Meta’s Creepy Skin Deep “Security” Idea

Let’s see Mark Zuckerberg’s skin vibrations 🐍
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.
Or, alternatively, just showing up to do stuff in person. Of course that's not always feasible but still.
Honestly, I don't find this very creepy. This is information you are already putting out there for everyone to see. If I post a video of myself speaking, I am not concerned about people seeing how my skin vibrates in that video.
As video generation tools become more advanced, we will need better algorithms to validate videos. The bar for "fooling the vast majority of humans" is much, much lower than the bar for "being literally indistinguishable from a real video". The main problem I see is that it's going to be a cat-and-mouse game, and I don't think any method you publish will remain valid for very long in practice. The same method will be used to improve the next version of video generators.
Also, lots of real videos use post-processing that might wash out some of the details they are looking for. Video producers might re-record lines so they don't perfectly match the video to begin with. It's been a long time since I used a Samsung phone, but on my old S6, I remember that it always had a beauty filter applied to the selfie camera that made me me look like a creepy porcelain doll. I could probably make a deepfake of myself that looks more "real" than those real videos and photos.
So we'll have deepfaked skin vibrations?
