Electronic invoice verification method, system, storage medium, computer equipment and terminal

Abstract

The invention belongs to the technical field of communication network safety, and discloses an electronic invoice verification method, a system, a storage medium, computer equipment and a terminal. The method comprises an electronic invoice checking system initialization stage; a system user registration stage; an invoice generation stage of multi-party verification; an invoice disclosure checkingstage; and an invoice transaction information with authority control checking stage. According to the invention, by designing a joint signature scheme, the dual verification signature of a tax administration department and an invoicing party can be realized. An inspector only needs to verify the signature once to complete invoice authenticity verification, so that the safety, convenience and calculation efficiency of invoice authenticity verification are improved; the transaction information in the invoice is encrypted and protected, and privacy information of two transaction parties is prevented from being leaked; a general electronic invoice checking framework based on a certificateless digital signature scheme is constructed, safety and management problems caused by secret key trusteeship are avoided, invoice layout file data are simplified to facilitate storage and transmission, various protocol attacks can be resisted, and paperless application of electronic invoices is supported.

Description

technical field [0001] The invention belongs to the technical field of communication network security, and in particular relates to an electronic invoice verification method, system, storage medium, computer equipment and terminal. Background technique [0002] At present: With the rapid development of e-commerce, my country's network / mobile payment transactions have increased sharply. Invoices are used as information certificate carriers for consumer payments. Under the growing trend of network payment coverage, traditional paper invoices urgently need to be fully electronic. Electronic invoices have the advantages of paperless, easy storage / transfer / delivery, and low consumption. However, due to the loss of physical anti-counterfeiting features of electronic invoice documents, it also brings many security challenges to invoice anti-counterfeiting and inspection operations. Paper invoices can be anti-counterfeited through a special manufacturing process, and at the same tim...

AI Technical Summary

Problems solved by technology

In the existing verification scheme based on electronic signature, the tax authorities only sign the invoice template, but do not verify the invoice transaction information, which may cause problems such as invoice data falsification

In addition, the transmission security protection of the invoice transaction information is not considered, which will easily lead to the privacy leakage of both parties

The two-dimensional barcode anti-counterfeiting method is based on the two-dimensional code (GM, grid matrix code) technology with independent intellectual property rights in my country, which can encrypt and encode the invoice element information, and has the advantages of large storage capacity and high anti-counterfeiting efficiency, but the two-dimensional code inspection method requires hardware requirements High, it needs a mobile phone camera or a special inspection machine to scan and compare the invoice with the tax system database. The inspection process is complicated and it is difficult to realize the anti-counterfeiting inspection of full face information

[0006] The difficulty of solving the above problems and defects is: the current mainstream electronic invoice inspection system mainly adopts the method of online element comparison, which is inefficient and has high requirements for the network environment

However, the anti-counterfeiting and inspection scheme based on electronic signatures does not take into account the security requirements of the tax authorities and the billing party for both verification and transaction information privacy protection, and the structure is simple and the calculation consumption is high.

Due to the high calculation consumption of the public key algorithm, the multi-party verification signature in the current scheme requires multiple signature verifications, which seriously reduces the verification efficiency, and leads to a complex storage structure of the electronic invoice file, which is not conducive to transmission and storage
