Right, but that'll still leave some vectors open. Like how do I know my co-workers didn't just send all their deepfakebots to this meeting instead of actually attending? How do I know it's my children facetiming me in the nursing home and not just sending their bots to entertain me? There are some very morbid possibilities even if you require strong auth/signing/identity.

I don't agree. How is this not equivalent to the general authentication problem? If you consider your impression from the video stream to be the "password" then there must be a second factor to confirm it. Signed audio/video streams is probably where we're headed. Devices used for real time communication will just require a TPM (many already have them). > How do I know it's my children facetiming me in the nursing home and not just sending their bots to entertain me? That means that in order to call you their device will have to prove it's the actual stream from the actual camera module on their uniquely identified phone. Every component of a computer system will have cryptographic elements soon enough. There's no way around this if AI ever gets to that level.

  You’re probably right. That pretty much also means the end of general unregulated computer use. Will we allow it? It’s going to be a sad day.

  I have an idea to implement a badge that encodes the audio into a super low bandwidth stream with signing, then displays that stream as part of the video. It would tie a video stream to an audio stream to a signature. If the video is faked, the audio won't match, if the audio is faked, the signature won't match. The idea is anyone can attach the badge and be sure people know it's not deep faked.

The parties (coworkers, kids) you mentioned in the post are not meant to be your adversaries. If you’re in a position where you don’t trust them to not dupe you on a human level, you already lose. No technology in the world can help you
