Abstract

The embodiment of the invention discloses an abnormal account prevention and control method based on a graph structure model, a device and equipment. According to the scheme, the method comprises steps of building an appropriate account relation network in advance according to relevant data of account registration and / or authentication; carrying out feature integration and defining a graph structure model, training the graph structure model by utilizing the labeled sample, then calculating embedding vectors of multiple iterations of nodes in the hidden feature space and the prediction probability of the embedding vectors by utilizing the trained graph structure model, and carrying out abnormal account prevention and control on the nodes according to the embedding vectors.

Description

technical field [0001] This specification relates to the technical field of computer software, and in particular to a method, device and equipment for preventing and controlling abnormal accounts based on a graph structure model. Background technique [0002] With the rapid development of computer and Internet technology, many services can be conducted online. To use these services, users often need to register corresponding accounts, such as e-commerce platform accounts, third-party payment platform accounts, forum platform accounts, etc. [0003] For bad purposes, some users or organizations will automatically register accounts through machines and perform real-name authentication in batches. These abnormal accounts may bring risks to the platform and have low value to the platform. [0004] In the prior art, these abnormal accounts are usually dealt with correspondingly, such as freezing, canceling, etc., through user reporting. [0005] Based on the existing technology,...
