Post by R***@dizum.comHi,
what is PGP Digital Timestamping: what is this good for? Who can
use it
and for what?
Anyone can use it.
I had an idea for a new software product and service that fell outside
of what the department where I worked did. I wanted to make sure
someone else did not claim credit for it.
I wrote up to product in a Word document, used PGP to obtain a detached
digital signature on the document, and sent the signature file to the
PGP Digital Timestamping Service. The Service returned its own detached
signature file on my signature file. Only after I received the
Service's signature file, I then sent the Word document to the proper
department where the software could be developed and the service marketed.
My signature file could be used to prove I had access to the Word
document. The PGP Digital Timestamping Service signature file could
then be used to prove I did not "diddle" my PC clock for the time-stamp
that appears in all PGP signatures; that is, I could establish my
priority of ownership of the Word document.
