Abstract

The invention discloses a fraud gang prediction method, and the method comprises the steps of: obtaining abnormal account information, and determining abnormal nodes in a corresponding relation node graph of the abnormal account information; screenign other nodes in the relation node graph according to a preset risk propagation algorithm and the abnormal nodes to obtain a suspicious node set, wherein the other nodes are nodes except the abnormal nodes in the relation node graph; and inputting the suspicious node set into a pre-trained fraud gang prediction model, and controlling the fraud gang prediction model to perform classification extraction processing on the suspicious node set to obtain a node set corresponding to a fraud gang.

Description

technical field [0001] The invention relates to the field of anti-fraud technology, in particular to a method for predicting fraud gangs and related equipment. Background technique [0002] With the rapid development of the Internet, telecom fraud occurs frequently. Telecom fraud is a method of fraud based on telephone and Internet platforms. At present, the main anti-fraud method is based on the experience and lessons of anti-fraud strategy personnel, and formulates anti-fraud rules by analyzing the characteristics and operations of historical fraudulent users. When the user's operation request and behavior trigger the anti-fraud rules, it will be identified as a fraudulent behavior and interception will be initiated. The anti-fraud rules are mainly based on the degree of behavior aggregation. [0003] However, this scheme also has strong defects. When it is already known that a certain account is used by a fraudulent user, in order to find the fraudulent group, fraud det...
