Foreword by Lars Knudsen Practical Intranet Security focuses on the various ways in which an intranet can be violated and gives a thorough review of the technologies that can be used by an organization to secure its intranet. This includes, for example, the new security architecture SESAME, which builds on the Kerberos authentication system, adding to it both public-key technology and a role-based access control service. Other technologies are also included such as a description of how to program with the GSS-API, and modern security technologies such as PGP, S/MIME, SSH, SSL IPSEC and CDSA. The book concludes with a comparison of the technologies. This book is different from other network security books in that its aim is to identify how to secure an organization's intranet. Previously books have concentrated on the Internet, often neglecting issues relating to securing intranets. However the potential risk to business and the ease by which intranets can be violated is often far greater than via the Internet. The aim is that network administrators and managers can get the information that they require to make informed choices on strategy and solutions for securing their own intranets. The book is an invaluable reference for network managers and network administrators whose responsibility it is to ensure the security of an organization's intranet. The book also contains background reading on networking, network security and cryptography which makes it an excellent research reference and undergraduate/postgraduate text book.

The NSF Center for Intelligent Information Retrieval (CIIR) was formed in the Computer Science Department of the University of Massachusetts, Amherst, in 1992. Through its efforts in basic research, applied research, and technology transfer, the CIIR has become known internationally as one of the leading research groups in the area of information retrieval. The CIIR focuses on research that results in more effective and efficient access and discovery in large, heterogeneous, distributed text and multimedia databases. The scope of the work that is done in the CIIR is broad and goes significantly beyond 'traditional' areas of information retrieval such as retrieval models, cross-lingual search, and automatic query expansion. The research includes both low-level systems issues such as the design of protocols and architectures for distributed search, as well as more human-centered topics such as user interface design, visualization and data mining with text, and multimedia retrieval.Advances in Information Retrieval: Recent Research from the Center for Intelligent Information Retrieval is a collection of papers that covers a wide variety of topics in the general area of information retrieval. Together, they represent a snapshot of the state of the art in information retrieval at the turn of the century and at the end of a decade that has seen the advent of the World-Wide Web. The papers provide overviews and in-depth analysis of theory and experimental results. This book can be used as source material for graduate courses in information retrieval, and as a reference for researchers and practitioners in industry.

The volume contains the papers presented at the fifth working conference on Communications and Multimedia Security (CMS 2001), held on May 21-22, 2001 at (and organized by) the GMD -German National Research Center for Information Technology GMD - Integrated Publication and Information Systems Institute IPSI, in Darmstadt, Germany. The conference is arranged jointly by the Technical Committees 11 and 6 of the International Federation of Information Processing (IFIP) The name "Communications and Multimedia Security" was first used in 1995, Reinhard Posch organized the first in this series of conferences in Graz, Austria, following up on the previously national (Austrian) "IT Sicherheit" conferences held in Klagenfurt (1993) and Vienna (1994). In 1996, the CMS took place in Essen, Germany; in 1997 the conference moved to Athens, Greece. The CMS 1999 was held in Leuven, Belgium. This conference provides a forum for presentations and discussions on issues which combine innovative research work with a highly promising application potential in the area of security for communication and multimedia security. State-of-the-art issues as well as practical experiences and new trends in the areas were topics of interest again, as it has already been the case at previous conferences. This year, the organizers wanted to focus the attention on watermarking and copyright protection for e commerce applications and multimedia data. We also encompass excellent work on recent advances in cryptography and their applications. In recent years, digital media data have enormously gained in importance.

