[0014] The following describes in more detail the embodiments of the present disclosure with reference to the drawings. Although the drawings show several embodiments of the present disclosure, it should be understood that the present disclosure may be realized in various forms and should not be construed as being limited to the embodiments described herein. On the contrary, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are used for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0015] It should be understood that the steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel, and that method embodiments may include additional steps and / or omit performing steps as shown, and the scope of the present disclosure is not limited in this respect.

[0017] It should be noted that the concepts of "first", "second", etc. mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not intended to limit the order or interdependence of functions performed by these devices, modules or units.

[0018] It should be noted that the modifications "one" and "multiple" referred to in this disclosure are general rather than limiting and should be understood as "one or more" unless the context clearly indicates otherwise, as would be understood by a person skilled in the art.

[0019] The names of messages or information exchanged between devices in the embodiments of the present disclosure are for illustrative purposes only and do not limit the scope of these messages or information.

[0020] In related technology, web page content can be shared between different users through screen sharing, and the web page content may be cloud document content or regular web page content, but this method has the following problems for the shared party: low resolution, limited by the screen resolution and network bandwidth of the sharing device and / or the shared device, and the visible range of the content on the shared device is limited by the size of the sharer's window, resulting in severe restrictions on the content and low flexibility, the rhythm of viewing the shared content is limited by the sharer's operations, preventing them from spending more time on content that they are paying more attention to, and the sharer cannot simultaneously consider the access needs of multiple shared parties for different shared content.

[0021] The related art cannot solve the above problems, and furthermore cannot meet the higher demand for document sharing. In order to solve at least some of the above problems, an embodiment of the present disclosure provides a content sharing method, which will be introduced below in conjunction with a specific embodiment.

[0022] 1 is a flowchart of a content sharing method according to some embodiments of the present disclosure. The method may be performed by a content sharing device, where the device may be implemented using software and / or hardware, and may generally be integrated into an electronic device. The method is used in a sharing terminal or a service terminal, where the service terminal may be a content sharing service terminal (e.g., a conference service terminal) to be introduced later, or a cloud document service terminal. As shown in FIG. 1, the method includes:

[0023] Step 101: In response to a screen sharing trigger operation, a screen content presenting a web page content is sent to a shared terminal, thereby causing the shared terminal to present the screen content.

[0024] Screen sharing can also be understood as screen projection, i.e., sharing content presented on a screen in the form of a video stream, allowing multiple users to view the same content synchronously. In some application scenarios, when one user initiates screen sharing, the current screen presentation content can be transmitted to other users in the form of a video stream, and the other users can present the same screen presentation content synchronously. The screen sharing trigger operation can be a specific operation that triggers screen sharing in different scenarios. For example, the scenario can be a multimedia conference scenario, and can specifically include gesture control operations (e.g., click, long press, double click, etc.), voice control operations, or facial expression control operations for screen sharing controls pre-set on a page (e.g., a multimedia conference client interface), but the embodiments of the present disclosure are not limited thereto.

[0025] The web page content may be content presented on the screen after the sharing user opens a specific web page through a current browser. In some embodiments of the present disclosure, the web page content may include a cloud document or other content. The cloud document may be a document accessible through a browser. For example, the cloud document may have a corresponding access address. The sharing user can view the cloud document by entering the access address into a browser. The cloud document can also be stored in a cloud terminal. The cloud document supports editing by users with editing privileges. The users with editing privileges may be the sharing user, the shared user, or other users with administrative privileges for the cloud document. Alternatively or additionally, if the sharing user has editing privileges for the cloud document, the sharing user can edit the cloud document in a sharing window, so that the shared user in a synchronous access state can view the edited content in the sharing window. Additionally or alternatively, if the shared user has editing privileges for the cloud document, the shared user in an asynchronous access state can edit the cloud document in a sharing window, so that the sharing user and / or other shared users can view the edited content in the sharing window. It should be noted that the specific content format of the cloud document in the embodiment of the present disclosure is not limited, and for example, the content format of the cloud document may include formats such as text, tables, schedules, audio, and video. Other content may be content that can only be accessed through a browser but cannot be edited, for example, the other content may be content of a regular web page obtained on the Internet, and the specific content format is also not limited.

