Problems solved by technology

[0014] The disadvantage of the above method is that, for technology 4, the need for physical serial access to the transmission optical path brings great hidden dangers to network security. Once a device failure occurs, it will face the risk of paralyzed calls on the entire network, and the actual deployment is very difficult.

Abstract

The invention discloses a method for screening, categorizing and intercepting fraudulent samples of suspicious numbers. The method includes 1) accessing the core network and collecting call logs; 2) mining and analyzing suspicious numbers; 3) obtaining fraudulent numbers; 4) hacking The list is manually reviewed, and fraudulent calls are intercepted in real time. The present invention adopts mature keyword voice recognition technology to identify whether the suspicious number recording sample contains a predefined combination of fraudulent keywords, realizes the function of intercepting and identifying fraudulent calls, and can accurately identify illegal calls including but not limited to fraudulent voices, Then, the anti-fraud interception platform connected to the core network is used to intercept fraudulent numbers. This system is applicable to various network standards, covering the fixed communication network and mobile communication network of China Telecom, China Mobile and China Unicom, and can identify and intercept overseas fraudulent calls and domestic fraudulent calls.

Description

technical field [0001] The invention relates to the technical field of telephone security, in particular to a method and system for screening, classifying and intercepting fraudulent samples of suspicious numbers. Background technique [0002] Since 2009, phone scams have intensified. Criminals fabricate false information over the phone, set up scams, implement remote and non-contact fraud on victims, and induce victims to transfer money to criminals to defraud them of money. Compared with other crimes, telephone fraud has the characteristics of high-tech crimes, difficulty in verification, recovery, arrest, and handling. After long-term practice, the current consensus is to link departments, coordinate management, combine prevention and control, and focus on prevention. Using technical means to intercept fraudulent calls, cutting off the incentives for crimes from the source and suppressing crimes has become an important means of prevention. [0003] After research, it i...
