The following takes an electronic device as an example to exemplarily describe the privacy protection method provided by the embodiment of the present invention.

In the embodiment of the present invention, it is assumed that a user a is performing live recording or screen projection to an electronic device (hereinafter, referred to as a second electronic device) of a user B through one electronic device (hereinafter, referred to as a first electronic device). When a user a wants to share content in an application or a website with a user B, the user a usually needs to log in the application or the website through a first electronic device. For example, in one scenario, when a user a performs online education through a first electronic device, the user a may need to log in a learning website; in another scenario, when the user a plays the game commentary through the first electronic device, the user a may need to log in an application corresponding to the game. The user a may make a click input to an account information input area in a login interface of the application or website, so that the first electronic device may display a virtual keyboard or a hand-drawn input area. Then, the user a may input account information to the virtual keyboard or the hand-drawn input area displayed by the first electronic device, the first electronic device may receive and respond to the input of the user a, display a picture corresponding to the virtual keyboard or the hand-drawn input area in the process of inputting the account information by the user a, and send the picture to the second electronic device, the second electronic device may display the picture received from the first electronic device, and the picture displayed by the second electronic device does not include the input area; or the input area is a blank area; or the input area comprises information different from the information input by the user; alternatively, the input area and the information in the input area displayed by the first electronic device are displayed in different manners. By the scheme, after the electronic equipment receives the first input of the first information input into the input area of the first picture by the user, the electronic equipment does not comprise the input area in the recording picture sent to the target equipment, or the input area of the recording picture sent to the target equipment is a blank area, or the input area of the recording picture sent to the target equipment comprises second information different from the first information, or the input area of the recording picture sent to the target equipment and the input area of the first picture are different in display mode, namely the electronic equipment changes the display mode of the input area in the recording picture sent to the target equipment, so that the recording picture received by the target equipment does not comprise the input information corresponding to the first information, and other users cannot acquire the first information through the received recording picture, and further, information leakage to other user equipment can be avoided, and the safety of information input is improved.

The following describes an exemplary privacy protection method and electronic device according to an embodiment of the present invention with reference to the accompanying drawings.

As shown in fig. 2, an embodiment of the present invention provides a privacy protection method, which may be applied to an electronic device. The method may include

steps

201 and 202 described below.

Step 201, in the process of recording the screen picture, the electronic device receives a first input that a user inputs first information in an input area of a first picture.

Optionally, the input area of the first screen may include any one of: a virtual keyboard and a handwriting area.

Optionally, in a case that the input area of the first screen is a virtual keyboard, the first input may be a click input of a user on a key value in the virtual keyboard; in a case where the input area of the first screen is a handwriting area, the first input may be a drawing input of the handwriting area by the user.

In the embodiment of the invention, when a user wants to perform live screen recording or screen projection through the electronic equipment, the user can trigger the electronic equipment to start a process of recording a screen picture through inputting a certain live screen recording application program or screen projection application program so as to record the screen picture. For example, the screen may be a screen of the entire screen of the electronic device screen, or may be a screen of a certain region of the electronic device screen. The content displayed by the screen picture can be a picture acquired by a user in real time through a camera of the electronic equipment, and can also be a picture displayed by another process in the electronic equipment triggered by the user.

After the user triggers the electronic device to record the screen, if the user wants to log in a certain application program or website, the user may first trigger the electronic device to display a login interface of the application program or website, for example, the login interface may be a login interface of an application program installed in the electronic device, or may be a page modified by hypertext markup language (HTML 5) for the fifth time.

Optionally, all the interfaces corresponding to the certain application program or the website may be displayed in the currently displayed screen of the electronic device, for example, the interface may occupy all regions in the currently displayed screen, or may occupy partial regions in the currently displayed screen.

It should be noted that the certain application program or website is different from the screen recording live broadcast application program or the screen projection application program.

Optionally, the login interface may include an area for inputting account information. One scenario is that after the user triggers the electronic device to display the login interface of the application program or the website, the user can perform one click input on the account information input area, so as to trigger the electronic device to display a virtual keyboard, the virtual keyboard may include a plurality of key values, and the user can input the account information into the electronic device by inputting the key values. Another scenario is that after the user triggers the electronic device to display the login interface of the application or the website, the user may perform a click input on the account information input area, so as to trigger the electronic device to display a handwriting area, and the user may input the account information into the electronic device by drawing and inputting the handwriting area, for example, the user may draw an image, a character, or a symbol in the handwriting area.

For example, in the process of recording the screen, if the electronic device receives a click input of an icon of an application from a user, the electronic device may display a login interface as shown in fig. 3 (a), where the login interface may include an account number input area 10 and a password input area 11. When the user makes a click input to the account input area 10 or the password input area 11, as shown in (b) of fig. 3, a scenario in which the electronic device may display a virtual keyboard 12 in a screen in response to the click input. Then, the user may perform a first input on the first key value in the virtual keyboard 12, and correspondingly, the electronic device may receive the first input of the first key value of the virtual keyboard 12 in the screen. Another scenario is that, as shown in (c) of fig. 3, the electronic device may display a handwriting area 13 in the screen in response to the click input. After that, the user may input drawing information, which may be an account number or a password, in the handwriting area 13. Accordingly, the electronic device may receive drawing information input by the user and identify the drawing information input by the user to determine information that the user may want to input.

