Bank invoice data processing method and system based on block chain

Abstract

The invention provides a processing method and system for bank invoice data based on a block chain, and relates to the technical field of block chain and financial data processing, and the method comprises the steps: setting an invoicing limitation parameter corresponding to a tax number of a bank institution and an expense identification of a bank invoice; when an invoicing request is obtained, analyzing the invoicing request to obtain invoicing transaction data, an invoicing bank institution tax number and an invoicing processing mode; splitting or combining invoicing transaction data according to the invoicing processing mode, an invoicing limit parameter corresponding to a tax number of an invoicing bank institution and an expense identification of a bank invoice; invoicing according to the split or combined invoicing transaction data to obtain an invoicing result, and associating the invoicing result with the invoicing transaction data; and uploading the invoicing limit parameter corresponding to the tax number of the current invoicing bank institution, the expense identification, the split or combined processing record, the invoicing result and the associated relationship to a block chain.

Description

technical field [0001] The invention relates to the technical field of blockchain and financial data processing, in particular to a method and system for processing bank invoice data based on blockchain. Background technique [0002] There are a large number of institutions in the banking system, and there are complex hierarchical relationships among the institutions. Each institution corresponds to its own tax ID number, and the invoice limit for invoicing transactions corresponding to each institution's tax ID number is different. When invoicing a customer, the customer will choose the transaction that needs to be invoiced, and the transaction may be split and invoiced, or the transaction must be split if it exceeds the limit of a single invoice. Whether the split invoice data is within a reasonable range, or whether the customer Multiple transactions are required to issue one invoice. Once there is a failure in the invoicing process, the transactions involved will be froz...

[0002] There are a large number of institutions in the banking system, and there are complex hierarchical relationships among the institutions. Each institution corresponds to its own tax ID number, and the invoice limit for invoicing transactions corresponding to each institution's tax ID number is different. When invoicing a customer, the customer will choose the transaction that needs to be invoiced, and the transaction may be split and invoiced, or the transaction must be split if it exceeds the limit of a single invoice. Whether the split invoice data is within a reasonable range, or whether the customer Multiple transactions are required to issue an invoice. Once there is a failure in the invoicing process, the transactions involved will be frozen and require subsequent complicated unfreezing processing, resulting in cumbersome invoicing process and poor customer experience.
