Vehicle Payment Authentication via Mobile Digital Key
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle payment systems using simple payment services face security issues due to password exposure and misuse when the vehicle is stolen, as user authentication is typically performed within the vehicle, making it difficult to verify the registered user.
Innovation Solution
A system where user authentication is performed on a mobile device using a pre-registered car pay service, with the vehicle communicating with the mobile device to transmit authentication requests and control payments based on successful authentication, utilizing digital key services and various communication methods like Bluetooth, UWB, and NFC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user authentication is performed by inputting a password through a terminal provided inside the vehicle, then payment can be processed, but the password may be exposed to others and payment may be misused when the vehicle is stolen
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the user and the vehicle's payment system. The mobile device performs user authentication using biometric information or other secure methods, then communicates authentication results to the vehicle's processor. This intermediary approach prevents password exposure inside the vehicle while maintaining payment convenience, as the authentication occurs externally on the mobile device rather than through internal terminals.
2Reliability
If the vehicle communicates with a mobile device for authentication, then security is improved, but device complexity increases
Solution Approach 1:
The mobile device performs self-service authentication by utilizing its own built-in authentication capabilities (biometric sensors, secure elements) to verify user identity. The vehicle's processor simply receives authentication results from the mobile device rather than implementing its own complex authentication system. This self-service approach enhances security while minimizing the complexity increase on the vehicle side, as the mobile device handles the sophisticated authentication processes independently.

AI summary
A vehicle for performing a simple payment service, and a mobile device configured to perform communication with the vehicle includes a display, a communicator configured to perform communication with a mobile device, and a processor configured to transmit an authentication request signal to the mobile device when performing a car payment service, proceed with a payment when receiving authentication success information from the mobile device, and control the display to output authentication failure information and cancel the payment when the authentication failure information is received from the mobile device.
