The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a conference system according to an embodiment of the present disclosure. The conference system can comprise a cloud server and at least two terminal devices, and the at least two terminal devices can carry out teleconferencing through a virtual space created by the cloud server. The at least two terminal devices may be located in the same place or the same scene, or the at least two terminal devices may be located in different places or in different scenes, respectively. For example, a part of the at least two terminal devices are located in a fixed indoor scene such as in an office or at home, etc., and another part of the terminal devices are located in a mobile outdoor scene such as on a high-speed rail or in an automobile, etc., which is not limited in this application. As shown in fig. 1, taking an example that the conference system includes one cloud server 101 and three terminal devices 102, 103, and 104, the cloud server 101 is in communication connection with each terminal device, and the cloud server 101 creates a virtual space so that the three terminal devices 102, 103, and 104 perform a target conference by using the virtual space. It can be understood that the cloud server 101 may be a server cluster or a distributed server, and the terminal devices 102, 103, and 104 may include, but are not limited to, electronic devices such as a mobile phone, a tablet computer, a notebook computer, and a netbook. It is understood that the number and configuration of the devices shown in fig. 1 are for example and not intended to limit the embodiments of the present application.
The cloud server in the application is a device capable of creating a conference group and providing conference services. The cloud server in the present application may alternatively be described as "server", "cloud space", and the like.
In the conference system shown in fig. 1, a terminal device 102 and terminal devices 103 and 104 perform a conference through a virtual space created by a cloud server 101, and during the conference, each of the terminal devices 102, 103 and 104 may acquire rights such as a microphone right, a camera right, a screen sharing right and the like according to information turned on by the terminal device, collect real-time voice of a user, capture a real-time picture of a scene where the user is located, or record a shared picture on a terminal desktop and the like to generate a multimedia data stream, and upload the generated multimedia data stream to the cloud server 101 in real time, and after receiving the multimedia data stream, the cloud server 101 may process the multimedia data stream and then send the processed multimedia data stream to other terminal devices except for the terminal device that originally uploaded the multimedia data stream, so as to achieve the purpose that a plurality of terminal devices can share data such as voice, document or video in real time in the conference.
Generally, when data sharing is performed by a terminal device, data (for example, a screen and a file) to be shared may be uploaded to a cloud server, and the cloud server forwards the data to other terminal devices in a conference. However, privacy information may be carried in data uploaded by the terminal device, thereby causing privacy disclosure of the terminal device.
In view of this, the present application provides a privacy protection method and a related product, which can effectively protect the privacy security of the terminal device. The privacy protection method can be applied to a cloud server in a conference system shown in fig. 1, the conference system includes the cloud server and a plurality of terminal devices, the cloud server is connected with each terminal device in the plurality of terminal devices, and the plurality of terminal devices can perform a teleconference through a virtual space created by the cloud server. The virtual space may include a cloud desktop, the cloud server to control the cloud desktop, a second terminal device of the plurality of terminal devices to display the cloud desktop. Referring to fig. 2, fig. 2 is a schematic flowchart of a privacy protection method according to an embodiment of the present application. As shown in fig. 2, the privacy protecting method includes, but is not limited to, the following steps.
201, a cloud server receives a first shared content sent by a first terminal device.
The first terminal device is any one of a plurality of terminal devices that perform a teleconference through a virtual space created by a cloud server. Optionally, the first terminal device is a control terminal in the multiple terminal devices, that is, the first terminal device is a terminal device that obtains a cloud desktop control authority.
The first shared content may be content information uploaded to a cloud space of the cloud server by the first terminal device, such as a file (e.g., an office file, a drawing file, an audio file, a video file), a document (e.g., a PPT), a split-screen image of the first terminal device, screen recording content, and the like.
The first terminal device sends the first shared content to a cloud server for data sharing, and correspondingly, the cloud server receives the first shared content.
