Security is probably the most critical factor for the development of the "Information Society". E-government, e-commerce, e-healthcare and all other e-activities present challenging security requirements that cannot be satisfied with current technology, except maybe if the citizens accept to waive their privacy, which is unacceptable ethically and socially. New progress is needed in security and privacy-preserving technologies. On these foundations, the IFIP/SEC conference has been established from the eighties as one of the most important forums for presenting new scientific research results as well as best professional practice to improve the security of information systems. This balance between future technology improvements and day-to-day security management has contributed to better understanding between researchers, solution providers and practitioners, making this forum lively and fruitful. Security and Protection in Information Processing Systems contains the papers selected for presentation at the 19th IFIP International Conference on Information Security (SEC2004), which was held in August 2004 as a co-located conference of the 18th IFIP World Computer Congress in Toulouse, France. The conference was sponsored by the International Federation for Information Processing (IFIP).This volume is essential reading for scholars, researchers, and practitioners interested in keeping pace with the ever-growing field of information security.

The topics span the areas of haptic modeling, shared virtual worlds, virtual reality, human-computer interfaces, e-learning in virtual collaborative spaces, multi-user web games, cybersecurity, social networking, and art and heritage in cyberspaces.

Online Child Sexual Abuse: Grooming, Policing and Child Protection in a Multi-Media World addresses the complex, multi-faceted and, at times, counter-intuitive relationships between online grooming behaviours, risk assessment, police practices, and the actual danger of subsequent abuse in the physical world. Online child sexual abuse has become a high profile and important issue in public life. When children are victims, there is clearly intense public and political interest and concern. Sex offenders are society's most reviled deviants and the object of seemingly undifferentiated public fear and loathing. This may be evidenced in ongoing efforts to advance legislation, develop police tactics and to educate children and their carers to engage with multi-media and the internet safely. Understanding how sex offenders use the internet and how the police and the government are responding to their behaviour is central to the development of preventative measures. Based on extensive ethnographic research conducted with the police and a specialist paedophile unit, here Elena Marellozzo presents an informed analysis of online child sexual abuse: of the patterns and characteristics of online grooming, and of the challenges and techniques that characterize its policing. Connecting theory, research and practice in the field of policing, social policy, victimology and criminology, this book adds significantly to our understanding and knowledge of the problem of online child sexual abuse, the way in which victims are targeted and how this phenomenon is, and might be, policed.

The frequency of new editions of this book is indicative of the rapid and trem- dous changes in the fields of computer and information sciences. First published in 1995, the book has rapidly gone through three editions already and now we are in the fourth. Over this period, we have become more dependent on computer and telecommunication technology than ever before and computer technology has become ubiquitous. Since I started writing on social computing, I have been ad- cating a time when we, as individuals and as nations, will become totally dependent on computing technology. That time is almost on us. Evidence of this is embodied in the rapid convergence of telecommunication, broadcasting, and computing devices; the miniaturization of these devices; and the ever increasing storage capacity , speed of computation, and ease of use. These qualities have been a big pulling force sucking in millions of new users every day, sometimes even those unwilling. Other appealing features of these devices are the increasing number of applications, apps, as they are increasingly becoming known, and being wireless and easily portable. Whether small or big, these new gizmos have become the c- terpiece of an individual's social and economic activities and the main access point for all information. Individuals aside, computing technology has also become the engine that drives the nations' strategic and security infrastructures that control power grids, gas and oil storage facilities, transportation, and all forms of national communication, including emergency services.

Back in 1983 I was chatting with Dick Coleman, publisher of Traffic World magazine, when he unexpectedly proposed that I write a column for the magazine on computer applications in the transportation/physical distribution industry. "But, Dick, I don't know all that much about computers," I protested. "You use one, don't you?" he asked logically. Yes, I did; I'd been running my consulting business with it for two years. But that didn't, I explained, make me an expert. "Think about it," he said. That's typical Coleman; he drops these studiedly casual ideas and just lets them lay there until you pick them up and wind up doing just what he wanted you to do all along. Sure enough, the longer I pondered the notion the more it appealed to me. OK, I wasn't a computer expert (I'm still not). But I was a computer user, in the transportation/distribution field; maybe from that perspective I might have some useful things to say to other transportation/distribution users and would-be users of computers. Thus was born the "Computer Software for Transportation" column. The first one appeared in the April 11, 1983, issue of Traffic World, and it's been a once-a-month schedule ever since. And thus, too, was ultimately born this book.

