Comment on An AI startup made a hyperrealistic deepfake of me that’s so good it’s scary

Why should I trust the authenticity of your signning key? Solution 1: web of trust like PGP. Impossible with foreign content. Solution 2: Trusted Certificate authorities (private/ state/ UN) Solution 3: a block chain (scaling problems)

If I generate a key pair and use it to sign a file and distribute it and then I publish the public key somewhere like Facebook, any recipient of the file could be assured that the file originated from my Facebook account. A public certificate is not required to do this. As to whether the Facebook account holder is actually me is another problem, but hopefully major social media platforms require at least a photo ID.
