Overview
The use of contextual information in ubiquitous computing raise evident trust issues (e.g., privacy protection, context quality) but also open new possibilities (e.g., location-based services, geo-encryption). The special session aims to stimulate an exchange ofideas on the topic of context and trust management in ubiquitous computing; it offers scientists and engineers that are active in the area to discuss the state of the art, to identify open and emerging problems, to share research experiences, and to propose future research directions.
