Tell HN: I had an idea to mitigate the risk of being framed with a fake video
One starting point would be to wear a device that takes pictures 24/7, geotags them and uploads a signature to a blockchain. Then, if and when a video surfaces of you doing some unspeakable act, you can issue the following challenge:
- When and where do you say this was?
Then the attacker would have to guess a plausible time and place. It must be one in which there is no other footage of you to contradict the account. Let's say they say: this happened on July 4th at 3pm, inside a room at the Grand Hotel. They know you where there because they saw you check in. If you were wearing this device, you could produce a trail of pictures spaced one minute apart, geotagged and verifiable. Of course it's not perfect, but it's a start.
It's pretty clear that videos and pictures are no longer proof of anything, so I believe these types of preventive steps will be a matter of necessity in the near future (at least for public figures).
