I see blockchain-verification hype all over the place, and no-one's ever been able to convince me of how it would actually work in situations like this. Could you elaborate? How would you differentiate between "a 'legitimate' video that has been taken by a camera" and "a video that has been edited, and then had its provenance metadata edited to look like it is raw"? Given that there cannot possibly be any consensus p…
One thing you could do is have the camera hardware sign the raw image, then make a zero knowledge proof that says original photo was signed by real hardware, and then the only edits applied to it were simple things like cropping, changing colors etc Seems reasonable to coordinate the updates with a blockchain (though not necessary for use cases where you trust the platform / coordinating entity). Disclaimer I work at…
So like most solutions involving blockchains, no blockchain is actually required.

#13It would be really cool if it actually worked. Saw the recent videos and they are pretty much all a mess.
Anyone knows of something like this that works? Links? Thank you.

#14Yeah this deep fake is flawed enough to be amusing. But I know we're probably only 1-2 years away from producing extremely convincing deep fakes at a whim. In my mind, blockchain is the only thing that can counterbalance this tech. We need blockchain signed photos and videos to ensure authenticity.
Sigh... why is blockchain the only answer? Blockchain or any signing system, PGP, shared key, is only as good as the person/entity signing it. Who will perform that signing that you trust... CNN? Fox News? Google? THE US GOVERNMENT?!
Isn’t that the whole point of blockchain? A distributed ledger with no central authority so no single entity has the power to manipulate the history...

#16There's a huge and qualitative difference between the example video and the 'recent videos' below.
The example video shows the face being stretched mostly around the mouth, and without extreme or sudden changes. Sure, it looks fake, but it seems coherent. It's almost the kind of thing a human would make in a comedy setting. But in the generated videos below, I see a lot of the issues we often get with generative models -- eyes or mouths flickering in and out of existence, a disappearing neck, parts of the background getting mixed with the face, etc. Sort of nightmare-ish, but not at the level of deep-dream dog-worms from 2014 or whenever.
Were these even from the same method? Or is there some about the user-submitted photos that meaningfully differs from those used during training?

I think it is being hugged to death atm, can't load it either.

What stops me from signing my own deepfaked video and putting that on the blockchain?
What stops me from writing a check to myself and cashing it?
I remember a friend doing that. More funny a friend wrote I owe you $5 and deposited and took out $10 the minimum allowed.
What happened was that person lost the ability to deposit and withdraw.
There is a level of trust but things will catch up to you.

Any public open source blockchain. Whichever one the market rallies around, probably Ethereum. Because it's a consistent point of reference. The apps / phones could sign using zero knowledge proofs, so you don't have to give away personal details to verify.
At the very least this needs to be done with public figures in particular, since a convincing fake video could invoke a riot or cause a war.
