Electronic invoice management system and method based on distributed accounting

Abstract

The invention discloses an electronic invoice management system and a method based on distributed accounting. The system comprises multiple verification nodes. Each verification node comprises an electronic invoice contract module and an agreement module, wherein the electronic invoice contract module comprises an electronic invoice service intelligent contract and is configured to be used for receiving a transaction command of the electronic invoice service intelligent contract and executing the transaction command according to a result of the agreement module so as to establish a block and form a block link, and the electronic invoice service intelligent contract is operation performed on an electronic invoice. The agreement module is configured to be used for communicating with other verification nodes when being triggered and making an agreement on a transaction command sequence between all verification nodes for the received transaction command according to an agreement algorithm. According to the invention, tamper-proofing is realized and the system and the method are cost-effective.

Description

technical field [0001] The present invention relates to the technical field of electronic invoices, and more specifically relates to an electronic invoice management system and method based on distributed bookkeeping. Background technique [0002] Electronic invoices are business vouchers issued and received by all units and individuals in purchasing and selling commodities, providing or receiving services, and engaging in other production and business activities. Since January 1, 2016, the State Administration of Taxation has officially launched the use of the VAT electronic invoice system to issue VAT electronic invoices and allow them to be used as reimbursement vouchers. Nowadays, more and more e-commerce companies, restaurants, etc. are using the value-added tax electronic invoice system to provide consumers with electronic invoices. However, since electronic invoices are digital assets, they are naturally easy to lose, easy to copy, and easy to tamper with. For elect...

Problems solved by technology

[0003] For the existing VAT electronic invoice system, first of all, because the security of electronic invoice information mainly depends on the technical level of the VAT electronic invoice system and electronic invoice information database itself and its operation and maintenance personnel, the data itself is not invulnerable. This will cause great security risks in the existing VAT electronic invoice system and increase the cost of system development and maintenance

Secondly, due to the need to verify the authenticity of electronic invoices to a trusted central agency or issuer, this will not only pose a great test to the technical level and personnel quality of the central agency, but also bring a lot of communication overhead and network bandwidth occupation , which increases system complexity and operating costs

Furthermore, each participant in the electronic invoice business has its own database of electronic invoice information and is maintained by itself, that is, the electronic invoice information is stored in a decentralized manner. This decentralized storage makes it difficult for the electronic invoice information to be tampered or destroyed recover

In addition, due to the different types of databases and the heterogeneity of storage media, it is technically difficult to implement a unified data synchronization mechanism among these databases.
