Social big data oriented trust situation risk model based on individual behavior

Abstract

ABSTRACTThe individual's social behavior is diverse in the big data environment, which makes the general trust evaluation model to take into account inaccuracy and causes some new problems for individual trust. Based on this, we present the trust situation risk model based on individual behavior oriented social big data. First, we use Multi data fusion to get the result of trust evaluation, then fuse the mass function of the individual trust associated with trust evaluation with the evaluation results by using the theory of D-S. Next, we get the probability of the individual appearing as distrust situation. Each related individual distrust situation is obtained by the fusion with the situation factor. According to each related individuals' trust situation, we can get the fusion of weight about each individual participating in the trust evaluation. On the basis of the above, the trust model evaluating the individual behavior is developed, the experiment shows the performance of the proposed model in this paper.
