Fig. 1 is a schematic flowchart of a two-dimensional code processing method according to an embodiment of the present application. Referring to fig. 1, an embodiment of the present application provides a two-dimensional code processing method, which may include:
step 110, separating color channels of the first two-dimensional code image, and determining an arrangement rule corresponding to the separated first color channels according to predetermined information;

wherein the predetermined information includes any one of:
identification information of the first terminal;
identification information, unified clock information and a preset time window of the second terminal; the unified clock is a clock shared by the first terminal and the second terminal.
It should be noted that an execution main body of the two-dimensional code processing method provided in the embodiment of the present application may be a first terminal. The first terminal may be an intelligent electronic device, such as a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like. The second terminal and the first terminal may be the same type of terminal, for example, the second terminal and the first terminal may both be mobile phones. The second terminal and the first terminal may also be different types of terminals, for example, the second terminal may be a PC and the first terminal may be a handset.
An application scenario of the two-dimensional code processing method provided by the embodiment of the present application may be, for example, a scenario in which the first terminal and the second terminal perform remote assistance: the first terminal can be used as an assisted party to accept the assistance of the second terminal. In this scenario, the first terminal may process the first two-dimensional code according to the two-dimensional code processing method provided by the embodiment of the present application, and then send the second two-dimensional code to the second terminal.
Of course, the two-dimensional code processing method provided in the embodiment of the present application may also be applicable to other application scenarios, which are not listed here.
The first terminal may first recognize whether the two-dimensional code exists in the currently transmitted image.
If the first terminal does not recognize that the image contains the two-dimensional code, the first terminal can normally send the image.
If the first terminal identifies that the image contains the two-dimensional code, the first terminal intercepts the first two-dimensional code image from the image and separates a color channel of the first two-dimensional code image from the first two-dimensional code image. The first two-dimensional code image may be an original two-dimensional code image.
After separating the color channels of the first two-dimensional code image, the first terminal may determine an arrangement rule corresponding to the first color channel according to predetermined information.
For example, the first terminal may determine an arrangement rule corresponding to the first color channel according to the identification information of the first terminal; or the first terminal may determine the arrangement rule corresponding to the first color channel according to the identification information of the second terminal, the unified clock information, and the preset time window.
The first terminal may process the first color channel according to an arrangement rule corresponding to the first color channel to obtain a second color channel.
After obtaining the second color channel, the first terminal may re-synthesize the second two-dimensional code image according to the second color channel.
After the second two-dimensional code image is obtained, the first terminal sends the second two-dimensional code image to the second terminal.
It should be noted that, since the first terminal processes the color channel of the first two-dimensional code image to obtain the second two-dimensional code image, the second two-dimensional code image is significantly different from the first two-dimensional code image, as shown in fig. 2. Under the condition that the arrangement rule of the color channels is not known, the third party cannot restore the second two-dimensional code image into the first two-dimensional code image, so that the information of the first two-dimensional code cannot be acquired.
According to the two-dimensional code processing method, the color channels of the first two-dimensional code image are processed according to the corresponding arrangement rules, the second two-dimensional code image is synthesized according to the processed color channels and sent, encrypted transmission of the first two-dimensional code information can be achieved, safety risks caused by two-dimensional code information leakage are avoided, and the safety of two-dimensional code transmission is improved.
In an embodiment, in a case that the predetermined information includes identification information of the first terminal, the two-dimensional code processing method provided in the embodiment of the present application may further include:
and sending the arrangement rule corresponding to the first color channel to the second terminal.
After the first terminal obtains the second color channel according to the arrangement rule corresponding to the first color channel and determines the second two-dimensional code image according to the second color channel, the first terminal may send the arrangement rule corresponding to the first color channel to the second terminal.
For example, the first terminal may send the arrangement rule corresponding to the first color channel to the second terminal when sending the second two-dimensional code to the second terminal. The first terminal may also send the arrangement rule corresponding to the first color channel to the second terminal after sending the second two-dimensional code to the second terminal.
