Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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, but 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.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well.
The words "if", as used herein, may be interpreted as "at … …" or "at … …" or "in response to a determination" or "in response to a detection", depending on the context. Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.
In addition, the sequence of steps in each method embodiment described below is only an example and is not strictly limited.
Fig. 1 is a flowchart of a screen projection processing method according to an embodiment of the present invention, where the screen projection processing method may be executed by a source device that needs to perform screen projection. As shown in fig. 1, the method comprises the steps of:
101. and responding to screen projection operation, and if the current displayed interface is detected to contain the privacy data, encrypting the privacy data.
102. And projecting the encrypted interface to the target equipment for displaying.
For convenience of description, the screen projection processing method provided by the embodiment of the present invention is described by taking a scene in which the device a projects an interface displayed on a screen onto the device B for display as an example. In this example, the source device that needs to perform screen projection is device a, and the target device is device B.
In practical application, there may be more than one way to implement the screen projection from the device a to the device B, and the screen projection implementation way is not limited in the embodiment of the present invention. Thus, "in response to the screen-projection operation" in step 101 should be understood as: in response to device a being in a state capable of projecting a screen to device B.
During the screen projection process, the interface displayed on the screen of the device a may be a desktop of the device a or an interface included in any application installed in the device a.
Different private data may be defined according to the interface that may be displayed on the screen of the device a, so that, if it is found that the interface currently displayed on the screen of the device a contains the specified private data, the device a performs encryption processing on the private data, the purpose of the encryption processing being to make the private data in a state that is not viewable by others on the screen of the device B, where the others are users viewing the device B.
In practical application, the encryption processing of the private data may include two optional ways: firstly, performing content encryption processing on private data, namely encrypting data content contained in the private data; secondly, image encryption processing is carried out on the target area displaying the private data, namely the target area containing the private data is determined from an interface containing the private data, the target area can be intercepted in a screenshot mode, and then the image encryption processing is carried out on the target area.
Wherein, the image encryption processing can be realized as: image blurring processes such as random gaussian blurring, random motion blurring, random cropping, and the like. Alternatively, the image encryption process may be implemented as: generating an opaque layer, and displaying the layer on a target area for displaying the private data in a floating manner to block the target area, namely covering the private data with the layer, so that the private data is in an invisible state.
The content encryption of the private data can be realized as follows: certain characters are used to replace the private data, such as characters obtained by performing some encryption operation on the private data.
It was mentioned in the foregoing that different privacy data may be defined depending on the interface that may be displayed on the screen of device a, wherein the difference in interface as referred to herein may be embodied as a difference in interface type.
Based on this, when a certain interface is displayed in the screen of the device a while the device a is in a state capable of projecting a screen to the device B, the type of the interface may be recognized so as to determine the privacy data contained in the interface according to the type of the interface.
That is, when a certain interface is displayed in the screen of the device a based on the operation of the user (typically, the owner or user of the device a) corresponding to the device a, first, it is determined whether or not the interface includes the private data and where the included private data is located in conjunction with the type of the interface. Secondly, if the interface does not contain the privacy data, the interface is normally projected and displayed, namely the interface is projected to the device B for display; and if the interface contains the private data, the private data needs to be encrypted, and the encrypted interface is projected to the device B for display, so that the private data in the interface is in an invisible state in the device B.
In the embodiment of the present invention, the types of the interface are exemplarily divided into the following types: desktop, login interface, instant messaging interface. Of course, in practical applications, the method is not limited thereto. The following describes exemplary processes for encrypting private data in these interface types with reference to different embodiments.
Fig. 2 is a schematic diagram of interface changes in an encryption process of private data according to an embodiment of the present invention, and in fig. 2, it is assumed that an interface displayed on a screen of a current device a is a desktop of the device a. Assuming that the private data on the preset desktop includes icons of specific applications, such as the bank-type applications, as shown in fig. 2, it is assumed that the desktop of the device a includes an icon of the bank X, and at this time, the icon of the bank X is the private data. As shown in fig. 2, the encryption process for the private data may be: determining a target area of an icon of the bank X displayed on the desktop, generating a layer Y corresponding to the target area, and displaying the layer Y on the target area in a suspension manner so as to shield the target area. Wherein the target area may be an area surrounding the icon of bank X, which has the same size as the icon of bank X, not shown in fig. 2.
