The system comprises a model establishment module, a branch process unfold module, a dependence relationdetermination module, a three-dimensional graph establishment module and a consistency analysis module. The analysis method comprises: establishing a user transaction PN machine model according to user behavior motion trajectories; respectively establishing branch process unfolds BPUi and BPU 2 of the user transaction PN machine model and an expected model; analyzing a behavior dependence relation between transitions inbranch process unfolds from an angle of behavior motion and determining a behavior dependence relation Ri; respectively establishing behavior relation three-dimensional graphs of the two models according to the determined behavior dependence relation; and comparing and analyzing the two behavior relationthree-dimensional graphs, calculating a user behavior consistency degree and detecting a consistency degree between a user behavior and an expected behavior. By adopting the analysis method and system, the behavior consistency in a user transaction process can be judged to judge the legality of a user accordingly.
