They have no access. It is end-to-end encrypted with new system. That is the whole point of on-device scanning. It is not next step, it is already there.
- kristjansson 5y agoIt works if the photos are encrypted such that Apple can’t access them. Hence the wonky design. They haven’t announced that photos will be E2E encrypted.
- nicce 5y agoThey did… just read the specs. There are many pdf:s on the bottom. They failed the PR truly. https://www.apple.com/child-safety/ https://www.apple.com/child-safety/
- kristjansson 5y agoThat’s not my interpretation of the first party descriptions of the CSAM system. Clearly it works if photos are encrypted; nothing implies they’re using that capability yet. If that were the case, this would not merely be a PR mess but PR malpractice of an entirely other, novel kind.
- nicce 5y agoThe system is complicated, especially the PSI paper. But it is clear, that it is designed to run on encrypted images, there is choice to run without it.
- iakov 5y agoSo it doesn't mention that anything is actually E2E encrypted right now, does it?
- nicce 5y agoIt does if you try to understand that system. CSAM scan on-device won’t work at all without that encryption part.
- brokenmachine 5y agoOf course it will. It's only the vouchers that are encrypted.
