Video Conference Screen Share Restricted Content Obscuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During video conferencing sessions, there is a risk of accidentally sharing confidential information due to the inability to detect and obscure restricted content in real-time before it is transmitted to other devices.
Innovation Solution
A system that analyzes the display using image and character recognition to identify restricted information before encoding and transmission, allowing for real-time obscuration of such content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If real-time image and character recognition is performed on the display before encoding, then the ability to detect and obscure restricted content is improved, but the processing time and computational complexity increase
Solution Approach 1:
The system performs image and character recognition analysis on the display content before it is encoded and transmitted. This preliminary detection action identifies restricted content in advance, allowing the system to obscure it prior to transmission. The analysis is performed on each frame or sequence of frames captured from the display, enabling real-time prevention of confidential information leakage while maintaining the flow of the video conferencing session.
2Reliability
If continuous monitoring and analysis of display content is performed, then the security against accidental sharing is improved, but the device complexity and computational resources required increase
Solution Approach 1:
The system introduces an intermediary analysis layer between the display output and the encoding process. This intermediary component captures display frames, performs image and character recognition, compares identified content against a database of restricted information, and controls the obscuration process. The intermediary acts as a mediator that prevents restricted content from being encoded and transmitted, adding security without requiring fundamental changes to the core video conferencing architecture.
3Reliability
If obscuration is applied to all detected text and images, then the protection of restricted content is improved, but the usability and clarity of the shared display deteriorates
Solution Approach 1:
The system applies obscuration locally only to the specific regions identified as containing restricted content, rather than obscuring the entire display. After character recognition identifies restricted words or phrases and image recognition identifies restricted images, the system applies obscuration masks or blurring effects only to those specific areas. This localized approach maintains the usability and clarity of the shared display for legitimate content while protecting confidential information.
Solution Approach 2:
The obscuration is applied dynamically based on real-time detection results. When restricted content is detected, the system dynamically applies obscuration to the affected areas and can adjust the obscuration parameters (such as blur intensity or mask coverage) to balance protection with usability. The system can also provide notifications to users about detected restricted content, allowing them to review and adjust obscuration settings as needed.

AI summary
Systems and methods for obscuring images and/or text during a screen sharing operation in a video conferencing session are described herein. In some embodiments, a client device detects a screen sharing operation. As part of the screen sharing operation, the client device captures an image of a display. The client device recognizes images and/or text in the image of the display and determines whether any of the images and/or text are restricted. If the images and/or text are determined to be restricted, the client device obscures the images and/or text prior to encoding of the image of the display for transmission.
