One of the hardest problems we face in the IT security space is that of user authentication. In other words, are you really who you claim to be? One the one hand, it’s something we do every day when we run into people we know (or don’t know), yet there have continue to be cases of impersonation, which means our systems for verifying authenticity aren’t perfect. Complicating matters is when this identity verification happens at opposite ends of a wire in cyberspace where many of the mechanisms we rely on in the physical world elude us.
