Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

During web-based collaboration sessions, there is a need to selectively share desktop content while preserving confidential information, as existing technologies fail to effectively exclude sensitive information from being accessed by attendee devices.

Innovation Solution

The method involves a presenter device sharing desktop content with an attendee device while using a sliding type of window to detect and exclude private content from being displayed, utilizing a system with modules for window detection, rendering, modification monitoring, and control to ensure sensitive information remains private.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the presenter shares the entire desktop during a collaboration session, then the completeness of information sharing is improved, but the confidentiality of sensitive information deteriorates

Engineering Contradiction:

Improvecompleteness of information sharingVSAvoidexposure of sensitive information

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The desktop is segmented into multiple regions: shareable content areas and private content areas. The system divides the display space so that different portions can have different sharing permissions, allowing the presenter to share specific regions while keeping others private during the collaboration session.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the desktop are assigned different quality attributes regarding information sharing. The shareable content area is configured with transparent/sharable properties while the private content area is configured with opaque/private properties, allowing selective information disclosure based on location.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If the presenter excludes sensitive information from sharing, then the confidentiality of private information is improved, but the completeness of shared content deteriorates

Engineering Contradiction:

Improveconfidentiality of private informationVSAvoidcompleteness of shared content

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The desktop display is segmented into distinct shareable and private zones. This segmentation allows the system to exclude only the necessary sensitive portions from sharing while maintaining the sharing of all non-sensitive content, thus preserving overall completeness while ensuring confidentiality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system extracts and isolates only the sensitive information portions from the overall desktop content. By taking out only the confidential elements and placing them in a private area, the rest of the content remains fully shareable, maintaining completeness of shared information while protecting privacy.

Inventive Principle:

Principle #2Taking out (Extraction)

3Measurement precision

If the system monitors modifications to detect private content, then the accuracy of sensitivity detection is improved, but the system complexity deteriorates

Engineering Contradiction:

Improveaccuracy of sensitivity detectionVSAvoidsystem complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary actions by pre-configuring the desktop layout with designated shareable and private areas before the collaboration session begins. This preliminary segmentation reduces the need for complex real-time monitoring and analysis during the session, as the sensitivity detection is based on pre-established spatial boundaries rather than complex content analysis.

AI summary

In one embodiment, the methods and apparatuses include: selectively sharing desktop content with an attendee device wherein the desktop content includes a shared window and a sliding type of window; displaying the desktop content including the sliding type of window on the presenter device; detecting a modification to the desktop content that is beneath the sliding type of window wherein the modification is performed by the attendee device; and excluding the sliding type of window from the desktop content for display on the attendee device.