For example, the first terminal may send the arrangement rule corresponding to the first color channel to the second terminal through a separate message, encrypted or not encrypted.
The present application does not specifically limit the transmission timing and the transmission manner of the arrangement rule corresponding to the first color channel.
After receiving the arrangement rule corresponding to the first color channel sent by the first terminal, the second terminal can perform reverse processing on the received second two-dimensional code image according to the arrangement rule corresponding to the first color channel to restore and obtain the first two-dimensional code image, and thus perform operations such as remote assistance according to the first two-dimensional code image.
According to the two-dimensional code processing method provided by the embodiment of the application, the arrangement rule corresponding to the first color channel is sent to the second terminal under the condition that the arrangement rule corresponding to each color channel is determined according to the identification information of the first terminal, so that the second terminal can restore the first two-dimensional code image according to the arrangement rule corresponding to the first color channel, and smooth operation such as remote assistance is guaranteed.
It should be noted that, for the color channel of the two-dimensional code, it may generally be composed of RGB three-color sub-channels, that is, the color channel of the two-dimensional code may be specifically divided into a red sub-channel, a green sub-channel, and a blue sub-channel.
In one embodiment, the ranking rules may include at least one of:
the arrangement rule A is used for adjusting the gray value of each pixel in the color sub-channel;
for example, the gray scale value for a pixel in the red sub-channel may be represented as R (x, y), and the adjusted gray scale value for the pixel may be represented as R (x, y)

Then:
Figure BDA0003225195890000072
wherein x is the abscissa of the pixel; y is the ordinate of the pixel; 255 is a preset grey value; max (r) represents the maximum of the gray values for each pixel in the red subchannel.
It can be seen from the formula (1) that adjusting the gray value of each pixel in the color sub-channel may be selecting a smaller value from the preset gray value and the maximum value of the gray value of each pixel, and subtracting the smaller value from the gray value of the pixel to obtain the gray value of the pixel after adjustment. The specific size of the preset gray value may be adjusted according to an actual situation, which is not specifically limited in the embodiment of the present application.
The adjustment rule of the gray scale values of the pixels in the other color sub-channels is the same as that described above, and is not described herein again.
The arrangement rule B is used for translating the gray values of at least part of pixels in the color sub-channels according to the abscissa of the pixels;
for example, the gray scale value for a pixel in the red sub-channel may be represented as R (x, y), and the gray scale value for the pixel after translation according to the abscissa may be represented as R (x, y)

Then:

wherein x is the abscissa of the pixel; y is the ordinate of the pixel; w is the width of the first two-dimensional code; w is a0Is an initial random value, and w0∈[0,w]。
As shown in formula (2), rule B is to shift the gray-level values of at least some pixels according to the abscissa of the pixels, i.e., shift the gray-level values of the original pixels to other pixels along the horizontal axis. Wherein the specific number of the partial pixels is determined by the width w of the first two-dimensional code and the initial random value w0And (4) determining. InitialRandom value w0The specific size of the optical fiber can be adjusted according to actual needs, which is not specifically limited in the embodiment of the present application.
And C, translating the gray values of at least part of pixels in the color sub-channels according to the ordinate of the pixels.
For example, the gray scale value for a pixel in the red sub-channel may be represented as R (x, y), and the gray scale value of the pixel after translation according to the ordinate may be represented as R (x, y)
Figure BDA0003225195890000081
Then:
Figure BDA0003225195890000082
wherein x is the abscissa of the pixel; y is the ordinate of the pixel; h is the height of the first two-dimensional code; h is0Is an initial random value, and h0∈[0,h]。
As shown in formula (3), rule C is to shift the gray-level values of at least some pixels according to the ordinate of the pixels, i.e., shift the gray-level values of the original pixels to other pixels along the ordinate. Wherein the specific number of the partial pixels is determined by the height h of the first two-dimensional code and the initial random value h0And (4) determining. Initial random value h0The specific size of the optical fiber can be adjusted according to actual needs, which is not specifically limited in the embodiment of the present application.
