Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the related invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Fig. 1 illustrates an exemplary system architecture 100 to which embodiments of the information transfer system, method, or apparatus of the present application may be applied.

As shown in fig. 1, the system architecture 100 may include a display terminal 101, a scanning terminal 102, a network 103, and a server 104. The network 103 is used to provide a medium for communication links between the display terminal 101, the scanning terminal 102, and the server 104. Network 103 may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few.

A user may use the display terminal 101, the scanning terminal 102 to interact with the server 104 over the network 103 to send or receive messages, etc. Various client applications, such as a web browser application, a shopping application, a video playing application, an instant messaging tool, etc., may be installed on the display terminal 101 and the scanning terminal 102.

The display terminal 101 may be various electronic devices configured with a display screen to present a color patch matrix. The scanning terminal 102 may be a variety of electronic devices configured with a display screen and a camera to capture the color patch matrix. The display terminal 101 and the scanning terminal 102 may include, but are not limited to, a smart phone, a tablet computer, a laptop portable computer, a desktop computer, and the like.

The server 104 may also be a server that provides various services, such as a background application server that provides support for various applications on the display terminal 101 and the scanning terminal 102. The background application server may perform processing such as encoding on information to be sent between the display terminal 101 and the scanning terminal 102, and return a processing result (such as an information encoding set corresponding to the information to be sent) to the display terminal 101, so that the display terminal 101 and the scanning terminal 102 perform communication. And after the scanning terminal 102 returns the information matched with the processing result, the information to be sent is sent to the scanning terminal 102.

It should be noted that the information transmission method provided in the embodiment of the present application is generally executed by the display terminal 101, and accordingly, the information transmission apparatus is generally disposed in the display terminal 101.

It should be understood that the number of display terminals, scanning terminals, networks and servers in fig. 1 is merely illustrative. There may be any number of display terminals, scanning terminals, networks, and servers, as desired for implementation. For example, one display terminal may correspond to a plurality of scanning terminals. It should be noted that when the display terminal 101 has a function of encoding each character in the information to be transmitted, the server 104 may not be provided in the system 100. The display terminal and the scanning terminal in fig. 1 are also only schematic, and as long as the terminal has a display screen and/or a camera and a network communication function, the terminal can implement the functions of the display terminal and/or the scanning terminal, and has low dependency on terminal hardware.

With continued reference to FIG. 2, a timing diagram of one embodiment of an information transmission system according to the present application is shown.

The information transmission system in the embodiment may include a server, a display terminal, and a scanning terminal; the server is used for respectively encoding each character in the information to be transmitted, generating an information encoding set corresponding to the information to be transmitted and transmitting the information encoding set to the display terminal; the display terminal is used for generating a first color block matrix based on the number of the information codes in the information code set and displaying the color indicated by the color sequence corresponding to each information code in the information code set in the first color block matrix according to a pre-stored relation table, wherein the relation table stores the number in the code and the color information corresponding to the number; and the scanning terminal is used for scanning the first color block matrix, generating a first information coding set according to the relation table, and sending the first information coding set to the server, so that the server sends the information to be sent to the scanning terminal after determining that the first information coding set is matched with the information coding set.

As shown in fig. 2, in step 201, the server encodes each character in the information to be transmitted, and generates an information encoding set corresponding to the information to be transmitted.

In this embodiment, a server (e.g., the server 104 shown in fig. 1) may encode each character in the information to be transmitted by various methods, so as to generate an information encoding set corresponding to the information to be transmitted. Here, the encoding is generally to encode characters, numbers or other objects into numbers by a predetermined method. I.e., the process of converting information from one form or format to another. For example, 10-19, 20-29, etc. may be encoded in sequence in the order of the characters in the information to be transmitted. The information to be sent may be various information, such as text information, picture information, or video information. Such information is typically made up of characters, which may include, but are not limited to, numbers, letters, words, symbols, and the like.

