Digital signatures provide a mechanism for guaranteeing integrity and authenticity of Web content but not more general notions of security or trust. Web-aware applications must permit users to state clearly their own security policies and, of course, must provide the cryptographic tools for manipulating digital signatures. This paper describes the REFEREE trust management system for Web applica...

The paper provides a selective analysis of the main theories of trust and e-trust (that is, trust in digital environments) provided in the last twenty years, with the goal of preparing the ground for a new philosophical approach to solve the problems facing them. It is divided into two parts. The first part is functional toward the analysis of e-trust: it focuses on trust and its definition and...

While the literature on trust has produced various conceptual models, there is also some confusion concerning different types of trust and their formation. In this article, three contested points are empirically clarified. First, are there really different forms of trust as much of the literature suggests? Second, if so, then how are these different types of trust related to each other? Third, ...

Artificial societies distributed systems of autonomous agents are becoming increasingly important in open distributed environments, especially in e-commerce. Agents require trust and reputation concepts in order to identify communities of agents with which to interact reliably. We have noted in real environments that adversaries tend to focus on exploitation of the trust and reputation model. T...

Trust has been viewed as an integral component of agent decision making in the context of multiagent systems (MASs). Various formal and semi-formal trust schemes, motivated by diverse considerations and influenced by various fields of study, have been proposed, implemented, and evaluated. We believe that there still exists a pressing need for developing a comprehensive trust management scheme t...

Peer-to-peer networks have become increasingly popular in the recent years. In an open peer-to-peer network peers often have to interact with unknown peers and need to manage the risk in their communications. It is very important for peers to select a trustworthy peer to accomplish a task. Peers must be able to determine the trustworthiness of other peers to increasing uncertainty and risk. Thu...

Trust and reputation systems provide a foundation for security, stability, and efficiency in the online environment because of their ability to stimulate quality and to sanction poor quality. Trust and reputation scores are assumed to represent and predict future quality and behaviour and thereby to provide valuable decision support for relying parties. This assumption depends on two factors, p...

Trust and Control at the Workplace: Evidence from Representative Samples of Employees in Europe Based on two representative samples of employees, the German Socio Economic Panel and the European Social Survey, we explore the relation between certain measures of control in employment relationships (i.e. working time regulations, use of performance appraisal systems, monitoring by supervisors, au...

CHAPTER 2 – LITERATURE REVIEW 2.1 Background Lack of trust has always been identified as one of the most formidable barriers to people engaging in e-commerce use. This involves transactions in which both financial and personal information is submitted to unknown merchants by the Internet. Trust was often cited as the main reason why many customers are still sceptical about some online vendors (...
