Account detection method and device, server and storage medium

Abstract

The invention provides an account detection method and device, a server and a storage medium. The method comprises steps of obtaining historical interaction data of the to-be-processed account; determining a feature vector of the to-be-processed account; based on the feature vector of the to-be-processed account, determining an account detection data cluster to which the to-be-processed account belongs, based on the type of the account detection data cluster to which the to-be-processed account belongs, determining the account type of the to-be-processed account; wherein the feature vector ofthe to-be-processed account is used for expressing the association between the to-be-processed account and at least one existing account; wherein the account detection data cluster is obtained based on feature vector clustering of an existing account; therefore, identification can be carried out through association between the to-be-processed account and the existing account; according to the invention, the conversion from the detection of the high-frequency behavior characteristics to the association between the detection accounts is realized, so that even if the to-be-processed account modifies the own behavior characteristics, whether the to-be-processed account is an abnormal account or a normal account can be detected through the connection between the to-be-processed account and theexisting account, and the accuracy is improved.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to an account detection method, device, server and storage medium. Background technique [0002] At present, users can become members of the multimedia platforms of various network companies by registering accounts to watch multimedia information on the multimedia platforms, and in order to promote their own multimedia platforms, various network companies will use some activities such as selling activation codes to make users Become a member, and the cost of becoming a member through an activation code is much lower than the cost of other direct membership methods. [0003] In this case, some illegal users will purchase a large number of activation codes through a certain account or multiple accounts during the event, and then sell the purchased activation codes to other users for profit. In order to combat this illegal behavior, it is possible to determine whether the...

Problems solved by technology

In order to combat this illegal behavior, it is possible to determine whether the account is an abnormal account by analyzing behavior data. If so, the account will be prohibited from obtaining an activation code, for example, by detecting a material (including mobile phone number, account number, IP and device number, etc.) Whether the number of requests is higher than that of normal accounts, if so, it is determined to be an abnormal account, but illegal users can frequently change the materials requested each time, thereby reducing the accuracy of detection
