Based on two international workshops on trust in agent societies, held at AAMAS 2003 and AAMAS 2004, this book draws together carefully revised papers on trust, reputation, and security in agent society. Besides workshop papers, several contributions from leading researchers in this interdisciplinary field were solicited to complete coverage of all relevant topics.

The 13 papers presented take into account issues from multiagent systems, artificial intelligence, cognitive science, game theory, and social and organizational science. Theoretical topics are addressed as well as applications in human-computer interaction and e-commerce.

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.

This book is based on a workshop on Deception, Fraud, and Trust in Agent Societies held during the Autonomous Agents Conference in Barcelona, Spain in June 2000.Besides carefully reviewed revised full papers presented at the workshop the book presents invited papers from experts in the field allowing for complete coverage of the field.
