Today it is difficult to conveniently provide strong authentication
between devices that share no prior context, without the assistance
of a trusted authority. We present, analyze, and propose applications
for Seeing-Is-Believing, a system that utilizes machine vision on
camera-phones to achieve security properties formerly unattainable
in a non-intrusive way.