In addition, in order to increase the number of characters expressed by the codes, the information codes in the generated information code set can be binary codes or decimal codes commonly used in a digital system, and can also be other binary codes. And the number in the information encoding is not limited to 1 and 0. Meanwhile, the digit number of the digital code in each information code can be the same or different. And to further increase the reliability of information transmission, a check bit may be added at a predetermined position (e.g., the first bit or the last bit) of each information code. The checking method may be, but is not limited to, parity checking. For example, if the sum of the numbers in the information code is odd (or even), the number on the parity bit can be 1 (or 0).

In some optional implementation manners of this embodiment, the server may encode each character in the information to be sent according to a correspondence between characters and codes in a pre-stored encoding file. The encoding file may be various files storing characters and codes corresponding to the characters, such as an XML (Extensible Markup Language) file, a data table, and the like. Meanwhile, the coding file can be obtained by the server from other servers in advance and stored locally, or can be manually stored in the server in advance.

Optionally, in order to further improve the reliability and security of information transmission, the server may also periodically update the encoding file, so as to update the information encoding set corresponding to the information to be transmitted. For example, the server may determine whether the number of uses of the encoded file from the time of storage to the current time is greater than a preset number of uses, and may update the encoded file in response to determining that the number of uses is greater than the preset number of uses. For another example, the server may determine whether a storage duration of the encoded file from the storage time to the current time is greater than a preset storage duration, and may update the encoded file in response to determining that the storage duration is greater than the preset storage duration. The preset number of times of use and the preset storage duration may be set manually or may be defaulted by the server. For example, the preset number of times of use is one, and the preset storage time is one day (24 hours).

In step 202, the server sends the information encoding set to the display terminal.

In this embodiment, based on the information encoding set generated in step 201, the server may transmit the information encoding set to a display terminal (e.g., the display terminal 101 shown in fig. 1) through a wired connection or a wireless connection.

In step 203, the display terminal generates a first color block matrix based on the number of information codes in the information code set.

In this embodiment, the display terminal may generate the first color block matrix according to the number of information codes in the information code set. For example, if the information encoding set includes 3 information encodings, a first color block matrix of 1 row and 3 columns may be generated. It should be noted that, the display terminal may be pre-stored with a color patch matrix template, and a style may be selected from the color patch matrix template to generate a first color patch matrix of the style. The color block matrix template may include color blocks and color block matrixes of different types, such as circular color blocks or color block matrixes, quadrilateral color blocks or color block matrixes, and the like. In addition, the display terminal can also determine the number of rows and columns of the first color block matrix according to the size of the display screen and the size of a single color block. For example, the width of the display screen is 6cm, and the size of the individual color blocks is 6mm × 6 mm. Wherein cm is centimeter and mm is millimeter. At this time, if the information encoding set includes 11 information encodings, the first color block matrix should include at least 2 rows because a line of the display screen can display 10 color blocks at most. The color block matrix can be 2 rows and 10 columns, and can also be 3 rows and 4 columns.

It should be noted that the size of the color block displayed on the display terminal should be properly recognized by other terminals. If the size is too small, the recognition rate is easily lowered. If the size is too large, the color block matrix occupies the whole screen, the screen flicker feeling is too strong, and the user experience is not good. Therefore, the size of a single color block can be controlled to be about 5mm × 5 mm.

In step 204, the display terminal displays the colors indicated by the color sequences corresponding to the information codes in the information code set in the first color patch matrix according to a pre-stored relationship table.

