All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

The method, the device and the electronic equipment for processing the two-dimensional code provided by the embodiment of the application are described in detail through specific embodiments and application scenes thereof with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart 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 the color channels of the first two-dimensional code image, and determining an arrangement rule corresponding to the separated first color channels according to preset information;
step 120, arranging the color channels according to the arrangement rule corresponding to the first color channel to obtain a second color channel;
step 130, synthesizing a second two-dimensional code image according to the second color channel;
step 140, sending the second two-dimensional code image to a second terminal;
wherein the predetermined information includes any one of:
identification information of the first terminal;
identification information of the second terminal, unified clock information and a preset time window; the unified clock is a clock shared by the first terminal and the second terminal.
It should be noted that, the execution body of the two-dimensional code processing method provided in the embodiment of the present application may be the first terminal. The first terminal may be an intelligent electronic device, such as a cell phone, tablet computer, notebook computer, palm computer, vehicle mounted electronic device, wearable device, ultra-mobile personal computer (UMPC), netbook or personal digital assistant (personal digital assistant, PDA), etc. The second terminal and the first terminal may be the same type of terminal, for example, the second terminal and the first terminal may be both mobile phones. The second terminal may also be a different type of terminal than the first terminal, for example the second terminal may be a PC and the first terminal may be a mobile phone.
The application scenario of the two-dimensional code processing method provided by the embodiment of the application may be, for example, a scenario in which the first terminal and the second terminal perform remote assistance: the first terminal may be assisted by the second terminal as an assisted party. In this scenario, the first terminal may process the first two-dimensional code according to the two-dimensional code processing method provided in 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 currently transmitted image has a two-dimensional code.
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 recognizes 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 channels 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, so as to obtain a second color channel.
After the second color channel is obtained, the first terminal can 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, a third party cannot restore the second two-dimensional code image to the first two-dimensional code image, so that the information of the first two-dimensional code cannot be obtained.
According to the two-dimensional code processing method, the color channels of the first two-dimensional code image are processed by adopting the corresponding arrangement rules, the second two-dimensional code image is synthesized according to the processed color channels to be sent, encryption 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 where 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 can send the arrangement rule corresponding to the first color channel to the second terminal.
For example, when the first terminal sends the second two-dimensional code to the second terminal, the first terminal may send the arrangement rule corresponding to the first color channel 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 encrypted or unencrypted message.
The transmission timing and the transmission 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 perform reverse processing on the received second two-dimensional code image according to the arrangement rule corresponding to the first color channel so as to restore the received second two-dimensional code image to obtain the first two-dimensional code image, thereby performing operations such as remote assistance and the like according to the first two-dimensional code image.
According to the two-dimensional code processing method, under the condition that the arrangement rule corresponding to each color channel is determined according to the identification information of the first terminal, the arrangement rule corresponding to the first color channel is sent to the second terminal, the second terminal can restore to obtain the first two-dimensional code image according to the arrangement rule corresponding to the first color channel, and therefore smooth operation such as remote assistance is guaranteed.
It should be noted that, for the color channel of the two-dimensional code, it may be generally 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 arrangement rules may include at least one of:
the arrangement rule A adjusts the gray value of each pixel in the color sub-channel;
for example, the gray value for a pixel in the red subchannel may be expressed as R (x, y), and the adjusted gray value for that pixel may be expressed as
Figure BDA0003225195890000071
Then:
Figure BDA0003225195890000072
wherein x is the abscissa of the pixel; y is the ordinate of the pixel; 255 is a preset gray value; max (R) represents the maximum value among the gradation values of the pixels in the red sub-channel.
As can be seen from the formula (1), the gray value of each pixel in the color sub-channel is adjusted by selecting a smaller value from the preset gray value and the maximum value of the gray values of each pixel, and subtracting the smaller value from the gray value of the pixel to obtain the adjusted gray value of the pixel. The specific size of the preset gray value can be adjusted according to actual situations, which is not particularly limited in the embodiment of the present application.
The adjustment rule of the gray values of the pixels in the other color sub-channels is the same as that described above, and will not be described here again.
Arranging rule B, translating gray values of at least part of pixels in the color sub-channels according to the abscissa of the pixels;
for example, the gray value for a pixel in the red subchannel may be expressed as R (x, y), and the gray value for the pixel translated according to the abscissa may be expressed as

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 (w) 0 Is an initial random value, and w 0 ∈[0,w]。
As can be seen from equation (2), rule B is to translate the gray value of at least some pixels according to the abscissa of the pixels, i.e. translate the gray value of the original pixel along the abscissa onto other pixels. Wherein the specific number of partial pixels is defined by the width w of the first two-dimensional code and the initial random value w 0 And (5) determining. Initial random value w 0 The specific size of (c) may be adjusted according to actual needs, which is not specifically limited in the embodiment of the present application.
And (3) arranging rule C, and translating gray values of at least part of pixels in the color sub-channels according to the ordinate of the pixels.
