Problems solved by technology

[0004] However, the actual effect of the above-mentioned scheme depends heavily on the personal experience and personal ability of the makers of the scoring mechanism, and is inevitably subject to the subjective cognition of the makers, so it is easy to cause misjudgments and missed judgments, and the recognition cannot be achieved. Accuracy requirements for malicious users

Abstract

The invention provides a method and device for recognizing malicious users, and belongs to the field of network technology. The method includes the steps that historical behavior characteristics of a user to be recognized are acquired; a user classification model is acquired, wherein the user classification model is generated through classifier model training based on historical behavior characteristics of malicious users and historical behavior characteristics of normal users; the historical behavior characteristics of the user to be recognized are input into the user classification model to determine whether the user to be recognized is a malicious user or not. Through the user classification model obtained through classifier model training, the behavior characteristics of malicious users can be automatically analyzed according to the characteristics of a machine learning algorithm; compared with the prior art, the method and device have the advantages that the recognition process is independent of the subjective cognition of the human, and the coverage scope of behavior characteristics is wider, so that misjudgment and missed judgment are effectively reduced, and the accuracy of recognizing malicious users is improved.

Description

technical field [0001] The present disclosure relates to the field of servers, and in particular to a method and device for identifying malicious users. Background technique [0002] With the development of network technology, network servers can provide information services for a large number of access users in parallel by virtue of their powerful processing performance, such as software downloads, online chat, online shopping and so on. However, among the users who access the network server, there are often some malicious users who use technical means to damage the rights and interests of others. For example, the snap-buying of online commodities in online electronic malls is an emerging commodity sales method, which can play a role in promoting new products and attracting high-loyalty users. Damage the rights and interests of sellers and other consumers. [0003] In order to effectively stop the behavior of malicious users, there are some schemes that can identify malic...
