While e-commerce has experienced meteoric growth recently, security risks have similarly grown in scope and magnitude. Three major factors have driven the security risks in e-commerce: the growing reliance on the electronic medium for a company's core business, the growing complexity of the software systems needed to support e-commerce, and the value of the digital assets brought online to an inherently insecure medium - the Internet. While security has long been a primary concern in e-commerce, more recently privacy has also grown in importance to consumers. Many of the same Internet technologies that make e-commerce possible also make it possible to create detailed profiles of an individual's purchases, to spy on individual Web usage habits, and even to peer into confidential files that reside on an individual's machine. E-Commerce Security and Privacy is the first volume to pull together leading researchers and practitioners in diverse areas of computer science and software engineering to explore their technical innovations to problems in security and privacy in e-commerce. The information is drawn from selected papers presented at the first Workshop on Security and Privacy in E-Commerce (WSPEC'00) held in Athens, Greece, November 4, 2000. As such, E-Commerce Security and Privacy introduces both practitioners and researchers to innovations in secure and private e-commerce. Practitioners will gain great insight from the case studies, and researchers will learn about state-of-the-art protocols in secure and private e-commerce that will serve as the basis for future innovations in applied e-commerce technologies. E-Commerce Security and Privacy is suitable as a secondary text for agraduate level course, and as a reference for researchers and practitioners in industry.

'Securing Web Services' investigates the security-related specifications that encompass message level security, transactions, and identity management.

DSSSL (Document Style Semantics and Specification Language) is an ISO standard (ISO/IEC 10179: 1996) published in the year 1996. DSSSL is a standard of the SGML family (Standard Generalized Markup Language, ISO 8879:1986), whose aim is to establish a processing model for SGML documents. For a good understanding of the SGML standard, many books exist including Author's guide[BryanI988] and The SGML handbook[GoldfarbI990]. A DSSSL document is an SGML document, written with the same rules that guide any SGML document. The structure of a DSSSL document is explained in Chapter 2. DSSSL is based, in part, on scheme, a standard functional programming language. The DSSSL subset of scheme along with the procedures supported by DSSSL are explained in Chapter 3. The DSSSL standard starts with the supposition of a pre-existing SGML document, and offers a series of processes that can be performed on it: * Groves The first process that is performed on an SGML document in DSSSL is always the analysis of the document and the creation of a grove. The DSSSL standard shares many common characteristics with another standard of the SGML family, HyTime (ISO/IEC 10744). These standards were developed in parallel, and their developers designed a common data model, the grove, that would support the processing needs of each standard.

This visionary book presents an interdisciplinary and cogent approach to the issue of Internet governance and control. By examining five critical areas in which the tension between freedom and control is most palpable--fair competition and open access, free expression, intellectual property, privacy rights, and security--Spinello guides the reader on a tour of the emerging body of law and public policy that has attempted to control the anarchy of cyberspace. In so doing, he defends the credo of Internet self-regulation, asserting that the same powerful and flexible architectures that created the Internet as we know it today can be relied upon to aid the private sector in arriving at a workable, decentralized regulatory regime. Except in certain circumstances that require government involvement, self-regulation is not only viable but is a highly preferred alternative to the forced uniformity that centralized structures tend to impose.

Beginning with an exploration of the Internet's most important values, including universality, free expression, and open access, as well as its promise as a democratizing force, Spinello considers how we can most effectively preserve those values and fulfill that promise while curtailing the social harms that vex Internet users. How do we arrive at the right mixture of technology and policy so that the Internet does not lose its promise as a liberating technology? In examining this question, Spinello evaluates such architectures of control as filters and rights management protocols, which attempt to keep out unwanted information and protect intellectual property, respectively. He explores how these and other technologies can be designed and used responsibly so that online social order can be sustained with a minimal amount of government intervention.

The Social Web (including services such as MySpace, Flickr, last.fm, and WordPress) has captured the attention of millions of users as well as billions of dollars in investment and acquisition. Social websites, evolving around the connections between people and their objects of interest, are encountering boundaries in the areas of information integration, dissemination, reuse, portability, searchability, automation and demanding tasks like querying. The Semantic Web is an ideal platform for interlinking and performing operations on diverse person- and object-related data available from the Social Web, and has produced a variety of approaches to overcome the boundaries being experienced in Social Web application areas.

