Telecommunication fraud method for virtual number segments

Abstract

The invention discloses a telecommunication fraud method for virtual number segments. The method includes the following steps that: the telecommunication fraud case data of the police and the communication data of an operator are obtained; data matching is carried out, so that an initial training set can be obtained; a random oversampling method is adopted to obtain positive and negative class equilibrium samples; the positive and negative class equilibrium samples are trained, so that a prediction model can be obtained; and the virtual number segment incoming call number communication characteristics of a user are introduced into the prediction model, so that a judgment result can be obtained. According to the method of the invention, the basic training samples are generated according to the existing communication data and the case data of the public security bureau; an Adaboost model is adopted to train samples based on the basic training samples, so that the telecommunication fraud judgment model can be obtained; calls are judged according to the judgment model; and therefore, with the method adopted, whether a virtual number segment is a telecommunication fraud can be judged accurately and fast according to the virtual number segment. The method has the advantages of high judgment accuracy, quick and convenient calculation and high applicability.

Description

technical field [0001] The invention specifically relates to a method for judging telecommunication fraud aimed at a virtual number segment. Background technique [0002] With the development of the country's economy and the improvement of people's living standards, my country's telecommunications industry has developed very rapidly. By the end of 2015, the number of telephone users in my country had reached 1.537 billion, of which mobile phone users had reached 1.306 billion, and 4G users had reached 386.225 million. China has become the world's largest communications power. [0003] However, with the rapid development of the telecommunications industry, various criminal activities using the convenience of modern communication technology and settlement methods are also rampant. At present, there are more and more methods of telephone fraud, many of which are hard to detect; in addition, due to the maturity of communication technology and the application of various telecomm...

Problems solved by technology

[0004] At present, telephone fraud is mainly disclosed through the media and social propaganda to make people vigilant to prevent it. This method relies too much on people's subjective judgment. Therefore, the current telecom fraud, especially the virtual number segment Telecom fraud, it is not particularly easy to distinguish, this kind of fraud may still endanger people's life and work
