Shutter Glasses Identity Recognition for Confidential Display Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for maintaining confidentiality, such as encrypting files or devices, are vulnerable to cracking and screen photography, leading to potential data leakage when operating confidential files.
Innovation Solution
Shutter glasses with an identity recognition module and a shutter system that controls lens visibility based on authorized wearers, combined with a display device that interposes incoherent interference images between coherent target images, ensuring only authorized individuals can view sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encrypted files or devices are used to maintain confidentiality, then security is improved, but they can be cracked or photographed leading to data leakage
Solution Approach 1:
The patent applies periodic action by using a shutter mechanism that periodically switches between transparent and opaque states at specific timing intervals. The shutter turns on during target image display periods and turns off during interference image display periods, creating a time-based access control system that prevents continuous viewing and screen photography of confidential content.
Solution Approach 2:
The patent uses an intermediary approach by introducing a shutter as a mediating component between the viewer and the display screen. The shutter acts as a controllable barrier that selectively blocks or allows light transmission based on timing signals, serving as a physical intermediary that enforces viewing restrictions without modifying the display content itself.
2Reliability
If a shutter mechanism is used to control lens visibility, then security is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing the shutter mechanism to perform multiple functions: it serves as both a security control element and an integral part of the display system. The same shutter structure that provides security by blocking views also works in conjunction with the display device's timing system, eliminating the need for separate security hardware and reducing overall system complexity.
Solution Approach 2:
The patent merges the shutter control system with the display device's existing timing and signal generation components. The shutter receives control signals from the display device's processor that already exist for synchronizing image display, combining security functionality with existing display operations rather than requiring independent security control hardware.
3Reliability
If interference images are interposed between target images, then security is improved, but image coherence and viewing quality deteriorate
Solution Approach 1:
The patent uses periodic action by displaying target images and interference images in alternating time intervals. The shutter synchronizes with this periodic display pattern, being transparent during target image periods and opaque during interference image periods. This temporal separation ensures that viewers only see coherent target images when the shutter is open, while interference images are blocked, maintaining both security and viewing quality.
Solution Approach 2:
The patent applies segmentation by dividing the display time into distinct segments: target image display periods and interference image display periods. This temporal segmentation allows the system to present different types of content at different times, with the shutter acting as a gate that only allows viewing during the target image segments, thereby maintaining image coherence for legitimate viewers while preventing unauthorized access.
