Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for maintaining vehicle ledgers are vulnerable to security threats, lack transparency, and are not secure or auditable, allowing unauthorized changes and hacking, which is critical for autonomous vehicles operating in complex environments.
Innovation Solution
Implementing a blockchain architecture to maintain and validate vehicle ledgers, ensuring that updates are secure, redundant, and immutable by using a distributed network with a master node that verifies and updates vehicle data stored in a blockchain, preventing unauthorized changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized ledger system is used to maintain vehicle data, then the system is easier to operate and manage, but it becomes vulnerable to security threats and unauthorized changes
Solution Approach 1:
The patent divides the centralized ledger into distributed blocks across multiple nodes in the network. Each block contains vehicle data and is segmented into immutable units that are distributed throughout the network, eliminating the single point of failure while maintaining operational simplicity through automated consensus mechanisms.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer between vehicle data and the ledger system. This intermediary provides cryptographic verification, consensus validation, and immutable recording, enhancing security without requiring complex manual intervention from operators.
2Productivity
If traditional ledger updating methods are used, then updates can be made quickly and easily, but the system lacks transparency and auditability
Solution Approach 1:
The patent implements a feedback mechanism where each ledger update is verified by multiple network nodes through consensus algorithms. The verification results are fed back to confirm the update's validity, providing transparent audit trails while maintaining efficient update processing through parallel verification.
Solution Approach 2:
The patent performs preliminary cryptographic hashing and validation of vehicle data before it is added to the blockchain. This preliminary action ensures data integrity and transparency are built into the structure from the beginning, allowing quick verification without slowing down the update process.
3Reliability
If a distributed blockchain network is implemented, then security and immutability are enhanced, but the system complexity increases
Solution Approach 1:
The patent implements a universal blockchain protocol that handles multiple functions including data validation, consensus reaching, immutable storage, and audit tracking within a single standardized framework. This multi-functionality reduces the need for separate complex systems while maintaining high security standards.
Solution Approach 2:
The patent adjusts key parameters such as block size, consensus threshold, and validation rules to optimize the balance between security and complexity. By carefully tuning these parameters, the system achieves robust security without excessive computational overhead or operational complexity.
4Adaptability or versatility
If unauthorized changes are allowed in the ledger, then the system is more flexible and adaptable, but it becomes vulnerable to hacking and malicious alterations
Solution Approach 1:
The patent applies preliminary anti-action by implementing cryptographic signatures and consensus validation before any ledger update is accepted. This pre-verification mechanism prevents malicious alterations while allowing legitimate adaptive changes, as the system can update its validation rules through the same secure process.

AI summary
Disclosed are systems and techniques for using blockchain technology to maintain and validate a vehicle ledger. The technique includes receiving, at a master node in the system, a request to update a vehicle ledger associated with a first vehicle node comprising the system. If first criteria are met, the system updates the vehicle ledger, including: generating an updated version of the vehicle ledger using vehicle data stored in a master ledger associated with the master node, and transmitting the updated version of the vehicle ledger to the first vehicle node. If the first criteria are not met, the system forgoes updating the vehicle ledger. The vehicle data corresponds to a first vehicle associated with the first vehicle node. The master ledger is implemented using a blockchain that contains vehicle records for vehicles associated with the system. The blockchain includes a first block including vehicle data corresponding to the first vehicle.
