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

VSEngineering 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

Engineering Contradiction:
Improvedriver authentication capabilityVSAvoidvehicle system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If biometric data checking is performed within the vehicle, then authentication speed is improved, but manipulation risk increases

Engineering Contradiction:
Improveauthentication speedVSAvoidmanipulation risk
Core Design Contradiction:
SpeedVSObject-affected harmful factors

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.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If centralized external verification is implemented, then manipulation resistance is improved, but system complexity increases

Engineering Contradiction:
Improvemanipulation resistanceVSAvoidsystem architecture complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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).
