Measurement Result Verification Using Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing measurement results from measuring instruments, such as tablet testers, are vulnerable to manipulation after being exported or printed, lacking effective verification methods to ensure authenticity.
Innovation Solution
Implementing a verification procedure that requires biometric authentication of users before and after measurement, storing biometric data in user management software, and comparing these data to ensure the same user is processing the results, thereby preventing unauthorized manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If measurement results are exported or printed to external devices, then ease of operation is improved, but reliability deteriorates due to vulnerability to manipulation
Solution Approach 1:
The system performs preliminary actions by capturing biometric data of the user before the measurement process begins and storing it in the measuring device. This preliminary biometric authentication ensures that the same user who initiated the measurement is the one accessing the results, preventing unauthorized manipulation while allowing seamless export and printing operations.
Solution Approach 2:
The system implements a feedback mechanism by capturing biometric data again after measurement completion and comparing it with the stored biometric data. This feedback loop verifies user identity and detects any unauthorized access attempts, ensuring reliability while maintaining ease of operation for legitimate users.
2Reliability
If biometric authentication is implemented before and after measurement, then reliability is improved, but device complexity increases
Solution Approach 1:
The measuring device integrates multiple functions including measurement capabilities, biometric data capture, biometric data storage, and biometric data comparison within a single system. This multi-functionality approach consolidates what could be separate complex systems into one unified device, improving reliability without proportionally increasing overall complexity.
Solution Approach 2:
The measuring device performs self-verification by automatically comparing the captured biometric data with the stored biometric data without requiring external verification systems. This self-service capability enhances reliability while minimizing the need for additional complex external components.
