Screen Share Confidentiality via Content Summarization

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current screen sharing technologies lack a mechanism to automatically hide confidential or private information during screen sharing sessions, leading to potential unintended disclosure due to user oversight or carelessness.

Innovation Solution

A method that summarizes content to be shared, allowing users to transmit only summarized content instead of full content, with options to expand it upon request, and includes password protection and avatar prompts for secure sharing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If full content is shared during screen sharing, then information completeness is improved, but confidentiality is compromised

Engineering Contradiction:

Improveinformation completenessVSAvoidconfidentiality risk

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The system extracts and transmits only the essential or summarized content from the full screen content during screen sharing, rather than transmitting the complete content. This extraction approach maintains information usefulness while reducing the risk of confidential information exposure.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system changes the parameter of content transmission from full-resolution complete content to summarized or reduced-content representation. This parameter change allows the shared content to convey necessary information while minimizing the exposure of sensitive details.

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If summarized content is transmitted, then confidentiality is improved, but information completeness deteriorates

Engineering Contradiction:

Improveconfidentiality protectionVSAvoidcontent detail

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The system applies partial action by transmitting only a portion or summary of the full content rather than the complete content. This partial transmission protects confidentiality while providing sufficient information for the collaboration purpose.

Inventive Principle:

Principle #16Partial or excessive action

3Object-affected harmful factors

If automatic content analysis is implemented, then confidentiality protection is improved, but system complexity increases

Engineering Contradiction:

Improveautomatic protectionVSAvoidsystem complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The screen sharing system automatically performs content analysis and determines what to summarize or protect without requiring manual user intervention. The system serves itself by autonomously identifying and protecting confidential information while maintaining smooth screen sharing operation.

Inventive Principle:

Principle #25Self-service

AI summary

A method for safeguarding confidential information during a screen share between two computing devices each having a screen. The method includes receiving, from a first computer, a request to share content of one or more applications displayable on a screen of a second computer. The method further includes summarizing the content to be displayed by the one or more applications, and transmitting, by the first computer, the summarized content to be shared by the one or more applications with the second computer. In exemplary embodiments, the summarized content may be password protected. The method may further include prompting, by the second computer, a password entry and displaying, by the second computer, the summarized content based on a password match.
