SPACE 2008

Sustaining Privacy in Autonomous Collaborative Environments

(June 17, 2008)

held by
The Joint iTrust and PST Conferences on Privacy, Trust Management and Security
18-20 June 2008, Trondheim, Norway





Welcome to the Second Workshop on Sustaining Privacy in Autonomous Colllaborative Environments (SPACE 2008)

This workshop aims to provide a forum to discuss privacy and legal issues as well as to describe research results regarding privacy technology in distributed collaborative environments. Collaboration is conducted on the basis of interactions and information exchange between autonomous entities. When autonomous entities are deployed in open environments, privacy becomes a fundamental issue, because entities interact on behalf of their owners or representatives. Since information exchange in the form of interactions between autonomous entities are handled on behalf of the owners, these owners should know:
- who holds their private information,
- who can access it, for what duration, and for which purpose and,
- how this information is handled (in order to avoid unauthorized changes or unauthorized transfers).
With heterogeneous technologies (autonomous and multi-agent systems, mobile systems, web services, etc.) playing an increasingly important role in new distributed computing activities (Ambient Intelligence, E-Commerce, Grid Computing, Pervasive Computing, Semantic Web, etc.), there are increasing risks that the privacy and integrity of users’ information will not be maintained.
In light of these developments, a thorough analysis of threats to privacy and their causes must be reviewed. Issues with respect to the degree of privacy loss, the release of constraints in terms of protection, and how they might be assessed will be addressed. The workshop will also examine and compare new and different approaches, along with their technical solutions and practical designs, in open distributed environments. In addition, the workshop will attempt to examine the degree to which legal and organizational compliance for privacy in autonomous collaborative environments can or should be achieved.
The workshop invites submissions from academia and industry presenting novel research on all theoretical and practical aspects of privacy issues related to autonomous collaborative environments. We encourage submissions from communities such as law, the social sciences, and business that present these communities’ perspectives on technological issues.
