Trust Theory: A Socio-Cognitive and Computational Model
Tutorial at Autonomous Agents & Multi-Agent Systems Conference (AAMAS 2010)
May 11 2010, Toronto, Canada

Organizers
Rino Falcone

Description
In this tutorial we will define and analyze the socio-cognitive approach to trust also comparing it with the different other approaches developed in the last 10 years in the Agents and Multi-Agent Systems domain. In fact the relevance of the research on trust in this domain is strongly influenced by the increasing quality and variety of the autonomy concept realizations in artficial agents (particularly supported by evolved programming languages and development tools for multi-agent systems implementation).
In this context of increasing autonomy for the agents, trust becames a foundamental mediator of the social action. And social action is the essential nucleous of the new societies (in which human-artificial, artificial-artificial, and human-human-through-artificial interactions are all increaasing presents).
A particular emphasis will be placed on the notion of trust, with its related concepts of Lack of Trust, Implicit Trust, Mistrust. Without a clear conceptualization of this concept any attempt of rationalize and model it would be useless or deviant. At the same time we will also analyze the quantitative aspects of trust, its dynamics, the relationships with control, and autonomy.

13th International Workshop on Trust in Agent Societies (TRUST10)

To be held at Autonomous Agents & Multi-Agent Systems Conference (AAMAS 2010)
May 10, 2010, Toronto, Canada

Organizers
Rino Falcone, Suzanne Barber, Jordi Sabater and Munindar Singh.

Description
The aim of the workshop is to bring together researchers who can contribute to a better understanding of trust and reputation in agent societies. Most agent models assume secure and reliable communication to exist between agents. However, this ideal situation is seldom met in reality. In fact, many techniques (e.g. contracts, signatures, long-term personnel relationships, reputation) have been evolved over time to detect and prevent deception and fraud in human communication, exchanges and relations, and hence to assure trust between agents. Artificial societies will need analogous techniques.

5th ACM SAC TRECK Track
Trust, Reputation, Evidence and other Collaboration Know-how (TRECK 2009)

ACM Symposium on Applied Computing 2009 Trust, Reputation, Evidence and other Collaboration Know-how (TRECK) Track
March 8 - 12, 2009. Waikiki Beach, Honolulu, Hawaii, USA.

Track Program Chair:
Jean-Marc Seigneur

Description
Computational models of trust and online reputation mechanisms have been gaining momentum. The ACM SAC 2005, 2006, 2007 and 2008 TRECK tracks attracted researchers from both academia and industry who have joined an online group at http://tech.groups.yahoo.com/group/trustcomp/
The goal of the ACM SAC 2009 TRECK track remains to review the set of applications that benefit from the use of computational trust and online reputation. Computational trust has been used in reputation systems, risk management, collaborative filtering, social/business networking services, dynamic coalitions, virtual organisations and even combined with trusted computing hardware modules. The TRECK track covers all computational trust/reputation applications, especially those used in real-world applications.

Fourth International Workshop on the Value of Security through Collaboration (SECOVAL 2008)

part of SECURECOMM'08 in cooperation with ACM and CREATE-NET
September 22, Istanbul, Turkey

Workshop Co-chairs:
Jean-Marc Seigneur and Adam Slagell

Description
Security is usually centrally managed, for example in a form of policies duly executed by individual nodes. The SECOVAL workshop covers the alternative trend of using collaboration and trust to provide security. Instead of centrally managed security policies, nodes may use specific knowledge (both local and acquired from other nodes) to make security-related decisions. For example, in reputation-based schemes, the reputation of a given node (and hence its security access rights) can be determined based on the recommendations of peer nodes. As systems are being deployed on ever-greater scale without direct connection to their distant home base, the need for self management is rapidly increasing. Interaction after interaction, as the nodes collaborate, there is the emergence of a digital ecosystem. By guiding the local decisions of the nodes, for example, with whom the nodes collaborate, global properties of the ecosystem where the nodes operate may be guaranteed. Thus, the security property of the ecosystem may be driven by self-organizing mechanisms. Depending on which local collaboration is preferred, a more trustworthy ecosystem may emerge. This year SECOVAL is focusing upon a special research subtopic mobile collaborative security

IFIP Sec 2007

New Approaches for Security, Privacy & Trust in Complex Environments
14 - 16 May 2007
Sandton Convention Centre, Sandton, South Africa

Description
Information is now the most important commodity in a global market. Individuals, businesses and governments are dependable on information embedded in secure, privacy aware and trustworthy IT infrastructures. Classical information security services such as authentication and authorisation urgently demand a re-design and improved implementation to ensure security, privacy and trust features in today’s integrated and complex information rich environments.