The above arrangement rules may be arbitrarily combined. For example, combining rule B with rule C, one can derive rule B + C:
translating the gray values of at least part of pixels in the color sub-channels according to the abscissa and the ordinate of the pixels;
for example, the gray scale value for a pixel in the red sub-channel may be represented as R (x, y), and the gray scale value for the pixel translated according to the abscissa and the ordinate may be represented as R (x, y)
Figure BDA0003225195890000083
Then:
Figure BDA0003225195890000084
wherein x is the abscissa of the pixel; y is the ordinate of the pixel; w is the width of the first two-dimensional code; w is a0Is an initial random value, and w0∈[0,w](ii) a h is the height of the first two-dimensional code; h is0Is an initial random value, and h0∈[0,h]。
As shown in formula (4), the rule B + C is to translate the gray scale value of at least some pixels according to the ordinate and abscissa of the pixel, that is, to translate the gray scale value of the original pixel to other pixels along the abscissa and the ordinate.
In an embodiment, in a case that the predetermined information includes identification information of the first terminal, determining an arrangement rule corresponding to the separated first color channel according to the predetermined information may include:
determining an arrangement rule of the first color sub-channel according to the identification information of the first terminal;
determining an arrangement rule of a second color sub-channel according to an arrangement rule of the first color sub-channel;
determining an arrangement rule of a third color sub-channel according to the arrangement rule of the second color sub-channel;
the first color channel comprises a first color sub-channel, a second color sub-channel and a third color sub-channel, and the first color sub-channel, the second color sub-channel and the third color channel respectively correspond to one of a red sub-channel, a green sub-channel and a blue sub-channel and are different from each other.
For example, the first color sub-channel may be a red sub-channel, the second color sub-channel may be a green sub-channel, and the third color sub-channel may be a blue sub-channel.
Assuming that the arrangement rule of the red sub-channels is result, then:
result＝hashCode(deviceID)modN+1 (5)
wherein, the hashCode is a hash coding function; deviceID is the ID of the first terminal; modN is a corresponding relation function of the hash coding function value and the arrangement rule number.
As can be seen from equation (5), the ID of the first terminal may be first input into the hash coding function to determine the hash coding function value of the first terminal; then, a corresponding arrangement rule number N can be determined according to the hash coding function value; and finally, the arrangement rule of the red sub-channel is the arrangement rule corresponding to the arrangement rule number N + 1.
Wherein modN can be as shown in the following table:
TABLE 1 one of tables of correspondence between hash-coding function values and arrangement rule numbers
hashCode(deviceID) Rule numbering
0≤hashCode(deviceID)<10 0,4,8,…
10≤hashCode(deviceID)<20 1,5,…
20≤hashCode(deviceID)<30 2,6,…
hashCode(deviceID)≥30 3,7,…
Wherein, the arrangement rule a may correspond to rule numbers 1,5, …; the arrangement rule B may correspond to rule numbers 2,6, …; the arrangement rule C may correspond to rule numbers 3,7, …; the arrangement rule B + C may correspond to rule numbers 4,8, ….
For example, when the first terminal ID is 888888, the hash coding function value of the first terminal ID is 1 by calculating the first terminal ID through the hash coding function, N is determined to be 0 by the corresponding relation function modN between the hash coding function value and the arrangement rule number, and the arrangement rule of the red sub-channel is an arrangement rule corresponding to N +1 ═ 1, that is, the gray scale value of each pixel in the red sub-channel is adjusted according to the arrangement rule a.
After the arrangement rule of the red sub-channel is determined, the arrangement rule number of the green sub-channel can be determined according to the arrangement rule number of the red sub-channel. For example, the arrangement rule number of the green sub-channel may be G ═ R + 1. Wherein, R is the arrangement rule number of the red subchannel.
