System and method for big data analysis, confirmation and interception of fraudulent calls

Abstract

A system and method for big data analysis, confirmation and interception of fraudulent calls based on in-band and out-of-band signals. The system is composed of the following seven devices on the basis of the existing communication network: call access device, call Data acquisition device, big data analysis device, feedback confirmation device, manual review device, fraud call interception device and call monitoring device. The present invention adopts the big data processing method to analyze the calling rules of the calling party, and combines the triple confirmation method and the double interception method of the suspected fraudulent number to propose a system and method for analyzing, confirming and intercepting fraudulent phone numbers. The present invention improves It improves the call experience of phone users during the call process, and minimizes the risk of users suffering losses due to credulous fraudulent calls, thereby reducing the incidence of fraudulent calls and truly providing a safe call environment for phone users. Moreover, the adoption of the method will not affect the normal conversation of the user; it has a very good promotion and application prospect.
