Trust propagation in social networks is a challenging task. It is difficult to model human trust, and the data is huge and very sparse. Due to these challenges, the algorithms available to propagate trust have complexity issues. We used the MRFTrust algorithm created by Tosun and Sheppard to produce an anytime algorithm for trust propagation. To do this we use sampling techniques and increased ...

As a new media, social network gains a wide range of social influence, and the social network based ecommerce becomes more and more popular, therefor, the study of information propagation is great of significance. In this paper, we will presents a trust based information propagation model, just as the trust between people in real life. First, employ the algorithm of data mining on personal info...

The possibility of a massive, networked infrastructure of diverse entities partaking in collaborative applications with each other increases more and more with the proliferation of mobile devices and the development of ad hoc networking technologies. In this context, traditional security measures do not scale well. We aim to develop trust-based security mechanisms using small world concepts to ...

The article deals with a problem of modelling and propagating trust in trust networks (social networks, recommender systems, integrating systems). We briefly recall some of the solutions and approaches proposed by other authors and we focus on a trust model based on IFS theory (Atanassov’s intuitionistic fuzzy set theory). Then we present a draft of a method of calculating trust propagation wit...

In this paper, we propose a trust-based message propagation and evaluation framework to support the effective evaluation of information sent by peers and the immediate control of false information in a VANET. More specifically, our trust-based message propagation collects peers trust opinions about a message sent by a peer (message sender) during the propagation of the message. We improve on an...

The growth in knowledge sharing enabled by the (Semantic) Web has made trust an increasingly critical issue. Based on explicit inter-agent trust relations, a trust network emerges on the (Semantic) Web in the knowledge sharing context. The concept of a trust network and its application to knowledge sharing have received recent attention but neither their structural properties (e.g. dynamics, co...

The performance of ad hoc networks depends on the cooperative and trust nature of the distributed nodes. To enhance security in ad hoc networks, it is important to evaluate the trustworthiness of other nodes without centralized authorities. In this paper, we present an information theoretic framework to quantitatively measure trust and model trust propagation in ad hoc networks. In the proposed...

Trust mechanism will be an important trend in the field of security for open network. But, as an important factor risk is little considered in trust model. In this paper, Further works are done in trust and risk separately. In course of trust propagation, direct interaction information of the middle recommendation node is presented, which expresses the importance of subjective factor. About ris...

Analysis of the trust network proves beneficial to the users in Online Social Networks (OSNs) for decision-making. Since the construction of trust propagation paths connecting unfamiliar users is the preceding work of trust inference, it is vital to find appropriate trust propagation paths. Most of existing trust network discovery algorithms apply the classical exhausted searching approaches wi...
