Vehicle Door Access Control With Biometric Mobile-Vehicle Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door access control systems, such as electric doors and gates, are vulnerable to unauthorized access when the remote control is lost or stolen, lacking robust security measures for verification and authorization.
Innovation Solution
A method involving pairing a smart mobile device with an external door access device, registering vehicle key information, and using biometric verification through a vehicle end biological feature pick-up device to authorize unlocking, ensuring correct vehicle key and device pairing before allowing access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control is used to control the electric door or electric gate, then the operation is simple and convenient, but the security is poor because the user cannot open the door when the remote control is lost and anyone with the remote can open it
Solution Approach 1:
The access control system is segmented into multiple independent verification components: vehicle identification verification, smart mobile device pairing verification, and biological feature verification. Each component operates independently but must all succeed for access to be granted, thereby maintaining operational convenience while significantly enhancing security against lost or stolen credentials
Solution Approach 2:
The system performs preliminary verification actions before granting access: first verifying the vehicle key information, then verifying the smart mobile device pairing status, and finally performing biological feature verification. These preliminary checks ensure that only authorized users with proper credentials and biometric matching can operate the door, preventing unauthorized access while maintaining a smooth user experience
2Reliability
If multiple verification steps are added to improve security, then the access security is enhanced, but the operation complexity increases
Solution Approach 1:
Multiple verification functions (vehicle identification, smart device pairing, biological feature recognition) are merged into a single integrated access control system. The control unit coordinates all verification steps and consolidates the results, allowing the system to maintain high security through multiple checks while presenting a unified, simple interface to the user, thereby reducing perceived complexity
Solution Approach 2:
The control unit acts as an intermediary that manages the complex verification process. It receives inputs from various sensors (vehicle key detector, smart device communicator, biological feature sensor), processes the verification logic, and controls the door actuator. This intermediary layer shields the user from the underlying system complexity while ensuring rigorous security verification
3Reliability
If biometric verification is implemented, then the unauthorized access is prevented, but the device complexity and verification time increase
Solution Approach 1:
The system performs preliminary verification of vehicle key information and smart mobile device pairing status before initiating biometric verification. This preliminary action ensures that only pre-authorized vehicles and devices proceed to the time-consuming biometric check, reducing unnecessary verification time while maintaining high authorization accuracy for legitimate users
Solution Approach 2:
The system replaces traditional mechanical or manual verification methods with automated electronic and optical systems: RFID or Bluetooth for vehicle key detection, wireless communication for smart device pairing, and optical/spectral sensors for biometric recognition. This substitution significantly reduces verification time while improving authorization accuracy compared to manual checking methods

AI summary
A vehicle door access control method comprises using a smart mobile device to obtain management authority of an external door access device. Then, the smart mobile device is used to authorize the unlocking authority to a vehicle host, such that the external door access device permits use of the smart mobile device or the vehicle to proceed with unlocking or opening operation.
