Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional privacy filters for electronic displays either fail to prevent unauthorized viewing or compromise the authorized user's experience by reducing viewing angles and brightness, and are vulnerable to hacking using static polarization filters.
Innovation Solution
A dynamic privacy system that uses a unique identifier to dynamically adjust the polarization of the display and a corresponding filter on a viewing aid, continuously changing the polarization angle to prevent unauthorized access, while maintaining flexibility and security for the authorized user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a static privacy filter is used to prevent unauthorized viewing, then security is improved, but viewing angles and brightness are reduced
Solution Approach 1:
The patent applies dynamics by transitioning from static polarization filters to dynamic polarization control. The display device continuously changes the polarization angle of emitted light based on user position detection, while the viewing aid dynamically adjusts its filter orientation to match. This dynamic adaptation maintains brightness and viewing angles by only blocking light from unauthorized directions rather than uniformly reducing all light transmission.
Solution Approach 2:
The system changes the polarization parameter of emitted light dynamically. The display controller adjusts the polarization angle as a variable parameter based on detected user position, and the viewing aid correspondingly adjusts its filter's polarization orientation. This parameter change enables selective light transmission that maintains brightness for authorized users while preventing unauthorized viewing.
2Reliability
If a privacy filter is applied to block unauthorized viewing, then security is improved, but viewing flexibility is reduced
Solution Approach 1:
The system uses dynamic polarization adjustment to maintain viewing flexibility. The display detects user position and continuously adapts the polarization angle, allowing the authorized user to view content from various angles. The viewing aid similarly adapts its filter orientation, ensuring the user experience remains flexible while security is maintained through dynamic rather than static filtering.
Solution Approach 2:
The system implements feedback through position detection. The display device detects the user's viewing position and uses this feedback to adjust the polarization angle accordingly. This closed-loop feedback mechanism ensures that security measures adapt to actual usage patterns, maintaining viewing flexibility while preventing unauthorized access.
3Reliability
If a static polarization filter is used for privacy, then unauthorized viewing is prevented, but the system becomes vulnerable to hacking
Solution Approach 1:
The patent counters hacking vulnerability by implementing dynamic polarization changes. Since the polarization angle continuously varies based on user position rather than remaining static, unauthorized users cannot use fixed polarization filters to bypass the privacy protection. The dynamic adaptation creates a moving target that defeats static exploitation attempts.
Solution Approach 2:
The system employs periodic action by continuously cycling through different polarization angles based on detected user position. This periodic variation in polarization orientation prevents unauthorized viewing while maintaining user access, as the filter settings are constantly updated rather than remaining fixed, thereby preventing exploitation.