202, the cloud server sends first prompt information to the first terminal device when detecting that the first shared content includes the privacy information, where the first prompt information is used to prompt the first terminal device to process the privacy information.
Illustratively, the privacy information may include privacy applications and privacy content. The privacy application may include a blacklist application, which is an application that does not allow sharing, such as a financial application, a chat application, and the like. The private content may include text information or image information, such as personal information of the user, user images, programming project, and the like.
After the cloud server receives the first shared content, privacy detection may be performed on the first shared content to detect whether privacy information is included in the first shared content. The cloud server generates first prompt information under the condition that the first shared content is detected to include the privacy information, so that the first terminal device is prompted to process the privacy information, and the privacy of the first terminal device is prevented from being revealed.
In one possible implementation manner, the cloud server may detect the applications to which the first shared content relates, and determine whether the applications to which the first shared content relates include a blacklist application. In a case where the application to which the first shared content relates includes a blacklist application, it is determined that the first shared content includes private information.
In a possible implementation manner, the cloud server may detect an interface image included in the first shared content, where the interface image may be obtained by the first terminal device capturing a screen of a display interface. The cloud server may detect whether the interface image includes information of a blacklist application, where the information of the blacklist application may include an icon of the blacklist application, an operation interface of the blacklist application, and the like. The cloud server can quickly determine whether the first shared content includes a privacy application by detecting whether the interface image relates to a blacklist application.
In another possible implementation manner, the cloud server may detect text content and image content in the first shared content. For example, the cloud server may perform sensitive word detection on the text content, and in a case that the sensitive word is detected to be included in the text content, determine that the text content includes the private information. As another example, the cloud server may detect image content in the first shared content, and in a case that the image content is detected to include the user image, determine that the image content includes the privacy information.
For example, in a case that the cloud server detects that the first shared content includes private information, the private information may be tagged, so as to generate the first prompt information. The first reminder information may include the tagged privacy information.
The cloud server processes the private information to generate a shared screen 203.
And the cloud server processes the privacy information to obtain second shared content under the condition that the first shared content is detected to comprise the privacy information. The cloud server may generate a shared screen based on the second shared content, the shared screen being used to display the second shared content.
In a possible implementation manner, the cloud server may, when detecting that the first shared content includes private information, directly process the private information and generate a shared screen, so that content sharing can be achieved in time while protecting the privacy security of the first terminal device.
In another possible implementation manner, the cloud server may, after sending the first prompt message to the first terminal device when detecting that the first shared content includes the private information, interact with the first terminal device, and process the private information based on the interaction to obtain the second shared content. In this implementation manner, the cloud server processes the privacy information based on the interaction, and can more accurately determine the second shared content, and ensure that the shared screen can include the content that needs to be shared by the first terminal device, and at the same time ensure the privacy security of the first terminal device.
It is understood that, in the present application, the cloud server may perform step 202 first and then perform step 203, or may perform step 202 and step 203 at the same time.
And 204, displaying the shared screen in the cloud desktop.
Illustratively, the cloud server displays the shared screen in the cloud desktop, records a screen of the cloud desktop in real time, generates a video stream, and streams the video stream to the second terminal device, where the second terminal device is any one of the plurality of terminal devices. So that the second terminal device can display the sharing screen, thereby implementing the content sharing.
It is understood that the cloud desktop in the present application may be a cloud desktop in a virtual space, and is controlled by the cloud server. When a plurality of terminal devices perform a teleconference based on the virtual space, the cloud server can display shared content uploaded by the plurality of terminal devices in the cloud desktop, and push the content displayed on the cloud desktop to the plurality of terminal devices for display, thereby realizing content sharing. When the cloud server displays the shared screen on the cloud desktop, the shared screen can be displayed through the displays of the plurality of terminal devices without substantially displaying the shared screen through the displays.