[0026] The screen content may be content obtained by collecting data on a screen on which web page content is currently being presented, and may specifically include images obtained by screenshots and / or videos obtained by screen recording. A sharing user may be a user who actively initiates screen sharing, and the corresponding client is a sharing terminal. A shared user may be a user who passively performs screen sharing, for example, at least some of the participants other than the sharing user in a conference may be shared users, and the client corresponding to the shared user is a shared terminal. The content sharing method of the embodiments of the present disclosure may be performed by a sharing terminal or a service terminal, i.e., a content sharing device is installed in the sharing terminal or the service terminal.

[0027] After receiving a screen sharing trigger operation from the sharing user, the content sharing device acquires screen content in which web page content is presented on the screen of the sharing terminal and transmits the screen content to the shared terminal, thereby allowing the shared terminal and the sharing terminal to present the screen content synchronously. That is, the shared user and the sharing user can view the web page content in the screen content synchronously. When the sharing terminal performs a dynamic presentation of the web page content, the shared terminal can follow the dynamic presentation.

[0028] Step 102: obtaining identification information of the web page content, and sending the identification information to the shared terminal, so that the shared terminal asynchronously presents the web page content corresponding to the identification information based on the asynchronous access operation.

[0029] In some embodiments, the identification information may be information for uniquely characterizing web page content and used to identify one web page content among multiple web page contents. The identification information of the web page content in some embodiments of the present disclosure may be preset information, at least one of summary information of the web page content, or a web page address, etc., and may be specifically determined according to actual circumstances. The asynchronous access operation may be an operation for freely accessing the web page content displayed on the screen of the shared terminal without being restricted by the shared terminal. The access process is asynchronous with the shared terminal, is not affected by the shared terminal, and is not limited to a specific operation format. For example, the asynchronous access operation may be a trigger operation for preset asynchronous access control, a trigger operation for an asynchronous permission notification, or a slide-up or slide-down operation for the currently displayed screen content.

[0030] In some embodiments of the present disclosure, the content sharing device may obtain identification information of the web page content based on summary information of the web page content or the screen content, and then transmit the identification information to the shared terminal. After receiving the identification information of the web page content, the shared terminal may, upon detecting an asynchronous access operation by the shared user, obtain a web page address of the web page content based on the identification information of the web page content and switch the currently presented screen content to web page content presented on a new page based on the web page address. For example, the currently presented screen content may be turned off and the web page content may be presented on a new page based on the web page address. The rendering state of the web page content may be presented by starting rendering from an initial position, and the initial position may be understood as the position where the first content of the web page content is located. For example, if the web page content is a cloud document, the initial position may be the position where the first character or the first image is located in the cloud document. The rendering state of the web page state may be presented by starting rendering from a position corresponding to the asynchronous access operation, and the position corresponding to the asynchronous access operation may be the access position in the screen content of the web page content at the time the asynchronous access operation is triggered. For example, when the web page content is a cloud document and an asynchronous access operation is triggered, if the access position of the cloud document in the screen content is on line 3, the position corresponding to the asynchronous access operation is on line 3. Then, the content sharing device may switch the rendering state of the web page content in response to the shared user's free browsing operation, that is, switch the specific presentation position of the web page content.

[0031] For example, if the web page content is a cloud document and the sharing user is viewing the first line of this document, the shared terminal obtains the web page address of the cloud document, turns off the currently presented screen content, and presents this cloud document on a new page based on the web page address, and the shared user can autonomously view this cloud document, for example, view the 10th line of this cloud document, which is different from the sharing user, and the shared user can then switch to view line 10 to line 20 of this cloud document.

[0032] In some embodiments, obtaining identification information of the web page content may include obtaining summary information of the web page content based on a browser window that is a target of the screen sharing trigger operation via a system application programming interface of the sharing terminal, obtaining the identification information based on first preset information pre-added to the summary information, or extracting second preset information in the summary information as the identification information.

[0033] In some embodiments, the summary information may be related information about web page content that can be obtained through a browser window. For example, the summary information may include the title content of the current web page content and the titles of pages open in other browsers. In the following, an example will be described in which the summary information is the title content of the current web page content.

