] Like most information technologies, Mobile and Ubiquitous
] Computing carries a number of security and privacy
] implications. We feel that care should be taken to
] consider these issues when designing Ubicomp systems. In
] this report we will enumerate a number of the privacy
] concerns in Ubicomp and provide a philisophical
] discussion of the importance of addressing these
] problems. In considering these problems we have found
] that a number of Ubicomp techniques are in fact well
] suited to solving security and privacy problems that
] arise in Ubicomp. We will discuss some of these
] techniques in the hope of inspiring further
] consideration. Systems described include a secure RF-ID
] system, an architecture for setting privacy levels based
] on context, and a wearable cryptographic authenticator.

This is probably the coolest paper I've ever written, and for one of the coolest classes I ever took. I'm linking this here because I've had to dig it out of Georgia Tech's site twice now and I figure it ought to be easy to find...
