Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic flow chart of a screen display method according to an embodiment of the invention. The method is applied to the terminal equipment, and the terminal equipment comprises the following steps: a first screen and a second screen. Here, it is preferable that the first screen and the second screen are two screens disposed oppositely. The implementation of the method is described in detail below with reference to this figure.

Step 101, when a target display event is triggered, determining that a screen matched with target biological characteristic information is a main screen and screens except the main screen are secondary screens, wherein the screen is the first screen and the second screen and is based on the biological characteristic information of the user collected by the first screen and the second screen.

In this step, the collection of the biological characteristic information can be realized by a biological identification technology (such as a fingerprint identification technology, a face identification technology, an iris identification technology, and the like).

It should be noted that the biometric information includes, but is not limited to: fingerprint information, facial feature information, iris information.

Here, the target biometric information is biometric information of the own user of the terminal device.

It should be noted that the target display event may be triggered by an input operation of the local user to the main screen, or may be triggered by an input operation of a user other than the local user to the sub screen.

Step 102, determining the screen sharing authorization state of the target display event.

It should be noted that the screen sharing authorization status includes: an authorized state and an unauthorized state.

And 103, if the screen sharing state is an authorized state, displaying a target interface corresponding to the target display event on the secondary screen.

In this step, on the premise that the screen sharing authorization status of the target display event is the authorized status, the secondary screen (i.e., the screen used by the other user except the local user) can display the target interface corresponding to the target display event, so that the privacy security of the user (the local user of the terminal device) can be ensured, and the leakage of the privacy information is prevented.

In the screen display method provided by the embodiment of the invention, under the condition that a target display event is triggered, based on the biological characteristic information of a user acquired by a first screen and a second screen, a screen which is acquired by the first screen and the second screen and is matched with the target biological characteristic information is determined to be a main screen, and screens except the main screen are sub-screens; determining a screen sharing authorization status of the target display event; and if the screen sharing state is the authorized state, displaying a target interface corresponding to the target display event on the auxiliary screen, so that the screen sharing authorized state can be determined by acquiring the biological characteristic information, thereby ensuring the privacy safety of the user and preventing the privacy information from being leaked.

Based on the embodiment shown in fig. 1, as an optional implementation manner, step 103 may further include:

and if the screen sharing authorization state is an authorized state and the current display interface of the main screen is a display interface corresponding to other display events except the target display event, displaying a target interface corresponding to the target display event on the secondary screen.

When the current display interface of the main screen conflicts with the display of the target interface corresponding to the target display event and the screen sharing authorization status of the target display event is the authorized status (it is described that the display of the target interface corresponding to the target display event does not reveal the user privacy information or the user using the secondary screen is a user trusted by the user), the target interface corresponding to the target display event is displayed on the secondary screen so as not to affect the display of the current display interface on the main screen.

In one example, the current display interface of the primary screen is a display interface of the a application, the target display event is a received message (e.g., a real-time push message, an instant messaging message, etc.), an interface including the content of the message is to be displayed, and the interface including the content of the message is displayed on the secondary screen so as not to affect the display of the current display interface on the primary screen.

In another example, the current display interface of the primary screen is a display interface of a B application, the target display event is a display interface of a C application to be displayed, and a display interface of the C application is displayed on the secondary screen so as not to affect the display of the current display interface on the primary screen.

And if the screen sharing authorization state is an authorized state and the target display event is triggered through the auxiliary screen, displaying a target interface corresponding to the target display event on the auxiliary screen.

Here, the target display event is triggered through the secondary screen, which indicates that a user (a user other than the native user) using the secondary screen wants to view a target interface corresponding to the target display event, and since the screen sharing authorization status of the target display event is an authorized status (which indicates that the display of the target interface corresponding to the target display event does not reveal user privacy information or that the user using the secondary screen is a user trusted by the native user), displaying the target interface corresponding to the target display event on the secondary screen can meet the requirements of the user using the secondary screen on the premise of ensuring the security of the user privacy.

And if the screen sharing authorization state is an authorized state and the target display event is triggered through a main screen, displaying a target interface corresponding to the target display event on the auxiliary screen and the main screen.