The short history of the International Working Conference on Educating Professionals for Network Centric Organizations is a good illustration of the tremendous rate of development of global networking, its impact and of its deep penetration into management of business, industty and administration. In 1996, when the theme and name of the conference had been set, there was yet no heavy use of networks in the fields just mentioned. However, it has been already established well enough to enable those with a visionary sense to feel that it will be an important subject and it could be an interesting theme for a conference to be held within two years. It seemed a risky decision at the time but it turned out to be very successful when conducted in 1998. It has been stated that "it took until 1997 for the business world to discover the Internet". In less than two years, the Internet and the Intranets are a vital component for running major parts of the business world. This fast pace puts some pressure on writing papers and holding a conferenc- effort has to be made to have meaningful contents despite the changes. A time span of 9 months between writing a paper and having it published, seemed once to be very short, but it is not so any more when referring to a dynamic issue like global networking.

Color Theory and Modeling for Computer Graphics, Visualization, and Multimedia Applications deals with color vision and visual computing.

Color Theory and Modeling for Computer Graphics, Visualization, and Multimedia Applications is suitable as a secondary text for a graduate-level course on computer graphics, computer imaging, or multimedia computing and as a reference for researchers and practitioners developing computer graphics and multimedia applications.

This volume is the Proceedings of the First International Workshop on Entertainment Computing (IWEC 2002). Entertainment has been taking very important parts in our life by refreshing us and activating our creativity. Recently by the advancement of computers and networks new types of entertainment have been emerging such as video games, entertainment robots, and network games. As these new games have a strong power to change our lives, it is good time for people who work in this area to discuss various aspects of entertainment and to promote entertainment related researches. Based on these considerations, we have organized a first workshop on entertainment computing. This workshop brings together researchers, developers, and practitioners working in the area of entertainment computing. It covers wide range of entertainment computing such as theoretical issues, hardware/software issues, systems, human interfaces, and applications. The particular areas covered by the workshop are: 1. Computers & Games Computer game algorithms, modeling of players, web technologies for networked games, human interface technologies for game applications. 2. Home/Arcade Games and Interactive Movies Video game computer technologies, motion capture technologies, real-time computer graphics technologies, interactive movie systems, story generation for games/movies, human factors of video games.

The growth of the Internet and the availability of enormous volumes of data in digital form has necessitated intense interest in techniques for assisting the user in locating data of interest. The Internet has over 350 million pages of data and is expected to reach over one billion pages by the year 2000. Buried on the Internet are both valuable nuggets for answering questions as well as large quantities of information the average person does not care about. The Digital Library effort is also progressing, with the goal of migrating from the traditional book environment to a digital library environment. Information Retrieval Systems: Theory and Implementation provides a theoretical and practical explanation of the latest advancements in information retrieval and their application to existing systems. It takes a system approach, discussing all aspects of an Information Retrieval System. The importance of the Internet and its associated hypertext-linked structure is put into perspective as a new type of information retrieval data structure.The total system approach also includes discussion of the human interface and the importance of information visualization for identification of relevant information. The theoretical metrics used to describe information systems are expanded to discuss their practical application in the uncontrolled environment of real world systems. Information Retrieval Systems: Theory and Implementation is suitable as a textbook for a graduate-level course on information retrieval, and as a reference for researchers and practitioners in industry.

Dictation systems, read-aloud software for the blind, speech control of machinery, geographical information systems with speech input and output, and educational software with 'talking head' artificial tutorial agents are already on the market. The field is expanding rapidly, and new methods and applications emerge almost daily. But good sources of systematic information have not kept pace with the body of information needed for development and evaluation of these systems. Much of this information is widely scattered through speech and acoustic engineering, linguistics, phonetics, and experimental psychology. The Handbook of Multimodal and Spoken Dialogue Systems presents current and developing best practice in resource creation for speech input/output software and hardware. This volume brings experts in these fields together to give detailed 'how to' information and recommendations on planning spoken dialogue systems, designing and evaluating audiovisual and multimodal systems, and evaluating consumer off-the-shelf products.In addition to standard terminology in the field, the following topics are covered in depth: * How to collect high quality data for designing, training, and evaluating multimodal and speech dialogue systems; * How to evaluate real-life computer systems with speech input and output; * How to describe and model human-computer dialogue precisely and in depth. Also included: * The first systematic medium-scale compendium of terminology with definitions. This handbook has been especially designed for the needs of development engineers, decision-makers, researchers, and advanced level students in the fields of speech technology, multimodal interfaces, multimedia, computational linguistics, and phonetics.