In practical application, which types of application programs on the desktop belong to the private data may be preset, so that, in the process of projecting the screen to the device B by the device a, if an interface that needs to be projected at a certain time is found to be a certain desktop, whether a preset application program icon is included in the desktop is queried, and if the preset application program icon is included, it is indicated that the encryption processing of the above example needs to be performed.
Fig. 3 is a schematic diagram illustrating an interface change of another private data encryption process according to an embodiment of the present invention, and in fig. 3, it is assumed that an interface displayed on a screen of a current device a is a login interface of an application program in the device a. Assuming that the privacy data included in the login interface is set as user login information, i.e., a user name and a login password, as shown in fig. 3, since a login interface of an application is currently displayed on the screen of the device a, the privacy data at this time is the user name and the login password illustrated in fig. 3. As shown in fig. 3, the encryption process for the private data may be: determining a target area D for displaying the private data, generating a layer Z corresponding to the target area D, and displaying the layer Z on the target area D in a suspension manner so as to shield the target area D. Alternatively, the target area D may be a minimum rectangle surrounding the user login window.
In practical application, optionally, in the process of projecting the screen to the device B, the device a may determine whether the login interface and the user login information included in the login interface are currently displayed on the screen of the device a by searching for a keyword. Specifically, the keyword may be a user name and a password, so that if the interface is found to include the two keywords, the interface is considered to be a login interface, and the position where the keyword is found is the position where the privacy data is located.
Fig. 4 is a schematic diagram illustrating an interface change of another privacy data encryption process according to an embodiment of the present invention, in fig. 4, assuming that an interface displayed on a screen of a current device a is an instant messaging interface (commonly referred to as a chat interface or a chat window) of an instant messaging application in the device a, and assuming that privacy data included in the instant messaging interface is set as an instant messaging message, as shown in fig. 4, the privacy data currently displayed on the screen of the device a is a plurality of instant messaging messages corresponding to different users illustrated in fig. 4. As shown in fig. 4, the encryption process for the private data may be: determining a target area T for displaying instant messaging messages in an instant messaging interface, generating a layer K corresponding to the target area T, and displaying the layer K on the target area T in a suspension manner.
In practical application, optionally, the instant messaging interface may be split into two regions, such as a target region T and a region M illustrated in fig. 4, where the region M is used to display each operation item included in the instant messaging interface, such as operation item 1, operation item 2, and operation item 3 illustrated in fig. 4. And taking the other areas except the area M in the instant messaging interface as target areas T. In the encryption process, only the target area T containing the instant messenger message may be encrypted, and the area M may not be encrypted.
The above fig. 2-4 only illustrate the encryption manner of the private data in the manner of generating the layer to block the private data, and in fact, as mentioned above, the encryption manner is not limited to this.
In summary, in the screen projection process, the privacy data of the screen projection person can avoid screen projection display, so that the data privacy of the screen projection person is protected.
Fig. 5 is a flowchart of another screen projection processing method provided in an embodiment of the present invention, where the screen projection processing method can be executed by the source device in the foregoing. As shown in fig. 5, the following steps may be included:
501. and responding to screen projection operation, and if the current displayed interface is detected to contain the privacy data, encrypting the privacy data.
502. And projecting the encrypted interface to the target equipment for displaying.
The above steps can be performed as described in the foregoing other embodiments, and are not described herein.
503. And displaying prompt information and a screen projection control on the encrypted interface displayed by the target equipment, wherein the prompt information is used for prompting the operation of canceling the encryption effect of the private data.
504. And if receiving the operation triggered according to the prompt information, projecting the interface which is not encrypted to the target equipment for displaying.