It should be noted that, the target display event is triggered through the main screen, which indicates that a local user using the main screen wants to view a target interface corresponding to the target display event, and in order to enable a user using the sub-screen end to share the target interface corresponding to the target display event, when the screen sharing authorization status of the target display event is authorized, the target interfaces corresponding to the target display event are displayed on both the sub-screen and the main screen, and the effect of sharing the display content on the screen can be achieved.

Based on the embodiment shown in fig. 1, as an optional implementation manner, the method may further include:

and if the screen sharing authorization state is an unauthorized state, displaying a target interface corresponding to the target display event on the main screen, and keeping the display interface on the auxiliary screen unchanged.

It should be noted that, when the screen sharing authorization status of the target display event is an unauthorized status, it is described that the content to be displayed corresponding to the target display event may relate to user privacy, and in order to ensure user privacy security, a target interface corresponding to the target display event is displayed on the main screen, and the display interface on the auxiliary screen is kept unchanged. That is, the display content corresponding to the target display event can only be viewed by the user (i.e., the local user), and cannot be shared on the secondary screen and viewed by other users.

In order to further ensure the privacy security of the user and prevent the problem that the user privacy information is leaked due to the fact that the user on the secondary screen side is a stranger who is not trusted by the local user, based on the embodiment shown in fig. 1, as an optional implementation manner, after step 101, the method may further include:

judging whether the biological characteristic information acquired based on the secondary screen is the biological characteristic information of a preset authorized user or not;

in this step, the biometric information of the user authorized to use is preset and stored in the local database of the terminal device.

It should be noted that, when the terminal device starts the screen sharing function for the first time, the biometric information of the preset authorized user authorized by the local user and allowed to share the screen (i.e., share the preset application, the preset page, or the preset message on the secondary screen) may be collected and stored in the local database of the terminal device.

And if the judgment result is negative, displaying a screen locking interface on the auxiliary screen.

Here, if the biometric information collected based on the secondary screen, that is, the biometric information of the other user except the local user, is not the biometric information of the preset authorized user, it is indicated that the user currently using the secondary screen is a strange user, and there is a risk of leakage of user privacy, so that the screen locking interface is displayed on the secondary screen, that is, no response is made to the input operation of the strange user on the secondary screen.

If yes, executing a step of determining the screen sharing authorization state of the target display event;

here, if the biometric information collected based on the secondary screen, that is, the biometric information of the other user except the local user, is the biometric information of the preset authorized user, it indicates that the current user using the secondary screen is a trusted user of the local user, and the privacy and security of the local user can be guaranteed to a certain extent.

In addition, more specifically, the screen sharing authorization states of the display events corresponding to the users with different trust degrees can be set by the local users through self-defining setting. That is, the page access rights of users with different trust degrees are also different, so as to further ensure the privacy security of the users.

Based on the embodiment shown in fig. 1, as an optional implementation manner, step 102 may include:

and if the biological characteristic information acquired based on the secondary screen is matched with the biological characteristic information in the preset authorization management information, determining the screen sharing authorization state of the target display event corresponding to the biological characteristic information acquired based on the secondary screen according to the preset authorization management information.

In this step, the presetting of the authorization management information includes: different authorized use users' biometric information shares the corresponding relationship of the authorization status with screens of different display events.

It should be noted that the correspondence between the biometric information of different authorized users and the screen sharing authorization status of different display events can be stored in the terminal device in the form of a table.

Here, the matching of the biometric information acquired by the sub-screen with the biometric information in the preset authorization management information indicates that the other users on the side of the sub-screen other than the local user are users in the authorized users of the terminal device.

It should be further noted that the biometric information acquired by the secondary screen includes at least two pieces of biometric information, and if it is determined that the screen sharing authorization statuses of the target display event corresponding to the at least two pieces of biometric information are different according to the preset authorization management information, it is determined that the screen sharing authorization status of the target display event is an unauthorized status;

here, the screen sharing authorization status of the target display event is either an authorized status or an unauthorized status, so that when the screen sharing authorization statuses of the corresponding target display events are different, an unauthorized status is inevitably present, and in order to prevent the user privacy information from being leaked and ensure the user privacy security, the screen sharing authorization status of the target display event is determined as an unauthorized status.

