The disclosure relates to application management techniques based on multi-screen sharing, and more particularly to an application management method and device based on multi-screen sharing, and a storage medium.
Along with rapid development of wireless communication techniques, wireless-communication-based wireless display, such as a Wireless Fidelity-Display (WiFi-Display) technology, finds a more and more widespread utilization. A user may conveniently project content on a screen of a mobile phone or tablet equipment onto large-screen display equipment through such a wireless display connection, which is usually applied to aspects of multi-party conference, audio and video entertainment, games and the like. A wireless-display-based screen projection function refers to projecting content of a screen of the whole smart terminal (a Source) onto display equipment (a Sink). However, under many circumstances, a user usually desires to display only a part of content, particularly contents of some specific applications. Moreover, on the premise that Sink equipment supports an input control function, an application-level multi-screen sharing function may be provided, for example, a friend of the user may access and operate, on another piece of smart terminal equipment, an application of a local Source through a wireless display connection.
During multi-screen sharing, a user may usually consider privacy and security management problems, some applications may not be suitable to be shared, and some applications may be shared only after being subjected to some limitations on functions and rights. Therefore, it is necessary to correspondingly perform dynamic management so as to implement differentiated processing of different levels on different applications in a sharing mode and a normal mode.
Unfortunately, at present, there is yet no related technical solution for display security management based on multi-screen sharing.
In order to solve the aforementioned technical problem, embodiments of the disclosure provide an application management method and device based on multi-screen sharing and a storage medium, which may set a corresponding security attribute according to a privacy requirement of an application so as to implement hierarchical display sharing of the application.

In the embodiments of the disclosure, security attributes of local applications are divided into different levels at first, including types of full function sharing, local sharing and unshareable; and for applications of which security attributes are local sharing, different active states are adopted for distinguishing a normal mode and an application sharing mode respectively, to provide a further rights management distinguishing mechanism. According to the embodiments of the disclosure, local user's normal use of the application is not affected, furthermore, when the application is shared to a remote user, it is also possible to meet requirements in terms of rights management of application functions on a local terminal and personal privacy management.
In order to make the purpose, technical solutions and advantages of the disclosure clearer, the embodiments of the disclosure will be described below in detail with reference to the drawings. It is important to note that the embodiments in the disclosure and characteristics in the embodiments may be freely combined under the condition of no conflicts.
In step 101: when it is detected that an application is started, it is determined whether the application is an application to be shared.
Before Step 101 is executed, the application to be shared is registered. That is, local applications are divided into applications to be shared and applications not to be shared. The applications not to be shared are started and closed like normal applications, and these applications may not be displayed and shared to remote users. For the applications registered to be shared, these applications may be displayed and shared to the remote users.
In the step, when it is detected that the application is started, it is determined whether the application is the application registered to be shared, and if YES, the application is the application to be shared, otherwise the application is an application not to be shared.
It is required to set a security attribute for the application to be shared, and an attribute value of the security attribute at least includes full function sharing, local sharing and unshareable.
It is important to note that setting the security attribute of the application and performing registration for sharing on the application may be performed before a wireless connection is formed between local and remote users or after the wireless connection is formed.
In step 102: when it is determined that the application is the application to be shared, a security attribute of the application is acquired, and sharing of the application corresponding to an attribute value of the security attribute is provided to a remote user according to the attribute value.
In the step, providing sharing of the application corresponding to the attribute value of the security attribute to the remote user according to the attribute value specifically includes cases as follows.
When the attribute value of the security attribute of the application is full function sharing, the application is executed, and an execution result of the application is provided to the remote user in real time.
Herein, when the value of the security attribute of the application is full function sharing, the application does not involve any personal privacy of the user and may completely be shared and displayed to the remote user, and the remote user may also control the application without function limits.
When the attribute value of the security attribute of the application is local sharing, it is determined whether it is currently in a sharing mode, if YES, a state of the security attribute of the application is set to be active, the application is executed, and the execution result of the application is limitedly provided to the remote user in real time, and when it is currently in non-sharing mode, the state of the security attribute of the application is set to be inactive, and the execution result of the application is not provided to the remote user.