After a short overview of both the Social Web and the Semantic Web, Breslin et al. describe some popular social media and social networking applications, list their strengths and limitations, and describe some applications of Semantic Web technology to address their current shortcomings by enhancing them with semantics. Across these social websites, they demonstrate a twofold approach for interconnecting the islands that are social websites with semantic technologies, and for powering semantic applications with rich community-created content. They conclude with observations on how the application of Semantic Web technologies to the Social Web is leading towards the "Social Semantic Web" (sometimes also called "Web 3.0"), forming a network of interlinked and semantically-rich content and knowledge.

The book is intended for computer science professionals, researchers, and graduates interested in understanding the technologies and research issues involved in applying Semantic Web technologies to social software. Practitioners and developers interested in applications such as blogs, social networks or wikis will also learn about methods for increasing the levels of automation in these forms of Web communication.

The Semantic Web aims at machine agents that thrive on explicitly specified semantics of content in order to search, filter, condense, or negotiate knowledge for their human users. A core technology for making the Semantic Web happen, but also to leverage application areas like Knowledge Management and E-Business, is the field of Semantic Annotation, which turns human-understandable content into a machine understandable form. This book reports on the broad range of technologies that are used to achieve this translation and nourish 3rd millennium applications. The book starts with a survey of the oldest semantic annotations, viz. indexing of publications in libraries. It continues with several techniques for the explicit construction of semantic annotations, including approaches for collaboration and Semantic Web metadata. One of the major means for improving the semantic annotation task is information extraction and much can be learned from the semantic tagging of linguistic corpora. In particular, information extraction is gaining prominence for automating the formerly purely manual annotation task - at least to some extent.An important subclass of information extraction tasks is the goal-oriented extraction of content from HTML and / or XML resources.

Private online digital currency systems offer people accessible, convenient, and inexpensive everyday financial tools outside of traditional bank-owned and operated platforms. Digital currency systems facilitate local and international fund transfers, online and offline payments, and simple cash-to-digital everyday financial products without the need for a conventional bank account of any retail bank product. Over the past several years, Bitcoin has grown into an efficient person-to-person and person-to-business payment system without the backing of any bank or financial institution. This phenomenon is producing a new level of an on- and offline commerce and a society much more attuned to digital currency systems. The Digital Currency Challenge details how new 2007-2008 U.S. legal issues surrounding digital currency products forced companies from the U.S. market and caused the Treasury Department to enact stricter regulations. Mullan profiles new and innovative present day digital currency systems, such as Bitcoin, and illustrates how software designers and monetary theorists use new technology to circumvent current U.S. regulations. This work also explains how new digital currency systems are not just software products, but tools providing financial freedom to people in countries all around the world.

The Web is growing at an astounding pace surpassing the 8 billion page mark. However, most pages are still designed for human consumption and cannot be processed by machines. This book provides a well-paced introduction to the Semantic Web. It covers a wide range of topics, from new trends (ontologies, rules) to existing technologies (Web Services and software agents) to more formal aspects (logic and inference). It includes: real-world (and complete) examples of the application of Semantic Web concepts; how the technology presented and discussed throughout the book can be extended to other application areas.

This book examines two main topics, namely, Wireless Networking and Mobile Data Management. It is designed around a course the author began teaching to senior undergraduate and master's students at the Department of Computer Science & Engineering of the Indian Institute of Technology Kanpur. The first part of the book, consisting of eight chapters, including the introduction, focuses exclusively on wireless networking aspects. It begins with cellular communication systems, which provided the foundation of wireless networking principles. Three subsequent chapters are devoted to the Global System for Mobile communication (GSM), Wireless Local Area Network (WLAN), Bluetooth, infrared (IR), ZigBee and 6LoWPAN protocols. There is also a chapter on routings in ad hoc networks, an area that is currently being intensively researched due to its potential applications in areas of vehicular network, traffic management, tactical and military systems. Furthermore, the book discusses mobile operating systems and wireless network application level protocols such as Wireless Application Protocols (WAP), Mobile IP and Mosh. The second part highlights mobile data management. It addresses the issues like location management, the importance of replication and caching in mobile environments, the concept of broadcast disk and indexing in air, storage systems for sharing data in mobile environments, and building smart environments. Given that the design of algorithms is the key to applications in data management; this part begins with a chapter on the type of paradigm shift that has been introduced in the design of algorithms, especially due to asymmetry in mobile environments. Lastly, the closing chapter of the book explores smart environments, showing the readers how wireless technology and mobile data management can be combined to provide optimum comfort for human life. Though the book has been structured as a monograph, it can be used both as a textbook and as a reference material for researchers and developers working in the area.

