It is becoming quite clear that there will be important technological advances in - bile and wireless connectivity, known as third-/fourth-generation (3G and 4G) mobile telecommunications systems. As a result we will be surrounded by ever-growing m- tidomain (technical and administrative) heterogeneous communications in both wired and wireless networks. This resulting environment deals with communication in m- tizoned networks, where people, devices, appliances and servers are connected to each other via different kinds of networks. Networks will be pervasive, ubiquitous, multis- vice, multioperatorand multiaccess. The mobility trend will also be spurred forward by the growing availability of mobile-enabled handheld devices. Mobile systems are expected to provide mobile users with cost-effective, secure, yet ubiquitous service access anywhere and anytime. Users will then continue to enjoy the new-found freedom mobile access provides and will have increasingly high exp- tations of mobility-aware applications that should be capable of seamlessly supporting the mobile lifestyle. The papers in this volume discuss issues from models, platforms, and architectures for mobility-aware systems to security, mobile agent technologies, sensitive com- nications, context awareness, mobile applications and management. They cover both practical experience and novel research ideas and concepts.

This book constitutes the thoroughly refereed post-proceedings of the International Workshop on Deception, Fraud, and Trust in Agent Societies, held in Bologna, Italy in July 2002 during AAMAS 2002. Most papers presented were carefully selected from the workshop contributions during two rounds of reviewing and revision; a few papers were particularly solicited in order to provide complete coverage of all relevant topics. All relevant aspects of the field are addressed.

The tremendous growth of the Internet is successfully making a variety of e-services a part of citizens' everyday life. E-services such as: Web-banking, Web shopping, e-learning, e-healthcare, and e-government, are available in most countries around the world. Trust in E-Services: Technologies, Practices and Challenges provides an overview of e-service trust issues, including: definitions, constructs, and relationships with other research topics such as security, privacy, reputation, and risk. Trust in E-Services: Technologies, Practices and Challenges introduces and discusses the existing trust platforms and management tools such as trust evaluation, reasoning approaches, and mechanisms for e-services. This book also offers contributions from researchers and practitioners with real-life experience and practice on how to build a trust environment for e-government services.
