How will we actually verify a video is real in the near future? I’ve been thinking about this a lot lately, for many of the same reasons. I think one answer can be found in device-level signing of images and A/V feeds. A recorder can integrate its cryptographic signing and keystore on the same chip as its CCD/audio controllers, like Apple’s T2 chip does, so that it has the ability to sign direct feeds from the hardware as being such. This might be more complicated for A/V than still images, since a large enough recording would have to be written to disk. Perhaps some rolling scheme could be devised. For an added measure of verification, the SoC could upload them (optionally encrypted) to a distributed public store like a blockchain or IPFS, proving that they were created at/around a certain time. This seems like it would be useful in concert with other tools for news agencies (who should be leading the way in providing as much documented research and evidence for things as they can, as a matter of course, while protecting their sources), law enforcement (who is losing the public’s trust when it comes to the chain of custody and testimony), etc. We jumped very far ahead both in how much importance we place on digital documents and in how easily we can forge them, so we need to catch up fast on finding robust mechanisms for verification.
