Trust-based information sharing in collaborative communities: Issues and challenges

Abstract

Collaborative communities are today one of the emerging trends in the ICT area. This is mainly due to the widespread adoption of Web 2.0 related technologies, having, as one of their major goal, that of facilitating user collaboration and knowledge sharing. Clearly, the wide adoption of collaborative tools would take place only if users have assurance that their privacy and security requirements are preserved when sharing information. In this paper, we focus on access control and the related privacy issues. We start by revising the state of the art in the field, then we discuss which are the main requirements for a privacy-aware access control mechanism for collaborative communities. Then, we briefly describe some of the results we have achieved in this field. © 2009 Vieweg+Teubner Verlag | GWV Fachverlage GmbH, Wiesbaden.