And if the screen sharing authorization state of the target display event corresponding to the at least two pieces of biological characteristic information is determined to be the same according to the preset authorization management information, determining that the screen sharing authorization state of the target display event is the same determined screen sharing authorization state.

Based on the embodiment shown in fig. 1, as another optional implementation manner, step 102 may include:

receiving a user authorization operation on the home screen;

in this step, specifically, an input operation of the virtual authorization switch on the main screen (i.e., a user authorization operation) may be received.

Here, if the virtual authorization switch is turned on by an input operation of the virtual authorization switch on the main screen, the screen sharing authorization status of the target display event is indicated as an authorized status.

The virtual authorization switch is closed through the input operation of the virtual authorization switch on the main screen, and the screen sharing authorization state of the target display event is an unauthorized state;

and responding to the user authorization operation, and determining the screen sharing authorization state of the target display event.

The realization mode can control the screen sharing authorization state of the target display event in real time through the user authorization operation of the main screen so as to meet the instant authorization requirement of the local user of the terminal equipment.

and if the screen sharing authorization state is an unauthorized state and an authorization confirmation operation on the main screen is received, displaying a target interface corresponding to the target display event on the auxiliary screen.

Here, when the screen sharing authorization state is an unauthorized state, if the local user of the terminal device wants to set a subsequent authorization state of the target display event, the following steps may be implemented:

receiving a user authorization indication operation on a main screen;

responding to the user authorization indication operation, and acquiring user authorization indication information;

if the user authorization indication information indicates that the target display event is allowed to be shared all the time, displaying a target interface corresponding to the target display event on the secondary screen;

if the authorization indication information indicates that the target display event is prohibited from being shared, displaying a target interface corresponding to the target display event on the main screen, and keeping the display interface on the auxiliary screen unchanged;

and if the authorization indication information indicates that the subsequent authorization state of the target display event is confirmed through real-time inquiry, displaying a target interface corresponding to the target display event on the secondary screen when an authorization confirmation operation on the main screen is received. Further, if receiving an authorized denial operation on the main screen, displaying a target interface corresponding to the target display event on the main screen, and keeping the display interface on the auxiliary screen unchanged.

It should be further noted that, if the screen authorization status of the target display event is an unauthorized status, an authorization indication setting interface as shown in fig. 2 may pop up for the native user to set the subsequent authorization status of the target display event on the home screen. Determining the level of the authorization indication through the selection operation (generally, click operation) of the user, and if the user selects 'always share', displaying a target interface corresponding to a target display event on a secondary screen; if the user selects 'forbid sharing', displaying a target interface corresponding to the target display event on the main screen, and keeping the display interface on the auxiliary screen unchanged; if the user selects 'inquiry confirmation', a window for inquiring whether to authorize or not can be popped up, and if the authorization is confirmed through the operation of the user, a target interface corresponding to the target display event is displayed on the auxiliary screen; and if the user operation is not authorized, displaying a target interface corresponding to the target display event on the main screen, and keeping the display interface on the auxiliary screen unchanged.

It should be noted that, when multiple authorized users use the secondary screen at the same time, if the levels corresponding to the authorization indications are different, the level of one authorization indication may be determined according to the priority of the preset authorization indication level.

Generally, the priority of the preset authorization indication level is, from high to low: forbidding sharing, inquiring confirmation and always sharing.

For example, if the partner a has the always sharing right, and the partner b has the inquiry confirmation right for the application, the application right is determined to be inquiry confirmation.

The following describes the implementation of the method in detail with respect to the example shown in fig. 3.

Step 301, judging whether a screen sharing function is started;

if yes, go to step 302, otherwise, end the process.

Step 302, monitoring a display event;

here, the listening for the display event may be implemented through a system message listening service.

Here, the display event may include application start or real-time message arrival.

