Fig. 3 is a kind of schematic diagram of phone number antifraud system provided in an embodiment of the present invention, as shown in figure 3, including
It counts generation module: by analyzing big data ticket information, obtaining the illegal communication by public telephone statistical information pond for different dimensions；Determine
Module: (export which dimension combination is determining whether user is doubtful by the decision criteria that decision Tree algorithms obtain various dimensions
Like fraudulent user scene in proportion it is bigger), and the illegal communication by public telephone statistical number combined according to various dimensions decision criteria
According to collection, the illegal communication by public telephone statistical data collection is determined, doubtful fraudulent user is judged whether it is；Identification module: according to number
It exports according to mining analysis module as a result, being automatically performed the identification of doubtful fraudulent user.
By analysis big data ticket information (time started, the end time, type of service, event result, business reasons,
Caller, called, bearer types, the duration of call, source office point and purpose office point etc.), it obtains leading to for the illegal of different dimensions
Traffic statistics meter information pool (duration of call dimension, change in location number dimension in the unit time, number of calls dimension in the unit time,
It is called number dimension in unit time, is concurrently called number dimension, response percent of call completed dimension, list in the unit time in the unit time
Caller release rate dimension etc. in the time of position), (calling time in the unit time of various dimensions decision criteria is obtained by decision Tree algorithms
Number dimension is called number dimension, is concurrently called number dimension, caller release rate in the unit time in the unit time in the unit time
Dimension combination).The illegal communication by public telephone statistical information data collection combined according to various dimensions decision criteria is via data mining analysis
Module determines whether the user is doubtful fraudulent user.If the user is doubtful fraudulent user, this number is updated to black name
Single database is simultaneously emitted by corresponding information destination user prompter, it is understood that there may be fraud.
Fig. 4 is the specifically intended of each module in Fig. 3 provided in an embodiment of the present invention, as shown in Figure 4, comprising:
Step 401 --- the associated big data ticket information of bottom will be received, according to user's various dimension (examples of interest
Such as: duration of call dimension, change in location number dimension in the unit time, number of calls dimension in the unit time, in the unit time
Called number dimension is concurrently called number dimension, response percent of call completed dimension, master in the unit time in the unit time in the unit time
It is release rate dimension etc.), illegal communication by public telephone statistical information pond (dimension selected above is obtained via illegal communication by public telephone statistics generation module
Statistical information data collection).
Step 402 --- the decision criteria of various dimensions is obtained by decision Tree algorithms.The model good according to precondition obtains
To the decision criteria of best various dimensions, it is assumed that obtained best dimension are as follows: number of calls dimension in the unit time, in the unit time
Called number dimension is concurrently called number dimension and caller release rate dimension in the unit time in the unit time.
If step 403 --- number to be verified jumps to step 406 in black list database, and triggering is intercepted or reminded
Module.If not jumping to step 404 in black list database.
Step 404 --- the illegal communication by public telephone statistical data collection combined according to various dimensions decision criteria analyzes mould through KNN
Block (KNN by calculate new data between data point different classes of in historical sample data at a distance from classify to new data) sentence
Whether fixed is doubtful fraudulent user.
Wherein, it is as shown in table 1 the illegal communication by public telephone statistical data collection of cell-phone number to be verified, wherein statistical interval may be selected:
Statistics, daily statistics, weekly statistics, monthly statistics etc. per hour.
Table 1: the illegal communication by public telephone statistical data collection table of cell-phone number to be verified
Step 405 --- doubtful fraudulent user processing module receives KNN analysis module and determines result.If it is doubtful fraud
The number is then updated to black list database by user, while triggering interception or reminding module.It is used if not doubtful fraud
Family, then without any processing.
Step 406 --- it is intercepted or is reminded, send corresponding information to called subscriber.
Wherein, data mining algorithm can be KNN (k-NearestNeighbor, K arest neighbors) algorithm, Naive Bayes
(NaiveBayesian classification, naive Bayesian) scheduling algorithm.Oneself of antifraud is described by taking KNN as an example herein
Adaptation process.
The scheme provided according to embodiments of the present invention is obtained by analyzing big data ticket information based on big data analysis
Illegal statistical information pond, according to various dimensions decision criteria, by data mining analysis, N data set before obtaining is final to analyze
Out a possibility that doubtful fraudulent user, the dependence to independent black list database is got rid of, improves the standard for determining swindle number
True rate reduces False Rate and misdetection rate to improve the real-time intercepted to swindle number.
Although describing the invention in detail above, but the invention is not restricted to this, those skilled in the art of the present technique
It can be carry out various modifications with principle according to the present invention.Therefore, all to be modified according to made by the principle of the invention, all it should be understood as
Fall into protection scope of the present invention.
