Solution Overview

Problem

Current systems for storing and verifying data generated by vehicles lack a decentralized mechanism to authenticate and validate data, leading to potential tampering and lack of access for vehicle owners.

Innovation Solution

A decentralized consensus system for vehicular blockchain platforms is introduced, where a proposer vehicle generates transactions, obtains agreements on timestamp data from a quorum of validators, and generates digital signatures to validate transactions, thereby creating a secure and transparent record.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a centralized entity monopolizes vehicle data storage, then data management is simplified, but data authenticity cannot be verified by external entities and vehicle owners cannot access their data

Engineering Contradiction:
Improvedata managementVSAvoiddata authenticity verification
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent segments the centralized data storage system into a distributed network of nodes, where each node stores portions of the vehicle data ledger. This segmentation allows multiple entities (vehicle owners, manufacturers, third parties) to independently verify data authenticity while maintaining manageable data access through cryptographic segmentation of the ledger into blocks distributed across the network.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces cryptographic intermediaries (digital signatures, hash functions, and consensus protocols) that mediate between data producers and data verifiers. These cryptographic mechanisms enable trustless verification where vehicle owners can prove data authenticity without relying on centralized authorities, while manufacturers and third parties can verify claims without accessing raw sensor data.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If vehicle data is stored centrally, then data access control is simplified, but transparency and owner access are compromised

Engineering Contradiction:
Improvedata access controlVSAvoiddata transparency
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent enables vehicle owners to self-service their data by giving them cryptographic control keys that allow them to grant or revoke access permissions to their vehicle data without needing centralized authorization. Owners can independently manage who accesses their data (manufacturers, insurers, researchers) while maintaining transparency through the immutable ledger that records all access permissions and data transactions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent adds a cryptographic dimension to data access control, moving from simple centralized permission systems to a multi-dimensional access model where access rights are encoded in cryptographic tokens and verified through consensus protocols. This enables fine-grained control over data access while maintaining transparency through the distributed ledger that records all access events and permissions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If a decentralized consensus system is implemented, then data authenticity and transparency are improved, but system complexity increases

Engineering Contradiction:
Improvedata authenticityVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent changes the operational parameters of the system by implementing asynchronous consensus protocols and incremental ledger updates rather than requiring synchronous agreement from all nodes for every transaction. This allows the system to maintain high reliability through cryptographic verification while reducing operational complexity by allowing the network to process transactions in parallel and update the ledger incrementally rather than requiring complete system coordination.

Inventive Principle:
Principle #35Parameter changes

AI summary

A distributed ledger for vehicle transactions is provided. Also provided is a method of validating vehicle transactions, a method of obtaining a consensus on vehicle transactions, a method of entering data into a distributed ledger and a method of logging vehicle transactions. For each transaction of vehicle transactions, an agreement on a timestamp of the transaction is obtained to form a set of agreed transactions. For the ordered group of the agreed transactions, a consensus on a validity of the group of agreed transactions is obtained. The methods and systems of the present disclosure are specifically designed to address the consensus problem in the context of V2X but may also serve to reach consensus in other contexts. Furthermore, it enables reaching consensus with low latency and high throughput, and dynamic membership changes. It also requires limited (less) memory use to store consensus results. In embodiments, the ordering and commit are separated in achieving consensus (allowing parallel ordering which is quicker, thus lower ordering latency and higher throughput).
