Controlled Screen Sharing With Participant-Specific View Access

The patent segments the audience into different participant groups (e.g., internal team, external clients, guests) and allows the presenter to share screen content with each group selectively. This segmentation enables efficient communication with relevant parties while protecting sensitive information from unauthorized viewing, thus resolving the contradiction between communication efficiency and privacy security.

The patent applies local quality by allowing different levels of screen sharing access for different participant groups. The presenter can share specific applications, windows, or portions of the screen with certain groups while restricting access to sensitive areas for other groups. This ensures each group receives appropriate information completeness without compromising overall information security.

The patent implements preliminary action by requiring the presenter to define participant groups and screen sharing permissions before initiating the screen share. The system pre-configures the sharing rules, automatically manages distribution to appropriate groups, and handles the complexity of selective sharing in advance. This approach protects privacy while keeping the actual screen sharing operation simple for the presenter.