[0034] The first preset information may be information pre-added to the title content of the web page content. The first preset information may be invisible or visible characters, and the character format is not limited. The first preset information may be added before or after the sharing user presents the web page content. When the first preset information is added at different times, the specific information included therein may be different. The second preset information may be obtained by combining at least two pieces of information of the web page content, and may specifically include at least two of the title, author, and creation time.

[0035] When a tab page is in a front-end display state in a browser, the page title portion is also presented in the title of the browser window. Therefore, after presenting the web page content through the browser, the sharing terminal can read the title portion presented in the browser window that is the target of the screen sharing trigger operation through a system application programming interface (API). The content sharing device can obtain summary information of the web page content in the title portion and then extract first preset information or second preset information from the summary information. If the first preset information is extracted, it indicates that the current web page content is web page content for which the user has editing rights, such as a cloud document, and the first preset information can be determined as identification information of the web page content. Alternatively, if the second preset information is extracted, the second preset information can be directly determined as identification information of the web page content.

[0036] In some other embodiments, obtaining identification information of the web page content may include performing character recognition and address extraction on the screen content to obtain a web page address, and determining the web page address as identification information of the web page content.

[0037] In some embodiments, the web page address may be a resource address of the web page content. For example, if the web page content is a cloud document, the web page address may be an access address of the document resource of the cloud document, and the cloud document may be obtained and presented through the web page address.

[0038] When acquiring the identification information of the web page content, the content sharing device may perform character recognition on the screen content to obtain screen text. The specific character recognition method is not limited. For example, the recognition may be performed using a preset programming interface or optical character recognition (OCR). Then, the content sharing device may extract an address from the screen text based on a web page address format, determine the extracted text as the web page address, and determine the web page address as the identification information of the web page content.

[0039] In the above solution, the identification information of the web page content can be characterized using various information, and can be obtained in different ways for different information, which effectively improves the robustness of the identification information acquisition and is convenient for asynchronous access when sharing the subsequent web page.

[0040] In related technology, when web page content is a cloud document, different users can share the cloud document using an online document sharing method, but this method has the following problems: Content consistency issues: The content viewed by the sharer and the sharee may not match due to inconsistent screen or window sizes. For example, if the sharer is a computer and the sharee is a mobile phone, both devices open the document based on the cloud document's access address, and because the sharer's screen is larger, the sharee may not be able to see the content being explained by the sharer. The same is true vice versa: If the sharer is a computer and the sharee is a conference room, the conference room may see more content than the sharer. This is a performance issue with event stream tracking, which is primarily a performance issue with the cloud document itself. Because cloud documents not only support "reading" but also include many collaborative and editing capabilities, this capacity is consumed during tracking but is not required for the tracking itself.

[0041] This solution provides a shared terminal with a need for asynchronous access with the possibility of autonomously accessing shared content based on the operation of its own terminal, allowing the shared terminal to access online documents asynchronously, thereby increasing the shared terminal's freedom. Some embodiments of this solution also solve the tracking performance problem present in related technologies, and can meet higher document sharing needs.

[0042] In some embodiments of the present disclosure, a content sharing solution transmits screen content presenting web page content to a shared terminal in response to a screen sharing trigger operation, thereby causing the shared terminal to present the screen content, and also obtains identification information of the web page content and transmits the identification information to the shared terminal, thereby causing the shared terminal to asynchronously present the web page content corresponding to the identification information through an asynchronous access operation. By adopting the above technical solution, when realizing web page content sharing through screen sharing, the sharing terminal can transmit the identification information of the web page content to the shared terminal, thereby causing the shared terminal to asynchronously present the web page content through an asynchronous access operation based on the identification information, thereby solving the problem that the shared terminal may have strict restrictions and low flexibility, and enabling the shared terminal to asynchronously access the same web page content as the sharer, thereby improving the shared terminal's flexibility and content access experience, and meeting higher content sharing needs.

[0043] In some embodiments, the content sharing method may further include, after loading the web page content through a browser or switching a tab page presenting the web page content, generating first preset information of the web page content and adding the first preset information to summary information of the web page content.

