Screen Sharing Mosaic for Privacy Protection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing screen sharing technologies fail to adequately protect privacy, as they lack a frame for camera images, leading to unintended confidential information being shared.

Innovation Solution

A computer system and method that allows users to input a predetermined area on the screen for privacy protection by performing a mosaic process, which obscures the selected area or areas from the sharing destination, preventing visual recognition.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If screen sharing is performed without a window frame for camera images, then sharing flexibility is improved, but privacy protection deteriorates

Engineering Contradiction:

Improvesharing flexibilityVSAvoidprivacy protection

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The screen is divided into multiple regions: a first region displaying camera images without mosaic processing for sharing flexibility, and a second region displaying applications with window frames for privacy protection. This segmentation allows different areas to serve different purposes - the camera region remains flexible while the application region protects privacy through structured framing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different quality characteristics are applied to different regions of the screen. The first region (camera images) maintains high visual quality without mosaic effects to ensure sharing flexibility, while the second region (applications) incorporates window frames and mosaic processing to provide privacy protection. Each region has optimized properties suited to its specific function.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If mosaic processing is applied to the entire screen, then privacy protection is improved, but information sharing quality deteriorates

Engineering Contradiction:

Improveprivacy protectionVSAvoidinformation sharing quality

Core Design Contradiction:

Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The screen is segmented into a first region for camera images and a second region for applications. Mosaic processing is selectively applied only to the second region where privacy protection is needed, while the first region remains clear to maintain information sharing quality. This prevents unnecessary information loss in the camera image area.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Mosaic processing intensity and application are localized to specific regions. The first region maintains high visual fidelity without mosaic effects for quality information sharing, while the second region applies mosaic processing to protect privacy. This local differentiation ensures privacy protection is applied only where necessary without degrading overall information sharing quality.

Inventive Principle:

Principle #3Local quality

AI summary

A computer system receives an input of a predetermined area within a screen which is screen-shared, and performs a mosaic process so as to cause a sharing destination not to visually recognize either the predetermined area or an area within the screen other than the predetermined area. The computer system extracts and stores a character or an image of a part on which the mosaic process is performed by receiving the input, and performs, when it is displayed on the screen, the mosaic process on it in addition to either the predetermined area or an area within the screen other than the predetermined area.