It should be noted that, in the process of recording the screen, the electronic device may continuously run the recording process. Even if the user switches the currently displayed picture to another interface, such as the login interface, the electronic device will continue to record the screen picture. The electronic device will not stop recording the screen until receiving the input of stopping recording by the user.

Optionally, the virtual keyboard may include a plurality of key values, that is, a plurality of key value regions. Each key value may be associated with at least one character, which may be, for example, a letter, a number, a symbol, or the like. In a possible implementation manner, in a case where each key value is associated with one character, if the electronic device receives an input of one key value by a user, the electronic device may determine the character associated with the key value as a character that the user wants to input. In another possible implementation manner, in the case that each key value is associated with a plurality of characters, if the electronic device receives an input of one key value by a user, the electronic device may display the plurality of characters associated with the key value in an alternative area of the virtual keyboard, and then the user may input one character of the plurality of characters, so that the electronic device determines the character as a character that the user wants to input.

Optionally, the character associated with the first key value may be a character in an account or a password used for logging in the application program or the website. For example, when the password used for logging in the application program or the website is 123, the characters associated with the first key value may be any one or more of characters "1", "2", and "3".

Optionally, the hand-drawing area may include a drawing area and a plurality of key values, the user may draw and input the drawing area, and the plurality of key values may be used for associating symbols and inputting functions. For example, the symbol may be a comma, period, question mark, exclamation mark, etc., and the input function may be a space, transmission, deletion, numeric keypad switch, etc.

Optionally, the first input may be a touch input. For example, the touch input may be a click input of the first key value in the virtual keyboard 12 by the user, or the touch input may be a drawing input of the handwriting area 13 by the user.

Step 202, the electronic device records the first picture in response to the first input to obtain a second picture, and sends the second picture to the target device.

In this embodiment of the present invention, the second screen may include one screen or a plurality of screens.

Optionally, the second screen may not include an input area; alternatively, the input area of the second screen may be a blank area; alternatively, second information different from the first information may be included in the input area of the second screen; alternatively, the input area of the second screen and the input area of the first screen may be displayed in different manners.

After the electronic device records the first screen and obtains a second screen, the electronic device may transmit the second screen to another electronic device (hereinafter, referred to as a target device). Accordingly, the target device may receive the second screen transmitted by the electronic device, and then the target device may display the second screen. The second screen seen by the user using the target device through the target device does not include an input area; or the input area of the second picture is a blank area; or the input area of the second picture comprises second information different from the first information; alternatively, the input area of the second screen and the input area of the first screen are displayed in different manners.

The second picture transmitted to the target device may be compressed with other recorded pictures and then transmitted in a packet manner, or may be a picture transmitted in real time. For example, if the pictures recorded in the recording process according to the time sequence include a picture 1, a first picture and a picture 2, the electronic device may compress and package the picture 1, the second picture and the picture 2 and send the compressed and packaged pictures to the target device after obtaining a second picture through the first picture; alternatively, the picture 1 may be transmitted first, the second picture may be transmitted after the second picture is obtained from the first picture, and the picture 2 may be transmitted last.

Since the second screen displayed by the target device may be different, step 202 will be exemplarily described below by the following 4 implementations, respectively.

Implementation mode 1: the second screen does not include an input area.

Optionally, the input area may be a virtual keyboard or a handwriting area.

Under the condition that the input area is the virtual keyboard, after the electronic equipment receives click input of a user to the account information input area in the screen picture, the electronic equipment can respond to the click input and display the virtual keyboard, namely the first picture comprises the virtual keyboard and can record the first picture, so that a third picture is obtained. Then, the electronic device may process the area where the virtual keyboard is located in the third screen, so as to obtain a second screen that does not include the virtual keyboard. After the electronic device transmits the second screen to the target devices of the other users, the target devices may display the second screen without including the virtual keyboard.

For example, as shown in fig. 4 (a), after the electronic device receives a click input of the account number input area 10 or the password input area 11 from the user on the screen, the electronic device may display a virtual keyboard 12 in response to the click input, that is, the virtual keyboard 12 is included in the first screen, and may record the first screen to obtain a third screen. Then, the electronic device may process the area where the virtual keyboard 12 is located in the third screen, so as to obtain a second screen without including the virtual keyboard 12. After the electronic device transmits the second screen to the target device of the other user, as shown in (b) of fig. 4, the target device may display the second screen not including the virtual keyboard 12.

In the case that the input area is a handwriting area, after the electronic device receives a click input of a user to an account information input area in the screen, the electronic device may display a handwriting area in response to the click input, that is, the handwriting area is included in the first screen. Under the condition that the user does not input the handwriting area, or in the process that the user hand-draws characters and the like in the handwriting area, the electronic equipment can record the first picture to obtain a third picture. Then, the electronic device may process the handwriting area in the third screen, thereby obtaining a second screen without the handwriting area. After the electronic device transmits the second screen to the target devices of the other users, the target devices may display the second screen without including the handwriting area.

