This dispersion and fragmentation pose challenges for enterprises in financial analysis and decision-making;

[0003] How to construct a financial data sharing control chain, share financial data through the constructed financial data sharing control chain, improve the security of financial data during the sharing process, and prevent unauthorized access by financial data sharing personnel is a problem we need to solve. For this purpose, a method and system for sharing financial data based on big data are provided herein. Summary of the Invention

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a method and system for sharing financial data based on big data.

[0005] The first object of the present invention is to develop a method for sharing financial data based on big data.

[0006] The second object of the present invention is to develop a system for sharing financial data based on big data.

[0007] To achieve the first object of the present invention, the present invention is realized through the following technical solutions: A method for sharing financial data based on big data, comprising the following steps:

[0008] Step S1: Construct a financial data sharing control chain;

[0009] Step S2: The financial data sharing personnel input financial data into the financial data input node in the constructed financial data sharing control chain, and the input financial data is verified through the financial data sharing control chain;

[0010] Step S3: The financial data sharing control chain generates an authentication code according to the verification result and classifies the verified financial data;

[0011] Step S4: Store the classified financial data through the financial data sharing control chain;

[0012] Step S5: The financial data sharing personnel input the basic information into the financial data sharing node in the constructed financial data sharing control chain, and obtain the access privilege level of the financial data sharing personnel according to the input basic information;

[0013] Step S6: Obtain the corresponding financial data stored in the financial data sharing control chain according to the access privilege level of the financial data sharing personnel obtained.

[0014] Furthermore, the process of constructing the financial data sharing control chain includes:

[0015] The financial data sharing control chain is composed of a financial data input node, a financial data verification node, a financial data level division node, a financial data storage node, an access privilege level division node, and a financial data sharing node;

[0034] Associate the classified financial data with the corresponding authentication code;

[0035] Store the financial data and the authentication code associated with the financial data in the corresponding storage area according to the level of the financial data.

[0036] Further, the process of obtaining the access permission level of the financial data sharing personnel according to the input basic information includes:

[0037] The financial data sharing node sends the basic information input by the financial data sharing personnel to the access permission level classification node. The access permission level classification node generates an authentication code according to the basic information input by the financial data sharing personnel, sends the generated authentication code to the financial data storage node, and the financial data storage node receives the authentication code sent by the access permission level classification node and compares the received authentication code with the stored authentication code;

[0038] If there is no stored authentication code that is the same as the received authentication code, the financial data sharing personnel are prohibited from accessing the financial data sharing control chain;

[0039] If there is a stored authentication code that is the same as the received authentication code, obtain the level of the financial data associated with this authentication code, and send the obtained level of the financial data to the access permission level classification node;

[0043] Further, the process of obtaining the corresponding financial data stored in the financial data sharing control chain according to the obtained access permission level of the financial data sharing personnel includes:

[0044] The access permission level classification node sends the access permission level of the financial data sharing personnel to the financial data storage node. If the access permission level of the financial data sharing personnel is the first access permission level, send the financial data of the first level stored in the financial data storage repository to the access permission level classification node;

[0045] If the access permission level of the financial data sharing personnel is the second access permission level, the financial data of the second level stored in the financial data repository is sent to the access permission level division node;

[0046] If the access permission level of the financial data sharing personnel is the third access permission level, the financial data of the third level stored in the financial data repository is sent to the access permission level division node;