In the embodiment of the application, the cloud server detects first shared content uploaded by the first terminal device, and when the first shared content is detected to include privacy information, the first terminal device can be prompted to process the privacy information through the first prompt information, the privacy information is processed at the same time, a shared picture is generated, the shared picture is displayed in the cloud desktop, so that the shared picture is shared to the second terminal device, sharing is achieved, and meanwhile privacy of the first terminal device can be effectively protected.
Referring to fig. 3, fig. 3 is a schematic flowchart of another privacy protection method according to an embodiment of the present application. The method is applied to a cloud server in a conference system, and as shown in fig. 3, the privacy protection method includes, but is not limited to, the following steps.
301, the cloud server receives a first shared content sent by a first terminal device.
It is understood that the specific description about the first shared content and the first terminal device may refer to the above description, and detailed description thereof is omitted here.
302, the cloud server sends first prompt information to the first terminal device when detecting that the first shared content includes the privacy information, where the first prompt information is used to prompt the first terminal device to process the privacy information.
It is understood that the specific description of the private information and the first prompting information can refer to the above related description, and will not be detailed here.
303, the cloud server determines a first area corresponding to the private information.
In the embodiment of the application, the first terminal device can acquire the interface image of the display interface of the first terminal device in real time and upload the interface image to the cloud server, so that the cloud server displays the interface image on the cloud desktop, and screen sharing is achieved. The first shared content may include an interface image uploaded by the first terminal device in real time, and the first area is an area including the privacy information in the interface image. Namely, the cloud server carries out privacy detection on the interface image, and determines a first area of the privacy information in the interface image when the interface image comprises the privacy information.
The cloud server performs a blurring process on the first area to generate a shared screen 304.
The cloud server processes the first area so that the privacy information is not displayed in the shared screen. For example, the cloud server may perform the blurring processing on the first area, or the cloud server may perform the occlusion processing on the first area.
305, the cloud server displays the shared screen in the cloud desktop.
The server does not include the privacy information in the shared picture generated after the first area is subjected to fuzzy processing, and the cloud server displays the shared picture in the cloud desktop, so that a plurality of terminal devices in the conference system can display the shared picture, and content sharing is realized.
306, the cloud server receives first indication information sent by the first terminal device, where the first indication information is used to indicate a result of processing the privacy information by the first terminal device.
After the first terminal device receives the first prompt message, the first terminal device may process the privacy message based on the first prompt message to obtain a processing result, and indicate the processing result through the first indication message. Or, the first terminal device may indicate, by the first indication information, a processing manner of the private information, so that the cloud server may process the private information based on the first indication information.
For example, in a case where the first terminal device determines to delete the private information, the first terminal device may delete the private information in the first shared content, obtain a third shared content, and send the third shared content to the cloud server. Or, the first terminal device may instruct the cloud server to delete the privacy information through the first instruction information.
307, the cloud server updates the shared picture based on the first indication information to obtain an updated shared picture.
For example, the cloud server may adjust the first area based on the first indication information, thereby updating the shared screen. It can be understood that the cloud server displays the shared image on the cloud desktop, and after the shared image is updated, the cloud server also updates the shared image displayed on the cloud desktop, that is, the cloud server displays the updated shared image on the cloud desktop. The cloud server updates the shared picture based on the first indication information, so that the shared picture can include the content to be shared by the first terminal device, and meanwhile, the privacy information of the first terminal device is not displayed, and the privacy safety of the first terminal device is guaranteed.
In one possible implementation manner, the first indication information includes third shared content, where the third shared content is shared content after the first terminal device processes the privacy information, and the updating, by the cloud server, of the shared screen based on the first indication information includes: and the cloud server updates the content of the shared screen to the third shared content. For example, after receiving the first prompt message, the first terminal device may process the privacy message to obtain the third shared content, and send the third shared content to a cloud server. After receiving the third shared content, the cloud server generates a shared screen based on the third shared content, wherein the shared screen includes the third shared content.