For example, as shown in fig. 5 (a), after the electronic device receives a click input of the account number input area 10 or the password input area 11 from the user on the screen, the electronic device may display a handwriting area 13 in response to the click input, that is, the handwriting area 13 is included in the first screen, and may record the first screen to obtain a third screen. Then, the electronic device may change the handwriting area 13 displayed on the third screen, resulting in the second screen not including the handwriting area 13. After the electronic device transmits the second screen to the target device of the other user, as shown in (b) of fig. 5, the target device may display the second screen excluding the handwriting area 13.

Implementation mode 2: the input area of the second picture is a blank area.

In the case that the input area is a handwriting area, after the electronic device receives a click input of a user to an account information input area in the screen, the electronic device may display a handwriting area in response to the click input. After the electronic device receives a first input of a user to a handwriting area in a screen picture, the electronic device may display first information drawn by the user in response to the first input, that is, the first picture includes the first information drawn by the user, and may record the first picture to obtain a third picture. Then, the electronic device may process the first information drawn by the user in the third screen, so as to obtain a second screen with a blank handwriting area. After the electronic device transmits the second frame to the target devices of other users, the target devices can display the second frame with the handwriting area as a blank area.

For example, as shown in fig. 6 (a), after the electronic device receives a click input of the account number input area 10 or the password input area 11 from the user on the screen, the electronic device may display a handwriting area 13 in response to the click input. After the electronic device receives a first input of the user to the handwriting area 13 in the screen, the electronic device may display first information drawn by the user in response to the first input, taking the first information as the character "b", for example, that the first picture includes the character "b" drawn by the user, and may record the first picture to obtain a third picture. Then, the electronic device may process the character "b" drawn by the user in the third screen, thereby obtaining the second screen in which the handwriting area 13 is a blank area. After the electronic device transmits the second screen to the target device of the other user, as shown in fig. 6 (b), the target device may display the second screen with the handwriting area 13 as a blank area.

Implementation mode 3: the input area of the second screen includes second information different from the first information.

Optionally, the input area may be a virtual keyboard or a handwriting area.

Optionally, the electronic device may determine, through a predefined random number function, second information different from the first information from the parameter value range. When the input area is a virtual keyboard, the parameter value range may include all characters associated with key values in the virtual keyboard, or may include part of characters associated with key values in the virtual keyboard. In the case that the input area is a handwriting area, the parameter value range may include information that is different from the first information profile or has a profile similarity lower than a preset value. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

In the case that the input area is a virtual keyboard, one possible case is that all key values in the virtual keyboard are in a first display mode before the electronic device receives a first input of a first key value of the virtual keyboard in the screen. After the electronic device receives a first input of a first key value of a virtual keyboard in a screen picture by a user, the electronic device can respond to the first input, display the first key value in the virtual keyboard according to a second display mode, namely the first picture comprises the first key value displayed according to the second display mode, and record the first picture to obtain a third picture. Then, the electronic device may select a random second key value from the plurality of key values, and process an area where the first key value and the second key value are located in the third screen, so that the second key value in the virtual keyboard of the second screen is in the second display mode and other key values in the virtual keyboard of the second screen are in the first display mode. The first key value is associated with the first information, and the second key value is associated with the second information. After the electronic device sends the second screen to the target device of another user, the target device may display the second screen with the key value g in the second display mode.

For example, a first key value is taken as a key value associated with the character "b" (hereinafter referred to as a key value b), and a random second key value selected by the electronic device is taken as a key value associated with the character "g" (hereinafter referred to as a key value g). As shown in fig. 7 (a), after the electronic device receives a click input of the account number input area 10 or the password input area 11 in the screen by the user, the electronic device may display a virtual keyboard 12 in response to the click input, and after the user performs a first input on a key value b, the electronic device may display the key value b of the virtual keyboard 12 in the first screen in a second display manner. And then, the electronic equipment can record the currently displayed first picture to obtain a third picture with the key value b highlighted. Then, the electronic device may determine that the key value g is the second key value from the plurality of key values, change the key value b in the third screen to the first display mode, and change the key value g in the third screen to the second display mode, so that the key value g in the virtual keyboard 12 in the second screen is the second display mode and the other key values in the virtual keyboard 12 in the second screen are the first display mode. After the electronic device sends the second screen to the target device of another user, as shown in fig. 7 (b), the target device may display the second screen with the key value g in the second display manner.

Another possible situation is that all key values in the virtual keyboard are in the first display mode before the electronic device receives the first input of the first key value of the virtual keyboard in the screen picture by the user. After the electronic device receives a first input of a first key value of a virtual keyboard in a screen picture by a user, the electronic device can respond to the first input, select a random second key value from a plurality of key values, change a first display mode of the second key value of the virtual keyboard in the first picture into a second display mode, namely the currently displayed first picture comprises the second key value displayed according to the second display mode, and record the first picture, so that a second picture with the second key value of the virtual keyboard as the second display mode is obtained. The first key value is associated with the first information, and the second key value is associated with the second information. After the electronic device sends the second screen to the target device of another user, the target device may display the second screen with the key value g in the second display mode.

