This book provides an understanding of the core pillars of trust and reputation systems in electronic business settings. It presents the main existing methods and evaluates them from a managerial point of view. The book outlines the necessary technological environment without entangling the reader in too much technical detail. An implementation roadmap on a strategic and tactical level is given as well as guidance on linking trust and reputation management to existing information systems. Existing standards and solutions like recommendation systems, web services, semantic and big data technologies are put into context to prevent subverting efforts using false ratings, faked identities and other security issues. An outlook into recent and future developments completes the book.

The increasing relevance of security to real-life applications, such as electronic commerce, is attested by the fast-growing number of research groups, events, conferences, and summer schools that are studying it. This book presents thoroughly revised versions of eight tutorial lectures given by leading researchers during two International Schools on Foundations of Security Analysis and Design, FOSAD 2006/2007, held in Bertinoro, Italy, in September 2006 and September 2007.

Gossip and reputation are core processes in societies and have substantial consequences for individuals, groups, communities, organizations, and markets.. Academic studies have found that gossip and reputation have the power to enforce social norms, facilitate cooperation, and act as a means of social control. The key mechanism for the creation, maintenance, and destruction of reputations in everyday life is gossip - evaluative talk about absent third parties. Reputation and gossip are inseparably intertwined, but up until now have been mostly studied in isolation. The Oxford Handbook of Gossip and Reputation fills this intellectual gap, providing an integrated understanding of the foundations of gossip and reputation, as well as outlining a potential framework for future research. Volume editors Francesca Giardini and Rafael Wittek bring together a diverse group of researchers to analyze gossip and reputation from different disciplines, social domains, and levels of analysis. Being the first integrated and comprehensive collection of studies on both phenomena, each of the 25 chapters explores the current research on the antecedents, processes, and outcomes of the gossip-reputation link in contexts as diverse as online markets, non-industrial societies, organizations, social networks, or schools. International in scope, the volume is organized into seven sections devoted to the exploration of a different facet of gossip and reputation. Contributions from eminent experts on gossip and reputation not only help us better understand the complex interplay between two delicate social mechanisms, but also sketch the contours of a long term research agenda by pointing to new problems and newly emerging cross-disciplinary solutions.

This book constitutes the refereed proceedings of the 6th IFIP WG 11.11 International Conference, IFIPTM 2012, held in Surat, India, in May 2012. The 12 revised full papers presented together with 8 short papers and the abstracts of 4 keynote talks were carefully reviewed and selected from 51 submissions. Building on the traditions inherited from the iTrust and previous IFIPTM conferences, IFIPTM 2012 is a multi-disciplinary conference focusing on areas such as: trust models, social, economic and behavioural aspects of trust, trust in networks, mobile systems and cloud computation, privacy, reputation systems, and identity management.

Security and privacy protection within computer networks can be a challenge. By examining the current problems and challenges this domain is facing, more efficient strategies can be established to safeguard personal information against invasive pressures. Security and Privacy in Smart Sensor Networks is a critical scholarly resource that examines recent developments and emerging trends in smart sensor security and privacy by providing new models, practical solutions, and technological advances related to security. Featuring coverage on a broad range of topics such as cloud security, encryption, and intrusion detection systems, this book is geared towards academicians, engineers, IT specialists, researchers, and students seeking current research on authentication and intrusion detection.

Reputation is the sum of individual perceptions, experiences and beliefs in the mind of a company's stakeholder. Therefore, synchronous stakeholder communication and interaction has to respect the needs of all parties involved. Reputation management is the total of concepts, processes and structures that are directed towards the effective management of reputation within a company. It covers all activities to establish, preserve, improve and defend reputation systematically. Private banking is a highly sensitive and trust requiring business. A strong bank brand and a healthy reputation are its key success factors. Private banks concentrate on prosperous clientele; therefore, they know that the loss of the good name is one of the major business risks. Although the significant role of reputation in private banking is commonly clear, a systematic management of corporate reputation is rarely. This book investigates the current status of reputation management in private banking and identifies reputation drivers. Consequently, a survey on German private banks is being conducted. Based upon the findings, a structure for corporate reputation management under aspects of good corporate governance will be derived. Regarding corporate reputation management as a consulting product, opportunities for the consulting industry are presented in conclusion.

This book constitutes the refereed proceedings of two workshops held in conjunction with the 8th FIRA International Conference on Secure and Trust Computing, Data Management, and Applications, STA 2011, in Crete, Greece, in June 2011. STA 2011 is the first conference after the merger of the successful SSDU, UbiSec, and TRUST symposium series previously held from 2006 until 2010 in various locations. The 14 full papers of the IWCS 2011 and 10 papers of the STAVE 2011 workshop were carefully reviewed and individually selected from the lectures given at each workshop. The International Workshop on Convergence Security in Pervasive Environments, IWCS 2011, addresses the various theories and practical applications of convergence security in pervasive environments. The International Workshop on Security & Trust for Applications in Virtualized Environments, STAVE 2011, shows how current virtualization increases the sharing of compute, network and I/O resources with multiple users and applications in order to drive higher utilization rates, what replaces the traditional physical isolation boundaries with virtual ones.

In distributed, open systems like cyberspace, where the behavior of autonomous agents is uncertain and can affect other agents' welfare, trust management is used to allow agents to determine what to expect about the behavior of other agents. The role of trust management is to maximize trust between the parties and thereby provide a basis for cooper