In this embodiment, the display terminal may display, in the first color patch matrix, the color indicated by the color sequence corresponding to each information code in the information code set according to a pre-stored relationship table. Wherein, the relation table stores the digital code in the code and the color information corresponding to the digital code. Here, the relationship table may be obtained from the server or another server in advance and stored locally, or may be manually stored in advance therein. In order to increase the identifiability of the first color block matrix and improve the anti-interference performance of the identification system, a color with a larger distinction degree can be adopted as the color corresponding to each digital code. By way of example, the relationship table may be as follows:

TABLE 1

Colour(s)	Red wine	Yellow colour	Green	Green leaf of Chinese cabbage	Blue (B)	Purple pigment	White colour (Bai)	Black colour
									Digital code	0	1	2	3	4	5	6	7

At this time, if the information codes in the information code set are 03 and 12, respectively, the colors indicated by the color sequence corresponding to the information code 03 are red and cyan in turn, and the colors indicated by the color sequence corresponding to the information code 12 are yellow and green in turn. In this way, the display terminal can display the color indicated by the color sequence corresponding to each information code in the first color block matrix in the manner shown in fig. 3a or fig. 3 b.

In fig. 3a, one information code may correspond to one row (or one column) of color blocks, and each color block in the row corresponds to one code in the information code. That is, the color patches of the first row display red and cyan, respectively, and the color patches of the second row display yellow and green, respectively.

In order to increase the number of information codes that can be conveyed by the first color patch matrix, as shown in fig. 3b, one information code may correspond to one color patch, and all colors indicated by the color sequence corresponding to the information code are displayed in the color patch. At this time, in order to improve the identifiability of the first color block matrix, the color blocks corresponding to the information codes in the same row may be arranged at intervals. I.e. red and cyan are shown in the color blocks located in row 1, column 1. Yellow and green are shown in the color blocks located in row 1, column 3.

In some optional implementations of this embodiment, in order to further increase the number of information codes that can be conveyed by the first color block matrix, for each information code in the information code set, the color indicated by the color sequence corresponding to the information code may be displayed cyclically in the same color block in the first color block matrix. As shown in fig. 3c, one information code may correspond to one color patch, and the color indicated by the color sequence corresponding to the information code is displayed in a loop in the color patch. At this time, in order to determine the start number and the end number of the information code to improve the identifiability of the first color patch matrix, each color patch may not display any color or display colors not stored in the relational table after displaying all colors indicated by the color sequence once. That is, for the information code 03, the color blocks in the first row and the first column are displayed circularly according to the sequence of red, cyan and blank; for the information code 12, the color blocks in the first row and the second column are displayed circularly in the order of yellow, green and blank. In addition, compared with the static display mode in fig. 3a and 3b, the first color block matrix in fig. 3c adopts a dynamic display mode, so that the first color block matrix is not easily copied from the display terminal to other devices, and the reliability of information transmission can be improved. Even if the first color block matrix is copied to other equipment, after the server updates the encoding file, the information encoding set corresponding to the information to be transmitted stored in the server changes. At this time, the first color block matrix displaying the color indicated by the color sequence corresponding to the information code in the information code set is also changed, so that the copied first color block matrix is also invalid. This can further improve the reliability of information transmission.

It is understood that the time for displaying the colors in the same color block alternately can be set according to actual conditions. But if the time is too short, the screen refresh rate is not sufficient, resulting in errors. And if the time is too long, the communication rate is too slow and the user experience is degraded. The time can be set generally between 20-100 milliseconds. In addition, in order to facilitate the synchronous display of each color block, if the digits of the numbers in each information code are different, 0 can be supplemented after the information code with less digits, so that the digits of the numbers in each information code are the same.

In some optional implementation manners of the present embodiment, the display terminal may further display a color indicated by a color sequence corresponding to each information code in the information code set by the following steps.

1) And acquiring synchronous codes.

The sync code may be preset and stored in the display terminal. The display terminal can acquire the synchronous codes from the local. The synchronization code may be generated by the server when encoding information to be transmitted, and may be transmitted to the display terminal by the server. The synchronous codes may also be (but are not limited to) binary codes, and are used to determine the start numbers and the end numbers of each information code in the information code set, where the number of digits of the number may be the same as (or different from) the number of digits in the information code, but it is sufficient to ensure that the corresponding color information can be found in the relationship table by the digits in the synchronous codes. It will be appreciated that since the synchronization code may be used to determine the start and end codes of the information code, the synchronization code is different from each of the information codes in the information code set, i.e., the same information code as the synchronization code cannot be present in the information code set.

