Contextual Browser Tab Screenshot Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing app protection solutions apply protection globally across all browser tabs, failing to provide individualized protection based on the classification of each browser tab as corporate or personal.
Innovation Solution
A computing device with a processor that classifies selected browser tabs based on their addresses and enables app protection to selectively block screenshots only for corporate apps, allowing personal apps to be screenshotted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If global app protection is applied to all browser tabs, then corporate data security is improved, but personal app accessibility deteriorates
Solution Approach 1:
The patent segments browser tabs into corporate and personal categories based on URL classification. App protection is then applied selectively to corporate tabs while leaving personal tabs unrestricted. This segmentation resolves the contradiction by dividing the uniform protection approach into differentiated protection levels based on tab type.
Solution Approach 2:
The patent implements local quality by applying different protection properties to different browser tabs. Corporate tabs receive screenshot blocking protection while personal tabs maintain normal functionality. The system dynamically adjusts protection based on the specific tab's classification, ensuring that protection is applied only where needed rather than uniformly across all tabs.
2Object-affected harmful factors
If app protection blocks screenshots for all tabs, then data leakage prevention is improved, but user convenience deteriorates
Solution Approach 1:
The patent applies screenshot blocking protection only to corporate browser tabs while leaving personal tabs unrestricted. The system classifies each tab based on its URL and selectively enables protection measures only where corporate data is present, thereby preventing data leakage in critical areas without impacting user convenience for personal applications.
Solution Approach 2:
The patent segments the browser environment into protected and unprotected zones based on tab classification. Corporate tabs are identified and placed in the protected zone with screenshot blocking enabled, while personal tabs remain in the unprotected zone with full functionality. This segmentation allows data leakage prevention without compromising overall user convenience.
3Measurement precision
If contextual tab classification is implemented, then protection precision is improved, but system complexity increases
Solution Approach 1:
The patent changes the parameter used for protection decisions from a uniform global setting to a tab-specific classification parameter. By monitoring and classifying each tab's URL, the system achieves precise protection targeting. The complexity introduced by URL monitoring and classification is offset by the precision gained in applying protection only to relevant corporate tabs.
Data Source
AI summary
A computing device includes a display, and a browser to access applications for display in a browser window. Each application is associated with a respective browser tab within the browser window. A processor is coupled to the display to display content from an application associated with a selected browser tab, and to classify the selected browser tab. The processor enables app protection to selectively block screenshots of the displayed content based on the classification of the selected browser tab.