Illustratively, the first key value is taken as a key value associated with the character "b" (hereinafter referred to as a key value b), and one random second key value selected by the electronic device is taken as a key value associated with the character "g" (hereinafter referred to as a key value g). As shown in fig. 8 (a), after the electronic device receives a click input of a user to the account input area 10 or the password input area 11 in the screen, the electronic device may display a virtual keyboard 12 in response to the click input, and after the electronic device receives a first input of a key value b of the virtual keyboard 12 in the screen, the electronic device may determine the key value g as a second key value in response to the first input, and change the key value g of the virtual keyboard 12 in the first screen from a first display mode to a second display mode, that is, the currently displayed first screen includes the key value g displayed according to the second display mode, and the electronic device may record the first screen, so as to obtain a second screen in which the key value g of the virtual keyboard 12 is the second display mode. After the electronic device sends the second screen to the target device of another user, as shown in fig. 8 (b), the target device may display the second screen with the key value g in the second display manner.

In a case that the input area is a handwriting area, after the electronic device receives a first input of a user inputting first information into the handwriting area, the electronic device may display, in response to the first input, the first information drawn by the user, that is, the first information drawn by the user is included in the first picture, and may record the first picture to obtain a third picture. Then, the electronic device may randomly select one second information from an information library pre-stored in the electronic device, and change the first information drawn by the user in the third screen into the second information, thereby obtaining a second screen including the second information. After the electronic device transmits the second screen to the target devices of the other users, the target devices may display the second screen including the character "g".

For example, taking the first information as the character "b" and the second information as the character "g", as shown in fig. 9 (a), after the electronic device receives a click input of the user to the account number input area 10 or the password input area 11 in the screen, the electronic device may display a handwriting area 13 in response to the click input, and after the electronic device receives a first input of the user to input the character "b" in the handwriting area 13, the electronic device may display the character "b" drawn by the user in response to the first input, that is, the character "b" drawn by the user is included in the first screen, and may record the first screen to obtain a third screen. Then, the electronic apparatus may determine the randomly selected character "g" as the second information, and change the user-drawn character "b" in the third screen to the character "g", thereby obtaining a second screen including the character "g". After the electronic device transmits the second screen to the target device of the other user, as shown in (b) of fig. 9, the target device may display the second screen including the character "g".

Another possible scenario is that after the electronic device receives a first input of a user inputting first information into the handwriting area, the electronic device may randomly select a second information from an information base pre-stored in the electronic device in response to the first input, and change the first information in the handwriting area of the first screen into the second information, that is, the currently displayed first screen includes the second information, and the electronic device may record the first screen, so as to obtain a second screen including the second information. After the electronic device transmits the second screen to the target devices of the other users, the target devices may display the second screen including the character "g".

Illustratively, still taking the first information as the character "b" and the second information as the character "g", as shown in fig. 10 (a), after the electronic device receives a click input of the user to the account number input area 10 or the password input area 11 in the screen, the electronic device may display a handwriting area 13 in response to the click input, and after the electronic device receives a first input of the user to input the character "b" in the handwriting area 13, the electronic device may determine the character "g" as the second information in response to the first input, and change the character "b" drawn by the user in the first screen into the character "g", that is, the character "g" is included in the first screen, and the electronic device may record the first screen, so as to obtain a second screen including the character "g". After the electronic device transmits the second screen to the target device of the other user, as shown in (b) of fig. 10, the target device may display the second screen including the character "g".

Implementation mode 4: the input area of the second screen and the input area of the first screen may be displayed in different manners.

Under the condition that the input area is the virtual keyboard, all key values in the virtual keyboard are in a first display mode before the electronic equipment receives first input of a first key value of the virtual keyboard in a screen picture by a user. After the electronic device receives a first input of a first key value of a virtual keyboard in a screen picture by a user, the electronic device can respond to the first input, display the first key value in the virtual keyboard according to a second display mode, namely the first picture comprises the first key value displayed according to the second display mode, and record the first picture to obtain a third picture. Then, the electronic device may process the area where the first key value is located in the third picture, so as to obtain a second picture in which all the key values in the virtual keyboard are in the first display mode. Wherein the first key value is associated with the first information. After the electronic device sends the second picture to the target device of another user, the target device may display a second picture in which all key values in the virtual keyboard are in the first display mode.

For example, taking a first key value as a key value associated with a character "b" (hereinafter, referred to as a key value b), as shown in fig. 11 (a), after the electronic device receives a click input of a user to the account input area 10 or the password input area 11 in the screen, the electronic device may display a virtual keyboard 12 in response to the click input, and after the electronic device receives a first input of the key value b of the virtual keyboard 12 in the screen, the electronic device may display the key value b of the virtual keyboard 12 in a second display manner in response to the first input, that is, the first screen includes the key value b displayed in the second display manner, and may record the first screen to obtain a third screen. Then, the electronic device may process the region where the key value b is located in the third picture, so as to obtain a second picture in which all the key values in the virtual keyboard 12 are in the first display mode. After the electronic device sends the second screen to the target device of another user, as shown in fig. 11 (b), the target device may display the second screen in which all the key values in the virtual keyboard 12 are in the first display mode.

