There are also another "world", which need cryptography in cameras.
Police itself, because current digital images are often defeated in
cases by lawyers, because lack of source verification. Any digital
records are taken like suspicious, can be easily modified and nobody can
verify the truth.
Current industry solution are use the metadata in picture format (i.e.
EXIF). But for proper evidence, there are needs to got positioning,
timestamp and camera ID, signed together in tamperproof hardware and/or
use independent certification authority for timestamping of electronic
But there are no such things available.
