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

- colonelspace 2y agoThis 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".
