In the paper we address the trustworthiness of computational engineering distributed systems based on semantic web services. We present a security model with three components: web service messaging, monitoring and replication. Web service messaging has well standardized scenarios that we use as a foundation of our work oriented to trust monitoring and replication control. The model incorporate ...

Metadata produced by members of a diverse community of peers tend to contain low-quality or even mutually inconsistent assertions. Trust values computed on the basis of users’ feedback can improve metadata quality and reduce inconsistency, eliminating untrustworthy assertions. In this paper, we describe an approach to metadata creation and improvement, where community members express their opin...

The strategic use of private information causes efficiency losses in traditional principal-agent settings. One stream of research states that these efficiency losses cannot be overcome if all agents use their private information strategically. Yet, another stream of research highlights the importance of communication, trust and trustworthiness in supply chain management. The underlying work lin...

A traditional approach to reasoning about the trustworthiness of a transaction is to determine the trustworthiness of the specific agent involved, based on its past behavior. As a departure from such traditional trust models, we propose a transaction centered trust model (MetaTrust) where an agent uses its previous transactions to assess the trustworthiness of a potential transaction based on a...

How trustworthy is your voice? The effects of voice manipulation on the perceived trustworthiness of novel speakers How trustworthy is your voice? The effects of voice manipulation on the perceived trustworthiness of novel speakers ABSTRACT A person's voice is not only loaded with cues to age, sex and emotional state, listeners also readily form personality impressions of novel speakers. Based ...

Adaptation to facial characteristics, such as gender and viewpoint, has been shown to both bias our perception of faces and improve facial discrimination. In this study, we examined whether adapting to two levels of face trustworthiness improved sensitivity around the adapted level. Facial trustworthiness was manipulated by morphing between trustworthy and untrustworthy prototypes, each generat...

People often form expectations about others using the lens of their own attitudes (the so-called consensus effect). We study the implications of this for trust and trustworthiness. Trustworthy individuals are more “optimistic” than opportunists and are accordingly less afraid to engage in market-based exchanges, where they may be vulnerable to opportunistic behavior. In some cases, the material...

Information systems exist in every aspect of our life. Therefore we need to make sure that users trust these systems in order to continue to use them. However, developing a trustworthy system is a challenging task for the right operation of the system as well as system’s acceptance from the users’ perspective. Ensuring well-placed trust always depends on the trustworthiness of the trustee, i.e....

Trust is expected to reduce transaction costs and agency costs and thus influence the cost of credit for small businesses. Assessments of trustworthiness are based on the ability, benevolence and integrity of the owner manager. The study examines whether lending managers’ assessments of the trustworthiness of SME owner managers are associated with the interest rate charged. Data were obtained f...
