Tricky. Sending them all of your potentially leaked embarrassing photos so that they can store them and prevent them from leaking out. If they get hacked now someone has a lifetime supply of blackmail material. Not clear if the cure is better than the ailment.

From the fine article:

"We store the photo hash—not the photo—to prevent someone from uploading the photo in the future. If someone tries to upload the image to our platform, like all photos on Facebook, it is run through a database of these hashes and if it matches we do not allow it to be posted or shared."

This is insane. If they can fingerprint your images, why can't they provide a tool for processing the image and sending the fingerprint only? Can you imagine how big of a target a tailor made database of blackmail material linked to facebook accounts would be?

Ah, missed that, thanks. Yeah I guess you have to trust that part. I guess I'm willing to believe that. Hopefully it's not like with Snapchat where everything get stored behind the scenes forever even though it "disappears".

Also, wonder if basing things on hash will make detecting slightly modified versions of that content almost impossible. E.g. IG / YT can detect if you upload content with a piece of music that's copyrighted regardless of how much you alter it, but this would be fairly primitive.

Is there a way for me to audit that the image is never stored? (No) It seems like that's a huge honeypot; someone compromises the "upload your naughty photos here" endpoint and has an endless supply of "non-consensual intimate images".

Edit: Thinking about it a bit, I'd be way more comfortable with the idea of the image hashes being computed on-device and only the hashes being sent to the server. This opens a different door of abuse (by essentially permitting individuals to ban someone from posting an image by uploading the hash of the image), but it's definitely preferable to encouraging people to send all their selfies to the privacy commissioner.

If you can send only the fingerprint, what stops you from uploading photos you are not in?

A better idea may be an uploading tool where you can obscure some parts for verification.

isn't nudity generally banned on facebook anyway? I didn't realise this would/could be an issue. Unless they're talking about private communications in eg. messenger.

Revenge porn isn't all about nudity. And this does cover Messenger (and Instagram). The point isn't to get an image taken down after the fact, but to proactively block it from being posted or sent in the first place.
