Selective Application Window Sharing for Mobile Information Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen sharing technologies on mobile terminals share all contents displayed on the screen by default, compromising information security by inadvertently leaking personal information from non-intended applications during screen sharing.
Innovation Solution
A content sharing control method that allows users to select and lock specific applications for sharing through a multitask management page, using a content sharing control widget to determine and share only the desired application's content, while preventing other applications' content from being shared.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all contents displayed on the screen are shared by default, then screen sharing functionality is simple and easy to operate, but information security deteriorates due to inadvertent leakage of personal information from non-intended applications
Solution Approach 1:
The patent segments the screen sharing function by application window. Instead of sharing all screen contents uniformly, the system divides the display into separate shareable units corresponding to different application windows. Users can select specific application windows to share, thereby preventing unintended information leakage from non-selected applications while maintaining ease of use through intuitive selection interfaces.
2Object-affected harmful factors
If selective content sharing by application window is implemented, then information security is improved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The patent implements a universal sharing control mechanism that works across all application windows through a unified interface. The same control mechanism (e.g., sharing button or selection interface) can be applied to any application window, providing consistent behavior throughout the system. This multi-functional approach simplifies the control mechanism design while enabling selective sharing, as the same mechanism handles both single-application and multi-application sharing scenarios.
3Object-affected harmful factors
If only specific application content is shared, then information security and user control are improved, but ease of operation deteriorates due to additional selection steps
Solution Approach 1:
The patent applies preliminary action by pre-displaying a list of available application windows or content items before the sharing operation. The system prepares and presents selection options in advance (e.g., through a dropdown menu, grid view, or multi-select interface), allowing users to quickly identify and select desired content without navigating through multiple layers of interfaces. This pre-preparation reduces the operational steps required during actual sharing.

AI summary
A content sharing control method includes: displaying a multitask management page, wherein the multitask management page comprises at least one application window corresponding to at least one application; when a selection operation is performed on any one application window of the at least one application window corresponding to the at least one application, obtaining a first display content of a first application corresponding to a selected first application window; and sharing the first display content to a share-receiving terminal.
