Cross-Protocol Vehicle Key Mapping for Secure Data Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital vehicle key systems face challenges in managing vehicle key data across different protocols, leading to difficulties in identifying and displaying vehicle keys belonging to the same vehicle, which compromises user experience and data security.
Innovation Solution
A method and apparatus for processing vehicle data that involves obtaining and transmitting vehicle identifiers defined under different protocols to a server, establishing relations between these identifiers, and determining which identifiers correspond to the same vehicle, thereby enabling accurate and secure management of vehicle key data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple vehicle key protocols are supported to improve compatibility, then the device can work with more vehicle models, but the complexity of managing vehicle key data increases
Solution Approach 1:
The patent introduces a server as an intermediary component that centralizes the management of vehicle key data across multiple protocols. The server receives vehicle identifiers from different protocols, processes them, and returns mapping relationships. This mediator approach allows the client device to support multiple protocols without directly managing the complexity of cross-protocol data relationships, effectively resolving the contradiction between versatility and complexity.
2Reliability
If vehicle identifiers from different protocols are managed separately, then protocol independence is maintained, but the ability to identify and display keys belonging to the same vehicle is compromised
Solution Approach 1:
The patent merges vehicle identifier data from different protocols at the server level while maintaining protocol independence. The server collects vehicle identifiers from various protocols, processes them together to establish mapping relationships, and returns the combined information. This merging approach preserves the original protocol structures while recovering the lost association information through centralized processing.
Solution Approach 2:
The system implements a feedback mechanism where the server processes vehicle identifiers from multiple protocols and returns mapping relationships to the client. This feedback loop enables the client to identify and display keys belonging to the same vehicle by receiving processed information that links identifiers across protocols, thus recovering the association information that would otherwise be lost.
3Ease of operation
If vehicle identification numbers are shared across protocols to improve key management, then vehicle key association is improved, but data security is compromised
Solution Approach 1:
The patent segments the vehicle key management system into client and server components with distinct responsibilities. The client collects vehicle identifiers from different protocols without exposing the actual vehicle identification numbers. The server performs the secure processing and mapping operations. This segmentation allows convenient key management through centralized processing while maintaining data security by preventing direct exposure of sensitive vehicle identification numbers.
Data Source
AI summary
A method for processing vehicle data, includes: obtaining a plurality of identifiers, where the plurality of identifiers include vehicle identifiers defined under different vehicle key protocols; transmitting the plurality of identifiers to a server of the vehicle; and receiving a processing result processed and transmitted by the server, where the processing result includes one or more relations between the plurality of identifiers. The plurality of identifiers having the relation are the identifiers, defined under different vehicle key protocols, of a same vehicle.
