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.