The home is a key aspect of society and the widespread use of computers and other information appliances is transforming the way in which we live, work and communicate in the information age. The importance of this subject has never been greater with the encroachment of information technology into every corner of the home and social spheres. Many more homes in the developed world will have access to information and information technology in the near future, forming an information society. This book seeks to answer the questions surrounding this move to a 'wired society', such as: * How is the new technology actually used? * What are the effects on society as a whole? * How will it affect human relationships? * Who will gain and who will lose? * What technology is there to support everyday life? * What services do people really want? * How do we study aspects of this phenomenon? GBP/LISTGBP Home Informatics and Telematics brings together papers from researchers around the world who are looking at this challenging problem domain.There are contributions on the technical computing areas associated with the home, the HCI of household technology, and theoretical studies on the sociological, psychological and methodological aspects of information technology in everyday life.

INTRODUCTION TO COMPUTER-AIDED DESIGN OF USER INTERFACES l 2 Jean Vanderdonckt and Angel Puerta ,3 Jlnstitut d'Administration et de Gestion - Universite catholique de Louvain Place des Doyens, 1 - B-1348 Louvain-la-Neuve (Belgium) vanderdonckt@gant,ucl. ac,be , vanderdoncktj@acm,org Web: http://www. arpuerta. com JKnowledge Systems Laboratory, Stanford University, MSOB x215 Stanford, CA 94305-5479, USA puena@camis. stanford. edu 3RedWhaie Corp. , 277 Town & Country Village Palo Alto, CA 94303, USA puerta@ redwhale. com Web: http://www. redwhale. com Computer-Aided Design of Vser Interfaces (CADUI) is hereby referred to as the particular area of Human-Computer Interaction (HCI) intended to provide software support for any activity involved in the development life cycle of an interactive application, Such activities namely include task analysis, contextual inquiry [l], requirements definition, user-centred design, application modelling, conceptual design, prototyping, programming, in- stallation, test, evaluation, maintenance, Although very recently addressed (e. g. , [3]), the activity of re-designing an existing user interface (VI) for an interactive application and the activity of re-engineering a VI to rebuild its underlying models are also considered in CADVI. A fundamental aim of CADVI is not only to provide some software sup- port to the above activities, but also to incorporate strong and solid meth- odological aspects into the development, thus fostering abstraction reflection and leaving ad hoc development aside [5,7]. Incorporating such methodo- logical aspects inevitably covers three related, sometimes intertwined, facets: models, method and tools.

Animation, Embodiment and Digital Media articulates the human experience of technology-mediated animated phenomena in terms of sensory perception, bodily action and imaginative interpretation, suggesting a new theoretical framework with analyses of exemplary user interfaces, video games and interactive artworks.

Packed with numerous examples this easy-to-use manual provides designers of interactive media with a practical guide to screen design. Written for the working designer the manual shows how to rework information so that it is suitable for the chosen target group and the media they are using. It describes background information and encourages further development of the language of digital media. In doing so it covers all aspects of screen design, including: perception and learning, ergonomics, communication theory, image research, aesthetics, and the design of navigation and orientation elements.

ConieD is the biannual Congress on Computers in Education, organised by the Spanish Association for the Development of Computers in Education (ADIE). The last Congress, held in Puertollano (Ciudad Real), brought together researchers in different areas, ranging from web applications, educational environments, or Human-Computer Interaction to Artificial Intelligence in Education. The common leitmotiv of the major part of the lectures was the World Wide Web. In particular, the focus was on the real possibilities that this media presents in order to make the access of students to educational resources possible anywhere and anytime. This fact was highlighted in the Conclusions of the Congress following this Preface as the Introduction. From the full 92 papers presented to the Programme Committee we have selected the best 24 papers that we are presenting in this book. The selection of papers was a very difficult process, taking into account that the papers presented in the Congress (60) were all good enough to appear in this book. Only the restrictions of the extension of this book have limited the number of papers to 24. These papers represent the current high-quality contributions of Spanish research groups in Computers in Education. Manuel Ortega Cantero Jose Bravo Rodriguez Editors xiii Introduction ConieD 99 (1st National Congress on Computers in Education) has brought together a very important group of Spanish and Latin American researchers devoted to studying the application and use of computers in education."

