Embodiment 1

[0037] This embodiment provides a two-dimensional code-based label identification method, such as image 3 shown.

[0038] Design process of the present invention is as follows:

[0039] 1. Collect label information

[0040] The label information here is generally but not limited to: the name of the subject to be protected, the production time of the subject, the main configuration of the subject, the serial number of the subject, etc.

[0041] The above-mentioned subjects can be machinery equipment, food, daily necessities, etc. The collection method can be manual input, form data upload, language input, etc.

[0042] 2. Generate a "QR code" and print it together with the label

[0043] The "two-dimensional code" mentioned above is a high-capacity two-dimensional code. The "QR code" can support the total amount of label information, that is, the label information can be encoded as binary data and stored in the "QR code". The generation process of the "QR code" is an ind...

Embodiment 2

[0048] This embodiment provides a two-dimensional code-based label identification and identification. The device contains programs such as "two-dimensional code" analysis and decryption. The above-mentioned equipment can be divided into the following five parts:

[0049] Input part: used to accept "QR code";

[0050] Parsing part: Contains the "QR code" parsing program, which is used to parse the "QR code" and obtain encrypted data;

[0051] Decryption part: Use the asymmetric secret key in the device to decrypt the data, and obtain the signature part information according to the integration rules;

[0052] Comparison part: used to compare signatures;

[0053] Presentation part: it is used to present the result, and the presenting method can be a variety of two-way difference or three-way difference.

[0054] The device type can be: pad, mobile phone, custom android device, etc. The above-mentioned mobile phone may use an app on the mobile phone, or may be a small program o...

Abstract

The invention relates to the field of data identification, in particular to a two-dimensional code technology. The invention provides a label identification method based on a two-dimensional code. Themethod comprises the steps of 1, obtaining encrypted data of the two-dimensional code; 2, decrypting the encrypted data to obtain label data; step 3, comparing the label data with a signature in thelabel identification equipment; and step 4, presenting a comparison result. The technical problems that in the prior art, a label identification mode is high in dependence on a network, poor in adaptability and low in safety are solved, the anti-counterfeiting adaptability is improved, the anti-counterfeiting cost is saved, and the privacy security of data is protected.

Description

technical field [0001] The invention relates to the field of software methods, in particular to two-dimensional code technology. Background technique [0002] Two-dimensional codes are widely used, especially in high-tech industries, storage and transportation industries, wholesale and retail industries, and other industries that need to quickly label information on items. Prior art one is the Chinese patent application whose patent publication number is CN208538405U, and its technical scheme is as follows figure 1 shown. It discloses a mother-in-picture code anti-counterfeiting label. In prior art one, the authenticity of the two-dimensional codes can be judged only by combining the two-dimensional codes on the inner and outer packaging. However, this setting limits its external packaging, and only a certain packaging can be used to put a specific product. This will cause great inconvenience to the generation during the actual operation and processing. Especially the v...
