​NASDAQ inserts a digital time stamp from the National Institute of
Standards  into its financial transactions and then makes a
cryptographically secure hash out of it, that way anyone can prove when a
transaction occurred to within a fraction of a second. Perhaps not too far
from now it will be common practice for cameras, even cell phone cameras,
to do something similar. That way if somebody produces a video of me making
silly faces I can produce an older video without the clowning proving it
was altered.  I might also want to digitally sign any video of me. Of
course somebody could still make a phony video and claim it was made by a
hidden camera showing me doing something I shouldn't; the only way around
that I can think of is if I filmed myself 24/7 with digital time stamp
included, that way I'd always have an alibi.