The embodiment of the invention provides a privacy protection method, after receiving a first input of a user for inputting first information into an input area of a first picture, an electronic device does not include the input area in a recording picture sent to a target device, or the input area of the recording picture sent to the target device is a blank area, or the input area of the recording picture sent to the target device includes second information different from the first information, or the input area of the recording picture sent to the target device and the input area of the first picture are different in display mode, that is, the electronic device changes the display mode of the input area in the recording picture sent to the target device, so that the recording picture received by the target device does not include input information corresponding to the first information, and other users cannot acquire the first information through the received recording picture, and further, information leakage to other user equipment can be avoided, and the safety of information input is improved.

Optionally, the embodiment of the present invention provides two ways for implementing privacy protection for an electronic device. One way is that the electronic device may directly display first information input by a user in a first picture, record the first picture including the first information to obtain a third picture, and then change the content displayed in the third picture to obtain a second picture; in another mode, after the electronic device receives first information input by a user, the electronic device determines second information, displays the second information in the first picture, and records the first picture to obtain a second picture. The two modes will be exemplified by the following first and second embodiments, respectively.

Example one

For example, after the step 201, before the step 202 of "recording the first picture to obtain the second picture", the privacy protecting method according to the embodiment of the present invention may further include the following step 203; the step 202 "recording the first screen to obtain the second screen and sending the second screen to the target device" may be specifically implemented by the following steps 202a, 202b, and 202 c.

Step 203, the electronic device responds to the first input and displays the first information in the input area of the first screen.

When the first input is an input of a first key value in the virtual keyboard of the first screen, the display mode of the first information corresponding to the first key value in the first screen may include the following three possible implementation modes:

in a first possible implementation, before the electronic device receives the first input, the electronic device may display each key value in the virtual keyboard in a first color. After the electronic device receives a first input of a first key value in the virtual keyboard from a user, the electronic device may display the first key value of the virtual keyboard in the first picture in a second color, and display other key values in the virtual keyboard in the first color.

In a second possible implementation manner, after the electronic device displays the virtual keyboard, if the electronic device receives a first input of the first key value by the user, the electronic device may display a scaled-up first key value in a region near the first key value in response to the first input. If the first key value is the key value of the associated letter b, after the user performs the first input on the key value of the associated letter b, the electronic device may receive and respond to the first input, and display a key value of the associated letter b enlarged in proportion in an area above the key value of the associated letter b.

In a third possible implementation manner, after the electronic device displays the virtual keyboard, the electronic device may receive a first input of the first key value by the user, and then, the electronic device may respond to the first input, and add a display special effect in an area where the first key value is located, for example, the electronic device may add a deep-trap special effect or a water ripple special effect in the area where the first key value is located, so that a visual effect that the first key value is displayed in the first screen is pressed.

In the case that the first input is an input of drawing first information in a handwriting area of the first screen, the electronic device displays the first information in an implementation manner that: after the electronic device displays the handwriting area, if the electronic device receives a first input of drawing first information by a user, the electronic device may display the first information in the handwriting area in response to the first input. If the first information is the character "b" drawn by the user, after the user performs a first input for drawing the character "b" in the handwriting area, the electronic device may receive and respond to the first input, and display the character "b" drawn by the user in the handwriting area.

It should be noted that the above four possible implementation manners are exemplary illustrations of displaying the first information on the electronic device, and it should be understood that the electronic device may have other possible implementation manners besides the four implementation manners, and the embodiment of the present invention does not limit this.

Step 202a, the electronic device records the first picture to obtain a third picture including the first information.

The electronic device provided by the embodiment of the invention can comprise a video acquisition module interface and a filter, wherein the video acquisition module interface can be used for providing video pictures acquired by the video acquisition module, and the filter can be used for processing the video pictures acquired by the electronic device from the video acquisition module interface. Specifically, after receiving the first input, the electronic device may monitor the video capture module interface, obtain video pictures captured by the video capture module from the video capture module interface, and then select, through the filter, a video picture including the user input, that is, a third picture including the first information, from the obtained video pictures.

Step 202b, the electronic device changes the display content in the third picture to obtain a second picture.

Optionally, in a case where the first input is specifically an input in which the first information is drawn in the handwriting area of the first screen, the second screen may not include the handwriting area (refer to the related description in the case where the input area is the handwriting area in implementation manner 1), or the handwriting area of the second screen may be a blank area (refer to the related description in implementation manner 2), or the handwriting area of the second screen may include the second information (refer to the related description in "one possible case is" in the case where the input area is the handwriting area in implementation manner 3).

It can be understood that, when the user draws the first information in the handwriting area of the first picture, the second picture is set to be the picture without the handwriting area or the blank area or the picture including the second information, so that the user using the target device cannot see the first information drawn by the user, and thus the user using the target device cannot acquire the first information through the second picture, thereby avoiding information leakage to the target device and improving the security of information input.

Optionally, when the first input is specifically an input of a first key value in the virtual keyboard of the first screen, the second screen does not include the virtual keyboard (refer to the related description in the case that the input area in the implementation manner 1 is the virtual keyboard), or all key values in the virtual keyboard of the second screen are in the first display manner (refer to the related description in the implementation manner 4), or the second key value in the virtual keyboard of the second screen is in the second display manner and other key values in the virtual keyboard of the second screen are in the first display manner (refer to the related description in "one possible case is" in the case that the input area in the implementation manner 3 is the virtual keyboard).

