I’ve wondered why this wasn’t an option in dash cams and otherwise.
I know I had security cams for a protected facility I use to work for – at first I was told what cameras to use, and then others were installed for me. But the first set that I actually had access to weren’t encrypted but signed. The output could be sent out and verified as unaltered – even with the fact that the storage would go from 240 frames per second down to one frame every few seconds when there was no movement (night time).
If you can sign it, cryptographically verifying it…why not encrypt it. It would seem to take similar amounts of power.
That said, even as a person who has little to hide, I really don’t want things like my dashcams along with audio (that I actually don’t record…but I could) – being taken and exposed to the world. I couldn’t imagine anything that actually was life and death.
