Biometric Authentication for Shared Vehicle Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Car-sharing services face issues with unauthorized use due to the potential misuse of key cards and PINs, as well as the inability to verify if a user still holds a valid driver's license, leading to unregulated access to shared vehicles.
Innovation Solution
Implementing a biometric data verification system that compares user-provided biometric data with stored data, using a remote screening facility for authentication, and automatically setting ergonomic and comfort components based on authorized user profiles, ensuring only authorized users can operate shared vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric verification systems are implemented, then security against unauthorized use is improved, but device complexity increases
Solution Approach 1:
The patent introduces a biometric verification system as an intermediary between the user and the vehicle access system. This intermediary layer captures biometric data (fingerprint, facial recognition, or iris scan) and verifies it against stored data before granting access, thereby enhancing security without requiring fundamental changes to the vehicle's core systems.
Solution Approach 2:
The patent replaces traditional mechanical access methods (physical keys, key cards, PIN codes) with biometric authentication systems. This substitution eliminates the need for users to carry physical access devices and prevents unauthorized use through biometric data theft, as biometric traits cannot be easily replicated or lost like physical keys.
2Reliability
If multiple authentication methods are used, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements a dynamic authentication system that adapts the verification process based on the situation. The system can switch between different biometric methods (fingerprint, facial recognition, iris scan) and adjust the level of verification required, making the authentication process both secure and convenient depending on the context.
Solution Approach 2:
The system performs preliminary biometric verification before granting full access to the vehicle. By capturing and verifying biometric data in advance during the authentication process, the system ensures security is maintained while the actual vehicle operation remains simple and user-friendly.
3Reliability
If continuous biometric monitoring is implemented, then unauthorized use detection is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic biometric monitoring rather than continuous monitoring. The system captures biometric data at regular intervals during vehicle operation to verify that the authorized user remains in control, thereby detecting unauthorized use while minimizing energy consumption by keeping the monitoring system dormant between measurement cycles.

AI summary
A shared vehicle authenticates a holder of a driver's license prior to the holder accessing and operating the shared vehicle. Previously captured biometric data of at least one biometric feature of the holder of the driving license is obtained from the driver's license. Newly captured biometric data of a corresponding biometric feature of the holder is detected when the holder wants to operate the shared vehicle. The previously captured biometric data and the newly captured biometric data are compared to verify the holder is authorized to operate the shared vehicle. When the biometric data match, the shared vehicle is released for use by the holder. In some instances, biometric data of the driver of the shared vehicle is captured at select times while the shared vehicle is operated to confirm the driver is the holder of the driver's license.
