Mention was made recently of a graphical keying method out of
stanford (?) for palm-pilots. Does anyone have a reference or url
for the paper/code involved?

The Design and Analysis of Graphical Passwords

Ian Jermyn, New York University; Alain Mayer, Fabian
Monrose, Michael K. Reiter, Bell Labs, Lucent
Technologies; and Aviel D. Rubin, ATT Labs--Research

Abstract

In this paper we propose and evaluate new graphical
password schemes that exploit features of graphical input
displays to achieve better security than text-based
passwords. Graphical input devices enable the user to
decouple the position of inputs from the temporal order in
which those inputs occur, and we show that this decoupling
can be used to generate password schemes with
substantially larger (memorable) password spaces. In order
to evaluate the security of one of our schemes, we devise
a novel way to capture a subset of the ``memorable''
passwords that, we believe, is itself a contribution. In
this work we are primarily motivated by devices such as
personal digital assistants (PDAs) that offer graphical
input capabilities via a stylus, and we describe our
prototype implementation of one of our password schemes on
such a PDA, namely the Palm PilotTM.
