Vehicle Service Authorization Through Context-Based Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in determining whether there is authorization for specific automotive services on a vehicle, as impersonation or unauthorized repair facilities can perform services without proper verification, leading to issues with warranty claims and increased costs.
Innovation Solution
A context-based authentication system using a vehicle controller, server system, and second factor authentication to verify the authorization of automotive services by checking location, timing, and identity, ensuring that only authorized entities can access vehicle components for repairs or updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If verbal agreement or signature on physical document is used for authorization, then the authorization process is simple and quick, but there is risk of impersonation and unauthorized repair facilities performing services
Solution Approach 1:
The patent introduces a server system as an intermediary between the vehicle operator and repair facility. The server receives authorization requests from the repair facility, verifies them against authorization data stored there, and provides verification responses. This intermediary layer maintains the simplicity of the authorization process while adding reliable verification to prevent impersonation and unauthorized services.
2Device complexity
If traditional authorization methods are used, then the system complexity is low, but fraud detection and authorization verification are difficult
Solution Approach 1:
The patent implements a feedback mechanism where the server system provides verification responses to repair facilities based on authorization data. The system continuously monitors authorization requests, compares them against stored authorization information, and provides real-time feedback on whether authorization is valid. This feedback loop enables effective fraud detection without significantly increasing system complexity.
3Ease of operation
If manual verification of authorization is performed, then the process is straightforward, but it increases time consumption and reduces productivity
Solution Approach 1:
The patent replaces manual verification processes with automated electronic communication between the repair facility, server system, and vehicle controller. Instead of manual checking of physical documents or verbal agreements, the system uses electronic authorization requests and verification responses transmitted through the server, significantly reducing verification time while maintaining simplicity.
