Embodiment 1

[0040]The embodiment of the present invention provides a fraud phone identification method, figure 1 is a schematic diagram of the method, please refer to figure 1 , the method includes:

[0041] Step 101: Obtain the basic data of the current call behavior, and extract information related to the current call behavior;

[0042] Step 102: Calculate the first risk score V1 of the current call behavior by using the pre-established first recognition model according to the extracted information;

[0043] Step 103: Judging whether the first risk score V1 is higher than the preset first threshold F1, if the judgment is yes, execute step 104, and if the judgment is no, execute step 107;

[0044] Step 104: Calculate the second risk score V2 of the current call behavior by using the pre-established second recognition model according to the extracted information;

[0045] Step 105: judging whether the calling party of the current call behavior satisfies the predetermined condition, if ...

Embodiment 2

[0099] This embodiment provides a device for identifying fraudulent calls. The apparatus may be, for example, a piece of equipment in a service system of a telecom operator, or may be one or some components or components configured in the above-mentioned equipment. Since the problem-solving principle of the device is similar to that of the method in Embodiment 1, its specific implementation can refer to the embodiment of the method in Embodiment 1, and the same content will not be repeated.

[0100] figure 2 is a schematic diagram of the device 1000, as figure 2 As shown, the device includes a first extraction unit 1001, a first calculation unit 1002, a second calculation unit 1003, a first judgment unit 1004, a third calculation unit 1005, and a decision unit 1006, and the first extraction unit 1001 obtains the current call behavior Basic data, extracting information related to the current call behavior; the first calculation unit 1002 uses the pre-established first recog...

Embodiment 3

[0116] An embodiment of the present invention provides a system for identifying fraudulent calls, and the system for identifying fraudulent calls may include the device for identifying fraudulent calls described in Embodiment 2. Since the device for identifying fraudulent calls has been described in detail in Embodiment 2, its content is incorporated here, and will not be repeated here.

[0117] image 3 is a schematic diagram of the data architecture of the fraud phone identification system of this embodiment, as image 3 As shown, the fraud phone identification system has six layers, namely the basic data layer L0, the public index layer L1, the trusted identification layer L2, the deep identification layer L3, the asynchronous identification layer L4 and the decision output layer L5.

[0118] The basic data layer L0 is mainly used to collect and store call records and all information related to call records;

[0119] The public indicator layer L1 is mainly used to extract...

Abstract

A method, device and system for identifying a fraudulent call, the method comprising: acquiring basic data of current call behavior, extracting information related to the current call behavior; using a pre-established first identification model to calculate the first call behavior according to the information. a risk score; when the first risk score of the current call behavior is higher than the preset first threshold, use a pre-established second identification model to calculate the second risk score of the current call behavior according to the information; determine the risk of the current call behavior Whether the calling party satisfies the predetermined condition; when the calling party of the current call behavior satisfies the predetermined condition, use the pre-established third identification model to calculate the third risk score of the current call behavior according to the information; The risk score and / or the third risk score determines whether the current call behavior is a fraudulent call. In this way, a reasonable diversion of call traffic can be realized, and fraudulent calls can be identified in real time or in quasi real time.

Description

technical field [0001] The invention relates to the field of information, in particular to a method, device and system for identifying fraudulent calls. Background technique [0002] Telecom fraud refers to the criminal act in which criminals fabricate false information and set up scams by means of telephone, network or text messages, and carry out remote and non-contact fraud on the victim, inducing the victim to send money or transfer money to the criminal. [0003] In recent years, there has been a high incidence of telecommunication fraud, and fraud methods emerge in an endless stream. As information leakage becomes more and more serious, telecommunication fraud has begun to evolve from "spreading the net" to "precision", which will mean an increase in the success rate of fraud. At present, telecommunication fraud crimes have involved 31 provinces, autonomous regions and municipalities across the country, and the victims cover all age groups and various occupations. Acc...
