Was listening to the radio earlier and a discussion of deep fake videos came up. Does anyone know if there is a standards group working on integrating video with PKI, like HTTPS? I'm thinking of encrypted watermarks that browsers, or even social media sites could verify. While a lot of people wouldn't care, it might give a chance for media outlets to be able to stamp their videos and feeds with their certificates, and be able to verify the authenticity wherever the video goes.
If something is already out there, and I've just missed it, please let me know.
