The invention belongs to the field of public safety, particularly relates to a novel network anti-fraud active inspection and early warning system, and aims to solve the problem of poor prevention robustness of a network and telephone fraud prevention technology. The system comprises: an automatic inspection module configured to construct a fraudulent clue clustering space; an online discrimination module which is configured to obtain the total probability association distribution of the first information of the theme leader and the affiliated member in the suspicious fraud clue through topological sorting and conditional distribution sampling; a credibility evaluation module which is configured to evaluate the suspicious fraud clues through a hierarchical label-free network comprehensiveevaluation method; and an active early warning module which is configured to actively push the suspicious fraud clue of which the weight is greater than a set early warning threshold to a mobile phoneor a case checking system of anti-fraud department personnel, and start electronic supervision for checking the suspicious fraud clue in a limited period. According to the invention, through activelycapturing the network and telephone fraud interaction structure and locking the fraud clue, the robustness of preventing the network and telephone fraud is improved.
