Abstract

The embodiment of the invention discloses a method and device for identifying an abnormal behavior user. A specific embodiment of the method comprises the steps of obtaining the operation informationof an operation executed on a target application by a user in a preset user set in a target time period; based on the obtained operation information, generating a frequent pattern tree, wherein a pathof the frequent pattern tree is used for indicating an operation sequence executed on the target application by the user in the preset user set in the target time period; and based on the frequent pattern tree, identifying the abnormal behavior users from the preset user set. According to the embodiment, by generating the frequent pattern tree, the abnormal behavior users in the user set are determined based on the operation sequence executed by the users, and the situations that the operation of the target application is abnormal, the abnormal behavior users earn the profits illegally and the like caused by the operations of the abnormal behavior users, are avoided.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to a method and device for identifying users with abnormal behavior. Background technique [0002] Traditional anomaly detection for identifying users with abnormal behaviors usually detects intrusion behaviors based on abnormal behaviors (system behaviors or user behaviors) or use of abnormal computer resources, and then determines users with abnormal behaviors. The key is to establish the user's normal behavior profile (Profile), and judge whether it deviates from the normal profile by detecting the actual activity. [0003] Existing anomaly detection algorithms mainly construct continuous features. For normal users, the distribution is usually relatively concentrated on each feature dimension; however, for users with abnormal behavior, it may appear on a specific feature distribution outliers. [0004] The current anomaly detection algorithm mai...
