Problems solved by technology

However, due to the large amount of data in the operator's local bill, the current technology processes the entire bill, with slow detection speed and relatively low performance.
Moreover, using a single-level behavior matching model, the accuracy rate is relatively low
In addition, this technology also has the risk of user information leakage

Abstract

The invention provides a fraud phone identification method and system. The method comprises the following steps: obtaining a local real-time call ticket of an operator, encrypting a telephone number in the local real-time call ticket, and obtaining a corresponding desensitization call ticket; Extracting a calling number, a called number, call duration and call starting time in the desensitizationcall ticket; Analyzing the calling number, and screening out an abnormal number; Analyzing the called number corresponding to the abnormal number, and judging whether the user of the called number isa suspected victim user or not; Analyzing the specific conversation process of the abnormal number and the called number corresponding to the abnormal number, judging whether the abnormal number meetsthe fraud conformity or not, if yes, decrypting the abnormal number and the called number, and determining that the decrypted abnormal number and called number are the fraud number and the number ofthe victim user respectively; And outputting the fraud number and the victim user number. According to the invention, the identification of the fraud phone is realized.

Description

technical field [0001] The present disclosure relates to the field of information security, in particular to a method and system for identifying fraudulent calls. Background technique [0002] Traditional fraud detection methods are generally implemented based on blacklist comparison. However, due to the rapid change of fraudulent numbers, the real-time update of the blacklist cannot keep up, and the fraudulent numbers processed by the number changing software cannot be identified, so the detection effect of this blacklist comparison detection method is limited. [0003] Aiming at the above-mentioned limitations, a fraudulent call detection method based on call behavior has emerged. However, due to the large amount of data in the operator's local bill, the current technology processes the entire bill, with slow detection speed and relatively low performance. Moreover, using a single-stage behavior matching model, the accuracy rate is relatively low. In addition, this tech...
