E-commerce has grown rapidly worldwide over the course of the past five years. Despite appearance, ecommerce industry is faced with many challenges, among which trust is the biggest issue. In this paper, we take China’s largest C2C e-commerce platform–Taobao– as an example and focus on two disadvantages of current trust model: trust is easily manipulated by defrauders and trust dimensions prove...

With the expansion of the Internet, Trust has attracted the attention of more and more researchers. This paper focuses on the trust transitivity problem and proposes a trust transitivity model based on Dempster-Shafer Theory. In our model, we show two types of trust relationship: Identity Trust and Behavior Trust based on Directness Trust and Recommendation Trust. Then we build the trust transi...

With the introduction of web services, users require an automated way of determining their reliability and even their matching to personal and subjective preferences. Therefore, trust modelling of web services, managed in an autonomous way by intelligent agents, is a challenging and relevant issue. Due to the dynamic and distributed nature of web services, recommendations of web services from t...

Based on Bayesian network theorem, the paper proposed the novel trust model of P2P network named Trust-BT. The novel new Trust-BT model is based on the P2P network nodes’ history of all types of transactions, prior experience, the use of Bayesian statistical analysis methods calculate the global trust value of every network node, select the node with high trust value node transactions. The math...

In this paper, the results of a validation experiment for two existing computational trust models describing human trust are reported. One model uses experiences of performance in order to estimate the trust in different trustees. The second model carries the notion of relative trust. The idea of relative trust is that trust in a certain trustee not solely depends on the experiences with that t...

Online Social Network (OSN) is an online social platform that enables people to exchange information, get in touch with family members or friends, and also helps as a marketing tool. However, OSN suffers from various security and privacy issues. Trust, fundamentally, is made up of security with hard trust (cryptographic mechanism) and soft trust (recommender system); user's trustworthiness for ...

“Trust is a fashionable but overloaded term with lots of intertwined meanings” [1] and it has therefore been argued that trust is bad for security. We have designed, developed and evaluated a rich, semantic, human-centric model of trust that can handle the myriad of terms and intertwined meanings that defining trust has. This model of trust can be personalised on a per user basis and specialise...

All security services rely to a great extent on some notion of trust. However, even today, there is no accepted formalism or technique for the specification of trust and for reasoning about trust. Secure systems have been developed under the premise that concepts like “trusted” or “trustworthy” are well understood, unfortunately without even agreeing to what “trust” means, how to measure it, ho...
