An entire solution is divided into three stages: at a first stage, analyzing complex correspondence relation characteristics according to an existing user behavior model; at a second stage, establishing a behavior profile according to user behavior characteristics and establishing user behavior relation matrixes; and at a third stage, completing user behavior matrix decomposition according to the complex correspondence characteristics of a user, calculating a user behavior consistency degree and detecting a degree of consistency between user behaviors and expected behaviors. The internal behavior relation of the user is more elaborately analyzed, the user behavior relation profile is established, the complex correspondence relations are distinguished and classified, and user behavior consistency measurement and analysis architecture based on the complex correspondence relations are given.
