Vehicle Digital Key Authentication With Biometric Driver Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems lack effective methods for authenticating drivers using digital keys, leading to potential security and safety risks, especially in autonomous driving scenarios.
Innovation Solution
Implementing a system where driver identification information is matched with a digital key stored in an electronic device, allowing only authenticated drivers to control the vehicle, and integrating biometric authentication to enhance personal identification and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver authentication using digital key matching is implemented, then vehicle security and safety are improved, but device complexity increases
Solution Approach 1:
The patent uses digital keys as virtual copies of physical vehicle keys, storing authentication data in electronic form within mobile devices. This copying approach enables secure authentication without requiring physical key exchange, thereby improving vehicle security while managing system complexity through digitalization
Solution Approach 2:
The patent introduces a server as an intermediary that facilitates the matching process between driver identification information and digital keys. The server mediates the authentication by receiving requests from terminal devices, performing the matching operation, and returning authentication results, thus simplifying the overall system architecture while maintaining high security standards
2Measurement precision
If biometric authentication is integrated with digital key matching, then personal identification accuracy is improved, but measurement precision requirements increase
Solution Approach 1:
The patent merges biometric authentication with digital key matching into a unified authentication system. The terminal device captures biometric data (such as facial recognition or fingerprint), extracts identification information, and combines it with digital key verification. This merging approach enhances personal identification accuracy by using multiple authentication factors while managing measurement precision requirements through integrated processing
3Reliability
If driver authentication is enforced for all vehicle control functions, then safety is improved, but ease of operation decreases
Solution Approach 1:
The patent implements preliminary authentication where driver identity is verified in advance before vehicle control functions are activated. The terminal device performs digital key matching and biometric verification beforehand, and once authenticated, the driver can operate vehicle functions without repeated authentication. This preliminary action ensures safety while maintaining ease of operation during actual driving
