Selective Data Masking in Virtual Presentations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual conferences, sensitive information is often inadvertently shared with all participants, compromising confidentiality and security, as existing technologies lack effective mechanisms to selectively mask or hide such data based on viewer characteristics.
Innovation Solution
A system and method that generate a dictionary of sensitive terms, decision trees for participant validation, and a display matrix to determine and mask sensitive information dynamically, using speech-to-text algorithms and pixel manipulation to ensure only authorized viewers access sensitive content during presentations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all presentation content is displayed to all participants, then complete information access is provided, but sensitive information confidentiality is compromised
Solution Approach 1:
The patent applies local quality by masking specific portions of the presentation content based on participant characteristics. Instead of uniformly displaying or hiding all content, the system selectively masks only the sensitive portions relevant to each participant's role, allowing authorized participants to view sensitive information while preventing unauthorized access to specific local regions of the content.
Solution Approach 2:
The system performs preliminary action by pre-classifying presentation content into sensitive and non-sensitive categories before the presentation begins. The content is tagged with sensitivity metadata and participant characteristic requirements in advance, enabling the masking system to automatically determine what to hide based on pre-established rules rather than making real-time decisions during the presentation.
2Loss of information
If sensitive data is masked for all participants, then confidentiality is maintained, but authorized participants cannot access necessary information
Solution Approach 1:
The system implements feedback by continuously monitoring participant characteristics (such as role, department, or security clearance level) and comparing them against the sensitivity requirements of each content element. This feedback loop enables the system to dynamically adjust masking decisions, ensuring that authorized participants receive the information they need while unauthorized participants see appropriate restrictions.
Solution Approach 2:
The patent applies parameter changes by varying the masking state of content based on participant parameters such as role, department, or security clearance. The system changes the display parameter (masked vs. unmasked) dynamically according to the intersection of content sensitivity requirements and participant authorization levels, ensuring accurate information delivery.
3Loss of information
If dynamic masking is implemented based on participant characteristics, then information security is enhanced, but system complexity increases
Solution Approach 1:
The system applies segmentation by dividing the presentation content into discrete, independently maskable elements with associated sensitivity metadata. Each content element can be individually tagged and controlled, allowing the masking system to operate on a granular level without requiring complex global processing. This segmentation simplifies the overall system architecture by breaking down the masking problem into manageable, independent decisions.
4Adaptability or versatility
If content is classified and tagged before presentation, then selective display is enabled, but preparation time and processing complexity increase
Solution Approach 1:
The system performs preliminary action by automatically classifying and tagging presentation content with sensitivity metadata during the content creation or upload phase. This pre-processing step establishes the foundation for dynamic masking without requiring manual intervention during the actual presentation, reducing preparation time for the masking functionality itself.
