They could make it difficult to open up the camera and extract its signing key, but only one person has to do it successfully for the entire system to be unusable.

In theory you could have a central authority that keeps track of cameras that have had their keys used for known-fake images, but then you're trusting that authority not to invalidate someone's keys for doing something they disagree with, and it still wouldn't prevent someone from buying a camera, extracting its key themselves, and making fraudulent images with a fresh, trusted key.

Pics XOR it didn’t happen

Bobs or vagana

People act like this hasn't been a thing for over a century...

if it was up to me, you'd motherfuckers stop coming to me with fabricated evidence out.

I’ve been thinking that it would be fun to take a 100% real photo of a stack of real hands from the exact right angle that it looks like a mutated abomination generated by some stupid AI.

Biometrics should be usernames, not passwords. Fingerprints, irises, faces, vocal patterns, all of it, no matter how good it is, only identifies the person trying to enter/use something and is somewhat easy to steal without their knowledge.

If you want true security you still need to ask for a passcode that only the now-identified user will know.

And yes, it is still possible to intercept the passcode at the moment that the user interacts with the locking mechanism, but that is completely different from grabbing it when they're randomly walking down the street, etc.

(Edit to add: I didn't think this needed to be explained, but I'm not saying biometrics should replace usernames, I'm saying they shouldn't have replaced passwords. And yes, you can still use biometrics in the authentication process to identify that it's you, i.e. your username, but you still need a password.)

Conservatives are already starting to claim that legit photos and videos are AI, like Harris' crowds.

It kind of makes me want to go live in a shack in the woods, grow a garden and live out the rest of my days growing my beard and writing increasingly more obscure poetry until it gets posthumously published after my death.

Vegetables and Trees are real at least.

Very true. It's the immediacy of it that struck me this morning.

If I make a post telling you that I met Elvis Presley as an old man and you respond with "Pics or it didn't happen". I can literally post a reply to you within a couple of minutes (If I knew where to go) of me meeting an elderly Elvis Presley. Whereas before I'd have to put some effort into it, and then respond a day later with my finished photoshop creation. The immediacy lends it credibility in the way that traditional photo manipulation didn't.

It's depressing.
