Customer data management system based on block chain

Abstract

The invention provides a customer data management system based on a block chain. Participants are connected to a financial union chain through a corresponding block link-in node, so as to realize theuplink of customer data, and realize the inquiry, addition, modification and synchronization of customer data according to the customer intelligent account book and the customer intelligent contract.The financial union chain designs a sectional protection lock for the customer data on the chain to realize the circulation of the customer data among the set participants; The client intelligent account book comprises a client information access authority, a newly added authority and a client information maintenance authority, wherein the client intelligent account book comprises a client information access authority, a client information access authority and a client information maintenance authority. Customer Intelligence Contract includes Customer Information Addition Service, Customer Information Maintenance Service and Customer Information Change Notification Service. The invention realizes the non-tampering, encrypted storage and privilege access of the uplink information, which canensure the privacy of the customer information and realize the cross-organization sharing of the public basic customer information on demand, such as the mobile phone number is shared between the operator and the government department, and between the operator and the bank.

Description

technical field [0001] The invention relates to a customer data management system based on blockchain. Background technique [0002] Blockchain is the underlying technology of Bitcoin, which was first proposed in 2008 by Satoshi Nakamoto in a paper entitled "Bitcoin: A Peer-to-Peer Electronic Cash System". Blockchain is a decentralized distributed electronic ledger based on encryption technology (asymmetric encryption, Hash algorithm), time stamp, consensus algorithm, P2P network and other technologies. At the earliest, the blockchain was proposed to be used for digital currency applications such as Bitcoin. Ethereum (the next-generation cryptocurrency and decentralized application platform) expanded the blockchain protocol. With the application of smart contracts, stocks, securities and other Types of credentials can also be expressed as digital assets on the blockchain. After that, with the emergence of various blockchain communities, autonomous organizations, and compan...

AI Technical Summary

Problems solved by technology

The entry of various information mainly depends on the entry and inspection of bank employees, lack of systematic and automatic means to verify the authenticity of the information, and it is difficult to guarantee the accuracy of the information;

[0010] (2) The update of customer information items requires the customer to call the outlet customer service or go to the outlet for on-site processing. On the one hand, there is an obvious lag in updating the information, and on the other hand, due to (1), the accuracy and authenticity of the revised information cannot be verified. ;

[0011] (3) Customer information may be delayed in data transmission and data inconsistency between multiple banking systems, internal and external structures, etc., and the cost of customer information maintenance and verification is relatively high. Often after a period of time, it is necessary to carry out Full comparison and manual analysis to determine the accurate information of customers

When customer information access needs to be shared across multiple organizations, such as information shared among banks, operators and government departments, it is impossible to rely on simple variable-based access control, because the variables and rule matrices stored in the bank , it cannot be guaranteed that it will not be tampered with, and other institutions cannot fully trust the data stored in a certain institution, so the accuracy, security and consistency of key data cannot be guaranteed

[0012] (4) In the case of centralized storage, relevant attributes involving customer information may be artificially tampered with to obtain improper benefits

However, in the design of this patent, the administrator has the highest authority, and can add, modify, and delete customer information even without the authorization of the customer himself.

Even if there are log records available for query, traceability and audit during the operation process, there are still risks of data tampering, resulting in errors in business data, and causing economic losses and reputation losses to the enterprise

[0013] (5) As an important asset of the bank, customer information has a relatively high degree of confidentiality, and the traditional centralized deployment model limits the ability to share customer information across institutions;

[0014] (6) The ECIF system usually provides real-time services externally in the form of active / standby or cluster. Due to its centralized deployment, all customer information-related transactions (addition, deletion, modification, and query) need to be aggregated to the system for processing, often There is a certain performance bottleneck

[0015] At present, blockchain is mainly used in supply chain finance, payment settlement, asset securitization, etc. in banks, but the use of its advantages to solve the application problem of cross-institutional customer information sharing has rarely been studied. In the customer information management system There are no related patents and literature research on the application of