[0044] If the content sharing device has editing authority over the web page content and the first preset information is added after the sharing user presents the web page content, the browser presenting the web page content may generate the first preset information in real time. The first preset information generated when different users open the web page content may be different, and the specific format of the first preset information is not limited. For example, the first preset information may be represented by zero-width characters. Alternatively, if the web page content is presented on at least two tab pages, the first preset information may include tab page information for marking the tab page on which the sharing user is currently presenting the web page content, i.e., the tab page on which the web page content is presented. Different first preset information may be generated for the same web page content presented on different tab pages.

[0045] Before step 101, the content sharing device may load and present web page content for the first time through the browser, or may again switch the tab page presenting the web page content, and may generate corresponding first preset information for the current web page content through the browser, and add the first preset information to summary information of the web page content so that the summary information can be obtained as identification information of the web page content in step 102. Switching the tab page presenting the web page content again means that the sharing terminal has already presented the tab page of the web page content but has switched to another page, and then switched from the other page back to the tab page where the web page content is located.

[0046] In the above solution, if the identification information of the web page content is the first preset information, it may be generated and added to the web page content at the time of presentation so that the web page content can be quickly identified based on the first preset information later, and specific tab page information may also be added, which helps to achieve a more preferable web page content presentation effect later.

[0047] In some embodiments, the content sharing method may further include adding the first preset information to the summary information of the web page content before the web page content is presented.

[0048] When the content sharing device has editing authority over the web page content and the timing of adding the first preset information is before the sharing user presents the web page content (for example, the web page content is a cloud document), the timing of adding the first preset information may be when the cloud document is created. The first preset information is preset information, such as visible or invisible characters, and this information is fixed information that does not change depending on the timing of opening, the opening user, the opening tab page, etc.

[0049] The content sharing device may add first preset information to summary information of the web page content before the web page content is presented, so that the first preset information can be acquired as identification information of the web page content in the above step 102. Since the content sharing device may be installed in a sharing terminal or a service terminal, the sharing terminal or the service terminal may add the first preset information to the summary information of the web page content.

[0050] In the above solution, if the identification information of the web page content is first preset information, it may be added to or pre-stored in the summary information of the web page content in advance so that the web page content can be quickly identified based on this first preset information later.

[0051] In some embodiments, when the web page content includes page entry information, the shared terminal presents new web page content in response to a trigger operation on the page entry information.

[0052] In some embodiments, the page entry information may be entry information for entering another page different from the page where the current web page content is located (e.g., a link embedded in a web page), and this page entry information may be set in the form of a control or text, and is not specifically limited. Since the number of shared terminals may be two or more, a shared terminal in an asynchronous access state may be understood as a shared terminal that asynchronously presents web page content corresponding to identification information based on the current asynchronous access operation, i.e., a shared terminal in a free browsing state.

[0053] When the web page content includes page entry information, the shared terminal is in an asynchronous access state and simultaneously receives a trigger operation on this page entry information by the shared user, obtains corresponding new web page content based on the web page address of the page entry information, and presents this new web page content on a new page, thereby enabling the shared terminal to freely browse other web page content.

[0054] In the above solution, the shared terminal can not only achieve asynchronous access to the web page content shared by the sharing terminal, but also, if the web page content further includes page entry information of other pages embedded therein, can freely browse other pages asynchronously based on this page entry information without being affected by the sharing terminal, thereby expanding the scope of asynchronous access and further improving the content access experience of the shared user.

[0055] In some embodiments, the content sharing method may further include, in response to receiving asynchronous access request information sent by the shared terminal, sending access information for the web page content of the sharing terminal to the shared terminal, so as to cause the shared terminal to determine an initial rendering state of the web page content under the asynchronous access operation based on the access information.

[0056] In some embodiments, the access information may characterize information such as the access location where the web page content presented by the sharing terminal is currently located and the currently presented access content when the asynchronous access request information is received. That is, the access information reflects the specific part of the web page content viewed by the sharing terminal before the shared terminal performs the asynchronous access operation. For example, the access information may be the 10th line of the web page content. If the sharing terminal provides an interface that supports the sharing terminal's collection and transmission of operation information on the shared web page content, the content sharing device may obtain the access information through the interface. The initial rendering state may be understood as a specific state from which the shared terminal starts rendering and presenting web page content when asynchronously presenting the web page content.

