Abstract

The invention relates to artificial intelligence, and provides an abnormal user detection method and device based on clustering analysis, equipment and a medium. The abnormal user detection method based on clustering analysis comprises the steps of obtaining basic data corresponding to each user from a preset database; performing feature extraction on the basic data according to a preset requirement to obtain feature data; performing one-hot encoding on the feature data to generate user portrait behavior data corresponding to each user; performing clustering analysis processing by utilizing all the user portrait behavior data to obtain a normal clustering group; calculating the matching degree between each piece of user portrait behavior data and the normal clustering group, and judging whether the matching degree is abnormal or not; and determining the user corresponding to the user portrait behavior data with the abnormal matching degree as an abnormal user. The invention further relates to a blockchain technology, the basic data can be stored in the blockchain, and the technical scheme of the invention realizes accurate identification of abnormal users and identification efficiency.

Description

technical field [0001] The present invention relates to artificial intelligence, in particular to a method, device, equipment and medium for abnormal user detection based on cluster analysis. Background technique [0002] With the development of network technology, Internet financial risks are more concealed and easy to expand than the rule-based strategies used by traditional finance. Due to the phenomenon of fraud by abnormal users, the welfare of ordinary consumers is robbed, and even losses are caused to enterprises. In order to To protect the legitimate rights and interests of enterprises and ordinary consumers, it is necessary to identify abnormal users. The traditional method of identifying abnormal users is mainly based on rules and login verification risk control methods, but there is a problem of low identification accuracy. Contents of the invention [0003] Embodiments of the present invention provide a method, device, device, and medium for detecting abnormal ...
