To allow for an efficient usage of a device in pervasive computing environments, reliable and yet convenient user access is an important requirement. The problem becomes more complex when the accessed device is shared by the public with many different individuals. This paper first illustrates the common pitfalls and issues of establishing sessions to such devices. The paper then proposes a context-aware solution that uses different contexts to capture a usage session. The paper presents a general system design that supports a secure, selective, and identifiable user access of public shared devices with high usability. We have implemented a prototype system to demonstrate the concept. Keywords Body Sensor Networks, Pervasive Computing, User Access
