Summary for the lazy: - this is going to be out in ios15
- Apple will build and push a database of hashes with every update
- these hashes will be used to verify against the pics before they are uploaded to icloud and generate a "voucher"
- once a certain threshold of vouchers is passed, Apple will be able to decrypt the pictures in questions (all this discussion seems to assume Apple does not have access to icloud pictures - so maybe they are preparing to rollout full encrypted backups???)
- the crypto stuff is interesting
- the scary part is that there is nothing preventing Apple to do the same thing with other thing on your phone (assuming there is a way to generate a good enough matching hash - I can see how this could be easily extended to basically anything that's stored on the phone)
