The analysing content of comprehensive analysis module is described in detail below：
Swindle Stock discrimination：It is analyzed according to determining and doubtful swindle calling number, determining swindle caller number
Code is the calling number for having fraudulent act in anti-swindleness system, beating fraudulent call and having hit interception template；Doubtful swindle caller
Number is the doubtful swindle calling number come out by the specific law-analysing in ticket, according to this two-part number from original
The analysis mining of big data is carried out in daily record, wherein, telecommunications speech communication more detailed logging, anti-swindleness system-based data, circuit domain day
Will, short message, multimedia message and internet daily record can serve as dimension to analyze；
Swindle population analysis：After identification swindle group, group can further be analysed in depth, analysing content is melted including clique
Conjunction, clique's development trend, clique's institutional framework, the called distribution of swindle, group's geographical distribution, harassing and wrecking law-analysing, clique's success
Rate, member's liveness swindle the offline division of labor in group, swindle group member feature, swindle group track, swindle group multidimensional pass
Join retrieval analysis；
Victim analyzes：Whithin a period of time, a number is conversed with multiple harmful callers, and (response time is more than one
Fix time, such as 1 minute), transmitting-receiving short message (and in short message include particular keywords) when behaviors, substantially it can be assumed that this number
Code is number of being taken in, based on fooled people can to historical behavior, doubtful fooled people's feature, trace to the source, information profiteering, remind, caller point
Analysis is further analyzed；
Swindle scene analysis：The structure of itself may differ inside institutional framework and clique based on certain swindle scene
Sample, the institutional framework and role swindled in scene can flexibly be extended, such as air ticket according to different analysis models
The scene of swindle is compensated, gang member 1 is likely responsible for collecting the user information of booking, 3 counterfeit airline of member 2 and member
Customer service make a phone call or send short messages to booking user, be known as aircraft it is late can give reparation, it is desirable that user provide bank card
Number etc. information, obtain after these privacy informations member 4 into pirate brush, had the characteristics that according to gang member it is identical called, and
The duration of call is more than specific time, is analyzed in conjunction with short message and voice, determines that how many member of this swindling gang participates in,
It is any role respectively；
Swindle anticipation analysis：It is checked numbers by behavioural characteristic of checking numbers, the analysis of swindle scene and lasting behavioral value
It is analyzed, completes number from white list upgrades to gray list, gray list upgrades to blacklist, number is added in the work(such as clique
Energy；
Swindle event regression analysis：For known swindle number and fooled people's number, related words are obtained with reference to swindle scene
List, recording, short message, multimedia message record, when being realized in conjunction with daily record data of the mobile Internet with base station location to swindle event
Between, the full backup of space and content；
Swindle case analysis：Realize multiple cases in incident time, incident by the polymerization analysis between multiple cases
The incidence relation in space, member's number, connected component etc., and show that the association between case is closed by visualization technique
System；
Black production Source Tracing：Black production information source tracing is completed by customizing black production communication feature and the behavioural analysis of depth number
Function, wherein, it customizes black production communication and is characterized as by manually customizing key feature and the flow that black production communicates, including calling number
Ownership place, calling number feature (including optional network specific digit, sequence etc.), the duration of call, called number possession, called behavioural characteristic
The crucial ginseng such as (clawback dials specific number), short message, multimedia message, mobile Internet daily record and all kinds of durations, Ct value
Number, by the customization of model, present system carries out the black production of mining analysis completion according to model parameter and traces to the source；Depth number behavior
Analysis is carried out the scene of swindle as starting point using victim, and Source Tracing is carried out based on victim, analyze victim call,
The user behaviors logs such as short message, mobile Internet, at the same analyze with the associated swindle group of victim, from the communication of group member
Analyse whether that there are the role of third party service provider presence in record.
Present invention performance indicator when in use is：External system obtains, the time delay of parsing is no more than 1 minute；It is right daily
Multi-source data carries out swindle population analysis, and swindle group was found in 1 hour；It is small 1 daily to the depth analysis of swindle group
When interior completion analysing content；Clique is calculated in real time for analysis model, from external data is obtained to generation clique's time
Less than 30 minutes.
As depicted in figs. 1 and 2, the present invention is by obtaining anti-swindleness system, Mobile Internet system, short MMS system and being based on
The log data and analysis result of the fraud analysis system of behavioural characteristic and scene carry out comprehensive analysis, are cheated for communication information
Comprehensive precaution offer technology and data supporting are provided.Wherein, user of the service-user as the present invention can inquire the present invention point
Analysis it is all as a result, analysis can be configured, the operations such as adjusting thresholds；Anti- swindleness system includes the daily record of telecommunications ticket, VOIP is talked about
Odd-numbered day will, determining swindle calling number and all kinds of list datas are the main log data that the present invention analyzes；Mobile Internet
System includes the internet behavior daily record of mobile phone user and the user behaviors log of circuit domain, and mobile Internet daily record includes mobile phone
Number, the information such as IMSI, IMEI, URL, APP type, base station location, ownership place, circuit domain daily record includes cell-phone number, type of action
The information such as (switching on and shutting down receive and dispatch short message, take phone, position movement etc.), other party number, base station location, ownership place, mobile interchange
The correlation log of net system is the important log of various dimensions association analysis of the present invention；Short MMS system provides mobile phone and service
The short multimedia message log of number includes cell-phone number, other party number, operator, ownership place, base station location, short breath content etc., short multimedia message
Daily record be various dimensions association analysis of the present invention important log；The fraud analysis system of Behavior-based control feature and scene, which provides, doubts
As swindle calling number, for the present invention swindle population analysis significant data is provided；Anti- swindleness system, analysis result of the invention
Available for the foundation of each provincial anti-swindleness system setting list, the gray list of anti-swindleness system is such as added to, dialog context is recorded
Sound further determines that the accuracy of doubtful swindle caller and timely switchs to blacklist interception；Collaborative linkage system, the present invention
Analysis result (such as swindling caller, high-risk susceptible number result data) is pushed into collaborative linkage system, system, state in each province
The shared of data is carried out between the port system of border, achievees the purpose that collaboration is taken precautions against；Public security system, the present invention provide swindleness for public security system
Caller, the push for user data of being taken in are deceived, is given a clue to put on file for investigation and prosecution；Public user, analysis results of the invention are to granddad
Cloth provides all kinds of swindle scenes, the analysis of case and statistical data for public user.
Compared with prior art, the advantages of the present invention are：
