I have a newborn at home, and like every other parent, we take thousands of pictures and videos of our newest family member. We took pictures of the very first baby-bath. So now I have pictures of a naked baby on my phone. Does that mean that pictures of my newborn baby will be uploaded to Apple for further analysis, potentially stored for indefinite time, shared with law enforcement?

No, it doesn't work like that.

If you don't choose upload to icloud, no upload to apple at all.

If you do choose icloud upload (most do), they were being uploaded already and stored and may be available to law enforcement.

If you do upload to icloud, NOW they will be screened for matches with "known" images in a database, and if you have more than a threshold number of hits, you may be reported. This will happen on device.

Apple will also scan photos in their cloud system as well from what I can tell (though once on device is working less should land in cloud).

Note that it is HIGHLY likely that google photos / facebook / instagram and others will or are already doing similar scanning and reporting. I've heard millions of reports go in a year.

It's worth reading this, which is basically the only good reporting I've seen on this topic: https://daringfireball.net/2021/08/apple_child_safety_initia...

There are legitimate things to be concerned about, but 99% of internet discussion on this topic is junk.

Arent the perceptual hashes based on a chunk of the image?

I wonder what the false positive rates are for:

- A random image against the DB of perceptual hashes

- Images of a baby's skin against the DB of perceptual hashes

It seems like the second would necessarily have a higher false positive rate: similar compositions (contains baby's skin) would more likely have similar chunks. Is it just a little higher or several orders of magnitude higher?

I know hash collisions are rare, but wonder how much rarity of collisions decreases with perceptual hashes.

Unless those pictures are also in the NCMEC database, there won’t be a match.*

* As addressed in the comments below, this isn’t entirely true: the hash looks for visually similar picture and there may be false positives.
