Towards privacy-enhanced authorization policies and languages

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 privacy-aware solutions for enforcing security.