2) A second color block matrix is generated based on the information encoding set and the synchronization encoding.

The display terminal can generate the second color block matrix according to the number of the information codes in the information code set and the preset number of the synchronous codes. The preset number of sync codes may be any positive integer. For example, if the information code set includes 3 information codes and the preset number of synchronous codes is 1, a row and four columns of the second color block matrix can be generated. For a specific generation process, refer to step 203, which is not described herein again. In the second color block matrix, the color blocks corresponding to the synchronous codes are synchronous color blocks, and the color blocks corresponding to each information code in the information code set are information color blocks. It should be noted that the position of the sync block in the second color block matrix is not limited in this application. To increase the communication rate, the patch located at the first column of the first row (or the last column of the last row) may be set as a sync patch.

3) And according to the relation table, circularly displaying the colors indicated by the corresponding color sequences in the synchronous color blocks, and circularly displaying the colors indicated by the corresponding color sequences in each information color block.

The display terminal may also cyclically display (i.e., dynamically display) the colors indicated by the color sequence corresponding to the sync codes in each sync tile and cyclically display (i.e., dynamically display) the colors indicated by the color sequence corresponding to the information codes in each information tile according to the relationship table. At this time, since the start number and the end number of the information code can be determined by the sync code, the display period of the sync patch can be used to represent the display period of the information patch. That is, when the sync patches display the color corresponding to the start number (or the end number) in the sync code, the information patches also display the color corresponding to the start number (or the end number) in the information code. It is understood that, in order to simplify the display process, the number of digits in the synchronization code may be the same as the number of digits in the information code, and the synchronization color block and the information color block have the same update frequency (time for alternately displaying colors).

Optionally, when the number of information codes in the information code set is greater than a preset value, there may be a preset number of synchronized color blocks in the second color block matrix. And the area formed by the preset number of synchronous color blocks is used for representing the area of the second color block matrix. As an example, when a line of the display screen can display 5 color patches, if the number of information codes (i.e., the number of information color patches) n satisfies: n is more than or equal to 1 and less than or equal to 3 (namely the row number of the second color block matrix is 1), and the second color block matrix can have 2 synchronous color blocks. At this time, as shown in fig. 4a, sync patches (shaded patches in the figure) may be respectively located in the first row and the first column and the last column of the first row. If n satisfies: n is greater than or equal to 4 (i.e., the number of rows in the second color block matrix is greater than or equal to 2), and there may be at least 3 sync blocks in the second color block matrix. The specific positions of the sync patches (shaded patches in the figure) can be seen as (1), (2) and (3) in fig. 4 b. It should be noted that, when the number of rows of the second color block matrix is 2, as shown in fig. 4b (1), the sync blocks located in the first row and the first column are adjacent to each other, which is not favorable for detecting the sync blocks. Therefore, in order to improve the communication efficiency, the number of rows of the second color block matrix may be set to be different from 2 in advance.

In step 205, the scanning terminal scans the first color block matrix and generates a first information encoding set according to the relationship table.

In this embodiment, a scanning terminal (for example, the scanning terminal 102 shown in fig. 1) may scan the first color patch matrix displayed on the display terminal after receiving a prompt message sent by the server or detecting an instruction for instructing to capture an image (for example, detecting that a camera is turned on). The prompt information is used for prompting a user to hold the scanning terminal to do a specified action. For example, the prompt message may be "please scan a pattern on the screen of the display terminal". It is understood that, in order to avoid information omission, the scanning terminal should ensure that the entire first color block matrix is scanned when scanning the display screen of the display terminal.

In this embodiment, the relationship table may also be stored in the scanning terminal in advance. And the scanning terminal can determine the number corresponding to each displayed color according to the color information corresponding to the number in the relation table while scanning the first color block matrix. And determining the sequence of the corresponding digital codes according to the sequence displayed by each color to generate a first information code, and further generating a first information code set. The specific process may refer to step 204, which is opposite to the display process of the first color block matrix and is not described herein again.

