Didn't she possibly have previous partners?
Given all the zero day exploits on iOS I wonder if it's now going to be viable to hack someone's phone and upload child porn to their account. Apple with happily flag the photos and then, likely, get those people arrested. Now they have to, in practice, prove they were hacked which might be impossible. Will either ruin their reputation or put them in jail for a long time. Given past witch hunts it could be decades be…
This is really a difficult problem to solve I think. However, I think most people who are prosecuted for CP distribution are hoarding it by the terabyte. It’s hard to claim that you were unaware of that. A couple of gigabytes though? Plausible. And that’s what this CSAM scanner thing is going to find on phones.
I do not know as much about perceptual hashing as I would like, but have considered it for a little project of my own. Still, I know it has been floating around in the wild. I recently came across it on Discord when I attempted to push an ancient image, from the 4chan of old, to a friend, which mysteriously wouldn't send. Saved it as a PNG, no dice. This got me interested. I stripped the EXIF data off of the original…
Apple’s documents said they require multiple hits before anything happens, as the article notes. They can (and have) adjusted that number to any desired balance of false positive to negatives. How can they say it’s 1 in a trillion? You test the algorithm on a bunch of random negatives, see how many positives you get, and do one division and one multiplication. This isn’t rocket science. So, while there are many argum…

And what do you think the content moderation teams employed by Facebook, YouTube, et al. do all day?

They already do this for photodna-matched iCloud Photos (and Google Photos, Flickr, Imgur, etc), perceptual hashes do not change that.
I'm not familiar with iPhone picture storage. Are the pictures automatically sync'ed with cloud storage? I would assume (even if I don't like it) that cloud providers may be scanning my data. But I would not expect anyone to be able to see or scan what is stored on my phone. Incidentally, I work in computer vision and handle proprietary images. I would be violating client agreements if I let anyone else have access t…

I've also implemented perceptual hashing algorithms for use in the real world. Article is correct, there really is no way to eliminate false positives while still catching minor changes (say, resizing, cropping, or watermarking). I'm sure I'm not the only person with naked pictures of my wife. Do you really want a false positive to result in your intimate moments getting shared around some outsourced boiler room for…