It can be understood that, when a user performs selective input on a first key value in the virtual keyboard of the first picture, the second picture is set to be a picture which does not include the virtual keyboard, or all key values in the virtual keyboard are in the first display mode, or a second key value in the virtual keyboard is in the second display mode and other key values in the virtual keyboard of the second picture are in the first display mode, so that the user using the target device cannot see first information input by the user through the virtual keyboard, the user using the target device cannot acquire the first information through the second picture, information leakage to the target device can be avoided, and the safety of information input is improved.

Alternatively, the second display mode may be a display mode different from the first display mode, for example, the first display mode may be a display mode displayed in a first color, and the second display mode may be a display mode displayed in a second color; or, the first display mode may be a display mode of a static keyboard, and the second display mode may be a display mode of displaying key values in an enlarged manner according to a proportion; or, the first display mode may be a display mode of a static keyboard, and the second display mode may be a display mode of increasing a special pressing effect. Of course, the first display mode and the second display mode may also be other possible display modes, and the embodiment of the present invention is not particularly limited.

In the case where the first input is specifically an input of a first key value in the virtual keyboard of the first screen, the step 203 may be specifically realized by the following step 203 a.

Step 203a, the electronic device changes the first key value in the virtual keyboard of the first screen from the first display mode to the second display mode.

Specifically, before the user performs the first input on the first key value, the key value in the virtual keyboard of the first screen maintains the first display mode, and after the user performs the first input on the first key value, the electronic device may change the first key value in the virtual keyboard of the first screen from the first display mode to the second display mode, so that all other key values except the first key value in the virtual keyboard of the first screen maintain the first display mode.

Optionally, a video stream processing control associated with the virtual keyboard or the handwriting area is built in the electronic device, and when the user triggers the electronic device to display the virtual keyboard or the handwriting area in a live-cast or screen-cast condition, the video stream processing control is also called accordingly. The video stream processing control can select a video stream related to the virtual keyboard or the handwriting area from the video stream collected by the video stream collecting module, namely, a third picture is obtained from the first picture; and then, the video stream processing control can change the display content in the third picture through an image processing technology, so that the second picture is obtained.

For example, the method for the video stream processing control to obtain the second picture according to the third picture may specifically include: the video stream processing control may first obtain a feature point of each video frame in the third picture. The video stream processing control may then add an index identification to each video frame based on a hashing algorithm. After the index identifier is established, the video stream processing control may perform video retrieval on the third picture, so as to obtain a video frame that needs to be deleted or blurred in the third picture, where the video frame that needs to be deleted or blurred may be a video frame that includes a virtual keyboard or a handwriting area in the third picture. After the matching is completed, the video stream processing control can delete or blur the matched video frame, and perform similarity calculation on the processed video frame and the previous and next frames of the video frame. And if the calculated similarity is larger than a preset threshold value, the video frame is considered to meet the processing requirement. The video stream processing control can then synthesize all the processed video frames into a second picture based on the previously added index identification.

Optionally, the video stream processing control may determine the feature point of each video frame through Harris corner detection, FAST, scale-invariant feature transform (SIFT), Speeded Up Robust Features (SURF), and other algorithms.

Optionally, the video stream processing control may add an index identifier to each video frame through a Local Sensitive Hashing (LSH) or a Distance Based Hashing (DBH).

Optionally, the video stream processing control may perform video retrieval through a Color Layout Descriptor (CLD), an Edge Histogram Descriptor (EHD), a Compact Fourier Mellin Transform (CFMT), and other methods.

Optionally, if the video stream processing control matches the video frame that needs to be deleted, the video stream processing control may generate a new video frame at the position of the deleted video frame through an interpolation algorithm after deleting the video frame, so as to ensure the fluency of the third picture.

Step 202c, the electronic device sends a second screen to the target device.

The specific implementation manner of the electronic device sending the second image to the target device may refer to the description about sending the second image to the target device by the electronic device in step 202, and is not described herein again.

Optionally, before step 203, the user may trigger the electronic device to turn on the asynchronous display right. Illustratively, as shown in fig. 12, a user may make an input to a control indicated by the indicator 14, and the electronic device may receive and respond to the input to turn on the asynchronous display right, thereby obtaining a second screen different from the first screen.

The privacy protection method of the embodiment of the application can be applied to a scene that the first picture and the second picture are not synchronous, and the electronic equipment can change the input area in the recorded picture under the condition that the first information is displayed, so that the second picture is obtained, on one hand, the electronic equipment can prompt a user to input errors under the condition that the user inputs wrong characters, and therefore the user can correct the errors in time; on the other hand, other users cannot know the first information input by the user through the second picture, so that the problem that the user information is leaked through the second picture can be avoided, and the safety of the user information is improved.

Example two

For example, after the step 201, before the step 202, "record the first picture to obtain the second picture", the privacy protecting method provided in the embodiment of the present invention may further include the following steps 204 and 205; the step 202 "recording the first picture to obtain the second picture, and sending the second picture to the target device" may be specifically implemented by the following steps 202d and 202 e.

Step 204, the electronic device determines second information different from the first information in response to the first input.