[0057] After detecting the asynchronous access operation of the shared user, the shared terminal may send asynchronous access request information to the content sharing device. After receiving this asynchronous access request information, if the web page content is a cloud document for which the content sharing device has editing rights, the content sharing device may obtain access information for the web page content of the shared terminal at that time and send this access information to the shared terminal. After receiving the access information, the shared terminal may determine the initial rendering state of the web page content under the asynchronous access operation based on the access information, obtain the web page content based on the identification information, and then render and present it in the initial rendering state, thereby realizing that when the shared terminal freely accesses the web page content, viewing can be started from the position where the shared terminal was accessing it at the time the asynchronous access operation was triggered.

[0058] For example, if the web page content is a cloud document and the sharing user is accessing the third row of the cloud document during the asynchronous access operation, the shared terminal can start free access to the cloud document from the third row of the cloud document.

[0059] In the above solution, when the shared terminal switches from screen sharing mode to free browsing mode for web page content, it can start presenting the web page content from the location that the sharing terminal is accessing at the time of switching. Thereafter, the shared terminal can autonomously present the web page content based on the operation of the shared user without being affected by subsequent changes in the shared terminal. In addition, the web page content viewed by the shared user does not jump due to switching from the screen sharing state to the asynchronous access state, ensuring the shared user's browsing continuity and improving the user's content access experience.

[0060] In some embodiments, the content sharing method may further include, in response to a page switching operation of the sharing terminal, transmitting the switched screen content of the sharing terminal to the shared terminal in an asynchronous access state, and the shared terminal switching back from the asynchronous access state to the screen sharing state and presenting the switched screen content.

[0061] In some embodiments, the page switching operation may be understood as an operation of switching the page on which the currently presented web page content is located to another page, and the web page content of the other page is presented in the screen content after the switch. Since there may be two or more shared terminals, a shared terminal in an asynchronous access state may be understood as a shared terminal that asynchronously presents web page content corresponding to identification information based on the current asynchronous access operation, i.e., a shared terminal in a free browsing state. The screen sharing state may be a state in which the screen content of the sharing terminal is presented to the shared terminal, thereby realizing synchronous presentation of the same content as the sharing terminal.

[0062] After detecting a page switching operation on a shared terminal by a sharing user, the content sharing device may acquire the switched screen content presented on the screen after switching to another page on the shared terminal, and transmit this switched screen content to the shared terminal in an asynchronous access state.After receiving the switched screen content, the shared terminal may return from the asynchronous access state to a screen sharing state, present the switched screen content, and be forcibly returned from the asynchronous access state for the web page content so as to continue to synchronously present the same screen content as the shared terminal.

[0063] In the above solution, in the process of realizing asynchronous access to the web page content shared by the sharing terminal, when the sharing terminal switches pages, the shared terminal can send the switched screen content to force the shared terminal to return to the screen sharing state, and synchronously present the switched screen content with the sharing terminal. The shared terminal can passively switch back from the asynchronous access state to the screen sharing state, ensuring that the shared terminal knows and follows when the sharing terminal switches pages, further improving the content sharing experience effect of the shared terminal.

[0064] In some embodiments, the content sharing method may further include obtaining a synchronization access request sent by the shared terminal and sending current screen content of the sharing terminal to the shared terminal, thereby causing the shared terminal to present the current screen content.

[0065] In some embodiments, the synchronous access request may be a request sent after the shared terminal in the asynchronous access state detects a trigger operation to return to the shared user's screen sharing state, and the current screen content may be content obtained by collecting data on the screen of the sharing terminal at the time the synchronous access request is received.

[0066] After the shared terminal asynchronously presents web page content corresponding to the identification information based on the asynchronous access operation, if the shared terminal is in an asynchronous access state, it may send a synchronous access request to the content sharing device after detecting a trigger operation by the shared user to return to the screen sharing state, and the content sharing device may obtain the current screen content of the sharing terminal and send this current screen content to the shared terminal, and the shared terminal may switch from the asynchronous access state to screen content sharing and return to present the current screen content.

[0067] In the above solution, in the process of realizing asynchronous access to the web page content shared by the sharing terminal, the shared terminal can spontaneously return to the screen sharing state based on the operation of the shared user and continue screen sharing with the sharing terminal, which better meets the actual needs of the user and further improves the content sharing experience.

