Video Session Privacy Controller for Secondary Content Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During video communication sessions, participants may have secondary content, such as confidential documents or personal items, inadvertently captured and transmitted within the image stream, which they prefer to keep private.
Innovation Solution
A communication device equipped with an image capturing device and a controller that identifies secondary content within the image stream, generates a modified stream excluding the secondary content, and transmits this modified stream to other participants during the video communication session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the image capturing device captures the full field of view including surrounding surfaces, then the video communication session provides complete visual context, but secondary content such as confidential documents or personal items may be inadvertently transmitted
Solution Approach 1:
The system extracts and removes secondary content from the image stream while preserving the rest of the visual context. The controller identifies secondary content displayed on surfaces within the field of view and generates a modified image stream that excludes this content, thereby separating the harmful element from the useful visual information.
Solution Approach 2:
The system applies different processing quality to different regions of the image stream. Areas containing secondary content are modified or removed, while other areas maintain their original quality. This allows selective protection of privacy-sensitive regions while preserving overall visual context.
2Object-affected harmful factors
If the controller processes the image stream to remove secondary content, then privacy is maintained, but device complexity increases
Solution Approach 1:
The system performs self-service by automatically identifying and removing secondary content without requiring manual intervention. The controller continuously monitors the image stream, detects secondary content displayed on surfaces, and autonomously generates modified streams, reducing the need for user action while maintaining privacy.
Solution Approach 2:
The system replaces manual privacy management with automated image processing. Instead of requiring users to manually adjust camera angles or inform participants about background content, the controller uses automated detection and processing to manage privacy, substituting mechanical/user intervention with electronic automation.
3Object-affected harmful factors
If the system generates a modified image stream excluding secondary content, then privacy is preserved, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary identification of secondary content in the image stream before final transmission. By detecting and marking areas containing secondary content early in the processing pipeline, the system can prepare modified image streams more efficiently, reducing overall processing time compared to post-processing approaches.

AI summary
A communication device, computer program product, and method are provided that generate an image stream to be transmitted from one communication device to at least another communication device in a video communication session. A controller (i) identifies, within a first image stream, secondary content displayed within at least one surface included in a first field of view, and (ii) in response to identifying the secondary content displayed within the at least one surface (a) generates a second image stream that does not include at least a portion of the secondary content; and (b) transmits the second image stream in place of the first image stream to the at least one second communication device during the video communication session.