After receiving a first input that a user inputs first information in an input area of a first screen, the electronic device may determine, in response to the first input, second information different from the first information from a parameter value range through a predefined random number function.

For example, the input area is taken as a virtual keyboard, and the parameter value range includes a part of characters associated with key values in the virtual keyboard. If the random number function is f (x), and x has a value in the range of 26 letters, that is, x is (A, B, C … Z), the electronic device may randomly select one letter from the 26 letters according to f (x), then determine a key value associated with the letter, and determine the key value as the second key value. For example, if the letter randomly selected by the electronic device is B, the electronic device may determine a key value associated with the letter B as the second key value.

Step 205, the electronic device displays the second information in the input area of the first screen.

Optionally, when the first input is specifically an input of drawing first information in the handwriting area of the first screen, the handwriting area of the first screen and the handwriting area of the second screen both include second information (refer to the related description of "another possible case is" in the case where the input area is the handwriting area in implementation 3).

It can be understood that, when the user draws the first information in the handwriting area of the first picture, by setting the first picture and the second picture as the pictures including the second information, not only the person around the user can not obtain the first information through the first picture in the process of inputting the first information, but also the user using the target device can not obtain the first information through the second picture, thereby avoiding leakage of user information and improving the security of information input.

Optionally, when the first input is specifically an input of a first key value in the virtual keyboard of the first screen, second key values in the virtual keyboard of the first screen and the virtual keyboard of the second screen are both in the second display mode, and other key values in the virtual keyboard of the first screen and the virtual keyboard of the second screen are both in the first display mode (refer to the related description of "another possible case is" in the case that the input area is the virtual keyboard in the implementation mode 3).

It can be understood that, when a user inputs a selection of a first key value in the virtual keyboard of the first picture, by setting a second key value in the virtual keyboard of the first picture and a second key value in the virtual keyboard of the second picture as a second display mode, not only people around the user can not obtain the first information through the first picture in the process of inputting the first information, but also the user using the target device can not obtain the first information through the second picture, thereby avoiding disclosure of user information and improving the security of information input.

After the electronic device determines the second information, the electronic device may display the second information in an input area of the first screen. For a specific implementation manner of displaying the second information by the electronic device, reference may be made to the specific implementation manner of displaying the first information by the electronic device in step 203, which is not described herein again.

The second information may be different from or the same as the first information. Since the account information input by the user generally does not include only one character, even if the second information is the same as the first information, the user information is not leaked.

Step 202d, the electronic device records the first picture including the second information to obtain a second picture including the second information.

For the specific implementation manner of the electronic device recording the first picture including the second information to obtain the second picture including the second information, reference may be made to the specific implementation manner of the electronic device recording the first picture in step 202a to obtain the third picture including the first information, which is not described herein again.

Step 202e, the electronic device sends a second screen to the target device.

Optionally, before step 204, the user may trigger the electronic device to turn on the synchronous display right. Illustratively, as shown in fig. 13, the user may input the control indicated by the identifier 15, and the electronic device may receive and respond to the input to turn on the synchronous display authority, so as to obtain a second screen identical to the first screen.

The privacy protection method of the embodiment of the application can be applied to a scene that a first picture and a second picture are synchronous, and the electronic equipment can determine second information different from the first information and display the second information in the first picture and the second picture under the condition that a user inputs the first information. Therefore, on one hand, people around the user can be prevented from seeing the first information input by the user through the first picture in the process of inputting the first information, and therefore the user information is leaked; on the other hand, the user can know the display content of the second picture through the first picture, namely, the electronic equipment can avoid the problem of user information leakage through the second picture on the basis of ensuring that the display pictures on two sides are basically consistent.

Optionally, under the condition that the electronic device records the screen, if the user needs to input the account information, the user may trigger the electronic device to display a virtual keyboard or a handwriting area by inputting the area for inputting the account information. Under the condition that the virtual keyboard or the handwriting area is in the privacy protection mode, the electronic equipment can display first prompt information; in the case where the virtual keyboard or the handwriting area is in the non-privacy-preserving mode, the electronic device may display a second prompt message.

For example, before step 201, the privacy protecting method provided by the embodiment of the present invention may further include steps 206 to 208 described below.

And step 206, the electronic equipment receives a second input under the condition of recording the screen picture.

Under the condition that a user carries out screen recording live broadcast or screen projection through the electronic equipment, if the user needs to input account information, the user can carry out second input on an account number input area or a password input area in a login interface displayed by the electronic equipment. For example, the account input area and the password input area may respectively correspond to a call control, and the call control of each area may be used to generate an instruction for calling a virtual keyboard or a handwriting area, so that after the call control corresponding to the account input area or the call control corresponding to the password input area receives a second input, an instruction for calling the virtual keyboard or the handwriting area may be generated.

Optionally, the second input may be a touch input. For example, the touch input may be a user click input to an account entry area or a password entry area.

And step 207, the electronic equipment responds to the second input and displays a virtual keyboard or a handwriting area in the screen picture.

