“…Among the several non-logical approaches that have been proposed for the problems of privacy preservation and data access control, we distinguish trust management systems, such as PolicyMaker [124], KeyNote [125], REFEREE [126] and SPKI/SDSI [127], which focus on aspects of trust, such as access control and authorization; and the Personal Data Stream (PDS) framework proposed in [128]. PDS is designed to give users new data management tools, based on three foundational design principles: privacy of participants, data legibility, and engagement of participants throughout the data life cycle.…”

Abstract. Today, privacy is a key concept. It is also one which is rapidly evolving with technological advances, and there is no consensus on a single definition for it. In fact, the concept of privacy has been defined in many different ways, ranging from the "right to be left alone" to being a "commodity" that can be bought and sold. In the same time, powerful Ambient Intelligence (AmI) systems are being developed, that deploy context-aware, personalised, adaptive and anticipatory services. In such systems personal data is vastly collected, stored, and distributed, making privacy preservation a critical issue. The humancentred focus of AmI systems has prompted the introduction of new kinds of technologies, e.g. Privacy Enhancing Technologies (PET), and methodologies, e.g. Privacy by Design (PbD), whereby privacy concerns are included in the design of the system. One particular application field, where privacy preservation is of critical importance is Ambient Assisted Living (AAL). Emerging from the continuous increase of the ageing population, AAL focuses on intelligent systems of assistance for a better, healthier and safer life in their living environment. In this paper, we first build on our previous work, in which we introduced a new tripartite categorisation of privacy as a right, an enabler, and a commodity. Second, we highlight the specific privacy issues raised in AAL. Third, we review and discuss current approaches for privacy preservation. Finally, drawing on lessons learned from AAL, we provide insights on the challenges and opportunities that lie ahead. Part of our methodology is a statistical analysis performed on the IEEE publications database. We illustrate our work with AAL scenarios elaborated in cooperation with the city of Luxembourg.

“…The policy and credential language with which we will conduct our work will be based on KeyNote, 6 with extensions we will add to support dynamic policies. In particular, we will introduce new constructs to the language that support an active trigger mechanism for policies and tested conditions.…”

“…6 Our starting point is the PolicyMaker 1,2 evaluation model; our concept of cross-layer communication stems from thesis work on the Strongman system. 9 We are investigating integration of intrusion detection and other security-event generators with access-control mechanisms and other appropriate response and recovery mechanisms, such as slowdowns in response to attack.…”

Citizen identification systems (known also as 'ID card systems', or 'national identity management systems', even though those definitions are not identical) are receiving a mixed acceptance, with their privacy, security and usability being criticised, specifically in the UK. This paper investigates whether it is possible to improve social acceptance of such systems in cases where they are incompatible with the perceived value of privacy, but without significantly changing their original architecture. The paper analyses requirements using four different scenarios that address long-term privacy issues. Relatively small alterations to such systems are suggested that may significantly improve their adoption.
