Referring to Figure 5, it is a flowchart of a method for generating a three-dimensional code label in an embodiment of the present invention. The generation of a three-dimensional code label specifically includes the following steps:

S101. Obtain business data that needs to be carried on a three-dimensional code label. Service data can be obtained through user input, or by accessing interfaces of other applications or systems.

S102. Determine the size of the service data area 1. Specifically, it is to judge whether the amount of business data that needs to be carried exceeds the amount of data that can be carried by the size of the set business data area 1, and if it exceeds, further judge whether it exceeds the maximum amount of data that can be carried by the business data area 1; If the maximum amount of data that can be carried by 1 is displayed, it will prompt "Unable to generate a three-dimensional code label", otherwise, the size of business data area 1 will be automatically expanded according to the amount of business data that needs to be carried. If it is judged that the amount of service data to be carried is within the range of the amount of data that can be carried by the set size of the service data area 1, then the size of the service data area 1 is determined with the set parameters.

S103, according to the size of the service data area 1, determine the horizontal length of the horizontal control data area 21 and the vertical length of the vertical control data area 22. The way to determine it is that the horizontal length of the horizontal control data area 21 is equal to the border size of the corresponding business data area 1 plus the width of the "L"-shaped separation figure 3 . The longitudinal length of the vertical control data area 22 is equal to the frame size of the corresponding business data area 1 plus the width of the "L"-shaped separation figure 3, so that the image boundaries of the business data area 1 and the control data area are aligned, ensuring the overall outline of the three-dimensional code label is a rectangle.

S104, encode the service data to be carried, generate and cache an image conforming to the display size of the service data area; according to different application environment requirements, before encoding, the service data to be carried can be encrypted and then encoded. Encoding and encryption techniques can be performed according to existing technologies.

S105. Acquire control data such as signature information, authorization information, secret key information, and coordinate information that need to be carried in more than one control data area. The acquisition method can be manual input or through an interface of other applications or systems.

S106, encode the control data that needs to be carried in the control data area, generate and cache the displayed image conforming to the size of the horizontal control data area 21 and the vertical control data area 22. Wherein, the control data can be divided into two parts and displayed in the horizontal control data area 21 and the vertical control data area 22 respectively. The horizontal control data area 21 and the vertical control data area 22 can also respectively carry and display two different control data. For example, the horizontal control data area 21 is used to carry user names, and the vertical control data area 22 is used to carry corresponding password data; the horizontal control data area 21 is used to carry signature data, and the vertical control data area 22 is used to carry public key data, etc. In the preferred solution, the service data area 1 and the control data area should adopt different encoding methods. The encoding methods of the control data in the horizontal control data area 21 and the vertical control data area 22 may be the same or different. According to different application environment requirements, before encoding the control data, it can be encrypted and then encoded. There are various encoding and encryption methods, which can be specifically performed according to the existing technology.

S107, acquiring and caching the image to be displayed in the image display area 4. In a preferred solution, the image in the image display area 4 is not necessary, and if there is no logo of the commodity or product or company to be displayed, it can also be filled with light or dark color.

S108, fill the coded and cached business data image, control data image, and LOGO into the business data area 1, control data area, and image display area 4 respectively to form an integral three-dimensional code label, and directly display or print it.

Referring to FIG. 6 , it is a flow chart of identification corresponding to a three-dimensional code label in an embodiment of the present invention. The identification of a three-dimensional code label specifically includes the following steps:

S201, performing overall image acquisition on the three-dimensional code;

S202. Identify the contours of the horizontal control data area and the vertical control data area. Since the width of the horizontal control data area and the vertical control data area is fixed, and there is an "L"-shaped separation figure 3 between the business data area, the contour recognition of the horizontal control data area and the vertical control data area is relatively simple. In an optional solution, positioning can be performed through the image display area 4 and images. The image display area 4 has a fixed size, is located in the lower right corner, and is located at the junction of the horizontal control data area and the vertical control data area.

S203, the step of identifying the service data area by positioning according to the contours of the horizontal control data area and the vertical control data area. Since the shape and width of the horizontal control data area and the vertical control data area are fixed, and the size, shape and position of the image display area 4 are fixed, the horizontal control data area and the vertical control data area are used to carry data. It also plays a positioning role. It gets rid of the problem in the prior art that three fixed figures are required for positioning and occupies too much information space of the three-dimensional code.

S204, dividing the images of the business data area 1, the horizontal control data area 21, and the vertical control data area 22;

S205, respectively identify the images of the business data area 1, the horizontal control data area 21, and the vertical control data area 22 and decode them through the corresponding decoding algorithm; in the preferred solution, the data in the business data area can be unencrypted, while the horizontal control data At least one of the area 21 and the vertical control data area 22 is encrypted. If the horizontal control data area 21 and the vertical control data area 22 carry user names and passwords respectively, then the horizontal control data area 21 and the vertical control data area 22 are obtained. Before the data, it is necessary to decrypt the identification results of the horizontal control data area 21 and the vertical control data area 22, and then obtain the final data. In this way, the three-dimensional code label of the present invention has the convenient characteristics of a general three-dimensional code, and can also be used for identification and control of three-dimensional code reading to meet special application requirements and improve data security. Another preferred solution is that before identifying the image in the service data area 1 and decoding it through the corresponding decoding algorithm, it is necessary to first decode the public key data in one of the horizontal control data area 21 or the vertical control data area 22, and then identify the three-dimensional code. The device can use the public key to decrypt and decode the service data area 1. Since the three-dimensional code label structure of the present invention is different from the prior art, and can independently control the type of data carried by the business data area 1, the horizontal control data area 21, and the vertical control data area 22, and whether the data is encrypted or decrypted, Therefore, in addition to the above two preferred solutions, there may be various combinations of security measures.

S206. Obtain the data carried by the service data area 1, the horizontal control data area 21, and the vertical control data area 22. When the service data area 1 carries the network address of the product or service, the horizontal control data area 21 carries the user name, and the vertical control data area 22 carries the user password, then after the three-dimensional code of the user terminal is scanned and recognized, the user can pass the service The data area 1 carries the network address access of the goods or services to obtain the goods or services, and at the same time, it can automatically log in with the user name carried by the identified horizontal control data area 21 and the vertical control data area 22 carries the user password. , Realize automatic identity identification, avoid manual input at the same time, and ensure safety.

Finally, it is noted that the above embodiments are only used to illustrate the technical solution of the present invention without limitation, other modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and spirit of the technical solution of the present invention All should be included in the scope of the claims of the present invention.
