“…The application of semantic web technologies to structured policy languages (eg XACML) has shown how its expressive power can easily accommodate such transformation and extensions but highlight several aspects for future research [30] and specific needs for a policy language for defining security requirements [31].…”

Abstract. The move towards the Policy-Oriented Web is destined to provide support for policy expression and management in the core web layers. One of the most promising areas that can drive this new technology adoption is eSociety communities. With so much user-generated content being shared by these social networks, there is the real danger that the implicit sharing rules that communities have developed over time will be lost in translation in the new digital communities. This will lead to a corresponding loss in confidence in eSociety sites. The Policy-Oriented Web attempts to turn the implicit into the explicit with a common framework for policy language interoperability and awareness. This paper reports on the policy driving factors from the Social Networks experiences using real-world use cases and scenarios. In particular, the key functions of policy-awareness -for privacy, rights, and identity -will be the driving force that enables the e-Society to appreciate new interoperable policy regimes.

Abstract. The protection of privacy in today's global infrastructure requires the combined application solution from technology (technical measures), legislation (law and public policy), and organizational and individual policies and practices. Emerging scenarios of user-service interactions in the digital world are also pushing toward the development of powerful and flexible privacy-enhanced models and languages.This paper aims at introducing concepts and features that should be investigated to fulfill this demand. In particular, the content of this paper is a result of our ongoing activity in the framework of the PRIME project (Privacy and Identity Management for Europe), funded by the European Commission, whose objective is the development of privacyaware solutions for enforcing security.

“…We propose using XACML which is a standard for representing access control rules. Although exportable policies can be deduced from these rules, it is not the principal goal, Damiani et al [17] also base their solution on XACML yet represent the rules in RDF. OWL-DL yields maximum expressiveness without loosing computational completeness.…”

“…Damiani et al [17] outline how "current standard poHcy languages such as XACML can be extended" to be able to semantically define access control policies for the Semantic Web. They propose the use of RDF to make the XACML policies more semantically aware.…”

In this paper we propose an authorisation definition and access control solution for Web Services. In our proposal we define our access control policies using an OWL-DL language based on the extensible Access Control Markup Language (XACML). We propose the use of resource and subject metadata ontologies, also written in OWL. We then present a complete Web Services architecture which incorporates this access control model. As part of this architecture we propose a novel document filtering mechanism according to the semantic enriched access control policies.
