Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle authentication systems lack the ability to accurately determine a user's position relative to the vehicle during biometric authentication, which is essential for secure control operations.
Innovation Solution
An authentication system that combines key authentication through wireless communication with biometric authentication using detectors at various locations, allowing the controller to actuate onboard devices based on the user's position, ensuring secure vehicle control by verifying the authenticity of key information and biological data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric authentication is implemented to improve security, then authentication security is improved, but the system cannot determine user position relative to the vehicle
Solution Approach 1:
The patent combines key authentication (wireless communication) and biometric authentication (detector-based) into a unified authentication system. The controller integrates both authentication results to determine final access authorization, merging two different authentication modalities to simultaneously achieve high security and position awareness.
Solution Approach 2:
The patent divides the authentication system into separate functional modules: key authentication unit for wireless credential verification, detectors at different locations for biometric detection, and controller for integrating results. This segmentation allows each component to specialize in its function while the system as a whole achieves both security and position detection.
2Measurement precision
If detectors are placed at multiple locations to detect user position, then position detection capability is improved, but device complexity increases
Solution Approach 1:
The detectors serve dual functions: they detect biological information for biometric authentication and simultaneously provide position information based on their fixed locations. This multi-functionality eliminates the need for separate position detection sensors, reducing overall system complexity while maintaining accurate position detection.
Solution Approach 2:
The system uses the detectors' inherent positional information (their fixed locations on the vehicle) to determine user position without requiring additional complex positioning infrastructure. The detectors self-identify their locations and use this information to infer user position based on which detector detects the biological signal.
3Reliability
If both key authentication and biometric authentication are required, then authentication security is improved, but authentication time increases
Solution Approach 1:
The system performs key authentication first as a preliminary step before biometric authentication. This preliminary action filters out unauthorized users early in the process, so that only legitimate users proceed to the more time-consuming biometric verification, thereby reducing overall authentication time while maintaining high security.
Solution Approach 2:
The controller uses feedback from the key authentication result to determine whether to proceed with biometric authentication. If key authentication fails, the system immediately terminates the authentication process, avoiding unnecessary biometric verification time. This feedback mechanism optimizes authentication time based on intermediate results.

Data Source
AI summary
An authentication system includes a terminal and a key authentication unit arranged in a communication peer that communicates with the terminal. The key authentication unit receives key information of the terminal carried by a user through wireless communication and performs key authentication that verifies authenticity of the key information. The authentication system further includes detectors that are arranged at different locations and detect biological information of the user and a biometric authentication unit that uses the biological information to perform biometric authentication. The authentication system further includes a controller that controls actuation of the communication peer based on a location of one of the detectors that detected the biological information, an authentication result of the key authentication, and an authentication result of the biometric authentication.