[0068] In some embodiments, the content sharing method may further include setting asynchronous access permissions for the shared user's web page content in response to the asynchronous permission trigger operation.

[0069] In some embodiments, the asynchronous permission trigger operation may be understood as a specific operation for triggering the granting of asynchronous access permission to the web page content to the shared user, and may include a gesture control operation (e.g., click, long press, double click, etc.) on a pre-set asynchronous permission control. For example, an operation by a sharing user to grant asynchronous access to the shared user may be regarded as the asynchronous permission trigger operation. The asynchronous access permission may be understood as permission to allow the shared user to access the web page content asynchronously with the sharing user, that is, the shared user can freely access the target online document without being affected by the sharing user. The asynchronous access permission may include a viewing permission and, depending on the actual situation, may also include an editing permission and / or a sharing permission.

[0070] After detecting the asynchronous permission trigger operation, the content sharing device may send an asynchronous permission request to the web page content service terminal, and the web page content service terminal may set the shared user's asynchronous access authority to the web page content.

[0071] Specifically, when the content sharing device is installed in a sharing terminal, the content sharing device may send an asynchronous permission request to a service terminal after detecting an asynchronous permission trigger operation. Here, the service terminal may be a content sharing service terminal, and the content sharing service terminal may send the asynchronous permission request to a web page content service terminal, and the web page content service terminal may set the shared user's asynchronous access permission to the web page content. When the content sharing device is installed in a content sharing service terminal, the content sharing device may send an asynchronous permission request to a web page content service terminal after detecting an asynchronous permission trigger operation, and the web page content service terminal may set the shared user's asynchronous access permission to the web page content. When the content sharing method is used for a multimedia conference, the content sharing service terminal may be a conference service terminal.

[0072] Optionally, the content sharing method may further include at least one of: performing an asynchronous authorization trigger operation by the sharing terminal in a process of triggering screen sharing by the sharing terminal; and presenting the asynchronous access request information to the sharing terminal in response to the asynchronous access request information of the shared terminal, causing the sharing terminal to perform the asynchronous authorization trigger operation. Optionally, when the content sharing method is used in a multimedia conference, the content sharing method may further include granting asynchronous access privileges to at least some participants in the multimedia conference in response to receiving an asynchronous authorization trigger operation of a user having a predetermined identity.

[0073] The asynchronous authorization trigger operation may be realized at multiple times, such as during a sharing process, a sharing leaving process, and a multimedia conference process, and is not specifically limited.

[0074] When the content sharing device performs the asynchronous permission trigger operation, it may perform it during the process in which the sharing terminal triggers screen sharing, and / or the content sharing device may present the asynchronous access request information to the sharing terminal after receiving the asynchronous access request information of the shared terminal, and the sharing terminal may perform the asynchronous permission trigger operation based on the asynchronous access request information. This asynchronous access request information may be information that reminds the sharing user that the shared user requests asynchronous access permission, and the specific information content and format are not limited. The sharing terminal may perform the asynchronous permission trigger operation by a trigger operation or other type of operation on the asynchronous access request information.

[0075] When the content sharing method is used in a multimedia conference, after detecting an asynchronous permission trigger operation of a user with a preset identity, the content sharing device may set asynchronous access permissions for at least some of the participants to the web page content, so that at least some of the participants can asynchronously access the web page content as shared users in a subsequent screen sharing process. In this case, the asynchronous permission trigger operation targets one or more participants currently participating in the multimedia conference. The user with the preset identity may be a sharing user or any one of users who has permission permissions for the web page content.

[0076] The above solution can realize the granting of asynchronous access rights to the shared user's web page content in various scenarios, the permission format is more flexible, and the shared user can quickly switch between the screen sharing state and the asynchronous access state.

[0077] In some embodiments, the content sharing method may further include sending an asynchronous permission notification to the shared terminal, causing the shared terminal to present the asynchronous permission notification and receive an asynchronous access operation based on the asynchronous permission notification.

[0078] The asynchronous permission notification may be a notification that the shared user has already obtained asynchronous access permission for the web page, and in this case, the asynchronous access operation may be a trigger operation for this asynchronous permission notification.

