Sustaining Privacy in Autonomous Collaborative Environments

(SPACE 2007)

July 30, 2007

to be held at IFIPTM 2007

July 30 th – August 2 nd, 2007

Welcome to the First International Workshop on Sustaining Privacy in Autonomous Collaborative Environments (SPACE2007) pages. The objectives and technical issues of the workshop are as follows:

The objectives and technical issues of the workshop are as follows:

  1. Identification of the essential weaknesses and risks of autonomous distributed applications with respect to users' privacy including legal aspects specifically in the new emergent field of electronic collaborative environments. This workshop will identify the main problems, the primary factors, and the principal actors with respect to various contexts and business cases. It will also focus on new security and privacy concerns that arise in autonomous environments, such as Virtual Organizations, and in connection with emerging collaborative environments that may integrate large scale infrastructures, Web Services, Grid Computing, etc.

  2. Identification of the limitations and restrictions imposed by security and privacy, including legal and corporate compliance in highly distributed open systems and in autonomous collaborative environments.

  3. Identification of both malicious and accidental attempts to exploit information exchange and storage that is subject to privacy restrictions.

  4. Solutions and technical approaches for privacy protection (demonstrations of functionalities and implementation trade-offs with respect to security, privacy level, performance, cost, etc.).

  5. Examination and review of privacy compliance with respect to laws and corporate requirements as well as proposed solutions for the collaborative environments context.

  6. Clarifying how security protocols could be included within existing specifications, such as the new IEEE Foundations for Intelligent Physical Agents (FIPA) specifications or Privacy Preferences Project (P3P) specifications.

The workshop will also encourage multi-disciplinary papers from attendees as well as a holistic discussion of issues related to the key objectives outlined above.


Call for Papers

SPACE 2007 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. Under these circumstances, privacy becomes a fundamental issue, because entities interact on behalf of their owners and these owners should have confidence concerning:

  • who holds their private information,

  • who can access it 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 (E-Commerce, Grid Computing, Pervasive Computing, Semantic Web, etc.), there are 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 will 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 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 other communities, such as law and business that present these communities’ perspectives on technological issues.

We call for two types of paper submission:

  • Long papers for innovative technical contributions in any of the workshop topic areas: limited to 10 pages in the Springer-Verlag LNCS Proceedings Author Guidelines (see Authors of long papers will be given 20 minutes presentation.

  • Short papers describing implementation experiences, requirements or giving position statements relevant to the workshop topics: limited to 4 pages. Authors of short papers will be given 5 minutes presentation to introduce their work.
