Something I've wondered lately is what will life be like in a post-truth society? we already see examples of this now where a large number of people get their news from fake memes on facebook. There are huge swathes of people who live in their own make-believe world, like those believing wholeheartedly that the 2020 election was stolen. What will life be like when you can't trust any video or interview you see becaus…
For instance, a camera sensor could be designed such that every image that is captured on the sensor gets signed by the sensor at the hardware level, with a certificate that is embedded by the manufacturer. Then any video released could be verified against a certificate provided by the manufacturer. Of course, you have to trust the manufacturer, but that’s an easier pill to swallow (and better supported by our legal framework) than having to try and authenticate each video you watch independently.
There are issues that can arise (what if I put a screen in front of a real camera??, what if the CIA compromises the supply chain???), but at the end of the day it makes attacks much more challenging than just running some deepfake software. So there are things that can be done, we’re not destined for a post truth world where we can’t trust any media we see.
