Meta plans to scan for “skin vibrations” to combat deepfakes
Meta’s Creepy Skin Deep “Security” Idea

This has been around for a while in research papers. Getting people’s pulse rate, and even blood pressure from videos.
Other things you can get from videos, electrical interference to determine which power grid somebody is using. Noises in the background can be mapped as well. So uploading a video deanonymizes you quite well, for properly motivated investigator.
In the escalating war against deepfakes however it will just be part of the arms race, and new deepfakes will now include those fluctuations.
The only other way to combat deep fakes is something that people and companies constantly fuck up: cryptography.
Yeah, it really shouldn’t be hard to digitally sign a video along with a number of the frames. We’ve had the tech for decades.
We’re starting to see it in some cameras, mostly for still photography, but I don’t see why the basic concept wouldn’t extend to video files, too. Leica released a camera last year that signs the photo, including the timestamp and location data, and Canon, Nikon, Sony, Adobe, and Getty have various implementations of the technique.
Once the major photo software editing workflows support it, we’ll probably see some kind of chain of custody authentication support from camera to publication.
Of course, that doesn’t prevent fakes in the sense of staged productions, but the timestamp and location data would go a long way.
