Easy data, reputation data, illegal data etc..The mode of data acquisition also has many kinds, and main mode is empty to network
Between these objects carry out reptile, filter out effective data and arranged.Certainly, data acquisition also includes data exchange and net
People's report data etc..
It is characterized in obtaining data from traditional data source channel, the system of filtering out can stablize the data inputting of identification
System, and deep processing processing is carried out to data, handled while carrying out certain classification to data.
2）Typing rule storehouse, prestige record storehouse, information bank, testing result storehouse of the data of storage etc..Data storage and dimension
Shield is also an important ring in anti-fake system, and the source of anti-fraud data often compares many, and data interaction is frequent.Number
According to reliability and it is maintainable often finally determine anti-fake system whether the operation that can stablize.
It is characterized in building high in the clouds data storage, selectes suitable database and the data of collection are stored.Tables of data
Then it is designed according to the type of data, and the database in high in the clouds is optimized, it is ensured that the stable operation of database.
3）Fraud detection is the kernel subsystems of anti-fake system.Fraud detection content scores including prestige, rule detection,
Fraud storage etc..The system mainly includes regulation engine and prestige rating engine.Detecting result data can timely and effectively be sent out
Existing fraud information, it is convenient to make corresponding processing for fraud as early as possible.The process of fraud detection is actually that data are dug
The process of pick, data mining is the fusion of many technologies, and the technology being related to has statistical inference, machine learning, visualization, parallel processing
Deng.
It is characterized in, according to the analysis and arrangement to cheating data, forming a set of relatively effective rule base.In combination with number
According to many algorithms of excavation, automatic business processing is carried out to existing gathered data, and then detect authentic and valid information.
4）System administration is mainly responsible for ensureing the stable operation of whole system, it can to the parameter of each subsystem engine and

Above-mentioned technical scheme is as relatively more traditional anti-fraud model, and each subsystem division of labor is clear and definite, finally by risk pipe
Reason personnel carry out management and control to whole system, reach and control risk, the purpose of combat fraud behavior.However, being applied in actual
Cheng Zhong, can have some limitations, and cause system particularly efficient not run.It is primarily present following problem：
1）Although the sources coverage rate of the gathered data of the system is wider, the reliability of data is not ensured that, it is whole
Individual model be all built upon data source it is true and reliable on the basis of.So during gathered data, need to put into a large amount of
Be operated in the examination to gathered data.While the reliability in order to ensure system, for indefinite data of originating, can be adopted
The attitude that comparison is careful is taken, this large amount of data cannot play due effect.
2）The system takes data centralization to store, because data volume may be huger, can use distributed storage
Mode.But according to CAP（Consistency、Availability、Partition tolerance）Theorem, the one of data
Cause property, availability and subregion fault-tolerance can not be met simultaneously in any distributed system.To existing data, due to planting
Potential O＆M risk is planted, the missing of data is likely to result in, maliciously distorts, so will also result in the result reliability of system
Reduction.
3）During fraud detection, the subjective factor of regulation engine is excessive, may directly affect the processing of fraud information
Resultant error is excessive.
4）The stability of system places one's entire reliance upon effective management to whole system, and there is also potential risk.When system not
Can stable operation when, it is impossible to the data in event interval are effectively managed, the promptnesses of data, validity all without
Method is guaranteed.
The content of the invention

Fig. 2 is public key management flow chart in present system management subsystem.
Embodiment
The present invention is described in further details with specific embodiment below in conjunction with the accompanying drawings.In order to avoid conventional solution
In risk and defect that may be present, the system optimizes from each subsystem of the following aspects, builds a set of new counter take advantage of
Cheat solution.Shown in schematic diagram Fig. 1 of the program：
First, the data acquisition unit for going trustization is built.The collector does not limit submission data object, and the collection of data is not limited yet
Object（It can be Added User with seamless）.System carries out automatic detection first to the data of submission, and preliminary screening is carried out to data.
Data submit object to include individual consumer or qualified unit user, and each data are submitted except preliminary screening, in addition it is also necessary to its
The confirmation of his at least three users.Each user also has a public key and private key, for the encryption to data, it is ensured that the data exist
The safety in limited range before into final shared fraud platform.With for data submission side obtains data examination ＆ verification official
Examination ＆ verification side is given to Data Encryption Transmission after the public key of side, examination ＆ verification side is audited by the private key ciphertext data of oneself.Each data
Submit ID（Including submitting data user and examination ＆ verification data user）Bound with the data of submission.After data submission not
Data can be modified by anyone, only data submitter can submit revocation apply, need also exist for other at least three
The confirmation of user, can be marked after confirming successfully to the ID of this submission（And it is non-delete）.Revocation be also by data more
Newly arrive the effect reached, this data before can guarantee that submits record to still have, and the data of submission can be traced.Therefore the data
The data of shared data platform are irreversible in gatherer process.So it is possible to prevente effectively from may in when multiparty data is shared
The regular disunity of the processing data of appearance, the problem of standard is inconsistent.
Thus data acquisition subsystem scheme is described as follows：The data acquisition unit for going trustization is built, the collector is not
Limit submits data object and data acquisition target；Data to submission first carry out preliminary screening, then through at least three users really
Recognize；Data are encrypted, and submit the ID for auditing user according to user and data to be bound with the data submitted number；Data
Do not receive anyone after submission to be modified data, only receive the revocation application of data submitter submission；Revocation application is through extremely
After few three users confirm, to applying for that the ID of submitter is marked.
