The invention discloses a behavior prediction control based trusted network group construction method, comprising the steps of: step 10, performing identity measurement on a user terminal, and rejecting access of the user terminal who cannot pass the identity measurement; step 20, performing state measurement on the user terminal passing the identity measurement, and rejecting access of the user terminal who cannot pass the state measurement; and step 30, performing behavior measurement on the user terminal passing the state measurement, and rejecting access of the user terminal who cannot pass the behavior measurement. According to the method, in a trusted group construction process, firstly whether a behavioral individual is trusted is evaluated by predicting whether individual behaviors are trusted, secondly regulations of trusted behaviors of a group are abstracted on the basis of the individual behaviors, and the individual is constricted based on the regulations of the trusted behaviors of the group, so that the individual is organically combined with the group, the individual and the group are ensured to be trusted at last, and the trusted group is constructed through trusted individuals at last.
