Electronic invoice full life cycle supervision system and method based on an alliance chain

Abstract

The invention provides an electronic invoice full life cycle supervision system and method based on an alliance chain. The system comprises a distributed alliance chain grid jointly constructed by anelectronic invoice platform, a tax bureau and a plurality of electronic invoice dry parties as nodes, and further comprises an invoice information encryption module and a distributed storage module which are connected with the distributed alliance chain grid. The electronic invoice platform is also connected with an out-of-chain electronic invoice dry system party outside the distributed alliancechain network grid; and the cloud server is used for performing interface security authentication and chaining processing on the out-of-chain electronic invoice dry party, uploading the out-of-chain electronic invoice dry party to the distributed alliance chain grid so as to trigger the intelligent contract, and sequentially performing encryption and distributed storage by the invoice informationencryption module and the distributed storage module. According to the system, the full-life-cycle management effect of the electronic invoice is improved, the electronic invoice platform serves as athird-party platform agent to be online, credibility, safety and traceability of electronic invoice information are guaranteed, and meanwhile the enterprise and personal time cost is reduced from different scenes.

Description

technical field [0001] The invention relates to the technical field of invoice information management, in particular to a system and method for monitoring the entire life cycle of electronic invoices based on alliance chains. Background technique [0002] Since the implementation of relevant policies on electronic invoices nationwide, it has effectively solved the problem of invoicing in some industries that require invoices in most sectors after the reform of business tax.

Problems solved by technology

[0004] The present invention aims at the fact that the electronic invoice information is untrue due to artificial changes in the prior art, and that it is impossible to prevent false invoices issued on the market and the key stages of electronic invoice business work are mostly carried out through different platform systems. Dealing with problems such as poor linkage between each other provides a full life cycle supervision system for electronic invoices based on the alliance chain. The system is simple in design, optimized in structure, and skillfully introduces blockchain alliance technology and data encryption technology to improve The whole life cycle management effect of electronic invoices has been achieved, and the electronic invoice platform acts as a third-party platform agent to upload to the chain. While ensuring the credible, safe and traceable information of electronic invoices, it can reduce the time cost and energy cost of enterprises and individuals from different scenarios