Then, the data storage that collective safeguards is built.The shared side of fraud data safeguards a set of database jointly（It is shared
Primary database）.The data are by user（The data submitter of shared data platform and auditor）In each leisure server of oneself
A set of database is stored, the data of each user are full dose data, and the node each submitted records ID and relevant information.
Utilize block chain technology, it is ensured that the data of each node can not be changed.Due to inherently one decentralization of block chain
Database a, side of any data storage stores whole data, so that either party is impossible to folk prescription change number
According to storehouse, so block chain technology can ensure that the data of each node can not be changed.The data in primary database are carried out simultaneously
Encryption：Primary database encryption refers to the data encryption into primary database, and the data encryption of this part is independent, mainly pin
To using data side, it is each in a set of database of local maintenance, and because each side all stores portion, therefore either party can not
Energy altered data is submitted to real master library, meanwhile, it is synchronized after newest data, the secret key pair master data of oneself can be used
The part that storehouse has permission is decrypted, and with reference to the plug-in unit of cloud platform, carries out the utilization of fraud data.So the data of primary database
All it is by encryption, although each with storing a data per family, but shared data can not be directly viewable.Multi-user
Data storage be intended merely to ensure data uniformity and reliability, can not only reach anti-tamper purpose, it is thus also avoided that
Traditional data are because the data disaster that the multinode problem of single node or finite region is brought.
Thus data storage subsystem scheme is described as follows：The data storage that collective safeguards is built, by fraud data
Shared side safeguards a set of primary database jointly；And submit user and data to audit in each comfortable server of oneself of user by data
The a set of database for including total data of storage；The data for ensureing each node using block chain technology can not be changed；To master
Data in database are encrypted, it is to avoid each user is directly viewable to shared data；
Then, constructing system is managed, that is, builds a shared web platform.The subsystem is used to open the shared of data, for connecing
By with management data management basis API（Application Programming Interface application programming interfaces）Connect
Mouth, plug-in unit and client public key etc..Only confirm by multiple keepers, can be just updated to when the system version of next time updates
In system.Meanwhile, also receive the plug-in unit of user's submission, as a shared platform, user can be with integrated plug-in unit to user's sheet
Ground carries out further automatic business processing to the result data inquired.Because plug-in unit is all the handling implement of automation, for
Be exactly the data of primary database and measure what body made, locally only need to these integrated instruments, obtain the reality for oneself wanting to obtain
When form or data results.The system is additionally operable to manage the public key of each user, and user can submit the public key of oneself
Other users are shared to high in the clouds management system, data submitter can extract arbitrary user in the high in the clouds（Examination ＆ verification side）Public key
Carry out data encryption（Asymmetric encryption）, then the data after encryption with P2P（Peer-to-peer, it is point-to-point）Form hair
Audited to examination ＆ verification side, examination ＆ verification side can be to carrying out corresponding review operations after data deciphering.Its schematic diagram such as Fig. 2 institutes
Show.
Thus system management subsystem scheme is described as follows：The shared web platforms of constructing system management, open data sharing,
Receive and the basic api interface of management data management；Receive the plug-in unit of user's submission, it is allowed to which the integrated plug-in unit of user is local to user
Further automatic business processing is carried out to the result data inquired；Manage the public key of user：Each user submits the public key of oneself
Other users are shared to high in the clouds management platform；Data submit user, and management platform extracts arbitrary data examination ＆ verification user's beyond the clouds
Public key carry out data encryption, then the data after encryption issued in the form of P2P data examination ＆ verification user audited, data audit
User is to carrying out corresponding review operations after data deciphering.
Again, automation rule engine and rating engine based on proportional system are built.The engine is also classified into system engine
And engine user, it so can greatly avoid the regular disunity problem of shared data each side.System engine need to be to system pipes
Platform submits operation API, waits version updating to be integrated into the automatically processing of system, these processing can only be limited and tight
Lattice, the rule that can be reached common understanding with more integrated shared each side., can also be with and engine user then needs user oneself to develop
The form of plug-in unit shares to system administration web platforms, is used for shared each side.
Thus engine builds subsystem scheme and is described as follows：Constructing system engine and engine user；System engine is to system
The shared web platforms of management submit operation API, wait version updating to be integrated into the automatically processing of system；Engine user is by wanting
User oneself develops, or shares to the shared web platforms of system administration in the form of plug-in unit, is used for shared each side.
Finally, build and safely and effectively monitor form.The subsystem be also required to web platforms submit inquiry api interface or
Form plug-in unit, and these api interfaces are only needed in local runtime, and platform only serves the effect of shared instrument.User can root
According to the demand of itself, these plug-in units of web platforms to local.It so can quickly go out form, each side also can profit
Developed with respective favourable resource set, reach the effect that resource maximum is utilized.
Thus monitoring Report Subsystem scheme is described as follows：Structure safely and effectively monitors form, and common to system administration
Enjoy web platforms and submit inquiry api interface or form plug-in unit；User is according to self-demand, by above-mentioned plug-in unit to locally.
Because the data of primary database are encryption data, therefore only possess effective（The limited time limit）Account and key
User can be inquired about using above subsystem, and taken appropriate measures for anti-fraud.And other users
It is secondary role, primarily serves the effect of supervision and the safeguards system operation of system.They can share（Submit）Data, but simultaneously
Without using data.Sum it up, can so reach the effect of role's segmentation, different roles are provided as needed.Submit
Data be also the later stage it is traceable, if there is not conforming to rule data or abnormal data, in order to be sufficiently accurate it may be desired to data submission side " revocation "（It is actual
To submit a record again）Data.AC module provides function by the web platforms of system administration, can also be amounted to certainly not being inconsistent
User as defined in platform base is enjoyed to reject（Cancel ID validity）.
