It's time we all invest a bit of our time to provide real open and benevolent alternatives to facebook, google, amazon, and all the rest, because they're steering internet toward an orwelian nightmare.

What recovery? You're uploading your pic via your account. It is already associated with you.
As I understood it you are making the argument that they will have information about you from uploading this picture even if they delete the actual picture. I'm genuinely asking if it is possible to recover an individual training example from a model which is shown vast amounts of data. I'm only aware of being able to recover stuff like this - https://ars.els-cdn.com/content/image/1-s2.0-S08936080173020... which is h…
This is just as much PII as your fingerprints. Fingerprint based devices store metadata not images. I can't look at a fingerprint and connect it to a person, but a machine can. Similarly the output of a NN designed to recognize people will be useful for validation. Otherwise biometrics would not work.
Remember if they are using your photo as training data the NN is going to learn you vs someone else or it's useless. If they can find you in any photo that's as effective as handing a person the uploaded photo and giving the same task.
>> “Please upload a photo of yourself that clearly shows your face.

I assume this means that the photo itself is deleted but a one-way hash of it created to test against later. However, if I change one pixel of a picture of my face, A, to produce a new picture of…
I'm not sure how it identifies a human from a bot though.
I was recently locked out of my FB account. The only way to unlock it was to identify my friends' pictures. Apparently sending me an e-mail was too much trouble ... Haven't been able to log in since, as I refuse to partake in that sort of bullshit. Can't say I miss it.

I don't see how that makes it better.
Presumably, you would do this after Facebook already has a copy of the nude -- uploaded by the attacker/malicious ex. If you want Facebook's computers to automatically take down any copies of the photo, yes, you're going to have to trust them with a copy of it. Automated DMCA takedowns of copyrighted music and movies work in very much the same way.
No. They could have you compute a fingerprint locally without uploading the image itself, preferably through some audited open source software, without auto-updates. They only don't do that because they want to guard their image hashing as corporate secrets.

I uploaded a cropped/mirrored picture of Jack Nicholson in the Shining. After 48 hours the account was working again, no idea what happens in that process.
It's already nontrivial to create fake Facebook accounts. For those serious about it, who already deal with IPs and mobile numbers, I can't imagine that creating novel photorealistic faces would be all that problematic.

FaceID is unique in the sense that it's supposed to be on-device only in the form of an ASIC coprocessor.
You can't tell with closed source. Anyway, what about "iCloud backup"?
