Ensuring Trust in One Time Exchanges: Solving the QoS Problem

We describe a pricing structure for the provision of IT services that ensures trust without requiring repeated interactions between service providers and users. It does so by offering a pricing structure that elicits truthful reporting of quality of service (QoS) by providers while making them profitable. This mechanism also induces truth-telling on the part of users reserving the service

Trust and Risk Relationship Analysis on a Workflow Basis: A Use Case

Trust and risk are often seen in proportion to each other; as such, high trust may induce low risk and vice versa. However, recent research argues that trust and risk relationship is implicit rather than proportional. Considering that trust and risk are implicit, this paper proposes for the first time a novel approach to view trust and risk on a basis of a W3C PROV provenance data model applied in a healthcare domain. We argue that high trust in healthcare domain can be placed in data despite of its high risk, and low trust data can have low risk depending on data quality attributes and its provenance. This is demonstrated by our trust and risk models applied to the BII case study data. The proposed theoretical approach first calculates risk values at each workflow step considering PROV concepts and second, aggregates the final risk score for the whole provenance chain. Different from risk model, trust of a workflow is derived by applying DS/AHP method. The results prove our assumption that trust and risk relationship is implicit

Trust Based Participant Driven Privacy Control in Participatory Sensing

Widespread use of sensors and multisensory personal devices generate a lot of personal information. Sharing this information with others could help in various ways. However, this information may be misused when shared with all. Sharing of information between trusted parties overcomes this problem. This paper describes a model to share information based on interactions and opinions to build trust among peers. It also considers institutional and other controls, which influence the behaviour of the peers. The trust and control build confidence. The computed confidence bespeaks whether to reveal information or not thereby increasing trusted cooperation among peers.Comment: 14 page

These works may not be re-posted without the explicit permission of the copyright holdersGovernments around the world are moving away from conventional ways of face to face communication to a more digital approach when delivering services to their citizens. This includes using the internet as both a communication tool and an information source to improve efficiency in their services. However, not all the citizens are making use of these changes, especially the older adults. Therefore, this research-in-progress paper aims to investigate and identify the factors that encourage older adults to continue using a particular communication channel when interacting with the government. In addition, future directions, limitations and conclusions are also provided within this paper. The implication of this study to academia is viewed to be the development of an extended framework that allows an understanding of continuance intention of online communication tools usage. Equally, this framework will benefit industry by informing providers of communication channels to the government to be aware of the factors that influence older adults’ choices when interacting with the government. For policymakers this research will identify the communication channels that promote interaction with citizensFinal Published versio

Local and Global Trust Based on the Concept of Promises

We use the notion of a promise to define local trust between agents possessing autonomous decision-making. An agent is trustworthy if it is expected that it will keep a promise. This definition satisfies most commonplace meanings of trust. Reputation is then an estimation of this expectation value that is passed on from agent to agent. Our definition distinguishes types of trust, for different behaviours, and decouples the concept of agent reliability from the behaviour on which the judgement is based. We show, however, that trust is fundamentally heuristic, as it provides insufficient information for agents to make a rational judgement. A global trustworthiness, or community trust can be defined by a proportional, self-consistent voting process, as a weighted eigenvector-centrality function of the promise theoretical graph

TruMet: An approach towards computing trust in multi-agent environment.

The growing popularity of multi-agent based approaches towards the formation and operation of virtual organizations (VO) present over the Internet, offer both opportunities and risks. One of the risks involved in such community is in the identification of trustworthy agent partners for transaction. In this paper we aim to describe our trust model which would contribute in measuring trust in the interacting agents. Named as TruMet, the trust metric model works on the basis of the parameters that we have identified as relevant to the features of the community. The model primarily analyses trust value on the basis of the agent¿s reputation, as provided by the agent itself, and the agent¿s aggregate rating as provided by the witness agents. The final computation of the trust value is given by a weighted average of these two components. While computing the aggregate rating, a weight based method has been adopted to discount the contribution of possibly un-fair ratings by the witness agents

Исчисление мнений: расширение репутационной модели

Репутационная аксиоматика на основе нечетких множеств обобщается до понятия схожести мнений. Дается понятие рефлексивного множества. Вводится многоуровневая репутационная модель и рассматривается возможный вид процесса распространения мнений и репутации в средах групповых (форумы, конференции) и персональных (e-mail) коммуникаций

Modelling Trust In Wireless Sensor Networks from the Sensor Reliability Prospective

This paper surveys the state of the art trust-based systems in Wireless Sensor Networks (WSN); it highlights the difference between Mobile ad hoc networks (MANET) and WSN and based on this observed difference (monitoring events and reporting data) a new trust model is introduced, which takes sensor reliability as a component of trust. A new definition of trust is created based on the newly introduced component of trust (sensor data) and an extension of node misbehaviour classification is also presented based on this new component of trust

Ontological foundations for trust management:Extending the reference ontology of trust

In this paper, we provide a semantic foundation for trust-related concepts in the light of trust management. We extend our previous work, the Reference Ontology of Trust, to clarify and provide a deeper account of some building blocks of trust, such as beliefs and intentions of a trustor, pieces of evidence that indicate that a trustee is trustworthy (or not), as well as the many factors that influence trust. We illustrate our proposal by instantiating and discussing people's trust in vaccines in the time of COVID-19.</p

BUILDING TRUST AMONG THE CLIENTS OF CLOUD COMPUTING INDUSTRY. CASE STUDY OF TRELLO, INC.

Purpose: The main objective of this paper is to identify proper practices for building clients’ trust by Trello, Inc., aimed to convince potential clients of their cloud-based services. Approach: In this paper, the case study of Trello, Inc. is used to analyze the case data, aimed to examine the causal links between actions taken to gain clients’ trust and their observed effects. Implications: This paper provides insight into building trust in Business to Business (B2B). Using cloud technologies to offer services enables a company to create innovative value proposition, or in other cases, add new features and attributes to it that cater to the clients’ needs. It involves different approach of the company in building clients’ trust than if it offered services in traditional way. To handle this issue effective trust management implementation is required. Findings: This paper provides suggestions of trust management actions which can be taken and are not limited to data security guarantee. Value of the paper: This paper underlines proper practices – based on the success of Trello, Inc. – for building clients’ trust by business where aim is to convince potential clients of enterprise’s cloud-based service.
