I have hitherto not timestamped or cryptographically signed my light sources, but that's something I'll be looking into.

Wonder if you could measure your breathing rate and heartbeat and cryptographically sign the time series data as ground truth. Then post process the video with Eulerian Video Magnification to recover the values and compare.

Might be interesting if you are a high-value individual. Maybe in the future we will see a secret service member shining a light on the POTUS at all times to ensure that no fake video of the President can be circulated. Maybe with a scheme where they publish the keys used after each day, to build trust and make sure anyone can verify the authenticity of any video containing the President

Or anyone else who cares enough about deepfakes and can afford the effort

I’m not sure I understand. Could someone not take an existing legitimate video, light and all, then manipulate it to e.g. have the president saying something else?