505. And executing the operation triggered by the user according to the screen projection control.
The implementation of steps 503 and 505 is still exemplified by the device a and the device B mentioned in the foregoing embodiments, with reference to fig. 6.
As shown in fig. 6, assuming that an instant messaging interface is currently displayed on the screen of the device a, and a plurality of instant messaging messages contained therein are used as privacy data, the encryption processing process for the privacy data is, for example, as shown in fig. 4, a layer K is displayed in a floating manner on a target area containing the privacy data to block the privacy data.
On the layer K, a prompt 601 and a screen projection control 602 may be displayed. As shown in fig. 6, in practical applications, the prompt information 601 may be composed of prompt text and an operation button, where the prompt text is used to prompt a user how to operate the operation button if the user wants to cancel the encryption effect of the private data, and the implementation form of the operation button may be a slider, a key, or even a command for triggering cancellation of the encryption effect of the private data in a voice interaction manner. In addition, in practical application, different operation buttons can be adopted according to different types of the equipment A, for example, when the equipment A is a computer, the operation buttons can be keys; when the device a is a mobile phone, the operation button may be a slider.
As shown in fig. 6, when a user (usually, a screen projector) triggers an operation on the operation button on the device a, that is, an operation for canceling the encryption effect of the private data is triggered, an instant messaging interface before encryption processing is displayed on the screen of the device a, that is, the layer K is simply removed, and at this time, a plurality of instant messaging messages serving as private data are projected onto a target device, that is, the device B, and displayed, and are in a visible state of a plurality of users.
When a user (generally, a screen projector) triggers an operation on the device a for the screen projecting control 602, a corresponding screen projecting interface may be displayed, where the screen projecting interface may include one or more operation items, such as an operation item related to screen projecting control, for example, terminating screen projecting, so that the user can implement screen projecting control.
Fig. 7 is a flowchart of another screen projection processing method according to an embodiment of the present invention, where the screen projection processing method may be executed by a target application in a source device. As shown in fig. 7, the method includes the steps of:
701. and the target application program in the source equipment receives screen projection operation triggered by the target application program.
702. And if the currently displayed interface contains the privacy data, the target application program encrypts the privacy data.
703. And the target application program projects the encrypted interface to the target equipment for display.
In this embodiment, a source device is taken as the device a in the foregoing description, and a target device is taken as the device B for illustration. The target application program runs in the device A and has screen projection related functions, and screen projection from the device A to the device B can be realized through the screen projection related functions.
In summary, the user of the device a can establish a communication connection with the device B through the screen-projection related function provided in the target application program, so that the interface displayed on the screen of the device a is transmitted to the device B through the communication connection for displaying. During the screen projection process, the target application program can encrypt the privacy data displayed in the interface of the device a. The interface may be some of the interfaces in the target application, may be interfaces in other applications, or may be a desktop of device a.
In practical applications, the target application may be an instant messaging application, but is not limited to this, for example, the target application may also be a payment application, a video conference application, and the like.
The following describes an implementation manner for implementing a screen projection function from device a to device B in conjunction with fig. 8. As shown in fig. 8, taking the target application as an instant messaging application as an example, after the user of the device a opens the instant messaging application installed in the device a, it is assumed that a home page interface 801 shown in fig. 8 is displayed on the screen of the device a, an operation item entry 802 is displayed in the home page interface 801, and when the user clicks the operation item entry 802, an operation item list 803 pops up. A plurality of operation items for the user may be included in the operation item list 803, where the plurality of operation items include operation items related to a screen projection function, such as the screen projection 804 illustrated in fig. 8.
After the user selects the operation item of screen projection 804, a screen projection interface 805 can be displayed. The user can input screen-projection setting information in the screen projection interface 805, such as an input box 806 for inputting a screen projection code illustrated in fig. 8 and a button for starting screen projection 807. Accordingly, after the user inputs the screen-projecting code displayed on the device B in the input box 806 and clicks the screen-projecting start 807, the screen-projecting connection between the device a and the device B is completed, and at this time, the device a is in a state capable of performing screen-projecting display on the device B, that is, the content displayed on the screen of the device a is displayed on the screen of the device B.
