Does Apple have a legal or regulatory requirement to scan iCloud photos for CSAM? I poked around but didn't find a quick answer. Reading through the two linked PDF's, I got the impression that they're aiming to use cryptographic techniques to meet a (possibly self-imposed) requirement to scan for CSAM while revoking their current ability to decrypt photos stored in iCloud. I guess they may want to revoke this ability so that they can no longer be compelled to hand over customer's photos except those for which the requirements of this new system are met. I guess if it results in an increase of the privacy of iCloud content, that's nice as far as it goes. But it does skeeve me out to be reminded that my phone can (and does) paw through my stuff.
