Can you point to a single instance of that happening where it was due to a false positive?

If we reduce it down to "someone being accused of a crime but later being found innocent", then there are several, and when it comes to sex crimes, the accusation alone is enough to ruin someone. People don't care about minor details such as the fact that the person was later found innocent. To them, it's the same as getting off on a technicality.

Ok yes - now then, PhotoDNA has existed since 2008. When has what you’ve described ever happened?

PhotoDNA relies on perceptual hashing?

In a proposed system that has yet to be deployed?

This has already existed in PhotoDNA since 2008. This is not new

Examples of on-device scanning via PhotoDNA?

People’s photo libraries are scanned. The result is the same.

Only if you’re putting your stuff in the cloud. There’s a big difference between my files on my computer and my files on someone else’s computer. Or at least there should be, IMO.

Yeah, only if you're putting your stuff in the cloud. The result is the same.

But that's deployed in a very different way which makes the concerns being discussed much less likely to happen.

Specificly the person doing the scanning already has access to photos and can double check the results without having to sieze the device, a rather public process.
