Sure, it's possible, but that doesn't seem to have happened in the past decade of PhotoDNA scanning cloud photos to match hashes provided by NCMEC - why would it suddenly start happening now?

If it's happened, it's unlikely the public would know about it.

You really don't understand the difference in scale distributed sensor netwise between the two different capabilities do you?

Server centric is the primitive that gives you periodic batch. Client resident let's you build up a real-time detection network.

Also, as they say in the financial world: past performance is not indicative of future results. No one would have thought to do so because this step hadn't been done. Now that this step has been done it is an easier to sell prospect. This is how the slippery slope works.

What's the realistic difference here between "my phone scans the photo on upload to iCloud Photos" and "iCloud Photos scans the photo when it's uploaded"?

Latency of upload doesn't come into play here because the scan results are part of the uploaded photo metadata; they're not submitted distinctly according to Apple's technical description.

(And given the threshold needed before you can decrypt any of the tagged photos with the client side system, the server side scanning would be much more "real-time" in this case, no?)
