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.
