Description
Technical field
The present invention relates to a kind of customer data management systems based on block chain.
Background technique
Block chain is the Floor layer Technology of bit coin, most delivers topic by middle acute hearing (Satoshi Nakamoto) early in 2008
It is proposed in paper for " a kind of bit coin: point-to-point electronic cash system ".Block chain is a kind of (non-right based on encryption technology
Claim encryption, hash algorithm), timestamp, common recognition algorithm, the technologies such as P2P network decentralization distributed electronic account book.Earliest,
The it is proposed of block chain is for the digital cash applications such as bit coin, ether mill (next generation's encryption currency and decentralization application platform)
Block chain agreement is extended, with the application of intelligent contract, the other kinds of voucher such as stock, security also be can be expressed as
Digital asset on block chain.Later, the appearance of various block chains community, autonomy organization, company, block chain further expand therewith
Open up the function of intelligent contract, for realizing various businesses logic, and with the technologies such as artificial intelligence, cloud computing, big data, Internet of Things
In conjunction with being further applied to the fields such as governance, medical treatment, education, and also constantly extending using starting to enrich.
Block chain is the novel of the computer technologies such as Distributed Storage, point-to-point transmission, common recognition mechanism, Encryption Algorithm
Application model.It by it is all enter chain information (data block) be combined and to be formed in such a way that sequence is connected sequentially in time
Linked data structure, and guarantee can not distorting, can not forging and can be traced for all information in a manner of cryptography.Based on block
The characteristic of chain can effectively solve the information asymmetry in client information management work, the phases such as leaking data, information are maliciously tampered
Close problem.
As banking is deepened reforms, interest rate marketing is promoted, profit of bank reduced space, and banking is faced with competition more
Add fierceness.More and more banks are completed operation enterprise-level Management System for Clients Information (Enterprise Customer
Information Facility, ECIF) unified management entrance as full row customer information, pass through unified customer ID, concentrate
Each dimensional information of managing customer, on-line real-time the means such as is updated to customer information realizes uniformly depositing for customer information substantially
Storage is updated and is shown.
Currently, the quickening with financial technology process promotes, block chain technology is able to continue to develop and popularize, especially closely
Auspicious wave (Ripple) that phase rises, the two generation block chain technologies such as ether mill (Ethereum), have pushed block chain to the application stage.
Block chain explorative research at this stage is unfolded mainly around financial field.In conjunction with the opening of itself, autonomy, it is traceable,
Information such as can not distort at the characteristics, be applied well in multiple financial fields, such as across mechanism payment clearance, supply chain finance,
Asset securitization, letter of credit etc. are related to the application scenarios participated in many ways and relevant information confidentiality, authenticity are more demanding.
The prior art, to bank client data application, or based on biometrics identification technology, to customer information
Identification judgement is carried out, or is all using customer information of bank system as master data, other systems for participating in mechanism are used as from data
Node periodically carries out the synchronous mode of major-minor notebook data.Data main in such a way that file transmits, is transferred to other copy sections
Point.Data transmission procedure not can guarantee integrality, safety, consistency.Data receiver and data sender generally require fixed
Phase carries out comparing and data difference analysis, investigation analysis abnormal data Producing reason, this artificial investigation mistake of dependence
Mechanism, easily influence the accuracy of data, or even the problems such as cause loss of learning, reveal and be tampered, seriously affect bank
The development of business.
Currently based on the most widely used bit coin of open the Internet block chain, the average trade confirmation time is more than 10 points
Clock, transaction needs the confirmation of tens of thousands of common recognition nodes every time, and the expense traded every time is more than 0.01 dollar, and transaction cost is higher.Cause
It is anonymous for participating in the verifier of common recognition, however not excluded that 51% risk of attacks that some nodes are caused for collusion reason, it is whole to pacify
Quan Xing, timeliness is lower, high expensive.In current financial industry status, each of client information management and information exchange is participated in
Between mechanism, there is preliminary common recognition foundation of trust.
Although the ECIF system of each bank realizes the unified management and displaying to current row customer profile data, because
Effective verification means are lacked to the authenticity of customer information, customer information update need client to handle to site there are hysteresis qualitys etc.
Problem leads to the authenticity, accuracy, the timeliness of update all Shortcomings of customer information, affects based on customer information
Correlation analysis decision.
