Black product user identification method and system, electronic equipment and storage medium

Abstract

The invention provides a black product user identification method and system, electronic equipment and a computer readable storage medium, and aims to solve the technical problem of low black product identification accuracy, the method comprises the following steps: collecting user data and processing to obtain a local user data set; setting a target function of a local identification model, and training by using local user data containing black product labels to obtain a coefficient of the target function; encrypting data containing user attribute information in a local user data set, uploading the encrypted data and the trained local identification model to a federated learning platform, carrying out joint modeling on the data, identification models uploaded by other operators on the platform and the encrypted user data set, and training to obtain a joint model coefficient; according to the joint model coefficient, updating the coefficient of the local identification model objective function; and performing black product user identification on local user data. According to the technical scheme, more accurate black product user identification is provided for clients under the condition that user privacy and data security are guaranteed.

Description

technical field [0001] The present disclosure relates to the technical field of network security, and in particular to a method for identifying illegal users, a system for identifying illegal users, an electronic device, and a computer-readable storage medium. Background technique [0002] Illegal users in the network include users who steal normal user information, users who maliciously brush likes, comments or fans, users who trade pornography, users who maintain professional accounts, users who post links in groups, and users who defraud. The behavior of illegal users is serious. It affects the normal experience of users and brings major hidden dangers to the healthy development of the network. For the healthy and sustainable development of the network and the improvement of user experience in the network environment, it is necessary to identify illegal users for governance. [0003] At present, the governance of black industry mainly relies on technical means such as in...
