Detailed Description

For the convenience of understanding by those skilled in the art, the structure of the present invention will now be described in further detail with reference to the accompanying drawings: it should be understood that, in this embodiment, the steps mentioned in this embodiment may be performed sequentially or sequentially, or may be performed simultaneously or partially, unless specifically stated otherwise.

In this embodiment, as used herein, the term "two-dimensional code" may be considered synonymous with and/or referred to as: the common two-dimensional Code is QR Code, which is a coding mode which is superpopular in recent years on mobile equipment, and can store more information and represent more data types than the traditional Bar Code Bar Code. The two-dimensional bar code/two-dimensional code (2-dimensional bar code) is a graph which is distributed on a plane (in a two-dimensional direction) according to a certain rule by using a certain specific geometric figure, is alternately black and white, and records data symbol information; the concept of 0 and 1 bit streams forming the internal logic foundation of a computer is skillfully utilized in code programming, a plurality of geometric shapes corresponding to binary are used for representing literal numerical information, and the literal numerical information is automatically read through an image input device or an optoelectronic scanning device to realize automatic information processing: it has some commonalities in barcode technology: each code has its specific character set; each character occupies a certain width; has a certain checking function and the like. Meanwhile, the system also has the function of automatically identifying information of different rows and processes the rotation change points of the graphics.

In this embodiment, the first terminal and the second terminal may be one or more of a computer, a handheld smart device, a smart phone, etc., which may implement the method described in this embodiment, and are not limited herein.

Referring to fig. 1, a two-dimensional code-based information transmission method includes the steps of:

s1, acquiring or identifying a plurality of pieces of information to be transmitted, wherein the information to be transmitted is sourced from a first window of a first terminal.

In this step, the information to be sent may be text, picture, file, etc., if text, means such as copying text by frame selection and text recognition may be adopted, and if picture, file, etc., may be obtained by downloading or saving. Referring to fig. 2, the information to be sent is derived from the first window of the first terminal, in this embodiment, the first window includes a table in a fixed format of the applicant, the cardholder, the contact phone, etc., information to be filled in by the user, such as leaf three, 2123, 13966666666, etc., and corresponding picture information, such as an identification card copy, etc. The method for downloading or saving the pictures and the files is implemented by adopting a method for clicking by simulating a mouse. This is because the location of the information within the first window is fixed and it is only necessary to simulate a mouse click at the first terminal. The information filled in by the user, such as leaf three, 2123, 13966666666, and the corresponding picture information 2 (8) such as an identification card copy, png is information to be transmitted, which needs to be acquired or identified in the application.

S2, adding corresponding description to each piece of information to be transmitted, and packaging all pieces of information to be transmitted and all descriptions into data to be transmitted;

in the step, corresponding descriptions are added to the information to be transmitted respectively, for example, description "applicant" is added to "leaf three", and description "identity card copy" is added to "2 (8) & png" file. And respectively obtaining all groups of data corresponding to the to-be-transmitted and the description one by one, and then packaging all the to-be-transmitted information and all the descriptions into to-be-transmitted data.

S3, dividing the data to be transmitted into a plurality of sub-data to be transmitted.

In this step, the data to be transmitted is divided into a plurality of small data segments as subfiles to be transmitted. For example, a 100k file is divided into 1000 parts, resulting in 1000 data segments of 0.1 k.

And S4, generating a corresponding two-dimensional code image according to the two-dimensional code coding rule by each sub-data to be transmitted.

The two-dimensional code coding rule belongs to the prior art, and for example, under the condition that the error correction level is H, the two-dimensional code coding rule codes: 01234567 then:

1. the numbers are divided into three groups 012345 67.

2. Converting them into binary 012 to 0000001100;345 to 0101011001; 67. turned into 1000011.

3. These three bins are concatenated 0000001100 0101011001 1000011.

4. The number of digits is converted into binary (version 1-H is 10 bits) and the binary of 8 digits is 0000001000.

5. The digitally encoded flag 0001 and the encoding of step 4 are added to the previous step 0001 0000001000 0000001100 0101011001 1000011.

6. And (3) taking 0 as a white point and 1 as a black point in the code, and filling the corresponding black point or white point into the two-dimensional code image.

According to the two-dimensional code encoding rule, a plurality of small data segments can be converted into one-to-one corresponding two-dimensional code images. After the file is segmented in the step S3, the size of the data segment is small, so that the data quantity borne by the two-dimensional code can be met. For example, 177x177, the maximum data size that can be carried by the two-dimensional code corresponding to the matrix is 2953 bytes. Through the segmentation of the step S3, the size of the single data segment is adjusted to be within the bearing capacity of the single two-dimensional code, so that the subsequent two-dimensional code coding rule is met. In this embodiment, according to the text or file in fig. 2, two of the two-dimensional code images are shown in fig. 3-4 according to the two-dimensional code image aggregate obtained by the above steps.