(1) the ECIF system of bank is related to the various aspects attribute of client, including name, gender, type of credential, certificate number
Code, phone number, address, occupation, income, affiliated person etc..The typing of every terms of information rely primarily on bank's employee's typing with
It checks, automatically means verify the authenticity of information to shortage system, it is difficult to guarantee the accuracy of information；
(2) update of customer information item needs client to send a telegraph site customer service or handle to the site scene of progress, on the one hand believes
Breath ground, which updates, has obvious lag, on the one hand due to caused by (1), can not verify the accuracy and authenticity of information after modification；
(3) customer information is between the cross-systems such as multiple banking systems, inside and external structure, it is also possible to which there are data biographies
Defeated delay and data inconsistency, customer information maintenance cost and verification cost it is larger, often after a period of time, need into
Row full dose compares, and manual analysis, to determine the accurate information of client.One application No. is 201710822611.8 is invented,
It provides the customer information access control method and device of a kind of financial information system, by the value of the access control variable with
The regular matrix is matched, and is obtained access and is determined result, determines that result accesses control according to access.This method mesh
Before be limited only to use inside some banking institution, use scope exist compared with big limitation.It is needed when customer information accesses
Share and access is carried out between bank, operator and government department across multiple organizations, such as information, it just can not be dependent on simple
The access control based on Variable Control, because of the variable and regular matrix that are stored in inside bank, not can guarantee its not by
Distort, other mechanisms be unable to fully trust there are a certain in-house data, therefore not can guarantee critical data accuracy,
Safety and consistency.
(4) be related to the association attributes of customer information, in the case where centrally stored, exist by artificially distorted it is improper to obtain
A possibility that interests.The marketing system of bank, big data analysis engine are often based upon ECIF offer when carrying out customer analysis
Client basic data generates the full side view and correlation marketing program of client in conjunction with the account of bank, product related information, because
For (1), (2) bring inaccuracy and lag, leads to the discrepancy of correlation analysis result, affect that whole marketing is movable to be opened
Exhibition；Application No. is an inventions of 201611051829.X, and it discloses a kind of customer information processing method and system, method packets
It includes and obtains a plurality of customer information from customer information database according to business feature and obtain one or more customer information collection, and
The corresponding pass between customer information and user is established according to default allocation rule from a plurality of user information is obtained in customer data base
System, organizes together client crowd's information of same or similar shopping preferences according to business feature to obtain customer information collection, will
Customer information distributes to the user of acquisition so that customer information flows between users.This patent uses database D BLink's
Mode realizes data transmission and the data processing across data source.There are great hidden danger for the mode of this data transmission, if
Database manipulation level does not take stringent rights management, probably due to the mistake of program code, database occurs irreversible
Data manipulation, data may permanently lose or data modification history can not trace, and there are great risk hidden danger and dangerous
Property, it is unable to satisfy security needs of the financial institution to data.Application No. is an inventions of 201710639755.X, propose
A kind of multi-functional Management System for Clients Information, mainly comprising client's Self management system and manager's management system.Pass through client
Both information management and manager's management system coordinate, the information of common managing customer, realize customer information safety and effectively
Property.But in the design of this patent, manager possesses highest permission, even if without client itself authorization, it can also be to client's
Information is increased, is modified, is deleted.Even if there is log recording for inquiry, retrospect and audit in operation, but still deposit
It is tampered in data, causes business datum that mistake occurs, cause the risk of business economic loss and reputation loss.
(5) critical asset of the customer information as bank, privacy degrees are relatively high, the mode of traditional centralized deployment
Limit the ability shared across inter-agency customer information；
(6) ECIF system generallys use active and standby or cluster mode and externally provides real time service, since it concentrates deployment
Characteristic causes all customer information relationship tradings (increase, delete, changing, looking into) all to need to converge to the system and handled, often there is one
Determine performance bottleneck.
Currently, block chain be mainly used in bank supply chain finance, payment clearance, in terms of, but
It is that the application problem for being solved to share across inter-agency customer information using its advantage is but very studied less, in Management System for Clients Information
On application do not have relevant patent and literature research also.

Information is encrypted, and pertinent customer information can only can be read with private key decryption rear by the information terminal of corresponding mechanism；
Devise the client information management method based on financial union chain, including customer information authenticity verification scheme, with
And user information change management method；
Devise the external service plan of customer information based on financial union chain.
