Embodiment Construction

[0041] In order to effectively identify illegal accounts and improve system security, in the embodiment of this application, the risk index of the account is evaluated based on the number of natural persons corresponding to the mobile phone number bound to the account, so as to accurately screen out abnormal accounts that pose a threat to system security .

[0042] Preferred implementations of the present application will be described in detail below in conjunction with the accompanying drawings.

[0043] In practical applications, many hacking gangs in e-commerce systems will sell stolen goods by setting up multiple seller accounts, and in order to facilitate management and control, hacking gangs usually bind these multiple seller accounts to the same or fix several mobile phones Number. Through the sampling and analysis of massive data, an obvious rule was discovered: the number of different natural persons bound to a mobile phone number can be used as the basis for determi...

Abstract

This application relates to a computer system, and provides a method and device for assessing account risk, which are used to effectively identify illegal accounts, thereby improving system security. The method is as follows: the management server determines the risk level of the mobile phone number according to the number of natural persons bound to the mobile phone number, determines the risk level of each account according to the binding relationship between the mobile phone number and the account, and determines the risk level of each account based on the risk level of each account. As well as the corresponding relationship between the preset risk level and the risk index, the risk index of each account is determined, wherein the risk index is used to represent the probability of a case occurring in the account. In this way, illegal accounts that endanger system security can be identified accurately and efficiently, thereby facilitating strict management and monitoring, and further improving the use security of the computer system in an all-round way.

Description

technical field [0001] The present application relates to a computer system, in particular to a method and device for assessing account risk in a computer system. Background technique [0002] With the development of computer technology, more and more criminal gangs have gradually begun to realize illegal activities through computer systems.
