Electronic invoice data processing method, device and system based on private chain

Abstract

The invention discloses an electronic invoice data processing method, an electronic invoice data processing device and an electronic invoice data processing system based on a private chain. The electronic invoice data processing system comprises an electronic invoice uploading server and a private chain system composed of a plurality of accounting servers, wherein each accounting server in the private chain system is used for recording transaction information and invoice information generated when transaction operation is executed to respective blockchain; and the electronic invoice uploadingserver communicates with each accounting server and is used for transmitting the transaction information and the invoice information stored on the blockchain of each accounting server to an external system. The electronic invoice data processing method, the electronic invoice data processing device and the electronic invoice data processing system can guarantee that the invoice information in theinvoice management system cannot be tampered, generate the transaction information and the invoice information at the same time when the transaction operation is executed, can provide the invoice information for users in real time, and enhance the user experience.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to a private chain-based electronic invoice data processing method, device and system. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] There are many types of banking business, involving multiple business systems, and a large number of transactions that require the issuance of value-added tax invoices. The existing centralized data storage model requires each business system to separate the business transactions that require invoicing from price and tax, and issue them in a unified manner. To the invoice management system (centralization), the invoice management system will issue invoices on demand according to customer needs. [0004] It can be seen that the existing bank invoic...