Electronic commerce is here to stay. No matter how big the dot-com crisis was or how far the e-entrepreneurs' shares fell in the market, the fact remains that there is still confidence in electronic trading. At least it would appear that investors are confident in e-companies again. However, not only trust of venture capitalists is of importance--consumers also have to have faith in on-line business. After all, without consumers there is no e-business. Interacting lawyers, technicians and economists are needed to create a trustworthy electronic commerce environment. To achieve this environment, thorough and inter-disciplinary research is required and that is exactly what this book is about. Researchers of the project Enabling Electronic Commerce from the Dutch universities of Tilburg and Eindhoven have chosen a number of e-topics to elaborate on trust from their point of view. This volume makes clear that the various disciplines can and will play a role in developing conditions for trust and thus contribute to a successful electronic market.

The pervasiveness of the Internet has had a significant impact on global politics, economics, and culture. To create a truly effective product in such a saturated digital environment, developers must study what has come before and how they can utilize existing tools to even greater effect. Evaluating Websites and Web Services: Interdisciplinary Perspectives on User Satisfaction explores some of the various approaches to the study and assessment of Internet technologies, providing scholars, researchers, developers, and professionals with critical knowledge and an interdisciplinary perspective on e-services in a variety of functional areas, from government and commerce to social media and education.

This book focuses on the modeling and management of spatial data in distributed systems. The authors have structured the contributions from internationally renowned researchers into four parts. The book offers researchers an excellent overview of the state-of-the-art in modeling and management of spatial data in distributed environments, while it may also be the basis of specialized courses on Web-based geographical information systems.

The Workshop on the Economics of Information Security was established in 2002 to bring together computer scientists and economists to understand and improve the poor state of information security practice. WEIS was borne out of a realization that security often fails for non-technical reasons. Rather, the incentives of both - fender and attacker must be considered. Earlier workshops have answered questions ranging from?nding optimal levels of security investement to understanding why privacy has been eroded. In the process, WEIS has attracted participation from the diverse?elds such as law, management and psychology. WEIS has now established itself as the leading forum for interdisciplinary scholarship on information security. The eigth installment of the conference returned to the United Kingdom, hosted byUniversityCollegeLondononJune24-25,2009.Approximately100researchers, practitioners and government of?cials from across the globe convened in London to hear presentations from authors of 21 peer-reviewed papers, in addition to a panel and keynote lectures from Hal Varian (Google), Bruce Schneier (BT Co- terpane), Martin Sadler (HP Labs), and Robert Coles (Merrill Lynch). Angela Sasse and David Pym chaired the conference, while Christos Ioannidis and Tyler Moore chaired the program committee.

The importance of knowledge and information technology management has been emphasized both by researchers and practitioners in order for companies to compete in the global market. Now such technologies have become crucial in a sense that there is a need to understand the business and operations strategies, as well as how the development of IT would contribute to knowledge management and therefore increase competitiveness. Knowledge and Information Technology Management: Human and Social Perspectives strives to explore the human resource and social dimensions of knowledge and IT management, to discuss the opportunities and major issues related to the management of people along the supply chain in Internet marketing, and to provide an understanding of how the human resource and the IT management should complement each other for improved communication and competitiveness.

A successful cyber-physical system, a complex interweaving of hardware and software with some part of the physical environment, depends on proper identification of the, often pre-existing, physical element. A bespoke "cyber" part of the system may then be designed from scratch. Optimal Mobile Sensing and Actuation Strategies in Cyber-physical Systems focuses on distributed-parameter systems the dynamics of which can be modelled with partial differential equations. These are very challenging to observe, their states and inputs being distributed throughout a spatial domain. Consequently, systematic approaches to the optimization of sensor location have to be devised for parameter estimation. The text begins by reviewing the field of cyber-physical systems and introducing background notions of distributed parameter systems and optimal observation theory. New research problems are then defined within this framework. Two important problems considered are optimal mobile sensor trajectory planning and the accuracy effects and allocation of remote sensors. These are followed up with a solution to the problem of optimal robust estimation. Actuation policies are then introduced into the framework with the purpose of improving estimation and optimizing the trajectories of both sensors and actuators simultaneously. The large number of illustrations within the text will assist the reader to visualize the application of the methods proposed. A group of similar examples are used throughout the book to help the reader assimilate the material more easily. The monograph concentrates on the use of methods for which a cyber-physical-systems infrastructure is required. The methods are computationally heavy and require mobile sensors and actuators with communications abilities. Application examples cover fields from environmental science to national security so that readers are encouraged to link the ideas of cyber-physical systems with their own research.
