Displaying sensitive information exposes a surface different from file access. Design and describe mirroring and recording controls within the platform's actual limits.
Evaluation approach
Test supported capture states and sensitive-view behavior separately. Include previews generated when the application enters the background.
Application example
While a health report is displayed, define which content remains visible if sharing state changes.
Limits and considerations
One screen signal cannot cover every recording method. External cameras remain outside application control.
Reduce the information displayed
Screen-recording defenses depend on the platform and usage conditions. Showing less sensitive data initially can reduce the impact if capture occurs. Include notification previews and task-switcher images in the review.
Provide a secure workflow for legitimate remote-support needs. Interrupting every form of sharing based on one signal can disrupt support. Explicitly recognize that external recording methods may remain outside the application's control.
Checks and decisions
- Verify platform support
- Classify sensitive views
- Test state changes
Explain which visual channels are restricted instead of promising complete confidentiality.
