Abstract

The invention discloses a method for detecting international piracy, which is characterized in that the method comprises the following steps: S1, reading data; extracting original CDR telephone bill data in international outgoing call from informix database; S2: Feature engineering: performing preliminary screening on the original CDR call order data and obtaining the call behavior characteristics; S3, model detection: adopting isolated forest algorithm and user-defined algorithm to detect and judge whether the number based on the characteristics of the call behavior exists stealing behavior or not; S4: Weighted summation judgment: the isolated forest and the result of the user-defined algorithm are weighted and summed, and each number corresponds to a threshold value after weighting. Thethreshold value is equal to or greater than the abnormal number, and the threshold value is less than the normal number. The invention has the beneficial effects that the abnormal telephone detectionmethod can effectively reduce the occurrence rate of international settlement and the workload of manual examination, thereby avoiding the economic loss of users to the maximum extent, reducing the occurrence rate of international settlement, and providing reliable call service for telephone users.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method for detecting international piracy. Background technique [0002] With the development of communication technology, more and more criminals use software and hardware to steal user communication numbers to call foreign charging platforms through communication technology, so that many phone users will generate abnormally high international call charges, not only to Users have brought economic losses and disturbed the normal social order. [0003] Telephone users hope to have a safe call environment to reduce and eliminate the occurrence of international piracy; national security departments, public security and other government departments, and telecom operators also hope to crack down on set settlement behaviors through technical means, so as to provide the public with a safe and credible call environment. Contents of the invention [0004] Aiming at the problems...
