The invention belongs to the technical field of network space security, and discloses an information concealment access method based on behavior confusion, a system, and a server; including data collection, data storage, data analysis, access preparation, user access request check, selection of virtual identity, selection of access Links, visit target pages, return visit results, select a large number of virtual user models, obtain a large number of simulated access links and simulate the real social behavior process of a large number of virtual users. The invention realizes the modularization of each functional component, and the functional responsibility of each module is clear; the binding relationship between identity and behavior is avoided, and the leakage risk of user identity information and behavior intention is reduced. The present invention establishes virtual user identities and virtual access links by analyzing network real user identity information and behavior data, maintains a large number of virtual user access behaviors, confuses real user identity information and access intentions, and realizes the purpose of information concealment access.
