Motor Vehicle Digital Copy Blockchain Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating digital copies of motor vehicles allow for easy replication, making it difficult to ensure that only the vehicle's owner has access to the digital copy and maintain authenticity in vehicle collections.
Innovation Solution
A method involving generating a private key stored in the vehicle's data memory and using it to store the digital copy in a blockchain, preventing replication and ensuring access is restricted to the vehicle's owner, with the blockchain's decentralized and immutable nature verifying authenticity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a digital copy of a motor vehicle is created using conventional methods, then the digital copy can be viewed and accessed, but the digital copy can be easily replicated and distributed to multiple users
Solution Approach 1:
A blockchain system serves as an intermediary between the digital copy and users. The blockchain stores the digital copy in a decentralized manner with cryptographic verification, allowing authorized access while preventing unauthorized replication. The private key stored in the vehicle's data memory acts as a mediator that enables authentication without exposing the actual digital copy content.
Solution Approach 2:
The patent creates a cryptographic copy (hash) of the digital copy that is stored on the blockchain, rather than storing the actual digital copy itself. This cryptographic representation can be verified without revealing the original content, allowing authentication and verification while preventing direct replication of the actual digital copy.
2Reliability
If the digital copy is stored in a centralized location, then access control can be managed, but the system is vulnerable to manipulation and unauthorized access
Solution Approach 1:
The system segments the digital copy into a cryptographic hash that is stored on the blockchain and the actual content that remains protected in the vehicle's data memory. This segmentation allows the integrity verification function to be distributed to the blockchain while keeping the actual content secure and private.
Solution Approach 2:
The patent transforms the digital copy into a different parameter form (cryptographic hash) that can be stored and verified on the blockchain without exposing the original content. This parameter transformation maintains the ability to verify integrity while preventing unauthorized access to the actual digital copy.
3Reliability
If a private key is generated and stored in the vehicle's data memory, then access to the digital copy can be restricted, but the system becomes more complex
Solution Approach 1:
The vehicle's data memory system performs self-service by generating and storing its own private key for cryptographic authentication. This eliminates the need for external key management infrastructure, allowing the vehicle to autonomously manage its own access credentials while integrating with the blockchain network.
