Rental Vehicle Authentication With Optical Fallback Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating users for using reserved rental vehicles are prone to disruptions and failures due to unreliable communication technology connections, particularly in car-sharing scenarios where a secure and reliable authentication process is crucial.
Innovation Solution
A dual authentication system using radio-signal-based primary authentication information and optical image processing-based secondary authentication information, where the secondary authentication serves as a fallback in case of communication failures, ensuring reliable user verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If radio-signal-based primary authentication is used for user verification, then authentication speed and convenience are improved, but reliability deteriorates due to unstable communication connections
Solution Approach 1:
The patent implements a fallback authentication mechanism using optical image processing before communication failures occur. The system is designed with a secondary authentication path that activates when the primary radio-signal authentication fails, ensuring continuous operational reliability despite communication instability.
Solution Approach 2:
The patent changes the authentication parameter from radio-signal-based to optical-image-based when communication conditions are unfavorable. This parameter switching allows the system to adapt to different environmental conditions and maintain authentication reliability.
2Reliability
If dual authentication system with fallback mechanism is implemented, then authentication reliability is improved, but device complexity increases
Solution Approach 1:
The patent divides the authentication system into two independent modules: primary radio-signal authentication and secondary optical image authentication. Each module can operate independently, and the system selects the appropriate module based on communication availability, reducing the complexity burden of having both systems.
Solution Approach 2:
The authentication system is designed to perform multiple functions through a single unified architecture that can switch between radio-signal authentication and optical image authentication based on communication conditions, eliminating the need for entirely separate systems.

AI summary
The disclosure relates to a method for authenticating a user for using a reserved rental vehicle. In one embodiment, radio-signal-based primary authentication information is transmitted to an electronic input unit of the user and the user can be authenticated on the basis of a check of the primary authentication information using a server system outside the vehicle. Secondary authentication information based on optical image processing is transmitted, in addition to the primary authentication information, to the electronic input unit of the user and to an authentication unit of the rental vehicle. If the user could not be successfully authenticated for using the reserved rental vehicle using the primary authentication information, the user is authenticated for using the reserved rental vehicle on the basis of a check of the secondary authentication information using the authentication unit of the rental vehicle.
