Embodiment Construction

[0049] refer to figure 1 , the hierarchical structure of the multi-dimensional two-dimensional code anti-counterfeiting label described below in the present invention is that the two-dimensional code identification layer includes a general code and a proprietary code, the two-dimensional code identification layer is covered with an anti-counterfeiting ink layer, and the anti-counterfeiting ink layer is covered with a laser Security layer.

[0050] The present invention is based on the multidimensional two-dimensional code generation method of proprietary code, implements according to the following steps:

[0051] Step 1. Analyze the encoded data, determine its character type, select an appropriate mode, and encode each sequence (the counting indicator lengths of different modes and different versions are different); the user specifies the version number adopted, and confirms the correction level and error detection;

[0052] Step 2, data encoding, convert the input data into...

Abstract

The invention discloses a proprietary code-based multidimensional two-dimensional code generation method and a proprietary code-based multidimensional two-dimensional code decoding method. A data partof a multidimensional two-dimensional code comprises a universal code and a proprietary code; the universal code is used for adding a universal code end mark 0000 after generating a data bit stream;at the moment, if the proprietary code exists, a mode indicator, a counting indicator and a data bit stream of the proprietary code are continuously added after the end mark; and finally, terminators0000 of all the pieces of data are added. When data information with the proprietary code is decoded, if the end mark of the universal code is decoded, the decoding is not finished and should be continued until the end mark of the proprietary code is ended. The multidimensional two-dimensional code generation method is low in printing cost, high in printing speed and small in printing area.

Description

technical field [0001] The invention belongs to the technical field of two-dimensional code anti-counterfeiting, and relates to a method for generating a multi-dimensional two-dimensional code based on a proprietary code, and also relates to a method for decoding a multi-dimensional two-dimensional code based on a proprietary code. Background technique [0002] With the rapid development of economy and technology, the demand for commercial anti-counterfeiting is increasingly strong. As a carrier of information dissemination, two-dimensional codes are playing an increasingly important role in the field of anti-counterfeiting. Currently commonly used or well-known two-dimensional code encoding mechanisms include DataMatrix, Maxi Code, QR Code, Chinese Sensible Code, etc. Among them, the Quick Response Code (QR code) was developed by Denso Wave and later became an international standard. Now it has rapidly become a widely used inventory tracking and identification method especi...
