Problems solved by technology

However, there are some problems in the current application of QR codes: For example, some people store virus links in QR codes, supplemented with normal introductory texts to induce people to scan, and then engage in activities such as defrauding users of phone charges and installing malware; In code ticket anti-counterfeiting applications, if you want to add quick access links or introductory texts and private data that do not need to be cared about by ticket buyers, it is not easy to implement based on the existing national standard QR code standards, so there will be an application scenario where train tickets are fully encrypted
[0004] The disadvantage of the coding scheme of a two-dimensional code in the above-mentioned prior art is: this method does not solve the issuer authentication problem of the two-dimensional code itself, and enterprises using two-dimensional codes need to develop two-dimensional codes and generate authentication systems

Abstract

An embodiment of the invention provides a two-dimensional code coding-and-decoding and authentication method and a two-dimensional code coding-and-decoding and authentication device. The two-dimensional code coding-and-decoding and authentication method mainly comprises the steps of setting a standard coded data segment and a two-dimensional code authentication data segment in coded two-dimensional code data, wherein the standard coded data segment is separated from the two-dimensional code authentication data segment through two-dimensional code segmenting marks; and setting a two-dimensional code verification mark in the two-dimensional code authentication data segment, wherein the two-dimensional code verification mark is used for verifying whether the coded two-dimensional code data are issued by a preset two-dimensional code issuing party. The two-dimensional code coding-and-decoding and authentication method and the two-dimensional code coding-and-decoding and authentication device have advantages of effectively improving safety in accessing the two-dimensional code, conveniently and effectively performing authentication on the validity of the two-dimensional code, simultaneously accommodating an open content and a private content in the two-dimensional code data, hiding the private content, and realizing no identification for existence of the private content, and realizing no use experience reduction.

Description

technical field [0001] The invention relates to the technical field of two-dimensional codes, in particular to a method and device for encoding, decoding and authenticating two-dimensional codes. Background technique [0002] Two-dimensional code technology is widely used in many fields such as network access, fast payment, and ticket anti-counterfeiting. However, there are some problems in the current application of QR codes: For example, some people store virus links in QR codes, supplemented with normal introductory texts to induce people to scan, and then engage in activities such as defrauding users of phone charges and installing malware; In code ticket anti-counterfeiting applications, if you want to add quick access links or introductory texts and private data that do not need to be cared about by ticket buyers, it is not easy to implement based on the existing national standard QR code standards, so there will be an application scenario where train tickets are fully...
