Ring NFC Vehicle Authentication for Shared Multi-Vehicle Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle authentication systems, particularly in shared or rental vehicles, face challenges in convenience and security when using mobile phones as electronic keys, as users need to manually operate them for verification, and there is a need to support multiple vehicle access without device changes.
Innovation Solution
A vehicle authentication system incorporating a ring-type wearable device with NFC capabilities for short-range communication and an in-vehicle device with a wide area communication module, allowing secure and convenient authentication by transmitting unique identification information via NFC and network communication, enabling use of multiple vehicles with a single device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile phone is used as an electronic key for vehicle authentication, then users can access the vehicle wirelessly, but users need to manually operate the mobile phone for verification which reduces convenience
Solution Approach 1:
The ring-type wearable device automatically transmits identification information to the in-vehicle device through NFC communication when in proximity, enabling the authentication process to occur without any manual operation by the user. The device serves itself by autonomously completing the verification process that previously required user intervention with a mobile phone.
Solution Approach 2:
The manual operation of pressing buttons or initiating authentication on a mobile phone is replaced by contactless NFC communication. The mechanical interaction (button pressing) is substituted with automatic wireless data transmission through the ring device, eliminating the need for user manipulation while maintaining secure authentication.
2Adaptability or versatility
If a single electronic key device is used to access multiple vehicles, then device portability is improved, but authentication security may be compromised
Solution Approach 1:
The authentication system is segmented into multiple independent verification layers: the ring device provides unique identification information, the in-vehicle device verifies this information against reservation data, and the NFC communication protocol adds cryptographic security. This segmentation allows a single ring device to securely access multiple vehicles by validating each authentication request independently.
Solution Approach 2:
The NFC communication protocol acts as an intermediary that securely transmits and verifies identification information between the ring device and in-vehicle device. This intermediary layer ensures that even though a single device accesses multiple vehicles, each transaction is securely mediated through standardized verification protocols, preventing unauthorized access.
3Reliability
If short-range NFC communication is used for authentication, then security is enhanced through proximity verification, but communication range is limited
Solution Approach 1:
The system uses partial action by limiting NFC communication to only the final authentication phase when the user is already in proximity to the vehicle. The short communication range is sufficient for this specific purpose, and the system does not attempt to extend range unnecessarily, maintaining security while completing the authentication function.
Solution Approach 2:
Reservation information and vehicle identification data are preliminarily exchanged through wide area network communication before the user approaches the vehicle. This preliminary action allows the NFC communication to focus solely on verifying pre-established credentials, making the short communication range adequate for the security-critical authentication step.

AI summary
A vehicle authentication system includes a ring-type wearable device, an in-vehicle device, and a communication terminal. The in-vehicle device performs authentication regarding use of the vehicle. The in-vehicle device causes a short-range communication module to perform short-range wireless communication with the ring-type wearable device that has unique identification information. The in-vehicle device acquires information received by a wide area communication module configured to communicate, via a network, with the communication terminal configured to make a reservation for the use of the vehicle.
