Telecommunication fraud detection method and system based on bidirectional gating cycle unit

Abstract

The invention discloses a telecommunication fraud detection method and system based on a bidirectional gating cycle unit, and the method comprises the steps: enabling an identification ID corresponding to obtained text data to matcj the same identification ID in an hbase distributed database, and recognizing whether the text data is fraud information or not; if matching is not successful, establishing a neural network model based on a bidirectional gating cycle unit, introducing a dropout algorithm into the neural network model for optimization to obtain a telecommunication fraud detection model, setting a softmax classifier in the telecommunication fraud detection model, obtaining a classification type according to an output result of the softmax classifier, identifying fraud information,and and storing the fraud information and the corresponding type into an hbase distributed database, and sending early warning information to a user side. According to the technical scheme, the technical problems of small telecommunication fraud data storage space, poor data updating speed, poor stability and poor detection effect can be solved.

Description

technical field [0001] The present application relates to the technical field of telecommunications fraud detection, and in particular to a telecommunications fraud detection method and system based on a bidirectional gated recurrent unit. Background technique [0002] In today's information society, incidents and cases of telecom fraud occur frequently, and the means of telecom fraud emerge in endlessly. Among them, the victims include ordinary people, business owners, civil servants, school teachers, etc. All walks of life may become telecom fraud Victims of fraud have a wide spread and bad social impact. Therefore, how to effectively identify telecommunications fraud information has become one of the hotspots of social research. [0003] In recent years, for the problem of telecom fraud, the most common detection methods are generally manual marking, or marking dangerous or fraudulent calls on the mobile phone security software. However, this method has many shortcomings,...
