Embodiment example 1

[0143] For example, in the application of mobile value-added services, values ​​such as L=1, n=9, M=N=3, 4, 5, , , etc. can be set. In the application of mobile value-added services, the amount of data is generally not particularly large, and there is no need to link the data, that is, it is not necessary to use links of multiple QR codes. As shown in FIG. 1, L=1, n=9, M=N=3.

Embodiment example 2

[0145] When it is applied to document storage, etc., especially for confidentiality and large-scale document storage, several methods of two-dimensional barcodes can be used to achieve effective storage of information.

[0146] 1. For large-capacity information, the information volume of the two-dimensional barcode can be set according to the information capacity of each A4 paper. For example, the information on each page (such as A4 paper) can be compiled into a two-dimensional barcode, and the information contained in the page can be generated into a two-dimensional barcode, which can be printed on a certain part of the page, so that For the reading and saving of information on this page; as shown in Figure 10.

[0147] 2. For some content such as news or book descriptions, which are not particularly important, you can only publish a title and a brief description, and the specific content will generate a two-dimensional barcode; only the two-dimensional barcode decoder holdi...

Embodiment example 3

[0153] The large-capacity two-dimensional code of the present invention is used as an implementation method of public codes. The two-dimensional code of the present invention can be used as an open standard two-dimensional code after being standardized like a QR code and a DM code. That is, the encoding method, encryption method, compression method, and various parameters of the two-dimensional code are made public, which is convenient for the free use of the public. Including that the public can freely edit and generate various required two-dimensional code codeword information through coding software, and decode various codewords through two-dimensional code decoding software to obtain original information.

Abstract

The invention discloses a novel high-capacity two-dimensional barcode and a system suitable for mobile phones and special equipment, and encoding and decoding methods and applications thereof. The high-capacity two-dimensional barcode is composed of a positioning area, a positioning interval area and a data area, wherein the positioning area is composed of a positioning dotted outline border, positioning points, a positioning information unit and a timing unit; the data area is composed of a header file area and a code information area; the information compression technology, the information coding technology and the information encryption technology are used in the two-dimensional barcode; the two-dimensional barcode can control the error correction level of error correction encoding, the amount of encoding information, the compression method of the information and the encryption method of the information; and in the process of decoding, the dynamic decoding can be performed according to the header file information of the two-dimensional barcode. The two-dimensional barcode is high in capacity, can be positioned quickly so as to carry out all-round code reading, can encrypt information, and can read the information of the two-dimensional barcode by designated special decryption keys or designated decryption devices.

Description

technical field [0001] The large-capacity two-dimensional barcode disclosed in the present invention relates to a two-dimensional barcode technology suitable for industrial applications and mobile value-added services, relates to the code type and code word structure of the two-dimensional barcode, relates to information error correction coding and decoding technology, information Encryption and decryption technology, information compression and decompression technology, image recognition and image processing technology. Background technique [0002] Two-dimensional barcodes are developed on the basis of one-dimensional barcodes, and the amount of information is dozens or even hundreds of times that of ordinary barcodes. Two-dimensional barcodes include stacked two-dimensional barcodes produced by stacking multiple one-dimensional codes vertically on the basis of the traditional one-dimensional barcode coding principle and a matrix encoded by different distributions of black...