Herein, when the attribute value of the security attribute of the application is local sharing, the application may be shared to the remote user in the sharing mode, its security attribute may be set into the active state, and some functions or rights may further be limited according to the active state to avoid any private information of the local user being involved at the same time when the remote user shares the application; while in the non-sharing mode, the application may run normally and the local user is not limited to use the application, which brings convenience to normal use of the local user, and in the non-sharing mode, running data of the application may also not be shared to the remote user.
When the attribute value of the security attribute of the application is unshareable, the application is executed, and the execution result of the application is not provided to the remote user.
Herein, when the attribute value of the security attribute of the application is unshareable, it is equivalent to that the application is an application not registered to be shared and is equivalent to a local ordinary application not to be shared.
The essence of the technical solutions of the embodiments of the disclosure will be further elaborated below with a specific example.
In the example, descriptions are made by taking local user equipment and remote display, which establish a WiFi-Display connection, as an example.
The local user equipment (as the Source) establishes a wireless display connection with display equipment (as the Sink), and then the Source sets applications which may be shared and initializes security attributes of different levels. Then, an application, such as an application A, is selected from the applications which may be shared, and registered as an application to be shared, and then the application A is started. Before the application A is started, a system may automatically determine the application to be started, and if the application to be started is an application to be shared, the system updates a security attribute of the application (corresponding to a sharing mode), otherwise executes normal starting.
If a user normally starts a certain application, the application may not be registered as an application to be shared, so that its security attribute may not be updated.
In another usage scenario, when the application A is stopped to be shared, the Source may also continue sharing another application, such as an application B, and at this moment, the security attribute of the application B may be correspondingly updated, while the application A may be closed and its security attribute is recovered (corresponding to a normal mode).
After some changes are made in the abovementioned usage scenarios, a basic rule is still applicable. For example, the Source initiates a wireless display connection again during application starting, and further determines whether it is necessary to update the security attribute.
Herein, after security attributes of shared applications are updated (activated), during practical running, their function use or calling rights or accessible equipment resources may correspondingly change, and a specific implementation mode may not be limited here. For example, part of function entries may be determined by virtue of the abovementioned attributes in some system applications, and the applications with the attributes may also be locally limited in terms of right access by right management control. In addition, when a remote Sink user uses a shared application, the user of the Source may simultaneously operate the local terminal equipment, but may not run the same application because each application corresponds to only one security attribute at the same time, so that resource conflicts are avoided.
In step 201: a Source is started, a system enters a standby state after being initialized, and the Source and a Sink establish a WiFi-Display connection after mutual scanning.
In step 202: the Source initializes security attributes of applications, including “full function sharing”, “local sharing” and “unshareable”, herein the applications with the “local sharing” attribute are required to be dynamically updated according to whether it is in a sharing mode, and the attribute has two states: active and inactive, and is set to be the “inactive” state during initialization.
In step 203: the Source selects an application to be shared from a list of applications with attributes “full function sharing” and “local sharing”, registers the current application as the application to be shared in the system, and then starts the application, herein this operation may usually be completed by a sharing management sub-module, including management over the WiFi-Display connection.
In step 204: when an application is started, an application management sub-module is required to determine whether there is a match between the application to be started and the application to be shared, i.e., whether they are a same application.
In step 205: if the application to be started is the application to be shared, a security attribute is determined, and the state is correspondingly updated in case of local right.
In step 206: after the abovementioned pre-processing is completed, the application is normally started.
In step 207: after a period of time, the user completes sharing, and is going to close the application on the Source.
In step 208: before the closing operation, if determining the security attribute of the application is “local sharing” and is in the “active” state, the application management sub-module updates it into the “inactive” state.
In step 209: closing processing of the application is completed.
In step 301: initialization work during starting is executed, including that an application management sub-module acquires an application name, security attribute, starting parameter and the like of an application to be started.
In step 302: the application management sub-module acquires a name of a registered application to be shared from a system.
In step 303: it is determined whether the registered application to be shared is the same as the application to be started, and if NO, Step 306 is executed for normal starting.
In step 304: if they are the same application, whether its security attribute is “local sharing” is determined, and if NO, Step 306 is executed for normal starting (other attributes do not involve state modification).
In step 305: if the security attribute of the current application is “local sharing”, a state of the attribute is set to be an “active” state to limit functions, rights or resource access to a certain extent.
In step 306: the application is normally started.
