The scanning matches against CSAM hashes provided by NCMEC - the fear is that NCMEC will be pressured into including hashes of non-CSAM material that USGOV want to track as well (say MAGA images for the current administration.)

(One counterpoint to this is that PhotoDNA has been used for scanning cloud images using NCMEC-provided hashes for a decade now and this slippery slope doesn't seem to have happened yet.)

View on HN

this is a very weak argument. The MAGA crowd has been posting images all over social media.

My understanding is that there is a threshold that needs to be met, and then an Apple employee with a very difficult job will need to confirm the image. So even if NCMEC get pressured, I don't see what the result can be.

That Apple employee (assuming the role doesn't get contracted out) has no incentive to protect you or me. But they'll absolutely err on the side of caution to protect their own livelihood.

and what's the next step? FBI breaks down my door because I said something bad about Biden?

Something like that is unlikely to happen because the US is not — for now — an authoritarian state.

Replace “FBI” and “Biden” with their equivalents in various other countries and yes, it’s absolutely plausible.

There is also international perspective: once this mechanism is in place, forced by US, it will become normalized in several years. Then China will have much better leverage to implement their own scans. Once China does it, every powerful state does it. And after that every third world hole will scan for everything.

what's stopping them from doing that now?

Because Apple does not currently have code for scanning local devices for illegal images, and would have to implement it, which is a much higher bar than having already implemented it and just needing to add a few hashes to a database.

but they do have it. pretty much all image hosts are already doing it as well
