The vision of ubiquitous computing and ambient intelligence describes a world of technology which is present anywhere, anytime in the form of smart, sensible devices that communicate with each other and provide personalized services. However, associated with these benefits are concerns with respect to security issues. Open interconnected systems are much more vulnerable to attacks and unauthorized data access. Furthermore, it becomes simpler to collect, store, and search personal information and endanger people's privacy.

In the context of this menace, Petkovic and Jonker provide a comprehensive guide to data management technologies with respect to security, privacy and trust. After the introductory part that offers a perspective on privacy and security issues in the modern digital world, the contributions from leading researchers are grouped into sections on data and system security, privacy-enhancing techniques, digital asset protection, and selected topics on privacy and security in ambient intelligence. Overall, the book delivers, from information on the ethical and legislative background, to chapters on the state-of-the-art technologies such as access control, identity management and digital rights management to advice on implementing fair information practices and preventing security and privacy violations. With this broad approach, this book appeals equally to researchers and graduate students looking for an overview of this area of ever-growing importance and to professional developers who require sound theoretical grounds for the design and implementation of secure privacy-preserving ubiquitous applications.

Zusammenfassung
Advances in information and communication technologies continue to p- vide new means of conducting remote transactions. Services facilitated by these technologies are spreading increasingly into our commercial and private spheres. For many people, these services have changed the way they work, communicate, shop, arrange travel, etc. Remote transactions, however, may also open possibilities for fraud and other types of misuse. Hence, the requi- ment to authorize transactions may arise. Authorization may in turn call for some kind of user authentication. When users have to provide personal inf- mation to access services, they literally leave a part of their life on record. As the number of sites where such records are left increases, so does the d- ger of misuse. So-called identity theft has become a pervasive problem, and a general feeling of unease and lack of trust may dissuade people from using the services on o?er. This,inanutshell,isoneofthemajorchallengesinsecurityengineering- day. How to provide servicesto individuals securelywithout making undue - cursions into their privacy at the same time. Decisions on the limits of privacy intrusions or privacy protection, for that matter are ultimately political decisions. Research can de?ne the design space in which service providers and regulators may try to ?nd acceptable tradeo?s between security and privacy.
