[0006] To achieve the above object, a first aspect of the present invention provides an intelligent financial bill management platform based on blockchain, including: a data acquisition module, an intelligent management module, a data security module, and a user interface module;

[0007] The data acquisition module: regularly obtains the financial data of several projects of an enterprise;

[0008] The intelligent management module: obtains a preset financial data classification table, and classifies the financial data according to the financial data classification table to obtain several groups of financial data;

[0009] Obtains the actual fund data, and judges whether it is necessary to correct the financial data according to the actual fund data; if so, corrects the financial data; if not, retains the corresponding financial data and continuously detects the financial data; integrates the retained and corrected financial data into a financial bill;

[0010] The data security module; constructs a financial sub-chain according to the financial bill, and judges whether the financial sub-chain can be added to the financial bill blockchain; if so, adds the financial sub-chain to the financial bill blockchain; if not, continuously judges the financial sub-chain; and,

[0011] Obtains the user information, determines the user level according to the user information, and judges whether to allow the user to access according to the user level; if so, allows the user to access the financial bill; if not, generates an alarm signal and blocks the user from accessing the financial bill.

[0012] Preferably, the platform further includes a user interface module,

[0013] which is used to provide financial data and corresponding financial bills to the enterprise.

[0014] The present invention makes complex financial data intuitive and easy to understand through the user interface module, displays financial data in forms such as charts, tables, and dashboards, and users can quickly understand key indicators such as revenue, expenditure, profit, etc. of financial data without having to read long reports in depth.

[0015] Preferably, the classifying the financial data according to the financial data classification table to obtain several groups of financial data includes:

[0016] Retrieve the preset financial data classification table, extract financial data, and analyze the financial data to obtain the amount types. Among them, the amount types include income and expenditure.

[0017] Match the financial data with the financial data classification table according to the amount type to obtain the type of the financial data, and integrate the financial data with the same type to obtain several groups of financial data.

[0018] With the preset financial data classification table as the benchmark, the present invention can ensure more accurate and consistent classification of financial data, help reduce human errors, and improve data quality. Classify the financial data according to the amount type and further match it to the specific financial data classification table to display the data more clearly.

[0019] Preferably, the judging whether it is necessary to correct the financial data according to the actual fund data includes:

[0020] Retrieve the actual fund data, number the actual fund data in chronological order, and match the financial data with the actual fund data to obtain the financial data number.

[0021] Judge whether the numbers of the financial data are consecutive. If so, analyze the amounts of the financial data. If not, it is determined that the financial data needs to be corrected.

[0022] Judge whether the amounts of the financial data with the same number are consistent with the actual fund data. If so, it is determined that the financial data does not need to be corrected. If not, it is determined that the financial data needs to be corrected.

[0026] Connect several blocks through the hash values to form a chain structure, and mark the chain structure as the financial sub-chain.

[0027] The present invention divides financial bills into several blocks and determines the nodes for financial bill management. The decentralized feature of this blockchain means that data is not stored on a single server but distributed among multiple nodes in the network. This distributed storage method improves the reliability of data, and even if some nodes fail, the data will not be lost, and it also enhances the security of the system. At the same time, since each block on the blockchain contains the hash value of the previous block, it is conducive to quickly tracing the source and change history of the data, and can quickly locate the problems of financial data and find out the reasons.

[0028] Preferably, determining whether the financial sub-chain can be added to the financial bill blockchain includes:

[0029] Obtaining the consensus mechanism of the financial bill blockchain and retrieving the financial sub-chain; determining whether the financial sub-chain conforms to the consensus mechanism. If it does, it is determined that the financial sub-chain can be added to the financial bill blockchain; if not, it is determined that the financial sub-chain cannot be added to the financial bill blockchain.

[0030] The present invention enables the nodes in the blockchain network to reach an agreement on the legality of the blocks through the consensus mechanism, thereby preventing data from being tampered with or forged. At the same time, in financial bill management, ensuring the accuracy and consistency of data is crucial. By implementing the consensus mechanism, it can be ensured that each financial sub-chain has undergone strict verification and confirmation before being added to the main chain, thus guaranteeing the authenticity and reliability of the financial data on the entire blockchain.

[0031] Preferably, determining whether to allow a user to access according to the user's level includes:

[0032] Retrieving the user's level and obtaining the user's access request; determining the minimum level of users allowed to pass through the access according to the access request;

[0033] Determining whether the user's level is higher than the minimum level. If it is, it is determined that the user is allowed to access; if not, it is determined that the user is not allowed to access.

[0034] The present invention can ensure that sensitive or important resources are not accessed by unauthorized users by setting different levels of users and their corresponding access permissions. This access control mechanism based on levels is an important guarantee for security. By determining whether the user's level meets the minimum level requirements for the access request, it can effectively prevent unauthorized users from accessing restricted resources, thereby protecting the security of the system.
