Abstract

A method for identifying fraudulent recorded phone calls, comprising: step 1, extracting all calling numbers from the call records of the research day, and forming a set of calling numbers to be identified; caller numbers, and then several days including the research day constitute a time period, extract the call records of each caller number in the time period, and calculate the number of communications of each caller number in the time period Index; step 3, according to the daily call frequency of the calling number, determine the daily call frequency index level to which each calling number belongs, and then according to the daily call frequency index level to which it belongs, and several communication indicators within the time period, judge Whether each calling number is a fraudulent number. The invention belongs to the field of communication, and can effectively identify fraudulent phone calls recorded with a "sound" from massive live network communication data.

Description

technical field [0001] The invention relates to a method for identifying fraudulent recorded phone calls, which belongs to the field of communication. Background technique [0002] At present, there are mainly three ways to lure the first step of fraud: one is that criminals post small advertisements on the street or post online, and the victim initiates a call to the criminals after seeing the fraudulent information; Induce the victim to be deceived; the third is that the criminal dials a "ring" phone, and the victim hears the fraudulent voice message and the contact information of the scammer when calling back. The first method is that the victim actively calls out, and it is difficult to fortify; the second method cannot carry out effective verification work; therefore, how to effectively identify the third method (that is, "one ring" recorded fraud phone call from the massive live network communication data) ), has become a technical issue of general concern to technici...