It will be appreciated that after the communication connection between device a and device B is implemented by the instant messenger application as illustrated in fig. 8, the interface within the instant messenger application does not necessarily remain displayed on the screen of device a, such as when the user of device a opens a word document or Excel form, the document or form is displayed on device a and displayed on device B by being screened.
Still taking the target application as an instant messaging application as an example, when the user of the device a realizes screen projection operation on the device B through the instant messaging application, and after communication connection between the two devices is established, the instant messaging application can detect whether the interface displayed on the screen of the device a contains privacy data, and if so, encrypt the privacy data, and screen-project the encrypted interface onto the device B for display.
As described above, the instant messaging application may detect the type of the interface currently displayed on the device a, and if it is detected that the preset type of interface is currently displayed, may further determine the location and content of the private data in the interface, so as to encrypt the private data.
As described above, for example, if the currently displayed interface on the screen of the device a is the desktop of the device a, when the instant messaging application learns that the currently displayed desktop of the device a is displayed, whether the desktop includes the icon of the preset application may be detected in a keyword search manner, and if the desktop includes the icon of the preset application, the icon of the preset application is considered as the privacy data.
For another example, if the currently displayed interface on the screen of the device a is a login interface of an application program, the instant messaging application program may search keywords such as "user name", "password" and the like from the login interface in a keyword search manner when knowing that the currently displayed login interface is displayed, and learn the content and location of the user name and the password based on the search result.
For another example, if the instant messaging application detects that a certain instant messaging interface (i.e., a chat interface) of the instant messaging application is displayed on the screen of the device a or the user is in operation of viewing the instant messaging message, the chat area in the instant messaging interface is considered to be the privacy data.
For another example, if the instant messaging application detects that the payment interface of the payment program is displayed on the screen of the device a or detects that the user views the payment message, it considers that all data or some part of the set data included in the payment interface displayed on the screen of the device a is the private data.
In practical applications, the identifier of the interface of the set type may be registered in advance in a target application program in the device a, such as an instant messaging application program, so that the instant messaging application program can know whether the current screen of the device a displays the interface of the set type based on the registration information.
In this embodiment, after the target application detects the private data, the encryption process of the private data may refer to the description in the foregoing other embodiments, which is not described herein again.
For understanding, the following screen-projection scenario is taken as an example to illustrate the encryption requirement of the instant messaging message:
suppose that a certain department of a company summarizes a conference in a year, the conference is hosted by a department supervisor, and the department supervisor displays a presentation document prepared in advance on a television screen by a terminal device of the department supervisor, wherein the terminal device of the department supervisor can be a computer or a mobile phone, and the terminal device of the department supervisor is provided with an instant messaging application program, and the screen-casting function can be realized by the instant messaging application program, as shown in fig. 8. In addition, if the department supervisor receives the instant messaging message in the conference process, when the instant messaging message is consulted, an instant messaging interface is displayed on a screen of the terminal equipment of the department supervisor, and the instant messaging interface comprises the instant messaging message and other instant messaging messages. Because the terminal equipment in charge of the department is in the screen projection state at present, all contents displayed on the screen of the terminal equipment can be projected on the television screen, and all participants can see the contents displayed on the screen of the terminal equipment in charge of the department through the television screen, so that all the participants can see the instant communication messages. The instant messaging messages belong to private data of a department supervisor and are not suitable for being seen by other people, so that the private data need to be encrypted and protected in the screen projection process to avoid being seen by other people.

903. And the first application program projects the encrypted interface to the target equipment for displaying.
In this embodiment, the first application may be a target application in the embodiment shown in fig. 7, that is, an application having a screen projection related function, and may be an instant messaging application, a payment application, or the like.
The second application is an application corresponding to the interface displayed in the device a. For example, if an instant messaging interface is currently displayed on the screen of the device a, the second application is a corresponding instant messaging application. The second application is a desktop program if the desktop of device a is currently displayed on the screen of device a.
