Problems solved by technology

[0003] At the same time, with the popularization of two-dimensional code applications, people need to include some private content in the two-dimensional code, and it is not possible to limit the scanning and recognition of two-dimensional codes by general-purpose two-dimensional code scanning equipment. The existing standard format of two-dimensional codes is only The start code and stop code and the data content between them are combined into a piece of practical content, which cannot achieve the ideal processing effect

Embodiment 1

[0040] The embodiment of the present invention provides a two-dimensional code with a security function and its application method. The method can realize the addition of new encrypted content on the basis of compatibility with the standard two-dimensional code by extending the encoding method of the standard two-dimensional code. Function.

[0041] This embodiment provides a processing flow of a two-dimensional code application method as follows: figure 1 As shown, the following processing steps are included:

[0042] Step S110, encoding the plaintext information to obtain the plaintext part of the two-dimensional code, and encoding the ciphertext information to obtain the ciphertext part of the two-dimensional code.

[0043] According to the standard encoding rules of the two-dimensional code, the plaintext information is encoded to obtain the plaintext part of the two-dimensional code, and the plaintext part of the two-dimensional code includes a plaintext start symbol and...

Embodiment 2

[0060] The schematic diagram of the application of the embodiment of the present invention in train ticket sales is as follows image 3 mentioned. Assume that the plain text of a train ticket QR code contains boarding station, arrival station, seat number, departure date and time, fare, and online ticket purchase website, and the cipher text contains the name and ID number of the passenger.

[0061] In the train ticket sales system (1), that is, the server first sets the encryption and decryption key, and then exports the decryption key (2) to a dedicated two-dimensional code scanning device, that is, a dedicated two-dimensional code scanning terminal (3).

[0062] When someone buys a ticket, according to the information provided by the buyer, firstly, the train ticket’s boarding station, arrival station, seat number, departure date and time, fare, online ticket purchase website and other plain text information and the buyer’s name and ID number The encryption result is splic...

Embodiment 3

[0067] This embodiment provides a two-dimensional code application device 400, the schematic diagram of which is shown in Figure 4 shown, including:

[0068] An encoding processing module 410, configured to encode the plaintext information to obtain the plaintext part of the two-dimensional code, and encode the ciphertext information to obtain the ciphertext part of the two-dimensional code;

Abstract

The embodiment of the invention provides a two-dimensional code application method and device. The method mainly comprises the steps that cleartext information is encoded to obtain a two-dimensional code cleartext portion, and ciphertext information is encoded to obtain a two-dimensional code ciphertext portion; the two-dimensional code cleartext portion and the two-dimensional code ciphertext portion are constructed according to a set information combination mode to form two-dimensional codes; the two-dimensional codes are scanned and recognized, the two-dimensional code cleartext portion and the two-dimensional code ciphertext portion are obtained, the two-dimensional code cleartext portion is decoded to obtain cleartext information, and the two-dimensional code ciphertext portion is decoded and decrypted to obtain original text information corresponding to ciphertext information. According to the method and device, the aim that cleartext and ciphertext in the two-dimensional codes do not interfere with each other and each achieve special functions of their own is realized. General two-dimensional code reading equipment can be used for reading the cleartext information, and dedicated two-dimensional code reading equipment can be used for reading the cleartext information and the ciphertext information. Safety of two-dimensional code application is effectively improved, and the application scenes of two-dimensional codes are enriched.

Description

technical field [0001] The present invention relates to the technical field of two-dimensional code application, in particular to an application method and device of two-dimensional code. Background technique [0002] In recent years, two-dimensional code technology has been widely used in logistics, ticketing, document storage, electronic vouchers and many other fields. However, all the two-dimensional code standards do not specifically consider the application integration of security data, and the existing two-dimensional code applications are to generate two-dimensional codes according to the standard format and apply them. [0003] At the same time, with the popularization of two-dimensional code applications, people need to include some private content in the two-dimensional code, and it is not possible to limit the scanning and recognition of the two-dimensional code by the general two-dimensional code scanning equipment. The existing standard two-dimensional code is o...
