I have an idea to implement a badge that encodes the audio into a super low bandwidth stream with signing, then displays that stream as part of the video. It would tie a video stream to an audio stream to a signature. If the video is faked, the audio won't match, if the audio is faked, the signature won't match. The idea is anyone can attach the badge and be sure people know it's not deep faked.
