To be clear, this is continued enforcement for years-old regulation. The feature is only enabled in the US where it is required.

The implementation is changing from cloud-based matching (which requires photos to be readable by their cloud infrastructure) to local based matching with threshold tokens (which would allow them potentially to be in compliance while making the system E2E encrypted w two additional key release mechanisms (key escrow via separate audited HSM systems, the given threshold disclosure of the image encryption key)

such a long sentence to say "backdoor"

Aka not E2E and therefore something that Cook should face a fraud charge for saying it is.

Apple needs to make it true e2e yesterday, and tell the FBI that they can either approve of it, or never use an iPhone again.

I’m the one saying it is, not Apple.

Could you point to the regulation that requires this?

See the “Federal CSAM Law” section here:

https://cyberlaw.stanford.edu/blog/2020/01/earn-it-act-how-b...

> Section 2258A of the law imposes duties on online service providers, such as Facebook and Tumblr and Dropbox and Gmail. The law mandates that providers must report CSAM when they discover it on their services, and then preserve what they’ve reported (because it’s evidence of a crime).

The law doesn't require them to actively go around scanning for it.

They’re scanning for it as it enters their system. It’s only scanned if it’s set to go to iCloud.

Yes, but then there's a way to upload it in plaintext. That's the backdoor. That can, and will, eventually be used to exfiltrate any file, anytime, whether it would be going to the cloud or not.

It does set a terrible precedent, but it's possible this is a step towards E2E encryption on iCloud data; a way to comply with the law while preventing law enforcement from being able to subpoena other data.

Apple is being its usual cryptic self about this, which is once again breeding uncertainty, but I still have hope in the end this will work out.

Re:Apple’s new abuse prevention system: an antritust/competi... by noduerme on Saturday August 07, 2021 @02:39AM (#28096327)
Again though, what is the guarantee this is only going to be used to scan data uploaded to the cloud? If Apple has the ability to exfiltrate data from a phone at whim, they lose any deniability or leverage they still have with authoritarian regimes that want all the data on a phone. It's not just a terrible precedent, it's a dangerous piece of malware.
Re:Apple’s new abuse prevention system: an antritust/competi... by dwaite on Saturday August 07, 2021 @05:45PM (#28102140)
They of course have the ability to exfiltrate data, they created the hardware and OS.

However since this is part of the opt-in iCloud photos sharing mechanism, it doesn’t appear they have started to exfiltrate data without consent.

I don't in know why you're assuming they have a backdoor built in already. The whole point is that they don't, but they're going to add one.

Re:Apple’s new abuse prevention system: an antritust/competi... by dwaite on Sunday August 08, 2021 @01:36PM (#28108473)
I don’t count this as data exfiltration because it only releases data if you are doing iCloud photos sync, which is opt in. iCloud photo sync has also always been recoverable on the server by government request.

So they have always been one software update from non-opt-in data exfiltration and remain so.

“ which would allow them potentially to be in compliance while making the system E2E encrypted …”

Apples system is not E2E encrypted if a local program scans files prior to upload.