(1) network architecture diagram
As shown in Figure 1, showing that network structure is as follows according to main points as above, financial union chain is related to more participation mechanisms,
Including government department, operator, bank, stock trader etc., the access node of response is assigned with for each mechanism.Each participation mechanism is equal
It can be linked into corresponding node by corresponding terminal.Because being related to customer information privacy, participant further includes supervision department, is based on
The ability of tracing to the source of block chain supervises the service condition of customer information.
Each participates in mechanism and links ingress access financial union chain by the block of distribution.The information system of each mechanism is logical
The communication of the SDK packet and access node that call financial union chain to provide is crossed, and then the cochain and phase of realizing customer information are inside the Pass
That holds increases newly, modification, synchronizes.The operating procedure of all pairs of customer informations will be all recorded on chain, be supervised convenient for regulatory agency
Superintend and direct inspection.
(2) the intelligent account book of customer information and intelligent contract
As shown in Fig. 2, important composition of the intelligent account book as block chain technology, saves uplink data in what manner,
Which kind of carry out checking that modification is arranged with permission.
Client intelligent account book includes client's essential information, customers' credit information, customer account product information, customer information
Source and ownership, the setting of customer information access authority, customer information maintenance priority assignation, customer information service condition etc..Client
Essential information preserves the basic data of client, such as the unified customer ID of full chain, customer name, gender, type of credential, certificate
The basic datas such as number, cell-phone number are the basic status symbols of client.Customers' credit information is mainly to embody the personal sign of client
The credit rating of situation and interested third party mechanism is believed as a result, being the concentrated reflection of the credit situation of client.Customer account produces
Product information is mainly by record client in the assets of the financial institutions such as bank, stock trader, insurance business, debt, the financing of investment, guarantor
The information such as the products such as danger.Customer information source and ownership have recorded the provider and user of pertinent customer information item.Client
Message reference maintenance permission control define pertinent customer information item access maintenance permission, i.e., which participate in mechanism have permission
Access the corresponding customer information item of maintenance.Customer information service condition defines each customer information and increases, deletes, changing, looking into operation need
The content to be recorded is tracked for recording customer information by the service condition of different participation mechanisms convenient for regulatory agency
Management.
Intelligent contract supports multiple technologies programming language to realize, such as java, javaScript, go etc., participant passes through
When SDK carries out customer information relevant operation, SDK has invoked the judgement that intelligent contract correlation function completes logic rules.
Intelligent contract includes the newly-increased service of customer information, customer information safeguard service and customer information Notification of Changes service.
The newly-increased service of customer information, the triggering when new intelligent account book data are written into block chain check corresponding mechanism
Whether there is corresponding customer information item to have corresponding operating right, new intelligent account book data are total to if meeting permission
Know, new intelligent account book data are otherwise set to invalid (data of the more previous item of insertion, to cover)；
Customer information safeguard service, the triggering when new intelligent account book data are written into block chain, checks corresponding mechanism
Whether there is corresponding customer information item to have corresponding operating right, new intelligent account book data are total to if meeting permission
Know, new intelligent account book data are then otherwise set to invalid (data of the more previous item of insertion, to cover)；
Customer information Notification of Changes service, after intelligent account book that is newly-increased or modifying is known together successfully by block chain, triggering
The participation organization information of access organization data Notification of Changes subscription is read in the service, generates corresponding notification information write-in block
In chain, allows the access node of other mechanisms to read and execute simultaneously operating.
(3) client information management permission controls
Based on intelligent contract provided in upper (two), different clients item of information can be set for different participation mechanisms
Set different operating right and access authority.Whether the setting of permission depends primarily on mechanism has authority to related information items
Property, i.e., whether can ensure that the authenticity of related information items content.For example, client certificate type, the information of passport NO., portion of government
Door has authority, therefore there are the modification of relevant information, newly-increased permission in government department, other, which participate in mechanism, access authority；Client
Phone number, operator confirm the service condition of the phone number of client in combination with data, therefore possess relevant maintenance power
Limit, other participants possess access authority.The setting of permission is stored in the rule of intelligent account book, when participant is called to asking
It asks and is verified.
As shown in figure 3, in this example, mechanism dep1 possesses the search access right of all customer informations, electricity in essential information
Talk about the newly-increased and modification authority of field and all customers' credit information, the deletion permission of no customer information.Wherein possess and repairs
The authority for changing the field of permission is 5.When access node receives the association requests of participant, school is carried out in conjunction with priority assignation
It tests.In addition, being directed to, same field is accessed by more mechanisms and more news, system ensure the standard updated using following mechanism
True property.
