Method, device and storage medium for identifying malicious user

Abstract

The embodiment of the invention provides a method, a device and a storage medium for identifying a malicious user. The method comprises the following steps: obtaining a training sample set, wherein the training sample set comprises features of the training sample and a tag corresponding to the training sample; using the tag corresponding to the training sample for identifying whether the user is amalicious user or not; determining the optimal segmentation features and thresholds from the training sample set, splitting the training sample set to obtain a first sample set and a second sample set, and taking the mean value of each feature of the first sample set and the second sample set as a target output value; judging whether the user is a malicious user or not according to the target output value; setting a label corresponding to a training sample determined to be a malicious user in the first sample set and the second sample set as a malicious user, and setting a label correspondingto a training sample determined to be a non-malicious user as a non-malicious user. By adopting the scheme, the behavior characteristics of users can be accurately analyzed, and malicious users can be identified according to the behavior characteristics.

Description

technical field [0001] The present invention relates to the technical field of software, in particular to a method, device and storage medium for identifying malicious users. Background technique [0002] During the development of the live broadcast platform, in order to achieve private purposes, some black production groups often register many platform accounts in batches, and use these accounts for malicious activities such as commenting, barrage, and popularity, in an attempt to increase the popularity of a certain live broadcast room. It makes the resources of the entire live broadcast platform unequal and profits from it. The live broadcast platform needs to ban the users of these malicious accounts. However, it is difficult to directly mine the behavior of malicious accounts from massive data. It is a feasible idea to use algorithms to mine malicious users. [0003] Since malicious users operate in batches of illegal products, their behaviors and actions often have c...
