I really don't see how this is going to end well, there could be perfectly innocent photos on someone's phone of their own children doing perfectly normal things that kids do. Like a kid running butt naked around the house, or a photo of something like a rash that is sent to a nurse friend for advice on what it is etc. I'm all for protecting children from being abused, but how are they going to filter what is normal…

Scan for child abuse today; scan for wrong-think tomorrow. I'm liking the idea of Graphene OS more and more each day... or just going phone-free entirely.

Then they could send you the new image and fuck up your life.
Ah, the classic 'think of the children' approach to increasing surveillance. If you're opposed to it, what are you, a nonce?

Now that CSAM detection is being deployed to user devices including those previously sold without it, there's a motivation to circumvent/block it. Unless Apple is doing CSAM scanning 100% inside a 100% secure processor, eventually someone will figure out the specifics of the current perceptual hash algorithm. There are already methods to make perceptual hash collisions. All it takes is one security researcher to publish a tool that creates millions of false-positives for the current dataset/model used by Apple & others to be useless.
Sure eventually they will improve the model/dataset but it just starts a cat & mouse game between Apple/Governments & honest citizens/users which actually benefits the people committing these crimes.

I am sure, presumbly in a sane world, computer scanning is only the early stage of the process, human will be invovled to make final judgements and decisions.
