Digital Key Sharing Flow for Vehicle Authorization Documents
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for proving authorization to operate a vehicle, such as carrying analog documents like registration and insurance certificates, are resource-intensive and time-consuming, limiting the ease of sharing vehicles and increasing user burden.
Innovation Solution
Utilizing the key sharing flow, typically defined in standards like the Car Connectivity Consortium (CCC) standard, to transmit additional information like vehicle registration and insurance certificates alongside the digital friend key, thereby integrating these documents into the existing key sharing infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If analog documents are used to prove authorization to operate a vehicle, then the authorization can be proven, but it is resource and time consuming to make documents available to each user
Solution Approach 1:
The patent creates digital copies of analog authorization documents (registration certificates, insurance certificates) and stores them in the backend system. These digital copies can be rapidly transmitted to multiple users without the resource and time constraints of physical document handling, resolving the contradiction between reliable authorization proof and quick document availability.
Solution Approach 2:
The backend system serves multiple functions: it stores authorization documents, manages digital key generation, and provides information to multiple users simultaneously. This multi-functional approach eliminates the need for separate physical document handling for each user, reducing time loss while maintaining authorization reliability.
2Productivity
If additional information is transmitted during key sharing flow, then information transfer efficiency is improved, but the key sharing flow complexity increases
Solution Approach 1:
The patent combines the transmission of digital keys and additional authorization information into a single key sharing flow process. By merging these transmissions, the system improves information transfer efficiency without requiring separate communication channels, and the standardized merging approach prevents excessive complexity increase.
Solution Approach 2:
The key sharing flow is enhanced to serve multiple purposes: transmitting the digital key itself and simultaneously transmitting additional authorization information. This multi-functional use of the existing key sharing infrastructure improves productivity while leveraging already-established protocols to minimize complexity increases.
