Screen Share Frame Processing for Real-Time Sensitive Data Masking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for masking sensitive information during a screen share session of a video call are limited to pre-identified sensitive information and cannot effectively handle real-time or near real-time identification and masking of sensitive information in various types of content, such as web pages, handwritten documents, or unmarked content.
Innovation Solution
The technique involves adjusting the frame rate of the video stream to allow for real-time processing of video frames, extracting text using OCR or other services, searching for patterns or indicators of sensitive information, and modifying the frames to mask the identified sensitive information before transmission to the recipient device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video stream processing is performed in real-time to identify and mask sensitive information, then data privacy and security are improved, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary actions by adjusting the video stream frame rate before processing begins, ensuring that frames are delivered at a manageable pace for real-time analysis. This preliminary adjustment of the video stream parameter enables the processing system to handle sensitive information identification and masking without being overwhelmed by excessive frame rates, thus improving data privacy while maintaining manageable system complexity
Solution Approach 2:
The processing system segments the video stream into individual frames for sequential analysis. Each frame is processed independently to identify sensitive information patterns, apply masking operations, and then reassemble into the final video output. This segmentation approach allows the system to maintain real-time processing capability while managing complexity through modular frame-by-frame handling rather than attempting to process the entire video stream simultaneously
2Reliability
If video frame processing is performed to mask sensitive information, then sensitive information protection is improved, but video stream delay increases
Solution Approach 1:
The system changes the temporal parameter of the video stream by adjusting the frame rate to a lower value before processing begins. This parameter adjustment creates a time buffer that allows sufficient processing time for sensitive information identification and masking operations to be completed on each frame before it needs to be displayed, thereby protecting sensitive information while minimizing the perceived delay in the video stream
3Adaptability or versatility
If real-time video stream processing is implemented, then sensitive information masking capability is improved, but processing speed requirements increase
Solution Approach 1:
The system performs preliminary action by pre-adjusting the video stream frame rate to a lower value before real-time processing begins. This preliminary speed adjustment ensures that incoming frames are delivered at a pace that allows the processing system sufficient time to perform sensitive information identification, pattern matching, and masking operations, thereby achieving versatile masking capability across different content types while maintaining feasible processing speed requirements
