Account theft risk identification method, identification device, and prevention / control system

摘要

The present application provides an account theft risk identification method, identification apparatus, and prevention / control system. The method includes the steps of collecting device information of a logon device of operation behavior, obtaining all user identity information regarding a plurality of past operation behaviors on the device within a predetermined period prior to the operation behavior, and each user Analyzing the identity analysis location, calculating the number of user identity analysis locations on the device during the period, and determining whether the current operational behavior has an account theft risk. The apparatus has a device information collection module, a user information acquisition module, a user identity analysis module, and an account theft risk evaluation module, and the user identity analysis position on the device in a predetermined period prior to the current operation behavior. Whether or not the current operation behavior has an account theft risk can be determined according to the number. The system employs a device that evaluates the risk level according to the number of user identity analysis locations to enable more effective account theft risk identification and processing, thereby providing a secure network environment for the user. .
