User behavior identification method and device, storage medium and server

Abstract

The embodiment of the invention discloses a user behavior recognition method and device, a storage medium and a server, and is applied to the technical field of information processing. The user behavior identification device can determines comprehensive feature information of the to-be-identified user based on the plurality of service scenes according to the user service data of the user to be identified in each service scene in a plurality of service scenes, determines reason association features between the to-be-identified user and the plurality of types of specific users according to the comprehensive feature information, and determines whether the to-be-identified user is a specific user or not by a pre-trained identification model according to the reason association features. The user behavior recognition device needs to preset sample features of multiple types of specific users, and the sample features are generally relatively fixed, so that finally, the identification of the to-be-identified user is relatively accurate; and the comprehensive feature information obtained by integrating the user service data of the to-be-identified user in the plurality of service scenes canbe obtained, so that the actual situation of the user in the service operation process is described more comprehensively and accurately.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a user behavior recognition method, device, storage medium and server. Background technique [0002] Any user can carry out various business processes between the application terminal and other application terminals or with the application server, such as registration, login, friend request and transaction through the application terminal. In these processes, it is necessary to identify whether it is a malicious user or hacker users, so as to restrict and crack down on the business of malicious users and hacker users' application terminals. [0003] An existing user behavior identification method mainly includes: for the information of user behavior corresponding to the service request, according to the weight value of the preset user credible behavior, the historical cumulative number of service requests initiated by the user to be identified, and the The...

AI Technical Summary

Problems solved by technology

[0004] In the existing user behavior identification methods, security personnel are required to preset the weight value of the user's trusted behavior in the system based on experience and understanding of the business, so that the final identification of whether there is a risk also requires the experience of security personnel etc., the cost is high, and it is difficult to deal with the malicious prevention and control of complex business scenarios
