Not clicking on that link, don't want my G account go poof

Yeah, seems like anyone clicking through is playing with fire. If the description is correct, posting the link is highly irresponsible. (It seems like the right thing to do would be to serve the content from a server the OP controls themselves.)

"Now you can block people in Drive. To prevent people from sharing unwanted files with you, ..." hahaha. What a coincidence, Google! So you got a hold of the neural hashes, and then used an error function and descent to generate images that match a 'hash'? It feels wrong to call them 'hashes' when they're so weak to pre-image attacks. They're not the same idea as cryptographic hashes at all. Also want to underline ho…

Some? Literally all are clearly based on pornography.

First is veg&butthole, then boobs, next is doggy style etc etc (edit: it seems the order isn't consistent. So I'm likely seeing different images then you.)

You can go through them all and see the original pornography if you look at the shapes. To me, it looks more like they started with the real images and tweaked them to make them artsy.

As far as I can see the claim made here is not correct.

Assuming the images do as claimed match the hash, they must also match the ‘visual derivative’ in order to trigger a match.

The system isn’t as easily fooled as is being claimed here.

These harmless generated images have a neuralhash equivalent to those provided in the NCMEC database submitted for testing. I repeat: Dont upload these harmless images to iCloud as Apple will assume its Child Porn (CSAM). Scripts were available on a GitHub repo but were removed because they may cause damage to others.

> Dont upload these harmless images to iCloud as Apple will assume its Child Porn (CSAM) This is not true. They may match the hash, but the will not match the visual derivative. The system is not as easily fooled as you think.

> The system is not as easily fooled as you think.

I would like to believe that is true, but the negative consequences of even generating a false-positive is enough to not attempt to upload any image.

I assumed that these are reverse engineered from legitimately illegal and problematic porn of known origin.

Not sure exactly how you'd go about doing it, but it seems like there might be a process for 'evening out' areas into solid color that maintains the hash? In which case you're running extensive image processing on illegal images and making variations from those very images.

More info on how this is done?

I've never used modern apple products, but I have a question on how apple cloud works: is it possible that simply sending these in a messenger software to someone who uses apple cloud for automatic backups could get that person flagged as a child pornographist?

No, messages and regular file backups aren’t checked for child porn and the online photo library has multiple checks and reviews to prevent any false flagging.

Don't forget how it started at Google.

Long before they claimed that they scan email for child porn, they made an email scanner to appease China, on a condition they will not target dissidents.

I think all remember how it went. Seeing their intimidation work, it only fired up the Chinese government, and led them to only increase their attempts at arm twisting, until Google clumsily pretended to "be tough" while still doing their last attempt behind the scenes negotiations, which, to their big surprise, got them banned overnight.