[0079] After receiving the asynchronous permission notification, the shared terminal may present the asynchronous permission notification and accept the shared user's asynchronous access operation. Then, the shared terminal obtains the document access address of the target online document based on the identification information of the target online document, turns off the currently presented screen content, and switches and presents the target online document on the document page based on the document access address. The shared terminal may autonomously view the target online document.

[0080] Illustratively, FIG. 2 is a schematic diagram of screen sharing according to some embodiments of the present disclosure. As shown in FIG. 2, a real-time conference interface 200 is presented in which a sharing terminal performs screen sharing in a multimedia conference scenario, and the web page content is a cloud document. The real-time conference interface 200 may present screen content including a cloud document 201. The cloud document 201 has already been opened through a browser and is titled "Sharing Panel - Outline." The real-time conference interface 200 may further include an area 203, which may be presented superimposed on the screen content and may include an asynchronous permission control 203. The sharing user can grant a shared user asynchronous access permission for the cloud document 201 or revoke the shared user's asynchronous access permission for the cloud document 201 by triggering the asynchronous permission control 203. It should be noted that area 202 may further include various functional controls during the multimedia conference, such as microphone, camera, safety, participants, chat, share, record, facial expression, stop sharing, etc., and since the screen is already in a sharing state, the sharing control is used to re-share, which is merely an example.

[0081] Illustratively, FIG. 3 is a schematic diagram of another screen sharing according to some embodiments of the present disclosure. As shown in FIG. 3, based on FIG. 2, FIG. 3 presents a real-time conference interface 300 for the shared terminal to perform screen sharing. The real-time conference interface 300 may synchronously present the same screen content as the sharing terminal in FIG. 2, and present prompt information such as "Little A is sharing her screen". After the sharing user grants the shared user asynchronous access permission for the cloud document 201 and sends an asynchronous permission notification to the shared terminal, the real-time conference interface 300 of the shared terminal displays a non-authenticated screen. A synchronous permission notification 301 and an asynchronous access control 302 may be presented, and the asynchronous permission notification 301 may include prompt information such as "The sharer has already allowed free browsing of the document sharing panel - outline," prompting the shared user that the shared user has already obtained asynchronous access permissions for the target online document at this time; and the asynchronous access control 302 may include prompt information such as "free browsing," allowing the shared user to trigger an operation on the asynchronous access control 302 to switch from the current screen content to present a document page 400 including the cloud document 201 shown in Figure 4.

[0082] Illustratively, FIG. 4 is a schematic diagram of web page content presentation according to some embodiments of the present disclosure. As shown in FIG. 4, compared with FIG. 3, FIG. 4 switches from the screen sharing real-time conference interface 300 to a document page 400 presenting a cloud document. This document page 400 presents a cloud document 401, which is the same as the cloud document 201 in the screen content in FIGS. 2 and 3. The difference is that the cloud document 201 in FIGS. 2 and 3 is presented in the form of screen sharing, but the cloud document 401 is reloaded and presented on the page via a browser on the shared terminal. This document page 400 may further include an asynchronous access notification 402, which includes prompt information such as "free browsing has already been entered" to prompt the user that asynchronous access to the cloud document 401 is now available. In addition, this document page 400 may further be set with a synchronization access control 403, which may include prompt information such as "return to screen sharing." In response to the user's trigger operation on this synchronization access control 403, the shared terminal may return to presenting screen content from the document page 400 containing the cloud document 401, i.e., return from the document page 400 to the screen sharing real-time conference interface 300 in Figure 3.

[0083] As can be understood, the interfaces presented in the above FIGS. 2, 3, and 4 are merely schematic diagrams of content sharing scenarios in some embodiments of the present disclosure, and are merely examples and not limiting.

[0084] In some embodiments, when the web page content is a cloud document and the cloud document includes a preset anti-counterfeit mark, setting the shared user's asynchronous access permissions to the web page content includes performing setting the shared user's asynchronous access permissions to the shared user's cloud document when the check determines that the screen content includes a preset anti-counterfeit mark.

[0085] In some embodiments, the preset anti-counterfeit mark may be a mark for preventing counterfeiting of cloud documents and ensuring access security of the cloud documents. The specific expression form of the preset anti-counterfeit mark in the embodiments of the present disclosure may include various forms and is not specifically limited. For example, the preset anti-counterfeit mark may include a dark watermark, a bright watermark, a two-dimensional code, a barcode, etc.

