Screen Sharing Content Exclusion Using Element Capture Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During screensharing sessions, sensitive information such as financial or personal data may unintentionally be shared, posing a risk to privacy.
Innovation Solution
Assigning capture values to elements within content to determine whether they should be shared, allowing elements with a 'shareable' value to be sent and excluding those with a 'not shareable' value from the screensharing session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all content is shared during screensharing session, then sharing completeness is improved, but information security deteriorates
Solution Approach 1:
The patent segments the screen content into multiple independent elements (e.g., image elements, video elements, audio elements) and applies different capture values to each element. This allows the system to share some elements while excluding others, resolving the contradiction between sharing completeness and information security by enabling selective sharing at the element level rather than all-or-nothing sharing.
Solution Approach 2:
The patent assigns different capture values (shareable or not shareable) to different elements based on their specific characteristics and sensitivity. This local differentiation allows each element to have its own sharing policy, enabling the system to maximize sharing of safe content while protecting sensitive content, thus resolving the contradiction between comprehensive sharing and security.
2Object-affected harmful factors
If capture value determination is implemented at element level, then information security is improved, but system complexity increases
Solution Approach 1:
The content provider determines capture values for elements in advance before the screensharing session begins. This preliminary assignment of capture values simplifies the system operation during the actual screensharing, as the computing device only needs to check pre-determined capture values rather than analyzing content sensitivity in real-time, thus reducing operational complexity while maintaining security.
3Object-affected harmful factors
If selective content exclusion is implemented, then information security is improved, but sharing functionality deteriorates
Solution Approach 1:
By segmenting content into shareable and non-shareable elements, the system maintains versatile sharing functionality for safe content while protecting sensitive content. This segmentation approach preserves the adaptability of the screensharing feature by allowing selective sharing rather than completely restricting the functionality.
Solution Approach 2:
The system applies different sharing policies to different elements based on their local characteristics (capture values). This allows the screensharing functionality to adapt to each element's requirements, maintaining high sharing capability for appropriate content while automatically protecting sensitive content, thus preserving overall sharing versatility.

AI summary
A method performed by a computing device comprises, during a screensharing session, determining a capture value of a first element and a capture value of a second element, wherein the capture value of the first element is determined by a provider and the capture value of the second element is determined by the provider, the provider having provided the first element to the computing device and having provided the second element to the computing device; based on the capture value of the first element being shareable, sending content of the first element to the screensharing session; and based on the capture value of the second element being not sharable, excluding content of the second element from the screensharing session.
