Ask HN: Could cryptographically verified testimony replace audio and video?

6 pointsJeff_Brown2 comments

Technologies like "deep fake" will soon throw audio and video evidence of someone's past actions in doubt. But public key cryptography remains unbroken. If enough people used PKC to sign their statements, could that not be a workable substitute?

Reference statements the solution is simply to write out the statement and sign it physically, keep the original, and provide copies.

I think technologies like deep fake may affect things like CCTV evidence, especially if it's veracity is thrown into doubt. I can see courts, where I live, having a hard time with this as currently CCTV evidence is treated as a truthful and objective account of people's actions beyond reproach.

There are problems here though. What if the key gets stolen or the bug found in the algorithm? All this makes it not very sustainable.
