A bit off-topic, but the point on duplicate detection reminded me of a thought I've had while taking photos on trips, in a swarm of other people doing the same. I've always wondered how much of the ICloud's storage is taken up by duplicate photos across everyone's phones. How many petabyte would this be? Imagine swapping one person out for another, in the same exact location in an image. How many then?

Apple tried this, but The Internet got mad again: https://news.ycombinator.com/item?id=42584856

And for good reason, since this way you'd be poking your nose into other people's photo collection...

It's easy to imagine merging photos of people in the same scenic spot, but how about the photos of those people in the same hotel room bed doing whatever? :)

Again, in pure Apple style, they had SO MUCH complex math and proxies between them and the image detection system that there would be no way - mathematically proven - that they could see anything.

But the headline says "APPLE SPYING ON YOUR PHOTOS!!11" and that's it. Nobody bothered to spend 5 minutes reading the whitepaper. It was on-device CSAM detection all over again.
