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.

Same, I literally scrolled back to the top to make sure it wasn't The Onion. How was this not bigger news?

Earlier quoted context omitted.

Authenticity validation could be completely external from Facebook, and if they gave a shit about your privacy they would not only be OK with it but even push for it. Many countries already have crypto-secure solutions for verifying their identity when submitting things like tax forms. Facebook just needs to start using them, but they won't, and it's obvious why.

No. This is the absolute wrong direction and would likely help push for a Government Internet ID. This would complete destroy online anonymity.

The US isn't the world. "Government Internet IDs" already exist, and there is nothing inherent in them existing that eliminates online anonymity, it just removes it on Facebook (which is exactly the point).

> and it's obvious why. Because most countries don't have crypto-secure identity verification, which means Facebook would still need something like this? I suppose they could contract out to Experian (or other local providers) and ask you to answer some questions from your credit report, but I'm not sure that's really a good solution either.

I thought it was clear enough that I mean't that it's obvious why [Facebook will never implement it even in countries where it already exists]. It's not in their interest to do so, because it's not in their interest to protect the privacy of their users.

Oh boy, what's bound to be another thread full of "delete your Facebook", the new and improved "I don't own a television" statement. Good for you, some of us actually appreciate the utility value from having a place to plan events and ensure people actually see that sort of thing. That said, this is a completely nonsense "solution" when there's plenty of other ways to perform verification that don't do double duty of…

Maybe you're being downvoted because this statement is just as cliché, if not moreso (given the amount of FB users vs non FB users) than the "delete your FB" cliché

I'd love to hear more about this.

Numerous systems that scrutinize IP-based geolocation information already throw up additional security checks when detecting changes.

Personally I welcome it, especially when banks do it. It's low-hanging fruit TBH. It massively fucks with those using VPN or Tor but I'm fine with that.

That's actually a pretty funny line given the current political situation in the US.

If it can't be fooled by a picture found online (but not uploaded to facebook) then that must mean facebook is indexing images across the internet and analysing all the faces they find... and if it can, what's the point (edit: from a user point of view)?

You really ought to read the book https://en.wikipedia.org/wiki/The_Circle_(Eggers_novel) I hear the movies crap, but the book is perfect.

Yes, the movie is really crap. Didn't know it was based on a book. Will look forward to read it. Thanks.

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.

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.
