Screen Sharing Selective Region Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screen sharing methods require the sharing of original image data, potentially leading to leakage of private information, and lack flexibility in controlling shared content.
Innovation Solution
A method and device for screen sharing that determines shareable image data by identifying confidential and nonconfidential areas within the user interface, allowing only nonconfidential data to be shared and controlling responses to user inputs based on these areas to prevent information leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If original image data is shared for screen mirroring, then complete display content is achieved, but private information leakage occurs
Solution Approach 1:
The screen is divided into multiple regions with different sharing permissions. The system identifies confidential areas (such as notification bars, running applications, and specific UI elements) and separates them from shareable areas. This segmentation allows selective sharing where only non-sensitive regions are transmitted to the receiving device, preventing private information leakage while maintaining display functionality.
Solution Approach 2:
Different regions of the screen are assigned different quality attributes regarding sharing. Confidential areas are marked with restricted sharing permissions while non-confidential areas allow normal sharing. The system dynamically adjusts the sharing behavior based on the local characteristics of each screen region, ensuring that sensitive information is protected while non-sensitive content remains accessible for collaboration.
2Adaptability or versatility
If all screen content is shared, then full functionality is available, but security risks increase
Solution Approach 1:
The screen sharing system dynamically adjusts which areas are shared based on real-time screen content analysis and user-defined preferences. As the user navigates through different applications or UI states, the system automatically updates the confidential area definitions. This dynamic adaptation allows the sharing behavior to flexibly respond to changing screen content while consistently maintaining security boundaries.
Solution Approach 2:
The system introduces an intermediary layer between the screen content and the receiving device. This intermediary processes the screen data, identifies confidential regions, and selectively blocks or masks sensitive information before transmission. The intermediary acts as a security gateway that enables flexible sharing of non-sensitive content while preventing harmful information leakage.

AI summary
This application provides a screen sharing method, a sharing device, and a receiving device. The screen sharing method includes: displaying a user interface of an application menu; establishing a connection used for screen sharing to a receiving device; determining shareable image data, where the shareable image data is a part of image data corresponding to the user interface; and sending the shareable image data to the receiving device by using the connection, so that the receiving device displays the user interface of the application menu according to the shareable image data. When this embodiment is used for screen sharing, a sharing device may send shareable image data to only a receiving device, thereby decreasing security problems caused by screen sharing.
