Videoconference Content Verification to Prevent Sensitive Screen Sharing

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

During videoconferences, participants may inadvertently share personal or confidential information when sharing their entire desktop, as existing systems lack the ability to verify and control the content being shared.

Innovation Solution

Implementing a content verification presentation on a content presentation companion device or augmented reality companion device before sharing, allowing participants to confirm the content to be shared, ensuring only authorized information is revealed to others.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a participant shares their entire desktop during a videoconference, then content sharing is simple and efficient, but personal or confidential information may be inadvertently revealed

Engineering Contradiction:

Improvecontent sharing simplicityVSAvoidaccidental revelation of sensitive information

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system presents a content verification presentation before actual sharing occurs, allowing the participant to review and confirm the content that will be shared. This preliminary verification step prevents accidental revelation of sensitive information while maintaining the simplicity of the sharing process, as the user simply needs to confirm the previewed content.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A content verification presentation acts as an intermediary between the desktop content and the sharing process. This intermediary layer allows users to preview and verify content before it is actually shared with other participants, preventing inadvertent disclosure of personal or confidential information while preserving ease of use.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a content verification presentation is implemented before sharing, then privacy and control over shared content are improved, but the sharing process becomes more complex

Engineering Contradiction:

Improveprivacy control over shared contentVSAvoidcontent sharing process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The content verification presentation leverages existing videoconference infrastructure and display devices, making it a universal solution that works across different platforms without requiring specialized hardware. By using the same display and processing capabilities already present in the system, the verification feature adds privacy control without proportionally increasing complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Productivity

If desktop content is shared during videoconference, then collaboration and information sharing are enhanced, but sensitive or confidential documents may become visible to other participants

Engineering Contradiction:

Improvecollaboration efficiencyVSAvoidexposure of sensitive or confidential information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The system performs a preliminary verification step by presenting a summary or preview of the content to be shared before actually sharing it. This allows users to confirm that sensitive or confidential documents will not be inadvertently exposed, maintaining collaboration efficiency while preventing information loss through accidental disclosure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The content verification presentation provides feedback to the user about what content will be shared, allowing them to adjust their selection before sharing occurs. This feedback mechanism ensures that sensitive or confidential information is not exposed to other participants while maintaining the productivity benefits of desktop sharing.

Inventive Principle:

Principle #23Feedback

AI summary

A method in a conferencing system terminal device includes detecting, with one or more processors during a videoconference, a communication device electronically in communication with both a content presentation companion device having a display and one or more remote electronic devices engaged in the videoconference. User input requesting for content to be shared from the conferencing system terminal device with the one or more remote electronic devices engaged in the videoconference is received. Prior to causing the communication device to share the content with the one or more remote electronic devices during the videoconference the one or more processors present, on the display of the content presentation companion device, a content verification presentation and receive a content share confirmation in response to the content verification presentation.