In some optional implementation manners of this embodiment, the scanning terminal may further determine, through the following steps, an information encoding set corresponding to a color displayed in a color block matrix on the display terminal.

1) And acquiring synchronous codes.

The process of acquiring the synchronization code by the scanning terminal may refer to the description of the display terminal acquiring the synchronization code in step 204, which is not described herein again. The synchronization coding here is the same as the above-described synchronization coding.

2) The sync blocks in the second color block matrix are determined based on the sync code and the relationship list.

After the synchronous codes are obtained, the scanning terminal can determine the color information corresponding to the digital codes in the synchronous codes according to the relation table. And when the second color block matrix is scanned, the color blocks with the same colors and the same sequence as those indicated by the color sequence corresponding to the synchronous codes are the synchronous color blocks. In addition, in order to improve the reliability of the identification, the scanning terminal may determine the patch as a synchronous patch after continuously detecting a preset number of times (e.g., 2 times).

3) And determining a starting color and an ending color in the colors indicated by the color sequences displayed in the information color blocks according to the display period of the synchronous color blocks, and generating a second information coding set according to the relation list.

After the synchronous color blocks are determined, the scanning terminal can determine the starting color and the ending color in the colors indicated by the color sequences displayed in the information color blocks according to the display period of the synchronous color blocks. And further, according to the relation table, the number and the sequence corresponding to the color indicated by the color sequence can be determined, and the second information code is generated, so that the second information code set is generated.

4) And sending the second information coding set to a server so that the server sends the information to be sent to the scanning terminal after determining that the second information coding set is matched with the information coding set.

The scanning terminal may transmit the generated second information code set to the server. In this way, the server may send the information to be sent to the scanning terminal when determining that each second information code in the second information code set is the same as each information code in the information code set.

It can be understood that, when the second color block matrix includes a predetermined number of synchronized color blocks, the scanning terminal can also determine the predetermined number of synchronized color blocks. That is, a preset number of synchronized color patches in the second color patch matrix is determined according to the synchronization code and the relationship list. At this time, since the region of the second color block matrix can be determined according to the regions formed by the preset number of synchronous color blocks, the scanning terminal can determine the position and the shape of each information color block by an affine transformation method according to the position and the shape of the preset number of synchronous color blocks. Therefore, the problem of information omission when the scanning terminal scans the second color block matrix can be prevented.

It should be noted that, during scanning, the scanning terminal often does not scan right against the display screen of the display terminal, so that the scanning terminal is generally inclined. This results in that the color blocks obtained by the scanning terminal are not necessarily the shapes displayed on the display terminal, so that the scanning terminal can restore the shapes of the color blocks according to the affine transformation method, thereby determining the accurate positions of the information color blocks. The affine transformation method is prior art and will not be described in detail here.

In step 206, the scanning terminal sends the first encoded set of information to the server.

In this embodiment, the scanning terminal may send the first information encoding set generated in step 205 to the server through a wired connection manner or a wireless connection manner.

In step 207, the server sends the information to be sent to the scanning terminal after determining that the first information encoding set matches the information encoding set.

In this embodiment, the server may compare the first information encoding set with the information encoding set after receiving the first information encoding set. If each first information code in the first information code set is the same as each information code in the information code set, it can be determined that the first information code set matches the information code set. At this time, the server may send information to be sent corresponding to the information coding set to the scanning terminal.

It should be noted that, if the preset number of times of use set on the server is 1, the server updates the encoded file after receiving the first information encoding set matching the currently stored information encoding set for the first time. At this time, the server generates an information code set according to the updated code file and sends the information code set to the display terminal. In this way, the server may determine whether the scanning terminal is a first encoded set of information generated by scanning a first color patch matrix on the display terminal.

