Tax-control safety two-dimensional code encoding and decoding processing method

Abstract

The invention discloses a tax-control safety two-dimensional code encoding and decoding processing method. By means of the method, a tax-control safety two-dimensional code generated through the method has a plurality of levels of tax-control safety protection, anti-counterfeiting and safety performance of the tax-control safety two-dimensional code is improved, electronic signature information carried by the code can serve as a tool carrying out off-line authenticity identification on the condition of separation from the internet, the problem that when electronic bill information is transmitted through the two-dimensional code in the prior art, the authenticity identification is limited by network conditions and time is solved, and tax-control safety of the tax-control safety two-dimensional code is effectively enhanced. The tax-control safety two-dimensional code decoding processing method not only can prevent illegal leakage of useful information in the tax-control safety two-dimensional code, but also can immediately identify authenticity of the electronic bill information contained in the tax-control safety two-dimensional code off-line on the condition that the internet is not relied on, and therefore the tax-control safety of the tax-control safety two-dimensional code during the decoding process is further improved.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting of electronic bills, in particular to a method for encoding and decoding two-dimensional codes for tax control safety. Background technique [0002] Electronic bills are a product of the information age. Based on computers and modern communication technology networks, electronic bills store business capital information in the computer system in the form of data messages, and can be transmitted and circulated in the form of electronic information transmission to realize the traditional. Summary, payment, circulation, financing, settlement, credit and other functions of paper bills. QR code is a very commonly used form of electronic information transmission for electronic invoices. The electronic bill code, bill number, and bill content information (such as unit name, address, telephone number, amount of funds, billing time, etc.) Different types of electronic invoices contain different...

AI Technical Summary

Problems solved by technology

Such an inspection method is not only cumbersome and lagging, but also needs to rely on the Internet. When the Internet cannot be connected, the authenticity inspection of the two-dimensional code of the electronic bill cannot be realized.

This has led to the fact that under the existing technical conditions, in some business processes that require immediate access to electronic bills through the QR code, or in some applications that cannot immediately connect to the Internet, it is impossible to record the electronic receipts recorded in the QR code. Verify the authenticity of the bill content information