For example, the gray value for a pixel in the red subchannel may be expressed as R (x, y), and the gray value for the pixel translated according to the ordinate may be expressed as
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 is a 0 Is an initial random value, and h 0 ∈[0,h]。
From equation (3), it can be seen thatRule C is to translate the gray value of at least some pixels along the ordinate of the pixel, i.e. translate the gray value of the original pixel along the ordinate onto other pixels. Wherein the specific number of partial pixels is defined by the height h of the first two-dimensional code and the initial random value h 0 And (5) determining. Initial random value h 0 The specific size of (c) may be adjusted according to actual needs, which is not specifically limited in the embodiment of the present application.
It should be noted that the arrangement rules may be arbitrarily combined. For example, combining rule B with rule C, rule b+c may be derived:
translating 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 value for a pixel in the red subchannel may be expressed as R (x, y), and the gray value for the pixel translated according to the abscissa and ordinate may be expressed as
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 (w) 0 Is an initial random value, and w 0 ∈[0,w]The method comprises the steps of carrying out a first treatment on the surface of the h is the height of the first two-dimensional code; h is a 0 Is an initial random value, and h 0 ∈[0,h]。
As can be seen from equation (4), the rule b+c is to translate the gray value of at least some pixels according to the ordinate and the abscissa of the pixels, that is, translate the gray value of the original pixel to other pixels along the abscissa and the ordinate.
In one embodiment, in a case where the predetermined information includes identification information of the first terminal, determining, according to the predetermined information, an arrangement rule corresponding to the separated first color channel may include:
determining an arrangement rule of the first color sub-channels according to the identification information of the first terminal;
determining an arrangement rule of the second color sub-channels according to the arrangement rule of the first color sub-channels;
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 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 hashCode is a hash encoding function; the deviceID is the ID of the first terminal; modN is the corresponding relation function of the hash coding function value and the permutation rule number.
As can be seen from equation (5), the ID of the first terminal may be first input into the hash encoding function to determine the hash encoding function value of the first terminal; then, determining a corresponding arrangement rule number N according to the hash coding function value; finally, the arrangement rule of the red sub-channel is the arrangement rule corresponding to the arrangement rule number n+1.
Wherein, mod n can be as shown in the following table:
TABLE 1 one of the corresponding relationship tables of hash code function value and permutation rule number
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 888888888, the hash coding function value of the first terminal ID is calculated by the hash coding function, so that it can be obtained that the hash coding function value of the first terminal ID is 1, N is 0 can be determined by the corresponding relation function mod N of 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 value of each pixel in the red sub-channel is adjusted according to the arrangement rule a.
After determining the arrangement rule of the red sub-channel, the arrangement rule number of the green sub-channel may be determined according to the arrangement rule number of the red sub-channel. For example, the arrangement rule number of the green sub-channels may be g=r+1. Wherein R is the arrangement rule number of the red sub-channels.
After determining the arrangement rule of the green sub-channels, the arrangement rule number of the blue sub-channels may be determined according to the arrangement rule number of the green sub-channels. For example, the arrangement rule number of the blue sub-channel may be b=g+1.
Therefore, when the arrangement rule number of the red sub-channel is 1, the arrangement rule number of the green sub-channel is 2, and the arrangement rule number of the blue sub-channel is 3. Namely, translating the gray values of at least part of pixels in the green sub-channels according to the rule B and 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 and the ordinate of the pixels.
According to the two-dimensional code processing method, the arrangement rule of the first color sub-channels is determined according to the hash coding function and the like based on the identification information of the first terminal, and the arrangement rules of the other color sub-channels are sequentially determined, so that the determination complexity of the arrangement rules of the sub-channels of each color can be effectively improved, the risk of cracking the second two-dimensional code by a third party is reduced, and the safety of two-dimensional code processing is further improved.
In one embodiment, when 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 method comprises the steps of presetting a unified clock and a preset time window which are shared by the first terminal and the second terminal, and then enabling the first terminal and the second terminal to store a method for presetting an 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.
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 prestore the identification information of the second terminal), the first terminal and the second terminal both know the method of 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 unified clock information, the second terminal can also synchronously determine the rule of restoring the first color channel, so as to restore the first two-dimensional code.
According to the two-dimensional code processing method, 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 of the second terminal and the unified clock information, so that the second terminal can synchronously determine the rule for restoring the first color channel, and the restoring 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 safety of two-dimensional code transmission is further improved.
On the basis of the foregoing embodiment, determining, according to the identification information of the second terminal, the unified clock information, and the preset time window, the arrangement rule corresponding to the first color channel may include:
determining a current time stamp according to the unified clock information;
determining an arrangement rule of the first color sub-channels according to the identification information of the second terminal, the current time stamp and a preset time window;
determining an arrangement rule of the second color sub-channels according to the arrangement rule of the first color sub-channels;
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 sub-channel, a green color 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+nowTime/T)modN+1 (6)
wherein hashCode is a hash encoding function; the deviceID is the ID of the second terminal; the nonTime is a current timestamp determined from the unified clock information; t is a preset time window; modN is the corresponding relation function of the hash coding function value and the permutation rule number.
