External Driver Authentication via Biometric Data Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle authentication systems face challenges in ensuring efficient and reliable driver authentication, as they often require biometric checking units in every vehicle, which can be manipulated and are not universally applicable, lacking a centralized verification process.
Innovation Solution
A method where a detection device in the vehicle records actual driver data and transmits it to an external station for comparison with stored target data, enabling a release signal only upon matching data, thus allowing the vehicle to start, incorporating biometric and additional authentication methods for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric checking units are installed in every motor vehicle, then driver authentication capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the authentication checking function from the vehicle and relocates it to an external server. The vehicle only retains the detection device for capturing biometric data, while the complex verification process is performed externally. This resolves the contradiction by maintaining authentication capability while significantly reducing in-vehicle system complexity.
Solution Approach 2:
The patent introduces an external server as an intermediary between the vehicle's detection device and the authentication decision. This mediator handles the complex biometric verification process, allowing the vehicle to maintain simple hardware while achieving reliable authentication through the intermediary's processing capabilities.
2Speed
If biometric data checking is performed within the vehicle, then authentication speed is improved, but manipulation risk increases
Solution Approach 1:
The patent extracts the vulnerable biometric data checking process from the vehicle environment and moves it to a secure external server. This physical separation removes the vehicle's internal systems from the attack surface, preventing manipulation while maintaining authentication speed through efficient data transmission and processing.
3Reliability
If centralized external verification is implemented, then manipulation resistance is improved, but system complexity increases
Solution Approach 1:
The patent extracts the complex verification logic from the vehicle and concentrates it in a centralized external server. This approach improves manipulation resistance by securing the verification process outside the vehicle while managing system complexity through standardized communication protocols and modular architecture.
Solution Approach 2:
The external server provides universal authentication services that can serve multiple vehicles and potentially multiple functions. This multi-functionality amortizes the system complexity across many uses, making the centralized approach more efficient and manageable.

AI summary
The invention relates to a method for authenticating a driver (2) in a motor vehicle (1) by means of a recognition device (10) disposed in the motor vehicle (1) for collecting actual data (50) of the driver (2) which are transmitted during the authentication to a checking device (20) disposed in an external station (3) outside the motor vehicle (1), wherein the checking device (20) compares the actual data (50) with the target data (60) and in the event of conformity of the actual data (50) with the target data (60) an enabling signal (70) is sent from the external station (3) to the motor vehicle (1), thus enabling the driver (2) to start the motor vehicle (1).