After the arrangement rule of the green sub-channel is determined, the arrangement rule number of the blue sub-channel can be determined according to the arrangement rule number of the green sub-channel. For example, the arrangement rule number of the blue sub-channel may be B ═ G + 1.
Therefore, when the arrangement rule of the red sub-channel is numbered 1, the arrangement rule of the green sub-channel is numbered 2, and the arrangement rule of the blue sub-channel is numbered 3. According to the rule B, translating the gray values of at least part of pixels in the green sub-channel according to the abscissa of the pixels; and translating the gray values of at least part of pixels in the blue sub-channel according to the rule C according to the ordinate of the pixels.
According to the two-dimensional code processing method provided by the embodiment of the application, the arrangement rule of the first color sub-channel is determined according to the Hash coding function and the like based on the identification information of the first terminal, and then the arrangement rules of other color sub-channels are sequentially determined, so that the determination complexity of the arrangement rules of the color sub-channels can be effectively improved, the risk that a third party cracks the second two-dimensional code is reduced, and the safety of two-dimensional code processing is further improved.
In an embodiment, in a case that the predetermined information includes identification information of the second terminal, unified clock information, and a preset time window, determining, according to the predetermined information, an arrangement rule corresponding to the separated first color channel may include:
and determining an arrangement rule corresponding to the first color channel according to the identification information of the second terminal, the unified clock information and the preset time window.
The unified clock and the preset time window shared by the first terminal and the second terminal may be preset, and then the method for determining the arrangement rule corresponding to the first color channel according to the identification information, the unified clock information and the preset time window of the second terminal, which are pre-stored, may be stored in the first terminal and the second terminal.
In this way, after the first terminal receives the identification information of the second terminal sent by the second terminal (or the first terminal may also store the identification information of the second terminal in advance), the first terminal and the second terminal both know the method for determining the arrangement rule corresponding to each color channel, and when the first terminal determines the arrangement rule corresponding to each color channel according to the one-time clock information, the second terminal can also synchronously determine the rule for restoring the first color channel, so as to restore the first two-dimensional code.
According to the two-dimensional code processing method provided by the embodiment of the application, the unified clock information shared by the first terminal and the second terminal is set, and the arrangement rule corresponding to the first color channel is determined according to the identification information and the unified clock information of the second terminal, so that the second terminal can synchronously determine the rule for restoring the first color channel, the restoration of the first two-dimensional code can be realized under the condition that the arrangement rule corresponding to the first color channel is not sent, and the transmission safety of the two-dimensional code is further improved.
On the basis of the foregoing embodiment, determining an arrangement rule corresponding to the first color channel according to the identification information of the second terminal, the unified clock information, and the preset time window may include:
determining a current timestamp according to the unified clock information;
determining an arrangement rule of the first color sub-channel according to the identification information of the second terminal, the current timestamp and a preset time window;
determining an arrangement rule of a second color sub-channel according to an arrangement rule of the first color sub-channel;
determining an arrangement rule of a third color sub-channel according to the arrangement rule of the second color sub-channel;
the first color channel comprises a first color sub-channel, a second color sub-channel and a third color sub-channel, and the first color sub-channel, the second color sub-channel and the third color sub-channel respectively correspond to one of a red color channel sub-channel, a green color sub-channel and a blue color sub-channel and are different from each other.
For example, the first color sub-channel may be a red sub-channel, the second color sub-channel may be a green sub-channel, and the third color sub-channel may be a blue sub-channel.
Assuming that the arrangement rule of the red sub-channels is result, then:
result＝hashCode(deviceID+nowTime/T)modN+1 (6)
wherein, the hashCode is a hash coding function; deviceID is the ID of the second terminal; nowTime is the current timestamp determined according to the unified clock information; t is a preset time window; modN is a corresponding relation function of the hash coding function value and the arrangement rule number.
