Abstract: In recent years, a large number of social applications created new challenges to inhibit the spread of false information. And how to evaluate the threats of the false information dissemination remains one of the major concerns in the Internet security issues. Existing schemes focused on the operational safety of information systems and ignored the importance of assessment of false information dissemination. In this paper, we propose a novel method to evaluate the threat of false information dissemination. By analyzing social network application’s structure and the information transmission mode, it proposed a risk assessment model for the false information dissemination.With this model, it is easy to evaluate and estimate the level of risks in social applications. Experiment verifies the effectiveness and correctness of this model in providing security recommendations and finding the most dangerous risk point.
