Vehicle User Authentication Using Driving Behavior and Backend Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle authentication methods are impractical and insecure while the vehicle is in motion, often requiring user attention and lacking sufficient security, especially when using conventional two-factor authentication.
Innovation Solution
A method using a backend server to authenticate users based on vehicle-related data, such as vehicle identifiers and driving behavior, combined with personal data like biometrics, forming a blockchain for secure and efficient two-factor authentication without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional two-factor authentication is used requiring user attention and interaction, then authentication security is improved, but ease of operation deteriorates as it distracts the driver and is impractical while driving
Solution Approach 1:
The authentication system performs verification automatically using vehicle-related data (location, speed, acceleration, steering angle) and personal data stored in the backend server, without requiring the driver's active participation. The vehicle's own operational data serves as authentication credentials, allowing the system to authenticate the driver's identity and authorization status autonomously while the vehicle is in motion.
Solution Approach 2:
The patent replaces manual authentication interactions (typing passwords, entering codes, or actively confirming identity) with automated data collection and analysis. The vehicle's sensors continuously monitor operational parameters and compare them against stored profiles in the backend server, substituting mechanical user actions with automated electronic verification processes.
2Reliability
If conventional two-factor authentication at infrastructure devices is used, then authentication security is improved, but productivity deteriorates by hindering other vehicles waiting at the same infrastructure device
Solution Approach 1:
Authentication data (vehicle-related data and personal data) is pre-collected and stored in the backend server before the vehicle reaches any infrastructure device. The continuous monitoring and verification process begins earlier, allowing authentication to be completed instantly or even preemptively, eliminating queues and delays at toll booths, parking lots, gas stations, or charging stations.
Solution Approach 2:
The authentication process transitions from discrete, event-based verification at infrastructure devices to continuous verification throughout the vehicle's operation. The system continuously collects vehicle operational data, compares it against stored profiles, and maintains authentication status, allowing seamless passage through multiple infrastructure devices without repeated stoppages.
3Reliability
If blockchain is used to secure vehicle-related data, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent introduces a backend server as an intermediary between the vehicle and the blockchain network. The server handles data collection, processing, and storage locally, then selectively interacts with the blockchain for critical authentication verification. This intermediary layer simplifies the vehicle's onboard system complexity while maintaining blockchain-level security for essential authentication data.