[0086] In some embodiments of the present disclosure, a content sharing device may add a preset anti-counterfeit mark to a cloud document in advance. When the content sharing device is installed on a sharing terminal, it may obtain screen content and then send the screen content to a cloud document service terminal, and the cloud document service terminal may use a preset check program to determine whether the screen content includes the preset anti-counterfeit mark. When the content sharing device is installed on a service terminal, the service terminal includes a cloud document service terminal, and the content sharing device may use a preset check program to determine whether the screen content includes the preset anti-counterfeit mark. If the check is YES, the content sharing device may automatically set the shared user's asynchronous access permission for the cloud document, or set the shared user's asynchronous access permission for the cloud document in response to an asynchronous permission operation. If the screen content does not include the preset anti-counterfeit mark, the check is not passed, and the cloud document may be counterfeited, so setting the asynchronous access permission is not supported.

[0087] Optionally, before checking whether the screen content includes the preset anti-counterfeit mark, the content sharing device may crop the screen content to reduce the amount of image data and save time for checking. For example, if the preset anti-counterfeit mark is added to the center of the upper half of the cloud document, the content sharing device may crop the lower half of the screen content, or crop the left and right partial regions of the screen content, leaving only the middle region in the upper half that includes the preset anti-counterfeit mark.

[0088] Illustratively, FIG. 5 is a schematic diagram of a preset anti-counterfeit mark according to some embodiments of the present disclosure. As shown in FIG. 5, an exemplary cloud document 500 is presented in the figure, which may include information such as a preset anti-counterfeit mark 501, a body text, a title, and an avatar. The preset anti-counterfeit mark 501 in the figure is a bright watermark and is located in the middle area of ​​the title area of ​​the cloud document 500, which is for illustrative purposes only.

[0089] The above solution prevents the forgery of cloud documents by adding an anti-counterfeit mark to cloud documents, solves the problem of deceiving cloud document access permissions, and ensures the access security of cloud documents.

[0090] Next, a content sharing method according to some embodiments of the present disclosure will be further described with reference to a specific example. For example, FIG. 6 is a schematic diagram of web page content sharing according to some embodiments of the present disclosure. As shown in FIG. 6, a process of a sharing terminal sharing a cloud document in the form of screen sharing is presented, taking a multimedia conference scenario and a web page content as a cloud document as an example. The bold arrow in the diagram represents a specific sharing process, and the example is taken where the document represents a cloud document and the identification information of the cloud document is the first preset information. The diagram includes an interaction process between the sharing end, the conference service terminal, the cloud document service terminal, and the cloud document browser. The specific process may include: after the cloud document browser successfully loads a document or switches to a document tab page, the first preset information of the document may be generated as a unique identity identifier (ID), i.e., identification information. The unique ID is then added to the document title and sent to the cloud document service terminal. The cloud document service terminal may store a mapping relationship between the document and its unique ID. The cloud document browser can also monitor whether there is a sharing on / off event in the long-chain message of the cloud document service terminal. When the sharing terminal starts window sharing, i.e., screen sharing, it can periodically check the browser title to identify a unique ID and query the conference service terminal for a token based on this unique ID, i.e., query which document corresponds to the unique ID. The conference service terminal can obtain the query result from the cloud document service terminal and push the token information to the sharing terminal and each shared terminal.The token information includes the document's unique ID, and the conference service terminal can notify the cloud document browser to turn on sharing via the cloud document service terminal and transmit the document's unique ID, token, and share_id, where share_id represents the sharing event currently sharing the document. The cloud document browser loads the sharing code and logic and sends user operation data (including the above access information and other operation data) to the conference service terminal via the short chain, for example, the access location. The conference service terminal can push the user operation data to all participants, i.e., all shared terminals, via the long chain. When switching to the document page of the document freely viewed from the screen sharing real-time conference interface, the shared terminal can apply the access location in the user operation data and start presenting the document from the access location. After the sharing terminal ends the sharing, it can notify the cloud document browser via the conference service terminal and the cloud document service terminal, and the cloud document browser can terminate the sharing logic, recover before loading the document or switching the document tab page, and notify the cloud document service terminal to delete the unique ID of this document.
