I'm not looking at is a token per se. I'm mainly interested in a Decentralized ID, which could represent an organization, like FOX or CNN. Nevermind the political biases of those orgs. Each org can establish a DID that they publicly claim is theirs and they sign all their video footage with those DIDs. Theoretically an open source camera and microphone chip could also sign a MP4 or MP3 file in a verifiable way. So you've got different levels of authenticity verification. This is just to prevent someone from taking this AI tech and making it look like an anchor said something that they didn't actually say. The timestamp of signing a transaction on the blockchain is important for proving when something occurred.

PGP depends on a certificate authority, and is quite centralized in that sense. Blockchain allows multiple open standards to exist and to develop organically. AI will continue to evolve and it's important that verification tech evolve along with it in a open source manner. The blockchain community, especially with it's recent work and research on zero knowledge proofs, are more prepared to adapt to those changes. Their whole industry is based on establishing consensus in a permissionless way.

Again a decentralized ID is all well and good. An extension of PGP/GPG which as before, works great for this person signed this video.

The problem of deep fakes still exists. Deep fake isn't just about altering, it's also about creating whole new videos that didn't happen using the likeness of a person like in OP's link.

If I upload that, sign it with my decentralized ID, CNN and Fox picks it up and co-sign it with their decentralized ID. Great! My deep fake is in the wild picked up by millions all while being completely verified.

But that won't happen because no one would believe you irjustin. Right, isn't that the crux? Who do we trust?

(if you're thinking i can't just sign any random video, it's gotta be signed with my phone - don't worry let's go back to direct feed into the camera)

I'm not sure what else to say to help you understand that if you're not willing to take a hard look at your own solution then there's nothing I can do to convince you the block chain is really good at doing some things and preventing deep fakes is not one of them.

You're never gonna solve it with 100% veracity. But look, if irjustin smart contract got created in less than 24 hours and posted the fake photo or video with no prior reputation and also the video lacks hardware signatures then you've got the markers to establish trustworthiness. That should give people enough reason to doubt it.
