Embodiment 1

[0022] Embodiment 1, see image 3 As shown, the two-dimensional code of this embodiment includes: at least two components 11 . All the components 11 are spliced ​​and combined according to the sorting rules to obtain a two-dimensional code, and each part of the components 11 is associated with a different identifiable mark 12, and the sorting rule is formulated according to each identifiable mark 12. In a specific implementation, the identifiable mark 12 may be a number, a letter, a symbol, or any combination thereof, and the position of the identifiable mark 12 may be all located outside the edge of its associated component 11, that is, as image 3 As shown in , either the identifiable logo 12 is completely covered on the associated component 11, or the identifiable logo 12 is partially covered on the associated component 11, and the rest is located outside the edge of the associated component 11. Since the two-dimensional code has strong error tolerance, it will not affect ...

Embodiment 2

[0024] Embodiment 2, see Figure 4 As shown, the decoding method of the two-dimensional code of this embodiment is used to decode the two-dimensional code of the above-mentioned embodiment 1, and includes the following main steps:

[0025] S21. Obtain all components of the two-dimensional code.

[0026] The specific method can be that the user takes pictures of each part of the components one by one through the smart terminal. It can also be disassembled and obtained by the user from the product package.

[0027] S22. Splicing and combining all the components according to the sorting rules to obtain the two-dimensional code.

[0028] The specific splicing and combination process is to identify the identifiable marks associated with each part of the components; sort the identified identifiable marks according to the sorting rules to obtain the sorting results; and then complete the splicing and combination according to the sorting results.

[0029] S23. Decode the spliced ​​...

Abstract

The invention provides a two-dimension code and a method for decoding the two-dimension code and relates to product coding. The method is used for solving the problem that according to an existing two-dimension code technology, illegal decoding is prone to conduction. The two-dimension code comprises at least two parts of components. The components are spliced and combined according to an ordering rule to obtain the two-dimension code. The parts of components are associated with different recognizable identifications and the ordering rule is made according to the recognizable identifications. The method comprises the steps that all the components of the two-dimension code are obtained; the components are spliced and combined according to the ordering rule to obtain the two-dimension code; the two-dimension code obtained by splicing and combining is decoded. According to the two-dimension code and the method for decoding the two-dimension code, illegal decoding can be effectively avoided.

Description

【Technical field】 [0001] The invention relates to product coding, in particular to a two-dimensional code and a decoding method for the two-dimensional code. 【Background technique】 [0002] The current two-dimensional code has only a single pattern, which can be decoded if the complete pattern is obtained. [0003] In order to avoid decoding by unauthorized persons, people usually use a "scratch layer" to partially or partially cover the QR code, see figure 1 , figure 2 As shown, the "scratch layer" needs to be cleared before decoding. Or hide the two-dimensional code in some parts that are not easy to detect or need to be destroyed to a certain extent before it can be found. [0004] Although the above methods can also prevent unauthorized persons from decoding, due to the cover method, it is easy for users to find the existence of the QR code, or the fault tolerance of the QR code can be used to completely decode only a part of the cover. out the entire information. ...
