Vehicle Authentication via Digital Authenticator Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current taxi reservation systems lack effective safety measures for users, particularly children, the elderly, and intoxicated individuals, as they rely on visual verification of vehicle features, which is unreliable and does not ensure safety.
Innovation Solution
A vehicle authentication method where a terminal device verifies the authenticity of a reserved vehicle by comparing a vehicle authenticator with one received from the vehicle, displaying a message indicating whether the vehicle is reserved or not, thereby enhancing security and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visual verification of vehicle features is used for authentication, then the system is simple and easy to operate, but the security level and reliability are insufficient
Solution Approach 1:
The patent replaces the mechanical/visual verification method with an electronic authentication system. The terminal device communicates with the vehicle's on-board device to exchange authentication information (QR code or character string), eliminating the need for manual visual checking of vehicle features. This substitution of mechanical verification with electronic data exchange resolves the contradiction by providing reliable automated authentication without requiring complex additional hardware.
Solution Approach 2:
The patent uses QR codes or character strings as digital copies of authentication information. Instead of verifying physical vehicle features, the system creates and verifies digital representations (QR codes displayed on terminal device or vehicle display, character strings) that encode the same authentication data. This copying approach maintains simplicity while significantly improving reliability through automated digital verification.
2Reliability
If automated authentication is implemented, then security level is improved, but ease of operation may deteriorate
Solution Approach 1:
The authentication system operates autonomously without requiring user intervention. The terminal device automatically exchanges authentication information with the vehicle's on-board device, and the system automatically verifies the data and provides authentication results. This self-service mechanism resolves the contradiction by eliminating manual verification steps, making the process as convenient as showing a QR code while maintaining high security through automated cryptographic verification.
Solution Approach 2:
The system provides immediate feedback to the user through the terminal device, clearly indicating whether authentication succeeded or failed. This feedback mechanism simplifies operation by eliminating ambiguity - users simply need to present their reservation information and receive an instant yes/no answer, making the process intuitive and easy to operate while maintaining strict security verification.
3Object-affected harmful factors
If manual verification by users is required, then the system complexity is low, but safety for vulnerable users (children, elderly, intoxicated persons) cannot be ensured
Solution Approach 1:
The patent replaces manual user verification with automated electronic authentication. The terminal device automatically exchanges and verifies authentication information with the vehicle system, eliminating the need for users to perform judgment or verification actions. This substitution resolves the contradiction by providing complete automation that ensures safety for all users regardless of their physical or mental state, while the system complexity remains manageable through use of standard communication protocols.

AI summary
A vehicle authentication method, a recording medium storing a program, a terminal device, and a vehicle authentication system which may raise security level on vehicle authentication by a user are provided. In the vehicle authentication method, the terminal device acquires a vehicle authenticator for authentication of a reserved vehicle, sends a reference vehicle a request for a vehicle authenticator for authentication of the reference vehicle, and determines whether the vehicle authenticators of the reference vehicle and the reserved vehicle coincide. Then a message that the reference vehicle is the reserved vehicle is displayed on the display unit upon determination that the vehicle authenticators of the reference vehicle and the reserved vehicle coincide. And a message that the reference vehicle is not the reserved vehicle is displayed on the display unit upon determination that the vehicle authenticators of the reference vehicle and the reserved vehicle do not coincide.
