Wearable Linked Display Control for Information Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display techniques fail to effectively prevent information leakage on non-wearable terminals by simply transferring display data to wearable terminals without considering the user's location or surrounding environment, leaving the information vulnerable to unauthorized viewing.
Innovation Solution
An alternative display system that utilizes a wearable terminal and a non-wearable terminal connected via wireless communication, employing sensors and cameras to analyze the environment and user's position, and controls the display state of the non-wearable terminal based on shielding objects, security cameras, and proximity to unauthorized individuals, ensuring secure display data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If display data is transferred from non-wearable terminal to wearable terminal, then information security is improved, but display functionality and usability deteriorate
Solution Approach 1:
The patent applies local quality by selectively applying alternative display control only to specific display areas that require security protection, while other areas maintain normal display functionality. This allows information security to be improved for sensitive content without completely sacrificing display usability, as users can still access non-sensitive information on the non-wearable terminal screen.
Solution Approach 2:
The display screen is segmented into multiple regions: areas requiring security protection (where alternative display is applied) and areas maintaining normal display. This segmentation allows the system to balance information security with display functionality by treating different portions of the display differently based on their security requirements.
2Reliability
If alternative display control is applied to entire screen, then information security is improved, but user convenience and display versatility worsen
Solution Approach 1:
Instead of uniformly applying alternative display control to the entire screen, the patent implements local quality by selectively applying the control only to specific regions where security is needed. This preserves display versatility for other areas while maintaining information security for sensitive content.
Solution Approach 2:
The alternative display control dynamically adjusts based on the surrounding situation and security requirements. The system can flexibly change which areas require alternative display control, adapting to different usage scenarios and maintaining both security and versatility.
3Reliability
If display state is controlled based on surrounding situation, then information security is improved, but device complexity increases
Solution Approach 1:
The system employs sensors and image recognition capabilities to automatically detect surrounding situations and determine when alternative display control should be applied. This self-service approach reduces the need for complex manual control mechanisms while maintaining high information security through automated environmental awareness.
Solution Approach 2:
The system continuously monitors surrounding conditions through sensors and cameras, providing feedback to the control algorithm that adjusts display control accordingly. This feedback mechanism enables adaptive security control without requiring overly complex predetermined control logic.
Data Source
AI summary
From a wearable terminal to a non-wearable terminal, a control signal for causing display data being shown on a display of the non-wearable terminal to be hidden is transmitted based on information about a place or information about an information leakage medium, which causes the display data to be hidden on the display of the non-wearable terminal and also the display data to be transmitted to the wearable terminal. Upon receiving the display data from the non-wearable terminal, the wearable terminal shows the display data on a display provided in the wearable terminal.
