because its scanning the content of the device, not what you did on the device. An iFrame full of CP downloaded from 4chan that fills the browser cache with CP just by visiting a harmless site would not go anywhere near Google Photos, Facebook messenger, etc etc It would trigger a scanner checking the browser cache for CP images. Those are just the obvious ways, by "rife" I mean there is any number of ways to get CP onto someones device without them knowing, unless the device itself is being scanned nothing would achieved by this. And if you dont think people are that messed up, check: https://en.wikipedia.org/wiki/Swatting https://en.wikipedia.org/wiki/Swatting

Good thing this system doesn’t scan browser cache, then. Unless you’re programmatically extracting photos from your browser cache and uploading them to iCloud, which would be a pretty impressive way to make sure you’re using up all your storage.

  Ok, here is something that happened that could have triggerd this: Back when I used WhatsApp I got a lot of nice photos from friends and family there. WhatsApp doesn't (at least didn't) have a way to export them but I could find them on disk and I had an app that copied that folder to a cloud service. Problem is this folder contained all images from all chats. Now I'm not very edgy so most of my pictures are completely non-problematic (in fact I don't know of any problematic ones), but once in a while someone will join one of your groups and post shock pr0n. I've long since stopped backing up everything since I use Telegram now and it allows me to selectively backup the chats I want. But I wanted to mention just one very simple way were doing something completely reasonable could result in an investigation of an innocent person.

But that’s not the proposed design. Browser cache isn’t getting advanced. It’s photos for iCloud. I’m not asking if people do bad things, I’m saying over and over again this is getting coverage on Hn and people are pointing to this hypothetical issue — yet this hypothetical issue has been possible for years on many more devices.

  As far as I have read its scanning any images and messages on the device, as well as text entered into Siri. So accidentally stick a w in your siri teen porn search and you'll be seeing https://www.apple.com/v/child-safety/a/images/guidance-img__eu6rk2abgp6q_large.jpg https://www.apple.com/v/child-safety/a/images/guidance-img__... If it was photos taken on the device there would be no existing hash for the image to match.

    Totally tangential, but i didn't realize that there were well-advertised "anonymous helplines for at-risk thoughts". I'm kind of curious about it as a pathology (what does "help" look like?), but I'm uneasy about even getting that in my search history

"Does this mean Apple is going to scan all the photos stored on my iPhone? No. By design, this feature only applies to photos that the user chooses to upload to iCloud Photos, and even then Apple only learns about accounts that are storing collections of known CSAM images, and only the images that match to known CSAM. The system does not work for users who have iCloud Photos disabled. This feature does not work on your private iPhone pho- to library on the device."
