A telecommunication fraud gang clustering method and a telecommunication fraud gang clustering system based on a DBSCAN algorithm

Abstract

The invention relates to a telecommunication fraud gang clustering method and a telecommunication fraud gang clustering system based on a DBSCAN algorithm. The method comprises the steps of obtainingthe suspicious communication data; analyzing called party data in the suspicious communication data to obtain calling party data corresponding to the called party data; taking the collected data of each calling party as a telecommunication network node, and forming a telecommunication network node set in a predetermined area; judging whether each telecommunication network node in the predeterminedarea is a core point or not so as to find out all the core points in the predetermined area; finding out boundary points and noise points in a predetermined area according to each core point; and deleting the noise points, and forming a telecommunication fraud gang cluster according to all core points and boundary points in the predetermined area. Based on the DBSCAN algorithm, the telecommunication fraud gang cluster existing in any shape can be found, the whole telecommunication fraud gang can be eradicated at a time, and the real-time and effective fraud early warning and the low-cost treatment are achieved.

Description

technical field [0001] The invention relates to the technical field of communication information security, in particular to a telecommunication fraud gang clustering method and telecommunication fraud gang clustering system based on the DBSCAN algorithm. Background technique [0002] In recent years, various fraud incidents have emerged one after another, causing huge economic losses to the society. Among them, in the telecommunications fraud incident, the criminals fabricated false information through the Internet, phone calls and text messages, set up scams, carried out remote fraud on the victims, and induced the victims to make money or transfers to the fraudsters. Although local public security organs have been promoting the work of cracking down on telecommunications fraud, domestic and foreign fraud gangs can continue to commit fraud through the latest fraud methods. [0003] According to statistics, there are various forms of telecommunications fraud currently activ...
