Problems solved by technology

Although it mentions the use of Hamming code to check and correct the encoded data, it judges whether the encoded data is correct based on whether the serial number is continuous, that is, combines multiple encoded data to determine whether the encoded data is lost, and cannot prevent a single QR code illegal operation of

Embodiment 1

[0066] like figure 1 As shown, this embodiment proposes a Hamming code-based QR code authentication method, including:

[0067] Step S1, encode the QR code information to generate a preliminary QR code;

[0068] In the present invention, the authentication information is embedded in the preliminary QR code. Therefore, before diving into the authentication information, a preliminary QR code needs to be generated, including:

[0069] Step S1.1, data analysis: analyze the QR code information, determine the corresponding coded character type, and select an appropriate error detection and correction level;

[0070] Specifically, the QR code is provided with different versions (kinds) of 1 to 40, and each version has an inherent symbol structure (number of symbols). Symbols are the square black and white dots that make up the QR code. "Symbol structure" refers to the number of symbols in a two-dimensional code. Starting from version 1 (21 symbols x 21 symbols), it is incremente...

Embodiment 2

[0112] like Figure 5 As shown, this embodiment proposes a Hamming code-based QR code authentication system, including:

[0113] An encoding module for encoding the QR code information to generate a preliminary QR code;

[0114] a grouping module for grouping the data modules in the preliminary QR code;

[0115] an embedding module for embedding authentication information into the preliminary QR code to obtain a final module matrix;

[0116] a mask module for performing a mask operation on the final module matrix;

[0117] The authentication module is used to authenticate the information of the QR code.

[0118] In the present invention, the authentication information is embedded in the preliminary QR code. Therefore, before sneaking into the authentication information, a preliminary QR code needs to be generated. The encoding module specifically includes:

[0119] The data analysis module is used to analyze the QR code information, determine the corresponding coded chara...

Abstract

The invention discloses a QR code authentication method and system based on Hamming codes. The QR code authentication method comprises the steps of S1, encoding QR code information to generate preliminary QR codes; S2, grouping the data modules in the preliminary QR code; S3, embedding 3-bit authentication information into the preliminary QR code by a (7,4) Hamming error correction mechanism to obtain a final module matrix; S4, carrying out mask operation on the final module matrix; and S5, authenticating the information of the QR code. The method not only resists printing and photographing, but also has the characteristic of high information capacity. In the method, authentication information is embedded into the modules in the module matrix through the Hamming codes (7, 4). Under the fixed QR code error correction level, more authentication information can be embedded in the QR code error correction method.

Description

technical field [0001] The invention relates to the field of safety authentication, in particular to a method and system for safety authentication of QR codes based on Hamming codes. Background technique [0002] With the advent of the mobile Internet era, the development of the information industry driven by "Internet +" has made a major breakthrough. As the most iconic product of the Internet age, QR code breaks the constraints of the original industry marketing model by virtue of its online-offline information docking advantages, and promotes the transformation of traditional industrial structure to "Internet +" industry. Nowadays, QR codes are used more and more widely. In the field of e-commerce, payment by scanning codes has gradually replaced the traditional cash payment mode. This new payment method is changing people's consumption habits; in the field of mobile social networking, more and more social software such as WeChat, QQ, etc. Scan QR codes to obtain user i...
