Subjective Trust Model in Distributed Network

Yulong Liu

Abstract

Abstrcat To solve the complex and dynamic trust relationships in distributed network, subjective trust model is proposed. Trust quantification and propagation methods are investigated. The meaning of subjective trust and the factors influencing trust behavior are discussed. The relationship of trust and trust attributes is investigated. A definition of relative experiment is presented. Based on the definition and Beta distribution, a novel subject trust model is proposed, and an algorithm to combine recommendation trust is illustrated. The trust updating protocol is presented to adjust trust relationship.
