Vehicle Authentication Switching When Biometric Access Fails
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Biometric authentication systems may fail when registered biometric information cannot be used, preventing the switching OFF of the biometric authentication function, leading to inconvenience and potential security risks.
Innovation Solution
An authentication device that performs biometric and identification information authentication, allowing the biometric authentication function to be switched OFF when either authentication succeeds, and provides notifications to the user about the status of the biometric authentication function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is used to improve security, then security against theft is improved, but the system cannot be switched OFF when registered biometric information cannot be used
Solution Approach 1:
The system changes the authentication parameter from biometric-only to alternative authentication methods (mobile device identification, other biometric types) when the registered biometric information cannot be used, allowing the authentication function to be switched OFF while maintaining security
Solution Approach 2:
The authentication system dynamically adapts by switching between different authentication methods based on the usability of registered biometric information, enabling the function to be turned OFF when biometric data is unavailable while maintaining operational flexibility
2Reliability
If only unusable specific biometric information is registered, then biometric authentication fails, but the authentication function cannot be switched OFF
Solution Approach 1:
The system dynamically detects when registered biometric information is unusable and automatically enables alternative authentication pathways, allowing the authentication function to be switched OFF while maintaining system adaptability
Solution Approach 2:
When biometric authentication fails due to unusable registered information, the system changes to alternative authentication parameters (mobile device ID, other biometric types), enabling users to switch OFF the authentication function while preserving system versatility
3Reliability
If biometric authentication is required for all operations, then security is improved, but user convenience deteriorates when biometric information cannot be used
Solution Approach 1:
The system dynamically switches between biometric and alternative authentication methods based on usability, maintaining security while improving user convenience when biometric information cannot be used
Solution Approach 2:
The system changes authentication parameters from biometric-only to alternative methods when biometric information is unusable, maintaining security requirements while improving user convenience through flexible authentication options
Data Source
AI summary
An authentication device to be mounted on a vehicle includes a processor. The processor is configured to execute first authentication based on biometric information acquired from a user and biometric information preregistered in the vehicle. The processor is configured to execute second authentication different from the first authentication. The processor is configured to transit setting of the first authentication to a state in which the user is able to change the setting, when the second authentication is successful.
