An invoice verification system based on cloud computing and encrypted two-dimensional code

Abstract

The invention discloses an invoice true check system based on cloud computing and encrypted two-dimensional codes and belongs to a tax invoice true check system. The invoice true check system comprises a tax office cloud computing platform, an encrypted two-dimensional code device and an invoice scanning decrypting device. The tax office cloud computing platform is used for managing the encrypted two-dimensional code device and the invoice scanning decrypting device. The encrypted two-dimensional code device is used for printing the encrypted two-dimensional codes on physical invoices when invoicing invoices for drawers. The invoice scanning decrypting device is used for scanning, decrypting and comparing the invoices needing true check and outputting processing results according to grades to serve as true check basis. Compared with the prior art, the invoice true check system based on cloud computing and the encrypted two-dimensional codes can solve the problems of trust issue and data safety of the existing invoice true check results, and restrains invoice counterfeiting and false invoice using to a certain extent.

Description

technical field [0001] The invention relates to a tax invoice authenticity verification system, in particular to an invoice verification system based on cloud computing and encrypted two-dimensional codes, and can also be used to verify the authenticity of other similar tax invoices. Background technique [0002] As an important part of my country's financial system, invoices are not only an important original document for accounting, but also the main effective means for tax authorities to collect tax calculations and tax audits. At present, there are certain limitations in the existing main invoice authenticity identification methods in my country, which are mainly reflected in: [0003] One: physical anti-counterfeiting and chemical anti-counterfeiting [0004] This anti-counterfeiting technology is to use special paper or special anti-counterfeiting ink to print and supervise invoices during the printing process of invoices. It has relatively low technical requirements....

AI Technical Summary

Problems solved by technology

However, since the methods for generating QR codes are all based on publicly available general algorithms, this method also has the possibility of being copied maliciously and printing invoices

Moreover, the content of the invoice generated by the QR code is based on plain text. Therefore, the private part of the content can be seen after scanning with a general-purpose QR code reader, and there is a possibility of leakage of the private data of the invoice.

At the same time, if you need to compare the scanned data with the relevant data of the tax bureau, you must ask the tax bureau to provide relevant data. When the service of the tax bureau is interrupted, authenticity cannot be verified.

At present, the existing QR code scanning technology tends to be a means to solve the problem of rapid input, but cannot be used as an effective basis for identifying the authenticity of invoices

[0007] The existence of these problems has caused the tax bureau and taxpayers to have many difficulties in identifying the authenticity of the invoice content, invoice source and other information. They can only rely on the experience and professional knowledge of tax or accounting personnel.
