Politicians and anyone at deepfake risk wear a digital pendant at all times. Pendant displays continually rotating time-based codes. People record themselves using video hardware which crypto graphically signs output.
Only a law/Big 4 firm can extract video from the official camera (which has a twin for hot swapping).
Codes which don't embedd any information about what you're saying or doing can be copied over to faked images.
In theory you could have such a pendant record your voice, etc, and continously emit signatures for compressed versions of your speech (or a signed speech-to-text transcript)
