Activity Zones for Context-Aware Computing distances to various landmarks. A user’s concept of location, however, is often defined in terms of regions in which similar activities occur. We discuss the concept of such regions, which we call activity zones, and suggest that such zones can be used to trigger application actions, retrieve infor

Context-Aware User Authentication – Supporting Proximity-Based Login in Pervasive Computing for UbiComp systems. We present a context-aware user authentication protocol, which (1) uses a JavaCard for identification and cryptographic calculations, (2) uses a context-awareness system for verifying the user’s location, and (3) implements a security fall-back strategy. We analyze the security

Secure Spontaneous Device Association in ad hoc circumstances. Spontaneity typically arises when nomadic users carry one or more of the devices around. We contribute a method of using lasers for securing spontaneous device associations. The method provides users with physical evidence of which device they have connected their device to

AwareCon: Situation Aware Context Communicationration. With the AwareCon network, we address these challenges by prescribing an integrated architecture that differs from classical networking, as it features an awareness of the surrounding situation and context. In various settings, where AwareCon was implemented on tiny battery driven devices, w

liquid: Context-Aware Distributed Queriesata. Information required by a context-aware application may be partitioned by any number of physical, organizational, or privacy boundaries. This suggests the need for mechanisms by which applications can issue context-sensitive queries without having to explicitly manage the complex storage layout

Is Context-Aware Computing Taking Control away from the User? Three Levels of Interactivity Examinedly an application should perform. After defining three levels of interactivity between a mobile computing device and its user: personalization, passive context-awareness and active context-awareness, we test which approach will limit users’ perceived sense of control. We also investigate users’ pref
