Example one
The embodiment provides a two-dimensional code printing method and two-dimensional code printing equipment, which are shown in figures 2-5.
The preparation flow of this embodiment includes: after information coordinates and corresponding encrypted information are integrated, the information coordinates and the corresponding encrypted information are coded into the two-dimensional code; encoding the two-dimension code coordinates into the two-dimension code; and the identification equipment and the printing equipment can analyze the two-dimensional code.
The encrypted information is private information, that is, information which is specific to an individual or specific to a unit individual in the information presentation process.
The marking information is public information in the information presentation process, namely unified and standardized information. The marks correspond to the mark information one to one.
The information coordinates are used for determining the presentation bits of the encryption information; the two-dimensional code coordinate is used for presenting the original code of the two-dimensional code at the designated position.
The identification device is a device containing a decoding program. The equipment and the software can be any products based on Android, IOS, windows, linux and other systems. The recognition device has a storage block, a parsing block, and a presentation block, i.e., a peripheral connection block.
The text information typing process of the invention is shown in figure 1:
1. parsing local two-dimensional code
And analyzing the local two-dimensional code image through the identification equipment.
The local two-dimension code can be acquired through other channels such as network, bluetooth, near field communication and the like. In general, the two-dimensional code original code needs to be stored locally, and the two-dimensional code is used for final printing so as to ensure the authority and the aesthetic property of the copy file. The shot two-dimensional code picture can be used for printing in a sleeving mode under the theory, but the problems that the printing effect is poor, or the printing result cannot be used for verifying the validity of the file and the like can occur.
The form of the two-dimensional code is used in file transmission, so that information is prevented from leaking, and information safety is ensured.
2. Obtaining information coordinates and corresponding information data, and two-dimensional code coordinates
After the analysis is successful, the information coordinates and the information data corresponding to the coordinates need to be obtained by analysis from the analysis data. The information coordinates correspond to the information data one to one.
3. Presenting information data according to information coordinates
And presenting corresponding information data according to the information coordinate position.
4. According to the coordinates of the two-dimension code, the local two-dimension code is presented on the background
After the local two-dimensional code is printed by the sleeve, the local two-dimensional code appears on a paper file and can be used for checking the later paper file.
Since the two-dimensional code is difficult to be tampered and the two-dimensional code involved in the invention is a non-public technology, it can be ensured that no other company can produce the two-dimensional code except the company. Therefore, if the content on the document is obtained and is consistent with the paper document, the paper document is true and effective by using the identification device again. And if the analysis fails, the paper file is indicated to have risk.
The step optionally includes a remark process, especially one file includes a plurality of two-dimensional codes, the remark process can effectively and quickly distinguish the two-dimensional codes, and the remark process is shown in fig. 3.
The whole two-dimensional code graph is divided into two areas, and a centrosymmetric two-dimensional code data area is arranged in the middle of the graph and used for coding the two-dimensional code graph; the periphery of the data area is a two-dimensional code remark area, and the remark area can be divided into four directions, namely an upper direction, a lower direction, a left direction and a right direction.
1) The user needs to enter the encrypted information:
the encrypted information is encoded into the data area of the two-dimensional code. The type of information may be any binarizable data, such as numbers, letters, graphics. The encrypted information will eventually be encoded in.
2) Selecting a remark orientation
The remark orientation mainly refers to the orientation of a remark area surrounding the two-dimensional code data area. The direction is divided into four parts, namely, upper, lower, left and right. The user may select a single or multiple orientations. If the scheme is a multiple choice scheme, the subsequent 3-4 steps are circulated for multiple times to confirm different remark types and remark contents in different directions. Assuming the user selects 4 orientations, the user is required to repeat 3-4 steps four times.
3) Selecting a remark type:
the remark types may be: pictures and characters. The selection can assist in the generation of the final two-dimensional code image, and the generation process can be more efficient because the image generation modes of different types of information are different.
4) Inputting remark information according to the remark alternatives:
if the remark type is picture: this step provides the user with an interface to select a picture from local. Or the user may provide a URL network address for the picture. However, if the URL address is the picture type, the content of the URL address is judged to judge whether the picture type is the picture type. If not, the user is prompted to re-enter.
If the remark type is a text: this step may input a date, version number, type of information, whether related or unrelated to the encrypted information. If the encrypted information is a certificate, the text remark information can be a certificate type, a certificate issuing unit, certificate issuing time, a certificate authorization unit, current time and the like.
4) Generating two-dimensional code image with remarks
The generating program can encrypt and encode the encrypted information into binary data, and then encode the binary data into a preset image central data area to form a two-dimensional code data area. And then generating the remark information into the remark areas of the two-dimensional code one by one according to the remark directions and the remark types.
5. Connect the printer to realize the printing
