Biometric Vehicle Access Authentication for Lost-Key Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle key systems, both physical and digital, suffer from security vulnerabilities, with physical keys being easily lost and digital keys allowing unauthorized access due to reliance on identifier information alone, leading to compromised vehicle security.
Innovation Solution
A vehicle control method utilizing biometric information in conjunction with identifier information to generate unique verification keys, ensuring that both the terminal device and user biometrics are authenticated before vehicle access is granted, thereby enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a digital vehicle key based on terminal device identifier information is used, then vehicle access convenience is improved, but vehicle security deteriorates due to unauthorized access risks
Solution Approach 1:
The authentication system is segmented into two independent parts: terminal device identifier information and user biometric information. Both segments are required for successful authentication, meaning that compromising one segment alone is insufficient for unauthorized access. This segmentation resolves the contradiction by maintaining convenience through terminal device recognition while adding security through biometric verification.
Solution Approach 2:
The system merges two authentication mechanisms (terminal device identification and biometric recognition) into a unified authentication flow. The terminal device provides convenient access initiation, while biometric information provides security verification. This merging allows the system to achieve both ease of operation and reliability simultaneously.
2Reliability
If biometric information authentication is added to terminal device authentication, then vehicle security is improved, but authentication complexity increases
Solution Approach 1:
The biometric authentication leverages the terminal device's existing self-service capabilities for biometric collection and processing. The terminal device itself performs biometric verification without requiring external authentication servers or additional hardware, thus improving security while minimizing the increase in system complexity.
Solution Approach 2:
The terminal device is designed to perform multiple functions: it serves as both the authentication request initiator (providing device identifier) and the biometric verification system. This multi-functionality allows biometric authentication to be integrated without adding separate complex authentication infrastructure, thereby improving security with minimal complexity increase.

AI summary
This disclosure provide a vehicle control method. A first terminal device obtains first biometric information of a first user, generates a first key based on the first biometric information and identifier information of the first terminal device, and generates first verification information based on the first key. Further, the first terminal device sends the first verification information to an in-vehicle device. When successfully verifying the first verification information, the in-vehicle device controls a vehicle to start.
