Sounds like a very Biden thing (or for anyone well into their Golden Years) to say, "Use cryptography!" but it's not without merit. How do we verify file integrity? How to we digitally sign documents?
The problem we currently have is that anything that looks real tends to be accepted as real (or authentic). We can't rely on humans to verify authenticity of audio or video anymore. So for anything that really matters we need to digitally sign it so it can be verified by a certificate authority or hashed to verify integrity.
This doesn't magically fix deep fakes. Not everyone will verify a video before distribution and you can't verify a video that's been edited for time or reformatted or broadcast on the TV. It's a start.
We've had this discussion a lot in the Bitcoin space. People keep arguing it has to change so that "grandma can understand it" but I think that's unrealistic. Every technology has some inherent complexities that cannot be removed and people have to learn if they want to use it. And people will use it if the motivation is there. Wifi has some inherent complexities people have become comfortable with. People know how to look through lists of networks, find the right one, enter the passkey or go through the sign on page. Some non-technical people know enough about how Wifi should behave to know the internet connection might be out or the route might need a reboot. None of this knowledge was commonplace 20 years ago. It is now.
The knowledge required to leverage the benefits of cryptographic signatures isn't beyond the reach of most people. The general rules are pretty simple. The industry just has to decide to make the necessary investments to motivate people.
The President's job isn't really to be an expert on everything, the job is more about being able to hire people who are experts.
If this was coupled with a regulation requiring social media companies to do the verification and indicate that the content is verified then most people wouldn't need to do the work to verify content (because we know they won't).
It obviously wouldn't solve every problem with deepfakes, but at least it couldn't be content claiming to be from CNN or whoever. And yes someone editing content from trusted sources would make that content no longer trusted, but that's actually a good thing. You can edit videos to make someone look bad, you can slow it down to make a person look drunk, etc. This kind of content should not considered trusted either.
Someone doing a reaction video going over news content or whatever could have their stuff be considered trusted, but it would be indicated as being content from the person that produced the reaction video not as content coming from the original news source. So if you see a "news" video that has it's verified source as "xXX_FlatEarthIsReal420_69_XXx" rather than CNN, AP News, NY Times, etc, you kinda know what's up.
The number of 80 year olds that know what cryptography is AND know that it's a proper solution here is not large. I'd expect an 80 year old to say something like "we should only look at pictures sent by certified mail" or "You cant trust film unless it's an 8mm and the can was sealed shut!"