In another possible implementation manner, the first indication information is used for indicating a manner of processing the private information, and the updating, by the cloud server, the shared picture based on the first indication information includes: and the cloud server processes the privacy information again based on the first indication information to generate a shared picture. The cloud server may reprocess the privacy information based on the first indication information, thereby determining content that the first terminal device needs to share, and display the content that the first terminal device needs to share in the sharing screen.
For example, as shown in fig. 4A, the cloud server determines a first area corresponding to the private information, where the private information may include "ABCD", and the cloud server generates a shared screen after performing a blurring process or an occlusion process on the first area (as shown in fig. 4B). The cloud server may adjust the first area based on the first indication information after receiving the first indication information. For example, if the first indication information indicates that "ABC" in the original first area is private information and "D" is not private information, the adjusted first area only includes "ABC", that is, the cloud server only needs to perform the blurring process or the blocking process on the area corresponding to "ABC" (as shown in fig. 4C). Alternatively, the cloud server may delete the "ABC" based on the first indication information, so that the blurring or occlusion processing of the first area is not required (as shown in fig. 4D).
In the embodiment of the application, the cloud server can process the private information to generate the shared picture and display the shared picture in the cloud desktop when detecting that the first shared content includes the private information, so that the content sharing can be performed in real time while the privacy security of the first terminal device can be protected. The cloud server updates the shared picture based on the first indication information sent by the first terminal device, so that the shared picture can more accurately include the content to be shared by the first terminal device, the conference efficiency is ensured, and the privacy and the safety of the first terminal device can be effectively protected.
Referring to fig. 5, fig. 5 is a schematic flowchart of another privacy protection method according to the embodiment of the present application. The method is applied to a cloud server in a conference system, and as shown in fig. 5, the privacy protection method includes, but is not limited to, the following steps.
501, a cloud server receives first shared content sent by a first terminal device, where the first shared content includes a first shared file.
Illustratively, the first shared file may include office files, drawing files, audio files, video files, documents (such as PPT), and the like.
In the embodiment of the application, a plurality of terminal devices can carry out a conference through a virtual space created by a cloud server. The first terminal device can upload the first shared file to the cloud server, and after the cloud server receives the first shared file, the first shared file can be stored in the virtual space, so that the first shared file can be checked by a plurality of terminal devices participating in a conference, and file sharing is achieved.

For example, when the first terminal device divides the first shared content, the obtained plurality of content blocks may be identified, so that each content block corresponds to one location identifier. After receiving the location identifier, the cloud server may determine a first display area corresponding to the first content block, and display the first display area on the cloud desktop.
Optionally, the third indication information may include position information of a cursor on a display interface of the first terminal device. The first terminal equipment acquires the position of a cursor on a display interface of the first terminal equipment, so that a first content block currently explained by the user is determined.
In the embodiment of the application, the cloud server may determine the first display area to be displayed based on the third indication information sent by the first terminal device, and display the first display area in the cloud desktop, so that privacy and security of the first terminal device can be effectively protected while data sharing is achieved.
In another possible implementation manner, the one or more display areas include a second display area, and before the shared screen is displayed in the cloud desktop, the method further includes:
and receiving first voice data sent by the first terminal equipment, wherein the first voice data corresponds to the second display area.
For example, after receiving the first voice data, the cloud server may parse the first voice data, thereby obtaining the content of the first voice data. The cloud server matches the content of the first voice data with the plurality of content blocks, so that a second display area corresponding to the first voice data is determined.
In one possible implementation manner, the cloud server identifies a keyword in the first voice data, associates the keyword with a plurality of content blocks, and determines a second content block which is most matched with the first voice data, so as to determine the second display content. For example, after receiving the partition information transmitted by the first terminal device, the cloud server may determine the plurality of content blocks based on the partition information and extract keywords of the plurality of content blocks. After receiving the first voice data, the cloud server matches the keywords of the first voice data with the keywords of the plurality of content blocks, so as to determine the second content block. In this implementation, the cloud service may be able to quickly determine the second content block corresponding to the first voice data based on the keyword.