And S5, displaying all the two-dimensional code images through a screen of the first terminal.

In this embodiment, all the two-dimensional code images are provided for subsequent steps to be read in a manner of displaying all the two-dimensional code images. The two-dimensional code image display modes are numerous, such as cyclic display, sequential display, and also can display a plurality of two-dimensional code images at a time through a screen, so that subsequent steps can be sequentially read. The two-dimensional code image may be displayed in other manners, which is not limited herein.

And S6, acquiring and identifying all the two-dimensional code images through a camera connected to the second terminal, and analyzing to obtain sub-data to be received corresponding to each two-dimensional code image.

In the step, the two-dimensional code images are identified through the cameras connected with the second terminal, and information carried by all the two-dimensional code images is further identified. Referring to fig. 5, the image window in fig. 5 is an image of the first window obtained by the camera. The two-dimensional code shown in the detail_page in fig. 5 is a two-dimensional code image recognized in the first window.

And S7, splicing all the sub-data to be received to obtain complete data to be received.

In this step, after all the sub-data to be received are obtained, the sub-data are spliced, and there are many modes of splicing the sub-data, for example, the sub-data are spliced sequentially in sequence through the front-to-back sequence displayed by the two-dimensional code image, or the sub-data are sequenced and spliced in modes of numbering and the like, which are not limited herein. The aim of the step is to splice all the sub-data to be received and obtain complete data to be received, wherein the data to be received and the data to be sent are identical.

S8, unpacking the data to be received to obtain the information to be received and the description, and recording the information to be received into a second window of a second terminal according to the description.

Through S7, the complete data to be received is obtained, the data to be received is unpacked to obtain the information to be received and the description, the system knows the information contained in the data to be received and the position corresponding to the information, and the information to be received is input into a second window of a second terminal according to the description. Referring to fig. 6, for example, the description of "leaf three" is "applicant", then "leaf three" is input according to the dialog box corresponding to "applicant" in the second window; the description of the "2 (8) & png" file is "identity card copy", and then the "2 (8) & png" file is selected according to the dialog box corresponding to the "identity card copy" in the second window. In the step, information is input in a mode of simulating mouse clicking.

Some preferred methods by which the present invention may be implemented are described below.

In this step, since the information to be sent generally includes one or more of text, image and file, for text, the step can be identified by using a text recognition algorithm, that is, an algorithm for converting image into text, because on some terminals, text cannot be selected in a frame or copied, and meanwhile, the position to be sent is generally fixed in the first window, so that text can be identified by using the text recognition algorithm.

the location and/or name of the information is obtained,

In this step, the method of adding the name has been described in detail in the above step S1.

The step may also describe the information to be transmitted by location, where the location may be determined, for example, by coordinates (x, y) on a screen, and then, in the recording process, the information of coordinates (x, y) on the screen of the first terminal is associated with coordinates (a, b) on the screen of the second terminal according to a preset location association, so that the information of coordinates (x, y) on the screen of the first terminal is filled into the frame of coordinates (a, b) on the screen of the second terminal.

Further, before dividing the data to be sent into a plurality of sub-data to be sent, the method includes the following steps:

and S3.1, compressing the data to be sent. The purpose of this is to compress the data to be transmitted, reducing the useless data or compressing redundant data, thereby reducing the size of the data to be transmitted. The method is characterized in that the information quantity carried by the two-dimensional code is small, the number of required divisions can be correspondingly reduced after the data to be transmitted is compressed, the probability of omission and errors in the subsequent reading and splicing can be reduced, and the probability of obtaining complete data to be received is greatly improved.

s3.2, acquiring a preset data block capacity, wherein the size of the data block capacity is smaller than or equal to the size of information quantity which can be carried by a single two-dimensional code image; the preset data block capacity, that is, the maximum data amount that each two-dimensional code can bear, the size of the matrix of the two-dimensional code is various, the minimum Version 1 (that is, the size 1) is a matrix of 21x21 (composed of 21 rows and 21 columns of black and white pixels), and the maximum Version 40 (that is, the size 40) is a matrix of 177x 177. (consisting of 127 rows and 127 columns of black and white pixels). Therefore, the size, the data capacity and the like of the two-dimensional code matrix provided by the step in the subsequent step are informed by presetting the data block capacity so as to be convenient for the subsequent step to carry out.

And S3.3, dividing the data to be transmitted into a plurality of sub-data to be transmitted according to the size of the database capacity. The function of this step is to divide the sub-data to be transmitted according to the size of the database obtained in step S1.2, for example, the data to be transmitted having a size of 100k, and the data block size of 1k, and divide the data to be transmitted into 100 parts, each 1k.

s5.1, acquiring a refresh rate of a screen of the first terminal; typical screen refresh rates are 60Hz, 120Hz, 144Hz, etc. This step obtains the refresh rate of the screen of the first terminal.