The information transmission system provided by the embodiment of the application firstly encodes each character in the information to be transmitted respectively through the server to generate an information encoding set, and transmits the information encoding set to the display terminal; then the display terminal displays colors indicated by color sequences corresponding to all information codes in the information code set in a first color block matrix generated based on the information code set according to a pre-stored relation table; then, when scanning the first color block matrix, the scanning terminal generates a first information coding set according to the relation table and sends the first information coding set to the server; and finally, after determining that the first information coding set is matched with the information coding set, the server sends the information to be sent to the scanning terminal, so that the reliability of information transmission can be improved.

With further reference to fig. 5, a schematic diagram of an application scenario of the information transmission system provided in the present application is shown.

As shown in fig. 5, in the application scenario, an instant messenger is installed on both a display terminal 51 used by a user a and a scanning terminal 52 used by a user B, and the user a and the user B can become friends by adding accounts on the instant messenger. The account number of the user A is W. At this time, the server 53 may encode information to be transmitted (i.e., the account number W), generate an information encoding set (01, 12), and transmit it to the display terminal 51. The information code corresponding to the character W is 01, and the information code corresponding to the character is 12. The display terminal 51 generates a color block matrix from the information encoding set (01, 12) and the synchronization encoding (31). And displaying the colors indicated by the corresponding color sequences in the color lump matrixes according to the relation list. At this time, the user B may turn on the camera on the scanning terminal 52 and scan the color patch matrix on the display screen of the display terminal 51. The scanning terminal 52 may first find the positions of the synchronized color patches according to the relationship table and the synchronization code, thereby determining the positions of the color patch matrix. Then, according to the display rule of the synchronous codes, the starting color and the ending color in the information color blocks are determined, and a second information code set (01, 12) is generated according to the relation table. The scanning terminal 52 sends the second encoded set of information to the server 53. After determining that the second information code set (01, 12) matches the information code set (01, 12) generated before, the server 53 transmits the information to be transmitted (i.e., the account W of the user a) to the scanning terminal 52. Thus, user B may add user a as a buddy by scanning the information received by terminal 52.

With continued reference to fig. 6, a flow 600 of one embodiment of an information transfer method provided herein is shown. The process 600 of the information transmission method includes the following steps:

step 601, receiving an information coding set sent by a server.

In this embodiment, the electronic device (for example, the display terminal 101 shown in fig. 1) on which the information transmission method operates may receive the information encoding set sent by the server (for example, the server 104 shown in fig. 1) through a wired connection manner or a wireless connection manner. The information coding set is generated by the server by coding each character in the information to be transmitted respectively and corresponds to the information to be transmitted. For a specific process, reference may be made to related descriptions in step 201 and step 202 shown in fig. 2, and details are not described here.

Step 602, a first color block matrix is generated based on the number of information codes in the information code set.

In this embodiment, based on the information encoding set received in step 601, the electronic device may generate a first color block matrix according to the number of information encodings in the information encoding set. Specifically, reference may be made to the related description in step 203 shown in fig. 2, and details are not described here.

Step 603, displaying the color indicated by the color sequence corresponding to each information code in the information code set in the first color block matrix according to a pre-stored relation table.

In this embodiment, the electronic device may determine, according to the relationship table, a color indicated by a color sequence corresponding to each information code in the information code set, and display the color in the first color block matrix. Further, the scanning terminal (e.g., the scanning terminal 102 shown in fig. 1) may scan the first color patch matrix, generate a first information encoding set according to the relationship table, and transmit the first information encoding set to the server (e.g., the server 104 shown in fig. 1). And after determining that the first information coding set is matched with the information coding set, the server can send the information to be sent to the scanning terminal. Wherein, the relation table stores the digital code in the code and the color information corresponding to the digital code. Specifically, reference may be made to the related descriptions in step 204 to step 207 shown in fig. 2, which are not described herein again.

In some optional implementations of this embodiment, for each information encoding in the set of information encodings, the color indicated by the color sequence corresponding to that information encoding may be displayed cyclically in the same color patch in the first color patch matrix.

