it does work, the resulting image has little to nothing to do with the original.

Source: I opened a badly taken .raw file a few thousand times and I know what focal length means, come at me.

I am so glad I no longer interact with that dumpster fire of a social network. It's like the Elon takeover and the monetization program brought out every weirdo in the world out of the woodwork

I doubt any of these people are accessing X over Tor. Their accounts and IPs are known.

In a sane world, they'd be prosecuted.
In MAGAMERICA, they are protected by the Spirit of Epstein

[-] clay_pidgin@sh.itjust.works 10 points 7 months ago

What crime do you imagine they would be committing?

I don't know what they hope to gain by seeing the kid's face, unless they think they can match it up with an Epstein family member or something (seems unlikely to be their goal).

[-] aeration1217@lemmy.org 15 points 7 months ago

Sounds about right for x users

[-] melsaskca@lemmy.ca 13 points 7 months ago

Of course they are. Who's left on Twitter nowadays? Elon acolytes?

Put all these creepy bastards on a publicly viewable list.

[-] cley_faye@lemmy.world 7 points 7 months ago

Didn't they already do that in their public posts or whatever? They don't care.

And gruk, being trained on elons web history, doesn't need to be asked to find, let alone unblur said images.

[-] anon_8675309@lemmy.world 5 points 7 months ago

People are so fucking sick.
