Screen Sensitive Information Masking via Light Sensor Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to effectively protect personal sensitive information displayed on electronic device screens from being easily spied by others, leading to information leakage and security issues.
Innovation Solution
A method and apparatus that utilize a light sensor to monitor light intensity thresholds, identifying and masking sensitive information areas on the screen when light intensity increases above a first threshold, and unmasking when it decreases below a second threshold, using techniques such as displaying a rectangular picture or adjusting background colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sensitive information is displayed directly on the screen, then information accessibility is improved, but information security deteriorates
Solution Approach 1:
The patent implements dynamic screen content adjustment based on detected light intensity. The processing unit dynamically masks or unmask s sensitive information areas by generating masked screen content when light intensity exceeds the threshold and displaying original content when it does not, allowing the system to adapt between security and accessibility states based on environmental conditions
Solution Approach 2:
The patent applies visual masking by rendering rectangular pictures or adjusting background colors in sensitive information areas. The display unit presents obscured content through color changes or overlay graphics when masking is activated, making sensitive information visually indistinguishable while maintaining the underlying data structure
2Object-affected harmful factors
If light intensity monitoring and masking is implemented, then information security is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into existing device components. The light sensor performs its primary function of detecting ambient light for display brightness adjustment while simultaneously detecting light intensity for security masking decisions. The processing unit handles both normal display content generation and security masking operations, reducing the need for dedicated separate components
Solution Approach 2:
The system uses the device's existing light sensor and processing capabilities to automatically monitor light intensity and adjust screen content masking without requiring external monitoring devices or complex additional hardware. The device serves its own security monitoring needs using already-present components
