Mobile Screen Privacy Protection via Dynamic Luminance Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for protecting screen privacy on mobile devices are either costly, complex, or inconvenient, as they require hardware modifications, external films, or software solutions that disrupt the user experience by reducing screen readability.
Innovation Solution
A software-based method that uses environmental data acquisition, human face recognition, and image processing to determine the privacy exposure state of a user, adjusting screen luminance, color, and font size to protect information from unauthorized viewers without hardware additions, ensuring readability for the user within a defined security region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a privacy protection display screen is used, then screen privacy is protected, but the cost increases and hardware modification is required
Solution Approach 1:
The patent replaces the mechanical hardware solution (privacy protection display screen) with a software-based system that uses the camera, sensors, and display control to achieve privacy protection. The software analyzes environmental data and camera images to detect peepers and dynamically adjusts screen parameters, eliminating the need for specialized hardware.
2Reliability
If a privacy protection film is attached externally, then screen privacy is protected, but the screen definition is reduced and the film needs to be carried separately
Solution Approach 1:
Instead of using a physical film that degrades screen quality, the patent creates a virtual privacy protection mechanism through software. The system captures images with the camera, analyzes them to detect unauthorized viewers, and controls the display to protect information, effectively copying the privacy protection function from physical film to software-based detection and control.
3Reliability
If software uses camera for background monitoring, then screen privacy is protected, but the user reading experience is reduced and convenience decreases
Solution Approach 1:
The patent implements dynamic privacy protection that adapts to the viewing situation. The system continuously monitors the environment and only activates privacy protection when a peeper is detected. It dynamically adjusts screen parameters such as brightness, contrast, and content visibility based on the detected threat level, allowing normal reading experience when no threat is present while providing protection when needed.
