To add to this, you can always /try/ deleting your facebook account and see if it's for you. It's not like facebook is a nightclub that will refuse re-entry once you leave or anything.

My account went inactive and eventually was disabled. To get back into the "nightclub" now, I must submit a copy of my photo ID to verify my identity. No thanks to the Facebook bouncer thugs guarding the entrance...

I had a similar experience, but submitted a picture of my congressman (who was standing in front of a billowing American flag) which was accepted without comment by Facebook.

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.

What do you have against identifying friends' profile images, of all things? Facebook already has them.

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.

While this totally blows my mind, I can see how those a decade younger might not bat an eye, they might have sent digital nudes in the past, or even have one on the phone. A decade younger than that (late teens), and they might be so impatient about having to upload a digital nude, they just wonder why you can't just use one of the ones they sent last week. The difference in how the generations view technology and digital exposure in vast. "Sexting" came into the public consciousness as a common term almost a decade ago, but that's just when it was publicly popularized.

I mean, I consciously think about every time I actually give a close approximation on my age in a public forum (like I did above), and make a call on whether it's needed or not. I feel like a dinosaur because of it sometimes, but I also feel like there's only so much privacy you're allotted, and once it's lost, there's really no getting it back. :/

In context of Zuckerberg’s “They trust me, dumb fucks” comments, the invitation to upload nude photos seems especially alarming.

If one of my friends identified me in a photo to facebook, I would not be happy about it.

I generally ask everyone who knows me not to upload photos I'm in to facebook at all beyond what's already there.

Is there any precedent for recovering individual training items from a model trained on 100m+ examples?

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 hardly PII

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".

Under the EU GDPR (eg https://www.eugdpr.org/) it appears that they'll need explicit consent to retain the data (all of it, anything related and traceable to the person) and users will both have a right to view it and to have it deleted.

No, not really. There are not many of photos of me on the web and any that are were taken from a distance and too low res to id me. I've been stingy about that for a long time. FB doesn't have my phone number and I disabled the email address I used to sign up. I delete all my cookies often and use different browsers and turn off and reset my modem to get a new IP address. I have no apps on my phone, don't use iCloud,…

>don't use the native "Contacts" app, I made my own for that. That's a good idea. You could then grant other apps permission to see your contacts, but have the app optionally return fake or empty data.

This. Fake data should always be returned, unless explicit permission is granted for real data.

misrepresents the idea of the service. It's supposed to tackle the 'revenge porn' issue. If someone sees their own nudes show up on facebook, they can send a picture to facebook, which I assume get's fed into an image detection service that then tries to remove the already circulating nudes automatically.