The electronic equipment provided by the invention can also comprise a user input unit, and the user input unit is used for calling the virtual keyboard or the handwriting area in the electronic equipment according to the received instruction. Specifically, after the electronic device responds to the second input and generates an instruction for invoking the virtual keyboard by invoking the control, the invoking control may send the instruction to the user input unit in the electronic device. After the user input unit receives the instruction, a virtual keyboard in the electronic device can be called, so that the electronic device displays the virtual keyboard in a screen picture. Or after the electronic device responds to the second input and generates an instruction for calling the handwriting area by calling the control, the calling control can send the instruction to the user input unit in the electronic device. After the user input unit receives the instruction, the handwriting area in the electronic device can be called, so that the electronic device displays the handwriting area in the screen picture.

Step 208, under the condition that the virtual keyboard or the handwriting area is in the privacy protection mode, the electronic equipment displays first prompt information; or, the electronic device displays the second prompt message when the virtual keyboard or the handwriting area is in the non-privacy protection mode.

It should be noted that, in the case that the virtual keyboard or the handwriting area is in the privacy protection mode, after the first prompt message is displayed, the electronic device may perform the above step 201 and step 202; in the case that the virtual keyboard or the handwriting area is in the non-privacy-preserving mode, after the second prompt message is displayed, if the user does not perform any input on the second prompt message, the electronic device may not need to perform the

above steps

201 and 202.

A virtual keyboard or handwriting area of an electronic device may include a privacy-preserving mode and a non-privacy-preserving mode. Specifically, in the case that the virtual keyboard or the handwriting area is in the privacy protection mode, the electronic device may obtain the second screen through step 202, where the second screen does not include the input area; or the input area of the second picture is a blank area; or the input area of the second picture comprises second information different from the first information; alternatively, the input area of the second screen and the input area of the first screen are displayed in different manners. Under the condition that the virtual keyboard is in the non-privacy protection mode, the second picture obtained by the electronic device is the same as the unmodified first picture, that is, if the first key value of the virtual keyboard in the first picture is the first display mode, the first key value of the virtual keyboard in the second picture is also the first display mode.

The first prompt message may be used to prompt the user that the virtual keyboard or the handwriting area is in a privacy protection mode.

For example, the first prompt message may be displayed in the form of a floating bubble, and specifically, after the electronic device displays the virtual keyboard or the handwriting area, the electronic device may display a bubble, where the bubble may include a message "please feel confident to input when the electronic device is currently in the privacy protection mode". After the user inputs the bubble, the electronic device may cancel displaying the bubble in response to the input. Of course, the display form of the first prompt message may also be other possible display forms, for example, the first prompt message may be an icon displayed in a preset area of the virtual keyboard or the handwriting area, and the icon may be used to indicate that the virtual keyboard or the handwriting area is currently in the privacy protection mode, that is, the electronic device may display a virtual keyboard or a handwriting area including the icon.

The second prompt message may be used to prompt the user that the virtual keyboard or the handwriting area is in the non-privacy protection mode, and may also be used to prompt the user to switch the virtual keyboard or the handwriting area from the non-privacy protection mode to the privacy protection mode.

For example, the second notification message may be displayed in a form of a floating frame, and the floating frame may include the notification message "whether the current mode is the non-privacy-protection mode and the mode is switched to the privacy-protection mode".

Optionally, after the electronic device calls the virtual keyboard or the handwriting area, on one hand, the electronic device may determine whether an instruction for calling the virtual keyboard or the handwriting area is generated by a control corresponding to the password input area; on the other hand, the electronic device may periodically detect whether the electronic device is currently in a live screen recording or screen projecting state, for example, the electronic device may detect the state of the electronic device in a period of ten seconds. Then, the electronic device may display the first information or the second information when it is determined that the instruction for calling the virtual keyboard or the handwriting area is generated for the control corresponding to the password input area and the electronic device is currently in a screen recording live broadcast or screen projection state.

Optionally, under the condition that the parameter name of the input area is determined to be user, password or PW, the electronic device may determine that the instruction for calling the virtual keyboard or the handwriting area is generated for the control corresponding to the password input area; or, in the case that the control generating the call instruction is determined to be a password type control, the electronic device may determine that the instruction calling the virtual keyboard or the handwriting area is generated for the control corresponding to the password input area.

Optionally, the electronic device may traverse a background service process of the electronic device, and determine that the electronic device is currently in a screen recording live broadcast state or a screen projection state when detecting that a process of screen recording software exists in the background service process; or, the electronic device may determine that the electronic device is currently in a screen recording live broadcast state or a screen projection state when detecting a target application program, where the target application program may be an application program of a video stream capture module in the monitoring electronic device.

In the embodiment of the invention, the electronic equipment can display different information under the condition that the virtual keyboard or the handwriting area is in different modes, so that a user can determine the current mode of the virtual keyboard or the handwriting area through the displayed information, and the user can determine whether to input privacy information according to the current mode of the virtual keyboard or the handwriting area.

Optionally, the information input by the user through the virtual keyboard or the handwriting area may be private information or non-private information, so that the user may trigger the electronic device to control the virtual keyboard or the handwriting area to be in different modes, so that the user may input private information when the virtual keyboard or the handwriting area is in the privacy protection mode, and input non-private information when the virtual keyboard or the handwriting area is in the non-privacy protection mode.

Illustratively, after step 208, the privacy protecting method provided by the embodiment of the present invention may further include step 209 and step 210 described below.
