چکیده

With the rapid development of online reputation systems, manipulations against such systems are evolving quickly. In this paper, we propose a Dempster-Shafer theory based trust scheme to protect reputation systems. When tested against real user attack data collected from a cyber competition, the proposed scheme has achieved a very good performance in terms of accurately identifying malicious users. It also demonstrates a great potential to effectively remove dishonest ratings and keep the online reputation system a secure and fair marketplace.

In this paper, a new Fuzzy Morphology (FM) based on the GeneralizedDempster-Shafer Theory (GDST) is proposed. At first, in order to clarify the similarity ofdefinitions between Mathematical Morphology (MM) and Dempster-Shafer Theory (DST),dilation and erosion morphological operations are studied from a different viewpoint. Then,based on this similarity, a FM based on the GDST is proposed. Unlik...

To cope with these attacks, existing trust models employ different trust aggregation techniques to process the recommendation trusts and combine them with the direct trust values to form a combined trust value. However, these trust models are biased as recommendation trusts that deviate to...

As e-communities grow in both quality and quantity, their online users require more appropriate tools to suite their needs in such environments.

AModel for Augmenting Trust Management using Argumentation

Previous work has used theories of evidence to incorporate belief into trust and reputation systems. Some important questions that remain, however, are how agents might recover reputation lost in disputed transactions, and how new agents with little or no past transaction history might enter the trust network. We attempt to address these issues by extending previous work using the Dempster-Shaf...