The working group WG 11.4 of IFIP ran an iNetSec conference a few times in the past, sometimes together with IFIP security conference, sometimes as a stand-alone workshop with a program selected from peer-reviewed submissions. When we were elected to chair WG 11.4 we asked ourselveswhether the security and also the computer science community at large bene?ts from this workshop. In particular, as there aremany (too many?) securityconferences, it has become di?cult to keep up with the ?eld. After having talked to many colleagues, far too many to list all of them here, we decided to try a di?erent kind of workshop: one where people would attend to discuss open research topics in our ?eld, as typically only happens during the co?ee breaks of ordinary conferences. Toenablethiswecalledforabstractsof2pageswheretheauthorsoutlinethe open problems that they would like to discuss at the workshop, the intent being that the author would be given 15 minutes to present the topic and another 15 minutes for discussion. These abstracts were then read by all members of the Program Committee and ranked by them according to whether they thought thiswouldleadtoaninterestingtalk and discussion. We then simply selected the abstracts that got the best rankings. We were happy to see this result in many really interesting talks and disc- sions in the courseof the workshop.Ofcourse, these lively anddirect discussions are almost impossible to achieve in a printed text. Still, we asked the authors to distill the essence of these discussions into full papers. The results are in your hand

The First Conference on the History of Nordic Computing (HiNC1) was organized in Trondheim, in June 2003. The HiNC1 event focused on the early years of computing, that is the years from the 1940s through the 1960s, although it formally extended to year 1985. In the preface of the proceedings of HiNC1, Janis Bubenko, Jr. , John Impagliazzo, and Arne Solvberg describe well the peculiarities of early Nordic c- puting [1]. While developing hardware was a necessity for the first professionals, quite soon the computer became an industrial product. Computer scientists, among others, grew increasingly interested in programming and application software. P- gress in these areas from the 1960s to the 1980s was experienced as astonishing. The developments during these decades were taken as the focus of HiNC2. During those decades computers arrived to every branch of large and medium-sized businesses and the users of the computer systems were no longer only computer s- cialists but also people with other main duties. Compared to the early years of comp- ing before 1960, where the number of computer projects and applications was small, capturing a holistic view of the history between the 1960s and the 1980s is conside- bly more difficult. The HiNC2 conference attempted to help in this endeavor.

This book constitutes the thoroughly refereed proceedings of the First International Workshop on the Theory and Applications of Formal Argumentation, TAFA 2011, held in Barcelona, Spain, in Juli 2011, as a workshop at IJCAI 2011, the 22nd International Joint Conference on Artificial Intelligence. The 9 revised full papers presented together with 8 revised poster papers were carefully selected during two rounds of reviewing and improvement from 32 initial submissions. The workshop promotes and fosters uptake of argumentation as a viable AI paradigm with wide ranging application, and provides a forum for further development of ideas and the initiation of new and innovative collaborations. The papers cover the following topics: properties of formal models of argumentation; instantiations of abstract argumentation frameworks; relationships among different argumentation frameworks; practical applications of formal models of argumentation; argumentation and other artificial intelligence techniques; evaluation of formal models of argumentation; validation and evaluation of applications of argumentation.

Welcome to the 5th International Conference on Open Source Systems! It is quite an achievement to reach the five-year mark - that's the sign of a successful enterprise. This annual conference is now being recognized as the primary event for the open source research community, attracting not only high-quality papers, but also building a community around a technical program, a collection of workshops, and (starting this year) a Doctoral Consortium. Reaching this milestone reflects the efforts of many people, including the conference founders, as well as the organizers and participants in the previous conferences. My task has been easy, and has been greatly aided by the hard work of Kevin Crowston and Cornelia Boldyreff, the Program Committee, as well as the Organizing Team led by Bjoern Lundell. All of us are also grateful to our attendees, especially in the difficult economic climate of 2009. We hope the participants found the conference valuable both for its technical content and for its personal networking opportunities. To me, it is interesting to look back over the past five years, not just at this conference, but at the development and acceptance of open source software. Since 2004, the business and commercial side of open source has grown enormously. At that time, there were only a handful of open source businesses, led by RedHat and its Linux distribution. Companies such as MySQL and JBoss were still quite small.
