Touch Screen Application Privacy Protection via Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face complexity in protecting personal application data during screen sharing between electronic devices, as existing methods require manual intervention to prevent sharing of sensitive information, such as messages or address books, when switching between shared screens.
Innovation Solution
An electronic apparatus method that senses touch tracks on a touch screen to add or remove application programs from a prohibited list, stopping screen sharing when a prohibited application is opened, allowing users to easily protect specific applications from being shared through intuitive gesture operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual intervention is used to stop screen sharing when switching to protected applications, then application privacy is protected, but operation complexity increases
Solution Approach 1:
The system performs preliminary action by automatically detecting when a protected application is launched during screen sharing and proactively stopping the screen sharing function before privacy leakage can occur. This eliminates the need for users to manually intervene to stop sharing, as the system has already taken preventive action by detecting the protected application and automatically halting the sharing process.
Solution Approach 2:
The system implements self-service by autonomously monitoring running applications, detecting when protected applications are launched, and automatically stopping screen sharing without requiring user intervention. The system serves itself by managing its own screen sharing state based on application detection, freeing users from manual operation complexity.
2Reliability
If screen sharing is stopped manually to protect application content, then privacy information is secured, but sharing continuity is interrupted
Solution Approach 1:
The system applies dynamics by making screen sharing state adjustable and responsive rather than static. Screen sharing automatically transitions between active and stopped states based on the detected application type. When protected applications are detected, sharing dynamically stops; when non-protected applications are used, sharing continues, creating a flexible system that adapts to different usage scenarios.
Solution Approach 2:
The system takes preliminary action by pre-configuring a whitelist of protected applications and automatically comparing running applications against this list. This preliminary setup enables the system to proactively stop screen sharing before privacy leakage occurs, rather than waiting for manual user intervention after the fact.
3Reliability
If all applications are protected from screen sharing, then maximum privacy protection is achieved, but usability of screen sharing function is reduced
Solution Approach 1:
The system applies local quality by implementing differential privacy protection across different applications rather than applying a uniform protection policy to all applications. Protected applications in the whitelist receive automatic screen sharing interruption, while non-protected applications allow continuous sharing. This localized approach to privacy protection maintains screen sharing usability for legitimate purposes while protecting sensitive applications.
Solution Approach 2:
The system uses dynamics by making the screen sharing state flexible and application-dependent rather than fixed. The system dynamically adjusts sharing behavior based on the currently running application, automatically enabling or disabling sharing based on whether the application is in the protected whitelist, thereby balancing privacy protection with usability.

AI summary
Disclosed is a method for protecting application programs of an electronic apparatus. The electronic apparatus is provided with a touch screen, and stores a screen sharing program, other application programs, a prohibited list, a first touch track and a second touch track. The electronic apparatus runs the screen sharing program to share the screen, and senses a touch track of a user on the touch screen, when the first touch track is sensed, adds an application program corresponding to it into the list; when the second touch track is sensed, deletes an application program corresponding to it from the list; and when a point touch is sensed, searches for whether an application program corresponding to it is in the list, if yes, the screen sharing program stops screen sharing and then runs the application program; otherwise, the application program is run, and the screen sharing program performs normal screen sharing.