As can be seen from the formula (6), the current timestamp can be determined according to the unified clock information, the remainder calculation is performed on the current timestamp according to the preset time window, and then the second terminal ID and the remainder calculation result are input into the hash coding function to determine the hash coding function value; it should be noted that the length of the time window T may be, for example, 30s (the specific size of the time window T is not specifically limited in the embodiment of the present application), and the value of nowTime/T is not changed within 30 s.
Then, the corresponding arrangement rule number N may be determined according to the hash encoding function value.
And finally, the arrangement rule of the red sub-channel is the arrangement rule corresponding to the arrangement rule number N + 1.
Wherein modN can be as shown in the following table:
TABLE 2 second table of correspondence between hash-coding function values and arrangement rule numbers
hashCode(deviceID+nowTime/T) Rule numbering
0≤hashCode(deviceID+nowTime/T)<10 0,4,8,…
10≤hashCode(deviceID+nowTime/T)<20 1,5,…
20≤hashCode(deviceID+nowTime/T)<30 2,6,…
hashCode(deviceID+nowTime/T)≥30 3,7,…
Wherein, the arrangement rule a may correspond to rule numbers 1,5, …; the arrangement rule B may correspond to rule numbers 2,6, …; the arrangement rule C may correspond to rule numbers 3,7, …; the arrangement rule B + C may correspond to rule numbers 4,8, ….
For example, when the sum of the first terminal ID and the remainder calculation result is calculated by the hash coding function to obtain a hash coding function value of 1, N may be determined to be 0 by the corresponding relation function modN between the hash coding function value and the arrangement rule number, and the arrangement rule of the red sub-channel is an arrangement rule corresponding to N +1 ═ 1, that is, the gray scale value of each pixel in the red sub-channel is adjusted according to the arrangement rule a.
After the arrangement rule of the red sub-channel is determined, the arrangement rule number of the green sub-channel can be determined according to the arrangement rule number of the red sub-channel. For example, the arrangement rule number of the green sub-channel may be G ═ R + 1. Wherein, R is the arrangement rule number of the red subchannel.
After the arrangement rule of the green sub-channel is determined, the arrangement rule number of the blue sub-channel can be determined according to the arrangement rule number of the green sub-channel. For example, the arrangement rule number of the blue sub-channel may be B ═ G + 1.
Therefore, when the arrangement rule of the red sub-channel is numbered 1, the arrangement rule of the green sub-channel is numbered 2, and the arrangement rule of the blue sub-channel is numbered 3.

step 320, decoding the second two-dimensional code image according to the reverse arrangement rule of the first color channel to obtain a first two-dimensional code corresponding to the second two-dimensional code;
and displaying the first two-dimensional code image.
It should be noted that an execution main body of the two-dimensional code processing method provided in the embodiment of the present application may be a second terminal.

The second terminal and the first terminal may be the same type of terminal, for example, the second terminal and the first terminal may both be mobile phones. The second terminal and the first terminal may also be different types of terminals, for example, the second terminal may be a PC and the first terminal may be a handset.
An application scenario of the two-dimensional code processing method provided by the embodiment of the present application may be, for example, a scenario in which the first terminal and the second terminal perform remote assistance: the first terminal can be used as an assisted party to accept the assistance of the second terminal. In this scenario, the first terminal may process the first two-dimensional code according to the two-dimensional code processing method provided by the embodiment of the present application, and then send the second two-dimensional code to the second terminal.
Of course, the two-dimensional code processing method provided in the embodiment of the present application may also be applicable to other application scenarios, which are not listed here.
The second terminal can receive the second two-dimensional code image sent by the first terminal and the arrangement rule corresponding to the first color channel.
The second two-dimensional code image is determined by the first terminal according to the arrangement rule corresponding to the first color channel of the first two-dimensional code image and the arrangement rule corresponding to the first color channel.
Wherein the predetermined information may include any one of:
identification information of the first terminal;
identification information, unified clock information and a preset time window of the second terminal; the unified clock is a clock shared by the first terminal and the second terminal.
