Yes. But maybe instead the physical sealing we could use a blockchain, which registers time and geotag of the recording?
A Blockchain cannot validate information received if the hardware is not secure, so it cannot replace the Fail-Deadly Key.
A Blockchain, on the other hand, could timestamp the hash as soon as it is generated to ensure it was created before a certain point in time.
May be use something like a projected outside crypto timestamp, by the photo flash?
