Embodiment Construction

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0042] At present, telecom anti-fraud methods are mostly carried out by operators or Internet companies by analyzing their own user data to mark fraudulent calls. Since each company can only master and use its own user data, the amount of data is insufficient for analysis, and the false negative and false negative rates of fraud call identification are high. Aiming at the technical problem that the current telecom anti-fraud technology has isolated data and cannot carry out data linkage, thereby affecting the recognition accurac...

Abstract

The invention provides a phone fraud recognition method and system, and aims to solve the problems of data isolation and low accuracy in phone fraud recognition in the prior art, the method comprises the following steps: each participant node regularly sends user ID data and label data in a blacklist maintained by each participant node to a management node; the management node finds out the label data with the same ID and determines whether a label marked as a fraud call exists in the label data with the same ID, and if so, instructs the related participant node to update the label corresponding to the ID in the local blacklist to the fraud call; when each participant node finds out a suspected fraud phone number, the participant node obtains the ID corresponding to the phone number, and then queries the corresponding label data in the local blacklist by using the obtained ID so as to identify whether the phone number is a fraud call. According to the technical scheme provided by the invention, the phone fraud is accurately and efficiently recognized through a data fusion technology, and meanwhile, data privacy protection is realized.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method for identifying fraudulent calls and a system for identifying fraudulent calls. Background technique [0002] Due to the various means of committing crimes, low cost of committing crimes, large number of victims, and difficulty in tracking, telecom fraud has attracted more and more attention and has become a serious social problem, which has also brought greater pressure from public opinion on operators. In recent years Operators have been exploring telecommunications anti-fraud technology in the past. [0003] At present, fraudulent call identification methods generally use machine learning and modeling analysis by analyzing the behavior of the number, such as modeling and analysis based on the number's call duration, online duration, number of hangups, package service subscriptions, and call frequency. Forecast, and then generate a black and gray list and send ...