Each field setting field is locked, and is used to determine whether to be modified, after being updated or safeguarding every time, field adds automatically
Lock, mechanism for locking up have the right voluntarily to unlock the field；
The rank of field lock determines that there is same or higher authoritative mechanism to have the right to unlock by the authority of participation mechanism
Field lock is updated；
When above-mentioned mechanism ensure that more families equally modify authoritative mechanism and modify to a certain field, with final updating
Subject to；It is such as high authoritative because automatic locking meanwhile after a certain field is possessed higher authoritative mechanism and modified
Mechanism does not unlock, and low authoritative mechanism can not be modified again, and the accuracy and authority of field information are also ensured with this.
As shown in figure 4, by newly-increased from customer information and modification is to the customer information changing process for combining financial union chain
Carry out more careful description.It is as follows that pertinent customer information increases process newly:
The access system that the participation mechanism of customer information item need to be increased newly is called by using the SDK that financial union chain provides incites somebody to action
Pertinent customer information item is gone here and there with json and is sent；The encryptions such as SDK wants the data of cochain to be encrypted, and support state is close and international are calculated
Method.
When access node receives related data newly-increased request, the newly-increased service of intelligent account book customer information is triggered, checks Shen
Please mechanism whether have newly-increased permission；
There is no relevant operation permission such as, directly refuses, then refuse to operate, the block chain data being originally written are by initial data
Covering；
If any newly-increased permission, common recognition is initiated.
Each node carries out operation for common recognition request, such as meets Correlation block create-rule, common recognition is reached；
Access node generates block according to feedback, synchronizes with each node, completes information cochain.
When customer information is updated, correlation step increased newly with customer information it is similar, i.e., associated mechanisms call SDK will become
The customer information item cochain of change.Customer information safeguard service in intelligent contract judged for mechanism permission, as mechanism without
Permission safeguards relevant information, directly refuses.If mechanism has permission maintenance relevant information, access node initiates common recognition, reaches common understanding
Afterwards, block is generated, cochain is recorded and is synchronized to all nodes on chain.Rear related information items are synchronously completed to complete to update.
When participation mechanism needs inquiring customer information, by calling the interface of correlation SDK encapsulation, intelligent account book is read
Access authority.Access node judges access node, according to the search access right rule formulated in intelligent account book if there is phase
Access authority is closed, pertinent customer information is read from chain, feeds back to request mechanism, completes inquiry；Simultaneously to the inquiry trade into
Row record, including initiate mechanism, inquiry content, return the result, by chained record in the transaction, card is deposited as transaction, convenient for subsequent
Supervision is had access to.
(4) customer information with participate in mechanism from systematic synchronization mechanism
As shown in figure 5, for the normal development that guarantee section participates in the peculiar business of mechanism, it is each to participate in mechanism optionally
Locally retain the copy of pertinent customer information at it.In order to guarantee the consistency of data on local data and chain, devise as follows
Synchronization mechanism.
The system that participation mechanism is docked with access node has subscribed it with access authority by the way of distribution subscription
The notice of customer information change；
After the newly-increased or update that access node receives customer information on chain is known together successfully, the client of intelligent contract is triggered
Information change notifying service, read the access mechanism subscription participation organization information, generate notify and save into block chain by
The participation node for participating in mechanism, which is read out, obtains sending out notice information；
After the system for participating in mechanism receives notice, pertinent customer information is inquired, query result is updated to this
In ground customer information copy.
(5) it is engaged in based on financial union chain to customer service
Management System for Clients Information based on financial union chain to all access mechanisms provide relevant inquiring in its permission,
Safeguard service specifically includes that
The mechanism inquiry pertinent customer information item for having access authority is supported, as bank's access client's essential information, account produce
Product information etc.；
The facility maintenance pertinent customer information item for having maintenance permission is supported, as operator safeguards Client handset number, government
Department safeguards client certificate number etc.；
Refusal participates in mechanism and executes the service of its lack of competence operation and record to operation；
Refuse the access of non-participating mechanism.If alliance's chain is not added for certain enterprise, view accesses chain by its own system
Upper data, associated access node access direct rejection.
In addition, unlike concentrating deployment central access from tradition, the Management System for Clients Information based on financial union chain
Because customer information the whole network is shared, each access node has a complete customer profile data, thus support to participate in mechanism into
Row relevant inquiring, safeguard service.Each mechanism that participates in can access section according to conditions flexible choices such as own service feature, affiliated regions
Point increases the efficiency of inquiry.
