Presence Sensing Security for Computing Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric security systems lack the ability to dynamically adjust security levels based on the presence of authorized or unauthorized users, leading to potential breaches when users temporarily leave their computing devices or engage in confidential activities within view of others.
Innovation Solution
A presence sensing security method that secures access to computing devices by detecting the presence of authorized or unauthorized users using technologies like radio frequency identification tags or smart cards, applying measures such as masking content or encrypting files, and selectively allowing access to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric authentication is used to grant access to computing devices, then user convenience and access speed are improved, but security vulnerability increases when users temporarily leave their devices
Solution Approach 1:
The system dynamically adjusts security measures based on real-time presence detection. When a user is present, full access is granted; when absent, security measures are activated. This dynamic adaptation resolves the contradiction by making security responsive to actual conditions rather than static.
Solution Approach 2:
The system continuously monitors user presence through sensors and adjusts security states accordingly. This feedback mechanism allows the system to automatically respond to changes in user presence, maintaining security without requiring manual intervention while preserving convenience during active use.
2Ease of operation
If full access is granted after biometric validation, then user convenience is improved, but exposure of confidential information to bystanders increases
Solution Approach 1:
The system applies different security measures to different applications and data types. Confidential applications receive enhanced protection through masking or encryption when presence is detected, while non-confidential applications remain fully accessible. This localized application of security resolves the contradiction by protecting only what needs protection.
Solution Approach 2:
The system changes security parameters (such as masking level or encryption state) based on presence detection. When a user is present, normal operation continues; when absent or when bystanders are detected, security parameters are adjusted to prevent information exposure while maintaining user convenience during legitimate use.
3Reliability
If presence detection is implemented to secure computing devices, then security reliability is improved, but system complexity increases
Solution Approach 1:
The system performs presence detection and security adjustments automatically without requiring user intervention. The presence detection module continuously monitors for user presence and the security module automatically applies appropriate measures, making the system self-managing and reducing operational complexity despite enhanced functionality.
4Reliability
If selective security is applied to specific applications, then information security is improved, but access management complexity increases
Solution Approach 1:
The system applies security measures locally to specific applications and data types rather than uniformly across the entire system. Confidential applications are masked or encrypted when presence is detected, while non-confidential applications remain accessible. This selective approach improves information security without requiring complex manual access management.
