Today, a prominent child safety organization, Thorn, in partnership with a leading cloud-based AI solutions provider, Hive, announced the release of an AI model designed to flag unknown CSAM at upload. It's the earliest AI technology striving to expose unreported CSAM at scale.

This seems like a potential actual good use of AI. Can't have been much fun to train it though.

And is there any risk of people turning these kinds of models around and using them to generate images?

[–] mspencer712@programming.dev 8 points 2 days ago

I think image generators in general work by iteratively changing random noise and checking it with a classifier, until the resulting image has a stronger and stronger finding of “cat” or “best quality” or “realistic”.

If this classifier provides fine grained descriptive attributes, that’s a nightmare. If it just detects yes or no, that’s probably fine.

[–] catloaf@lemm.ee 7 points 2 days ago

Nobody would have been looking directly at the source data. The FBI or whoever provides the dataset to approved groups, but after that you just say "use all the images in this folder" and it goes. But I don't even know if they actually provide real full-resolution images, or just perceptual hashes, or downsampled images.

And while it's possible to use the dataset to generate new images assuming the training data had full-res images, like I said, I know they investigate the people making the request before allowing access. And access is probably supervised and audited.

This is a great development, albeit with a lot of soul crushing development behind it I assume. People who have to look at CSAM or whatever the acronym is have a miserable job, so I'm very supportive of trying to automate that away from people.

[–] atomicorange@lemmy.world 1 points 2 days ago* (last edited 2 days ago)

Yeah, I’m happy for AI to take this particular horrifying job from us. Chances are it will be overtuned (too strict), but if there’s a reasonable appeals process I could see it saving a lot of people the trauma of having to regularly view the worst humanity has to offer without major drawbacks.

I think all CSAM should be destroyed out of respect for the victims, not proliferated. I don't care who is hanging onto this material or for what purpose.

[–] sunzu2@thebrainbin.org 4 points 2 days ago

This ain't about the victims... It never was, otherwise churches would NOT exist in current form.

This is about police and corpo state gaining power.

At this point how does it differ w/ generating AI powered CP? morons

[–] xionzui@sh.itjust.works 10 points 2 days ago (1 children)

Uh, well this one tells you if an image looks like it or not. It doesn’t generate images

[–] horse_tranquilizers@sh.itjust.works -1 points 2 days ago (1 children)

If it knows if an image looks like it it can generate something like it, one step further

[–] melroy@kbin.melroy.org 2 points 2 days ago (1 children)

Correct, this kind of software is trained on CP data. So such models can be easily used to generate CP instead of recognizing it, which makes them very dangerous indeed.

Same idea as the current models that are trained to recognized cars, these models can also be used to generate a car from noise as a starting poiint.

[–] xionzui@sh.itjust.works 5 points 2 days ago (1 children)

In pretttty sure you can’t just run it in reverse like that. There’s a whole different training and operation methodology you have to use to support generating images rather than simple text classification

It differs in basically being something completely different. This is a classification model, doesn't have generative capabilities. Even if you were to get the model and it's weights, and you tried to reverse engineer an "input" that it would classify as CP, it would most likely look like pure noise to you.

Generate porn, classificate output, result very young looking models.

[–] Railcar8095@lemm.ee -1 points 1 day ago (3 children)

So you need to have a model that generates CP to begin with. Flawless reasoning there.

Look, it's clear you have no clue what you're talking about. Stop demonstrating it, moron.

[–] JackbyDev@programming.dev 1 points 1 day ago (2 children)

Alright, I found the name of what I was thinking of that sounds similar to what they're suggesting: generative adversarial network (GAN).

The core idea of a GAN is based on the "indirect" training through the discriminator, another neural network that can tell how "realistic" the input seems, which itself is also being updated dynamically. This means that the generator is not trained to minimize the distance to a specific image, but rather to fool the discriminator. This enables the model to learn in an unsupervised manner.

Not CP, but normal porn and select on CP traits, moron

Not that I think you will understand. I'm posting this mostly for those moronic enough to read your comments and think "that seems reasonable"

[–] JackbyDev@programming.dev 0 points 1 day ago (1 children)

The model I use (I forget the name) popped out something pretty sus once. I wouldn't describe it as CP, but it was definitely weird enough to really make me uncomfortable. It's the only thing it ever made that I immediately deleted and removed from the recycling bin too lol.

The point I'm making is that this isn't as far fetched as you believe.

Plus, you can merge models. Get a general purpose model that knows what children look like, a general purpose pornographic model, merge them, then start generating and selecting images based on Thorn's classifier.

[–] Railcar8095@lemm.ee 1 points 1 day ago (1 children)

You can't merge a generative model and a classification model. You can run then in series to get a bunch of false positives/hallucinations, but you can't make it generate something from the other model.

[–] JackbyDev@programming.dev 1 points 1 day ago

When I said a "general purpose model that knows what children look like" I didn't mean the classification model from the article. I meant a normal, general purpose image generation model. When I said "that knows what children look like" I mean part of its training set is on children, because it's sort of trained a little on everything. When I said "pornographic model" I mean a model trained exclusively on NSFW content (and not including any CSAM, but that may be generous depending on how much care was out into the model's creation).
