Laws can help, but I'm most concerned with states leveraging this to influence foreign campaigns.

There will be a time when the Trump "grab them by the you know what" style scandal will just be met with sceptism.

Where do you go when even video evidence can't be seen as the truth?

The devices need to cryptographically sign the original video with keys stored in some kind of Secure Enclave

If the video is edited or comes from a source that doesn’t have trusted keys then it’s no better than some random tweet

This is just a certificate of authenticity that one either trusts or not, based on whatever one knows about secure enclaves, cryptography, or the device/person issuing the key/certificate.

I think the reality is that photographs and video are now like text, you trust the source or not.

I can write about Cleopatra's ability to snowboard and play Xbox, or I can make a photo with the caption "Cleopatra doing a 1080", and now I can make a video of it (probably).

I can also give you a certificate/key/blockchain whatever to prove it's "valid".

And then someone takes the camera and points it at a screen showing an image of their choice. The analog hole cuts both ways.
