Last paragraph of the article: "The new authentication scheme is the second in recent weeks that relies on photos. Earlier this month, Facebook asked users to upload nude photos to Facebook Messenger, as part of an effort to prevent revenge porn. Facebook said it would use the nude photos to create a digital fingerprint against which to compare future posts." Wait what? I had to check whether today was April 1st.

Can someone explain if / how this prevents someone from just changing a single pixel and thus circumventing the hash? Are they using some kind of probabilistic hashing? Or are they just relying on the offenders to not be so clever?

That only applies to Europe. The question is whether the data is valuable enough to Facebook to spend the time to add `if (europe)` to their code.
Or indeed care about the law enough to bother before they're fined for doing it. After all you'll need to prove they didn't delete the data first!

That's so ridiculous it could have been written by The Onion. Facebook has absolutely no businesses to store nude pictures of their users.

You can't tell with closed source. Anyway, what about "iCloud backup"?

Yeah it may be a binary dump, but it's now decrypted and understandable.

Not sure how I feel about it still, but this article doesn't really accurately portray the service. From the source linked by the Wired article [1], this is specifically intended to prevent a nude photo from being shared maliciously when a user has reason to believe that it will be. They then voluntarily upload the image to Facebook which uses the digital fingerprint to prevent it from being reposted either in its or…
I don't see how that makes it better.

Apple doesn’t backup TouchID or FaceID data to the cloud (just as they don’t backup your iOS device passcode). You need to set up each device independently. https://images.apple.com/ca/fr/business-docs/FaceID_Security...

I'm pretty sure Facebook already has plenty of training data of faces
Excuse me. The issue is biometrics. "We'll delete the picture" =/= "we'll delete the control points and features extracted from your pics".