The specific method for determining the second two-dimensional code image by the first terminal may refer to the method embodiments described above, and details are not repeated here.
After the first terminal processes the first color channel according to the arrangement rule corresponding to each color channel to determine the second two-dimensional code image, the first terminal may send the arrangement rule corresponding to the first color channel to the second terminal, and the second terminal may receive the arrangement rule corresponding to the first color channel sent by the first terminal.
For example, the second terminal may receive the second two-dimensional code sent by the first terminal and receive the arrangement rule corresponding to the first color channel. The second terminal may also receive the arrangement rule corresponding to the first color channel sent by the first terminal after receiving the second two-dimensional code sent by the first terminal.
For example, the second terminal may receive a single encrypted or unencrypted message sent by the first terminal, and then parse the arrangement rule corresponding to the first color channel from the message.
The receiving time and the receiving mode of the arrangement rule corresponding to the first color channel are not particularly limited.
After receiving the arrangement rule corresponding to the first color channel sent by the first terminal, the second terminal can determine the reverse arrangement rule of the first color channel according to the arrangement rule corresponding to the first color channel.
For example, when the arrangement rule of the red sub-channel in the first color channel is the arrangement rule B + C, after the second terminal receives the arrangement rule corresponding to the red sub-channel sent by the first terminal, it may be determined that the reverse arrangement rule of the corresponding red sub-channel is
Figure BDA0003225195890000141
After the second terminal determines the reverse arrangement rule of the first color channel, the second two-dimensional code image can be decoded according to the determined reverse arrangement rule of the first color channel, so that the first two-dimensional code corresponding to the second two-dimensional code is obtained.
According to the two-dimensional code processing method provided by the embodiment of the application, the arrangement rule corresponding to the first color channel is received under the condition that the arrangement rule corresponding to the first color channel is determined according to the identification information of the first terminal, so that the second terminal can restore the first two-dimensional code image according to the arrangement rule corresponding to the first color channel, and smooth operation such as remote assistance is guaranteed.
Optionally, the second terminal sends the identification information of the second terminal to the first terminal under the condition that the first terminal determines the arrangement rule corresponding to the first color channel of the first two-dimensional code image according to the identification information of the second terminal, the unified clock information and the preset time window.
In this case, a unified clock and a preset time window shared by the first terminal and the second terminal may be preset, and then the first terminal and the second terminal may store a method of determining an arrangement rule corresponding to the first color channel according to the identification information of the second terminal, the unified clock information, and the preset time window. Therefore, the first terminal and the second terminal both know the method for determining the arrangement rule corresponding to the first color channel, and when the first terminal determines the arrangement rule corresponding to each color channel according to the one-time clock information, the second terminal can also synchronously determine the rule for restoring the first color channel, so that the first two-dimensional code is restored.
For example, when the first terminal determines that the arrangement rule of the red sub-channel is the arrangement rule B through the identification information, the unified clock information, and the preset time window of the second terminal, the second terminal may also determine that the arrangement rule of the red sub-channel is B through the identification information, the unified clock information, and the preset time window of the second terminal, so as to determine the reverse arrangement rule of the corresponding red sub-channel

Then, the second terminal may decode the second two-dimensional code image according to the determined reverse arrangement rule of the first color channel to obtain a first two-dimensional code corresponding to the second two-dimensional code.
According to the two-dimensional code processing method provided by the embodiment of the application, the identification information of the second terminal is sent to the first terminal, so that the first terminal determines the arrangement rule corresponding to the first color channel according to the identification information of the second terminal, the unified clock information and the preset time window, the second terminal can synchronously determine the rule for restoring the first color channel, the restoration of the first two-dimensional code can be realized under the condition that the arrangement rule corresponding to the first color channel is not sent, and the transmission safety of the two-dimensional code is further improved.
After the second two-dimensional code is restored according to the reverse arrangement rule of the first color channel to obtain the first two-dimensional code, the second terminal can display the first two-dimensional code image.