Mastering interoperability in a computing environment consisting of different operating systems and hardware architectures is a key requirement which faces system engineers building distributed information systems. Distributed applications are a necessity in most central application sectors of the contemporary computerized society, for instance, in office automation, banking, manufacturing, telecommunication and transportation. This book focuses on the techniques available or under development, with the goal of easing the burden of constructing reliable and maintainable interoperable information systems. The topics covered in this book include: * Management of distributed systems; * Frameworks and construction tools; * Open architectures and interoperability techniques; * Experience with platforms like CORBA and RMI; * Language interoperability (e.g. Java); * Agents and mobility; * Quality of service and fault tolerance; * Workflow and object modelling issues; and * Electronic commerce .The book contains the proceedings of the International Working Conference on Distributed Applications and Interoperable Systems II (DAIS'99), which was held June 28-July 1, 1999 in Helsinki, Finland.

Cellular Automata Transforms describes a new approach to using the dynamical system, popularly known as cellular automata (CA), as a tool for conducting transforms on data. Cellular automata have generated a great deal of interest since the early 1960s when John Conway created the `Game of Life'. This book takes a more serious look at CA by describing methods by which information building blocks, called basis functions (or bases), can be generated from the evolving states. These information blocks can then be used to construct any data. A typical dynamical system such as CA tend to involve an infinite possibilities of rules that define the inherent elements, neighborhood size, shape, number of states, and modes of association, etc. To be able to build these building blocks an elegant method had to be developed to address a large subset of these rules. A new formula, which allows for the definition a large subset of possible rules, is described in the book. The robustness of this formula allows searching of the CA rule space in order to develop applications for multimedia compression, data encryption and process modeling. Cellular Automata Transforms is divided into two parts. In Part I the fundamentals of cellular automata, including the history and traditional applications are outlined. The challenges faced in using CA to solve practical problems are described. The basic theory behind Cellular Automata Transforms (CAT) is developed in this part of the book. Techniques by which the evolving states of a cellular automaton can be converted into information building blocks are taught. The methods (including fast convolutions) by which forward and inverse transforms of any data can be achieved are also presented. Part II contains a description of applications of CAT. Chapter 4 describes digital image compression, audio compression and synthetic audio generation, three approaches for compressing video data. Chapter 5 contains both symmetric and public-key implementation of CAT encryption. Possible methods of attack are also outlined. Chapter 6 looks at process modeling by solving differential and integral equations. Examples are drawn from physics and fluid dynamics.

It is certain that, over the next few years, data traffic will dwarf voice traffic on telecommunications networks. Growth in data-traffic volumes far exceeds that for voice, and is driven by increased use of applications such as e-mail attachments, remote printing and fileserver access, and the now omnipresent World Wide Web. The growth of data networking to connect computers with each other and with their peripheral devices began in earnest in the 1970s, took off in the 1980s and exploded in the 1990s. The early 21st century will see ever faster, more cost effective networks providing flexible data access into ever more businesses and homes. Since the 1970s there have been great advances in technology. For the past twenty years the processing power of computers has continued to grow with no hint of slowing - recall the oft-cited Moore's Law claiming that this power doubles every 18 months. Advances in the data networking equipment required to support the data traffic generated have been enormous. The pace of development from early X. 25 and modem technology through to some of the advanced equipment functionality now available is breathtaking - it is sometimes hard to believe that the practical router is barely ten years old! This book provides an overview of the advanced data networking field by bringing together chapters on local area networks, wide area networks and their application.