Step 303, determining whether the display event is authorized;

if yes, go to step 304; otherwise, go to step 305;

step 304, confirming whether display content corresponding to the display event is displayed;

if yes, go to step 310, otherwise go to step 307;

step 305, displaying an authorization indication interface on a main screen;

here, a schematic diagram of the authorization indication interface may be referred to in fig. 2, and for operation of the user on the authorization indication interface and a specific screen display situation, reference may be specifically made to the explanation of the portion shown in fig. 2, which is not described herein again.

Step 306, receiving a selection operation of a sharing prohibition option on the authorization indication interface;

step 307, the secondary screen has no response;

step 308, receiving a selection operation of an all-time sharing option on the authorization indication interface;

here, after this step, return to execute step 304;

step 309, receiving a selection operation of an inquiry confirmation option on the authorization indication interface, and receiving an authorization confirmation operation of a prompt window for inquiring whether the user authorizes;

here, after this step, return to execute step 304;

in step 310, the display content is displayed on the secondary screen.

Based on the embodiment shown in fig. 1, as an optional implementation manner, before step 101, the method may further include:

and starting a screen sharing function under the condition of meeting a preset trigger condition.

Specifically, the step can be implemented in the following two ways:

in a first mode, if first biometric information matched with the pre-stored target biometric information exists in the biometric information of the user collected based on the first screen and the second screen, and other biometric information except the first biometric information is matched with the pre-stored biometric information in the biometric information of different authorized users, the screen sharing function is started.

Here, the approach is to turn on the screen sharing function based on the biometric trigger mechanism.

And in the second mode, when the virtual switch for starting the screen sharing function is turned on, the screen sharing function is started.

Here, the second mode is based on a system physical trigger mechanism, that is, by setting a virtual switch of the screen sharing function, when the virtual switch of the screen sharing function is turned on, the screen sharing function is turned on.

The following describes an implementation process of the function of opening screen sharing in detail with respect to an example shown in fig. 4.

Step 401, judging whether screen sharing is started for the first time;

if yes, go to step 402, otherwise, go to step 407 and step 408, respectively;

step 402, judging whether the biological characteristic information of the local user exists;

if yes, go to step 403, otherwise go to step 404;

step 403, extracting the biological feature information of the user of the computer;

step 404, prompting the local user to enter the biological characteristic information;

step 405, prompting the local user whether to start partner information management;

if yes, go to step 406; otherwise, go to step 407;

here, the partner information is biometric information of the authorized user. May be stored in the terminal device in the form of a table.

It should be noted that the partner information management table maintains the operation authority of each partner access application, and by default, determines whether the display content corresponding to the display event can be shared on the secondary screen by means of inquiry confirmation.

It should be noted that the user may set each buddy access scope in buddy management. For example, as shown in fig. 5, the applications that the authorized user P allows to access include: application 1, application 2, application 3, application 4, and application 5. Also, the indication of authorization of the various display events is shown in FIG. 2, including: always shared, query confirmed, and prohibited sharing.

Here, a display event, such as an application, that obtains always shared permissions may further authorize the permissions of the operable pages.

Step 406, entering partner biological characteristic information;

step 407, prompting the user whether to start a biometric trigger screen sharing mechanism;

if yes, go to step 409; otherwise, the flow ends.

Step 408, prompting a user whether to start a system physical trigger screen sharing mechanism;

if yes, go to step 410, otherwise, end the process.

It should be noted that, in the

above steps

407 and 408, the trigger screen sharing is divided into a biometric trigger and a system physical trigger, and both can be realized by setting a virtual switch, as shown in fig. 6.

Step 409, identifying whether the biological characteristic information of the local user and the biological characteristic information of the authorized user exist;

if yes, go to step 410; otherwise, the flow ends.

Step 410, the screen sharing function is started.

It should be noted that before the screen sharing function is started, the user can be prompted to confirm whether to start the screen sharing function immediately, so as to avoid the situation that the user suddenly cancels the idea of starting the screen sharing function. Specifically, the confirmation mode may be a mode of popping up a screen sharing confirmation window for the user to select as shown in fig. 7.

Based on the method, the embodiment of the invention provides the terminal equipment for realizing the method.
