W3C Workshop on
Languages for Privacy Policy Negotiation and Semantics-Driven Enforcement

17 and 18 October 2006 -- Ispra/Italy
hosted by the Joint Research Center (JRC) of the European Commission

Workshop Goals and Scope


This Workshop tries to bring together the IT-industry with a need for the management of personal data like e-health, customer relation management, new online community services etc on the one hand and privacy researchers from all over the world on the other hand. See the following section on scope for more specific information.


The automatic processing and exchange of personal information is a central part of today's IT landscape, in both government and business contexts. To allow enterprises to control data effectively according to regulations, agreements or privacy policies, design of privacy technologies has to extend beyond user-facing front-ends. Tools have to allow control of the whole privacy value-chain.

The technologies used for privacy control need to be integrated with diverse systems and environments. These environments range from legacy systems to advanced emerging technologies such as service-oriented architectures, web services, and novel web applications and cross-business processes.

This workshop is expected to explore a number of technologies that will help to address privacy needs in this context:

Similar privacy issues also arise in novel Web applications: When web services are combined in "mash-ups", personal information is processed by several service providers; users need to understand how the privacy policies of these providers interact, and users' privacy preferences need to be enforced.

The workshop is expected to consider the applicability of and lessons learned from existing and emerging technologies in privacy and user-centric identity management, including XACML, P3P, APPEL, and emerging solutions and approaches from the vendor and research communities. The workshop is also expected to consider the applicability of Semantic Web technologies to privacy enforcement use cases.

Workshop Goals

The aim of this workshop is to bring together vendors, researchers, users, and the broader privacy community to identify specific areas for further work on languages for privacy policies and enforcement, and to make recommendations to W3C about possible next steps toward developing specifications in these areas.
