AI Driver Re-Authentication Using Vehicle Speed-Adaptive Checks

Solution Overview

Problem

Current digital-key-based driver authentication systems pose safety threats while the vehicle is moving and do not effectively prevent unauthorized use, especially in car-sharing scenarios where digital keys can be shared or stolen.

Innovation Solution

An electronic device mounted on a vehicle uses an AI-based authentication process, including a first authentication module to determine valid users, a control module to select between low-speed and high-speed authentication processes based on vehicle speed, and a second authentication module to re-authenticate drivers safely, thereby preventing unauthorized vehicle use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If digital-key-based driver authentication is used, then driver authentication is simplified and can be performed based on body motion, but safety threats arise while the vehicle is moving and unauthorized use cannot be prevented

Engineering Contradiction:

Improvedriver authenticationVSAvoidauthentication security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs repeated authentication checks at predetermined time intervals during vehicle operation. The authentication module continuously validates the driver's identity by processing sensing data periodically, ensuring that unauthorized use is detected and prevented while maintaining convenient operation throughout the journey

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses sensing data from sensors to provide continuous feedback about the driver's identity and authentication status. This feedback loop allows the system to detect changes in driver identity and respond by re-authenticating or alerting authorized users, thereby maintaining security without compromising ease of operation

Inventive Principle:

Principle #23Feedback

2Measurement precision

If biometric identification is used for driver authentication, then authentication accuracy is improved, but the system is vulnerable to theft and cannot block drivers who change after initial authentication

Engineering Contradiction:

Improveauthentication accuracyVSAvoidauthentication security

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The system performs repeated authentication checks at predetermined time intervals during vehicle operation. The authentication module continuously validates the driver's identity by processing sensing data periodically, ensuring that unauthorized use is detected and prevented while maintaining convenient operation throughout the journey

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system establishes baseline authentication criteria during initial biometric identification and then uses these criteria to perform preliminary checks before allowing vehicle operation. This preliminary authentication framework enables the system to quickly verify driver identity changes without requiring full re-authentication, balancing security with operational efficiency

Inventive Principle:

Principle #10Preliminary action

3Reliability

If repeated authentication is implemented to prevent unauthorized use, then authentication security is improved, but system complexity and processing time increase

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs repeated authentication checks at predetermined time intervals during vehicle operation. The authentication module continuously validates the driver's identity by processing sensing data periodically, ensuring that unauthorized use is detected and prevented while maintaining convenient operation throughout the journey

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system uses existing sensors already present in the vehicle to collect authentication data, eliminating the need for separate authentication hardware. By leveraging existing sensing capabilities and processing power, the system achieves repeated authentication without significantly increasing device complexity or processing burden

Inventive Principle:

Principle #25Self-service