As can be seen from the formula (6), the current timestamp can be determined according to the unified clock information, then 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 then the value of the nonwtime/T is unchanged within 30 s.
Then, the corresponding permutation rule number N may be determined according to the hash code function value.
Finally, the arrangement rule of the red sub-channel is the arrangement rule corresponding to the arrangement rule number n+1.
Wherein, mod n can be as shown in the following table:
TABLE 2 two corresponding relationship tables of hash code function value and permutation rule number
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 the hash coding function value as 1, N can be determined as 0 by the corresponding relation function modN of 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 value of each pixel in the red sub-channel is adjusted according to the arrangement rule a.
After determining the arrangement rule of the red sub-channel, the arrangement rule number of the green sub-channel may be determined according to the arrangement rule number of the red sub-channel. For example, the arrangement rule number of the green sub-channels may be g=r+1. Wherein R is the arrangement rule number of the red sub-channels.

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, the execution body of the two-dimensional code processing method provided in the embodiment of the present application may be the second terminal. The second terminal may be an intelligent electronic device, such as a cell phone, tablet computer, notebook computer, palm computer, car mounted electronic device, wearable device, ultra-mobile personal computer (UMPC), netbook or personal digital assistant (personal digital assistant, PDA), etc. The second terminal and the first terminal may be the same type of terminal, for example, the second terminal and the first terminal may be both mobile phones. The second terminal may also be a different type of terminal than the first terminal, for example the second terminal may be a PC and the first terminal may be a mobile phone.
The application scenario of the two-dimensional code processing method provided by the embodiment of the application may be, for example, a scenario in which the first terminal and the second terminal perform remote assistance: the first terminal may be assisted by the second terminal as an assisted party. In this scenario, the first terminal may process the first two-dimensional code according to the two-dimensional code processing method provided in 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 a second two-dimensional code image sent by the first terminal and an arrangement rule corresponding to the first color channel.
The second two-dimensional code image is formed by separating color channels of the first two-dimensional code image by the first terminal, determining an arrangement rule corresponding to the first color channels of the first two-dimensional code image according to preset information, and determining according to the arrangement rule corresponding to the first color channels.
Wherein the predetermined information may include any one of the following:
identification information of the first terminal;
identification information of the second terminal, unified clock information and a preset time window; 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 embodiment described above, and will not be described herein.
After the first terminal processes the first color channels according to the arrangement rules corresponding to the color channels to determine the second two-dimensional code image, the first terminal can send the arrangement rules corresponding to the first color channels to the second terminal, and the second terminal can receive the arrangement rules corresponding to the first color channels sent by the first terminal.
For example, the second terminal may receive the arrangement rule corresponding to the first color channel while receiving the second two-dimensional code sent by the first terminal. 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 an individual 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 timing and receiving manner 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-channels in the first color channel is the arrangement rule b+c, after the second terminal receives the arrangement rule corresponding to the red sub-channels sent by the first terminal, it can be determined that the reverse arrangement rule of the corresponding red sub-channels 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 as to obtain a first two-dimensional code corresponding to the second two-dimensional code.
According to the two-dimensional code processing method, under the condition that the arrangement rule corresponding to the first color channel is determined according to the identification information of the first terminal, the arrangement rule corresponding to the first color channel is received, so that the second terminal can restore to obtain 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 may send the identification information of the second terminal to the first terminal when 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 that are common to the first terminal and the second terminal may be preset, and then the first terminal and the second terminal may be caused to store a method of preliminarily storing an arrangement rule for determining the first color channel corresponding to the identification information, the unified clock information, and the preset time window of the second terminal. Thus, 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 unified 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.
For example, when the first terminal determines that the arrangement rule of the red sub-channels 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-channels is B through the identification information, the unified clock information and the preset time window of the second terminal at the same time, thereby determining the reverse arrangement rule of the corresponding red sub-channels

Figure BDA0003225195890000152
Then, the second terminal can decode the second two-dimensional code image according to the determined reverse arrangement rule of the first color channel, so as to obtain a first two-dimensional code corresponding to the second two-dimensional code.
According to the two-dimensional code processing method, 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, and therefore the first two-dimensional code can be restored under the condition that the arrangement rule corresponding to the first color channel is not sent, and the safety of two-dimensional code transmission 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.
In summary, according to the two-dimensional code processing method provided by the embodiment of the application, by receiving the second two-dimensional code image obtained after the color channel of the first two-dimensional code image is processed by adopting the corresponding arrangement rule, the encryption transmission of the first two-dimensional code information can be realized, so that the security risk caused by the leakage of the two-dimensional code information is avoided, and the security of the two-dimensional code transmission is improved.
