If you want to bust online sharing rings, you don’t need to build a mass-scale image recognition system that would make Xi Jinping jealous. Just have your agents make some fake accounts and hang out in the wrong part of the web.

The fact that your systems *are recognizing so many of these images* is a good indication that either (1) they’re misfiring, or (2) your detection systems aren’t posing much of a deterrent.

Keep in mind that virtually every image recognition filter can be evaded by using a simple archive or encryption utility, and people aren’t even bothering to do *that*. So clearly you’re not achieving much of a deterrent effect.

I feel like we’re heading towards a world where the bad guys can stay safe with WinZIP.

Someone disingenuous here: any remotely competent scanning tool scans within compressed archives, and it is easy conceptually to include a set of default passwords.

I can't overstress the importance of talking to the people doing this stuff rather than mocking it from first principles

I really would like to talk to them. The problem is that up until the week of September 30, 2019, nobody told us that we were going to need to deprecate e2e encryption at major providers in order to support these tools!

Really this is entirely about Facebook and the Federal government, with everyone else left as spectators. I suspect the people at NCMEC feel just as blindsided as the pro-encryption advocates by the sudden lurch in this debate

I would frame the question this way: who gets to make sudden, sweeping changes in encryption policy affecting societies around the world? Right now the answer is "Mark Zuckerberg" and that is an even worse answer than the Trump administration, which is a terrible answer

Who would you propose in his stead? William Barr? Xi Jinping?

Yes. But both William Barr and Xi Jinping together, for balance.

The serious answer is that we, as a society, had a lot of democratic debates about this. The solution we enshrined into law (see CALEA) allows providers to encrypt data. This was all pre-Zuckerberg, so he had nothing to do with it. That was our decision.

That "we" is the United States, but the policy has global effects
