Smart cities are a new vision for urban development. They integrate information and communication technology infrastructures – in the domains of artificial intelligence, distributed and cloud computing, and sensor networks – into a city, to facilitate quality of life for its citizens and sustainable growth. This book explores various concepts for the development of these new technologies (including agent-oriented programming, broadband infrastructures, wireless sensor networks, Internet-based networked applications, open data and open platforms), and how they can provide smart services and enablers in a range of public domains.The most significant research, both established and emerging, is brought together to enable academics and practitioners to investigate the possibilities of smart cities, and to generate the knowledge and solutions required to develop and maintain them.

For more than the last three decades, the security of software systems has been an important area of computer science, yet it is a rather recent general recognition that technologies for software security are highly needed.This book assesses the state of the art in software and systems security by presenting a carefully arranged selection of revised invited and reviewed papers. It covers basic aspects and recently developed topics such as security of pervasive computing, peer-to-peer systems and autonomous distributed agents, secure software circulation, compilers for fail-safe C language, construction of secure mail systems, type systems and multiset rewriting systems for security protocols, and privacy issues as well.

This book is a collection of papers presented at UCS 2004, held on November 8–9 in Tokyo. UCS is a series of international symposia sponsored by the special interest group Ubiquitous Computing Systems of the Information Processing Society of Japan. The ?rst UCS was held on November 17, 2003 in Kyoto. It was held as an invitation-based symposium. UCS 2004 was the second of the series, and the ?rst submission-based conference. UCS focuses on the emerging researcharea of ubiquitous computing systems. This emergence is an outcome of the rapid evolution in smart appliances and devices, as well as tremendous advances in wireless networks and mobile c- puting.Inthelastfewyears,variousapplicationsofinformationtechnologyhave been changing our everyday life rapidly and to a large extent. The best ex- ple is the use of mobile phones. By getting new sensing devices, cameras, their application ?eld is no longer limited to communication but covers data c- munications including Internet access, and data and program up-/downloading, and so on. The symposium o?ered the opportunity for in-depth exploration of the most recent research and development ?ndings in the ?eld of ubiquitous computing. The submitted papers presented at UCS 2004 suggest such a direction to future technologies, including mobile ad hoc networks, sensor networks and conte- aware technologies.

The 7th International Conference on Ubiquitous Computing (UbiComp 2005) marked the ?rst time that this premier venue for original research contributions in ubiquitous computing was held in Asia. The Tokyo, Japan venue re?ects the desireoftheUbiCompcommunitytomakethisconferenceseriesaninternational event that showcases the increasing amount of high-quality ubiquitous comp- ing researchthat is taking placeworldwide.As the ?eld ofubiquitous computing has matured, the UbiComp Conference has gained signi?cance worldwide, not only among researchers, but also with industry and general society. This interest in the potential of ubiquitous computing to impact our lives has resulted in the creation of many new research programs in academia and industry. These e?orts have, in turn, led to mass media coverage of e?orts and, in some regions of the world, large-scale government-initiated collaborative - forts to explore the potential of these emerging technologies. These trends are re?ected in the rise in the number of submissions to UbiComp 2005. This year the conference received 230 full papers, submitted almost equally from Asia (?100 submissions), North America and South America (?60 submissions) and Europe(?60submissions),withtheremainderbeingreceivedfromAustraliaand Africa. Fromamong many high-qualitysubmissions, the technical programc- mittee accepted 22 papers. These paperswere chosenbased solely on the quality of their peer reviews using a double-blind review process.

This book constitutes the refereed proceedings of the 7th International Conference on Pervasive Computing, Pervasive 2009, held in Nara, Japan, in May 2009. The 20 revised full papers and 7 revised short papers presented were carefully reviewed and selected from 147 initial submissions. The papers are organized in topical sections on digital displays, navigation, at home with pervasive applications, sensors, sensors, everywhere, working together, tagging and tracking, methods and tools, and the importance of context.