S5.2, displaying all the two-dimensional code images through the screen circulation of the first terminal at a rate smaller than or equal to the refresh rate. The aim of the step is that the two-dimensional code images are circularly displayed at the same position of the screen, the refresh rate of the two-dimensional code images needs to be set, and the refresh rate is smaller than that of the screen, so that the two-dimensional code images cannot be omitted. For example, the refresh rate of the screen is 60Hz, that is, 60 times per second of screen refresh, 60 pictures are displayed, and if the refresh rate of the two-dimensional code is set to be about 60Hz, 30Hz or the like, the full display in the screen can be realized. For example, if the refresh rate of the screen is 60Hz and the refresh rate of the two-dimensional code is 120Hz, the screen will not display 60 two-dimensional code images therein.

In this embodiment, all the two-dimensional code images can be displayed on the screen of the first terminal in a continuous circulation manner, for example, the 1 st two-dimensional code image, the 2 nd two-dimensional code image, the 3 rd two-dimensional code image … ith two-dimensional code image are sequentially displayed, and then the 1 st two-dimensional code image, the 2 nd two-dimensional code image, the 3 rd two-dimensional code image … ith two-dimensional code image are displayed again. And the method is continuously circulated so as to facilitate the subsequent reading, and simultaneously, all the two-dimensional code images are circularly displayed, namely all the two-dimensional codes are continuously displayed on the screen, so that in the step of subsequent reading, if the step is not read, is less read, is mispread and the like, the method can be returned to the step again for re-reading, and the data is prevented from being damaged and missing.

s5.3, acquiring the resolution of a screen of the first terminal;

s5.4, displaying all the two-dimensional code images in a circulating way through the screen of the first terminal with definition which is larger than or equal to the resolution.

The principle of this step is similar to that of S5.1-S5.2, and the resolution of the screen is varied, for example 1080p,2k, 4k, etc. If the definition of the two-dimensional code image is smaller than the resolution of the screen, the partial lattice of the two-dimensional code is possibly lost.

and S3.4, adding a data head to each sub-data to be transmitted, wherein the data head at least comprises one or more of the number, the total number and the magic word of the sub-data to be transmitted. The header may be considered as a special reserved field of defined bit length appended to the front of the data packet for the carrying and transmission of control information. When a packet reaches its destination, this field will be separated and discarded because the packet is processed and unpacked in the corresponding reverse order of each protocol layer. In this step, a data header is added to each sub-data to be sent, so that the second terminal is informed of how many data the total amount of data is and what data the current data is when receiving and analyzing the data, and the file is convenient to check and splice subsequently.

it is determined whether all subfiles to be received have been received,

The step is used for judging whether the information represented by all the two-dimensional code images is received or not. For example, the total number of data transmitted at this time is 100 and the numbers are 001, 002, 003 and … respectively in the header, but when only 99 data are collected after one reception and data with number 050 are omitted, the process returns to the previous step to receive data again.

Further, the error correction level of the two-dimensional code image is set to be M. The error correction level of the two-dimensional code comprises L, M, Q, H four stages, wherein 7% of the codes at the L level can be corrected, 15% of the codes at the M level can be corrected, 25% of the codes at the Q level can be corrected, and 30% of the codes at the H level can be corrected. In this embodiment, the error correction level is set to M. The two-dimensional code has an "error correction function". The data can be automatically restored even if the code becomes dirty or corrupted. This "error correction capability" has multiple levels, and the user can select the corresponding level according to the use environment. The error correction capability is also improved by increasing the level, but the encoding size is also increased due to the increased data size. The error correction level is set to M, which can well balance data transmission and error correction.

After the data to be sent is obtained through the first terminal, the method comprises the following steps:

encrypting the data to be sent; in the step, the data to be sent is converted into a text encoded by Base64 after being encrypted, and then the file corresponding to the text is subjected to subsequent operation.

decrypting the data to be received. In this step, the data to be received is the same as the data to be transmitted, that is, the text encoded by the Base64, and the text encoded by the Base64 is decrypted by this step, so that the required original data is restored.

Through the encryption-decryption steps, the data transmission is effectively protected, and other illegal molecules are prevented from acquiring the original data.

Example two

An information transmission system based on two-dimension codes comprises the following modules:

the segmentation module is used for acquiring data to be transmitted through the first terminal and segmenting the data to be transmitted into a plurality of sub-data to be transmitted;

and the splicing module is used for splicing all the sub-data to be received to obtain complete data to be received.

The working principle of the present embodiment is the same as that of the first embodiment, and will not be described here again.
