一种基于社会网络的激励兼容的信任模型
Incentive-compatible trust model based on social network
摘要
Abstract
The trust relation in the social networks is one of the most complex social relations. It is difficult to be predicted and quantized as it involves too many kinds of factors. Through considering many possible factors comprehensively from the viewpoint of social network, this paper proposed a multi-dimensions trust model, which brcught together direct-trust,indirecttrust, and risk function to describe the complexity and uncertainty of the trust relationship. In order to resist some bad entities' fallacious behaviors, designed an economical incentive mechanism in the trust model. The entities would be encouraged to collaborate honestly and actively using this mechanism. Finally, applied a cryptogram mechanism to protect securitive information in the incentive mechanism. And improved the credibility of the model in practical application. Experimental results show that the trust model can not only predicate the behavioral trust of the nodes accurately, but also keep the interaction risk in control. And the incentive mechanism can well inhibit the malicious behaviors, share the trust information and ensure sensitive information secure during data interaction.关键词
