Problems solved by technology

The disadvantage of prior art 1 is that: due to the common two-dimensional code with clear code characteristics, the decoding technology is an open technology, and if Figure 1 The QR code shown generally has fault tolerance, that is, after smearing or covering up part of the data points of the two-dimensional code, the complete data information can still be obtained, so the information in the ordinary two-dimensional code characteristic of the clear code is still easy to be stolen
[0004] Now technology can realize a two-dimensional code graphic to display specific information to specific groups, but its security is obviously not enough

Embodiment 1

[0033] This embodiment provides a two-dimensional code encoding method, such as Figure 2-5 As shown, the steps are as follows:

[0034] 1. Information collation:

[0035] Collect and organize information data, characteristic data.

[0036] The information data will be used for the parent QR code 2, mainly to present the content that needs to be expressed. The feature data will be used to generate the child QR code 1, including the parent QR code 2 type information, tag information, permission information, order information, etc. The type information of the two-dimensional code mainly includes the type of the two-dimensional code of the parent body, the shape information of the anchor point of the two-dimensional code of the parent body, the number of anchor points of the two-dimensional code of the parent body, etc.; The characteristic data on the above; the authority information is used to verify whether the reader has the authority to obtain font information.

Embodiment 2

[0047] This embodiment provides a two-dimensional code decoding method, such as Figure 6 As shown, the steps are as follows:

[0048] 1. Capture the QR code image of the offspring.

[0049]Use a decoding device to scan the two-dimensional code graphic, the decoding device includes at least one level of unique authority data, use the sub-body decoding program in the scanning device to decode all sub-volumes on the image, and obtain all sub-volume two-dimensional codes data.

[0050] 2. Verify characteristic data

[0051] After obtaining the two-dimensional code data of the child body, compare the authority information in the two-dimensional code data of the child body with the device authority pre-stored in the device. The device can only obtain information whose permission data in the child QR code data is consistent with the device permission. If the device contains the highest level of child authority, the device can obtain all child QR code data and capture parent QR c...

Abstract

The invention provides a nested QR code encoding method, which comprises the steps : S1, establishing a paternal QR code data set and a child QR code data set, the child QR code data set comprising one or more combinations of type information, mark information and permission information of a parent QR code, and sequence information; S2, forming a paternal QR code by adopting paternal QR code data;S3, forming a plurality of child QR codes arranged in sequence by adopting the child QR code data set, wherein the sizes of the child QR codes are the same as those of the positioning points of the paternal QR code; and S4, capturing data, sizes and coordinates of the paternal QR code positioning points, and sequentially placing the plurality of child QR codes at the positions of the paternal QRcode positioning points according to the sequence information. The technical problem of data security when the QR code is used as an information carrier for circulation is solved, and tampering of QRcode data is avoided, and information effectiveness is guaranteed.

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 code, as an important contemporary coding technology, is widely used in high-tech industries, storage and transportation industries, wholesale and retail industries and other industries that need to quickly label information on items. Its data capacity, recognition speed, recognition security and recognition diversity are all important considerations for the development of QR codes. [0003] Prior art one is a Chinese patent application whose patent publication number is CN109948764A, and the technical scheme is as follows: figure 1 As shown, it discloses an anti-counterfeiting two-dimensional barcode system and its encoding method. The disadvantage of prior art 1 is that: due to the common two-dimensional code with clear code characteristics, the decoding technology is an open technology, and if Fi...