In some optional implementation manners of this embodiment, the method may further include: acquiring a synchronous code, wherein the synchronous code is different from each information code in the information code set; generating a second color block matrix based on the information coding set and the synchronous codes, wherein in the second color block matrix, color blocks corresponding to the synchronous codes are synchronous color blocks, and color blocks corresponding to each information code in the information coding set are information color blocks; and according to the relation table, circularly displaying the colors indicated by the corresponding color sequences in the synchronous color blocks, and circularly displaying the colors indicated by the corresponding color sequences in each information color block, wherein the display period of the synchronous color blocks is used for representing the display period of the information color blocks.

In some optional implementations of this embodiment, when the number of information codes in the information code set is greater than a preset value, there are a preset number of synchronized color blocks in the second color block matrix, where a region formed by the preset number of synchronized color blocks is used to represent a region where the second color block matrix is located.

In the information transmission method provided by the embodiment of the application, the information to be sent is converted into the information coding set corresponding to the information to be sent, and the color information corresponding to the digital code is found in the relation table according to the digital code in each information code in the information coding set, so that the color sequence corresponding to each information code is determined, and the color indicated by the color information in the color sequence is displayed in the generated first color block matrix. That is, the information to be transmitted is converted into the information code for transmission, so that the reliability of information transmission can be improved. Meanwhile, information coding is transmitted through the color block matrix, so that the risk of information leakage can be reduced, and the safety of information transmission is improved. In addition, the dynamic display of colors can be performed through the color block matrix, so that compared with the traditional static display mode of bar codes or two-dimensional codes, the content of the color block matrix is not easy to copy to other equipment. And the copied color block matrix is often invalid, so that the information to be sent can be obtained only after the scanning terminal scans the color block matrix displayed on the display terminal and sends the obtained information code to the server, and the reliability of information transmission can be further improved.

With further reference to fig. 7, the present application provides one embodiment of an information transfer device as an implementation of the method illustrated in fig. 6 above.

Referring further to fig. 9, a flow 900 of yet another embodiment of an information transmission method provided herein is shown. The process 900 of the information transmission method includes the following steps:

step 901, scanning a first color block matrix displayed on a display terminal.

In this embodiment, an electronic device (for example, the scanning terminal 102 shown in fig. 1) on which the information transmission method operates may scan a first color patch matrix displayed on a display terminal (for example, the display terminal 101 shown in fig. 1) through a camera. The color sequence displayed in the first color block matrix is used for representing the information codes in the information code set. And the information coding set is an information coding set which is generated by respectively coding each character in the information to be transmitted and corresponds to the information to be transmitted. Here, the encoding process may be performed by the display terminal; the information may be transmitted to the display terminal after the server (e.g., the server 104 shown in fig. 1) is completed. For a specific process, reference may be made to the related descriptions in step 201 to step 204 shown in fig. 2, which are not described herein again.

In this embodiment, the electronic device may determine a number corresponding to each displayed color according to a pre-selected stored relationship table, thereby generating the first information encoding set. Wherein, the relation table stores the digital code in the code and the color information corresponding to the digital code. For a specific process, reference may be made to the related description in step 205 shown in fig. 2, and details are not described here.

Step 903, obtaining the information to be sent based on the first information coding set.

In this embodiment, the electronic device may send the generated first information encoding set to a display terminal or a server. Therefore, after the display terminal or the server determines that the first information code set is matched with the stored information code set, the information to be sent can be sent to the electronic equipment. For a specific process, reference may be made to related descriptions in step 206 and step 207 shown in fig. 2, and details are not described here.

As an example, the electronic device may further store an encoding file thereon in advance. The encoding file is the same as the encoding files in the above embodiments, and is used for the corresponding relationship between characters and codes. At this time, the electronic device may determine, according to the encoded file and the first information encoding set, a character corresponding to each information encoding, thereby obtaining the information to be transmitted.
