Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connected vehicles face security challenges due to increased susceptibility to data breaches and credibility issues when sharing data with other devices, affecting safety and security, especially in real-time communication scenarios.
Innovation Solution
Implementing a blockchain network that allows connected vehicles to share vehicular data securely and autonomously, with users having control over data sharing policies through smart contracts, enabling selective data sharing with other entities within a defined geographic scope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connected vehicles share data with other devices and networks, then the functionality and connectivity of the vehicle is improved, but the security and susceptibility to data breaches worsens
Solution Approach 1:
The patent introduces a blockchain network as an intermediary layer between connected vehicles and external networks. This mediator enables data sharing while implementing decentralized security protocols, smart contracts for access control, and cryptographic verification mechanisms that prevent direct exposure to security threats.
Solution Approach 2:
The patent segments the data sharing architecture into multiple layers: vehicle-level data collection, blockchain-level verification and storage, and application-level data utilization. This segmentation isolates security vulnerabilities to specific layers while maintaining overall system connectivity and data sharing functionality.
2Reliability
If users have control over data sharing policies, then the privacy and security is improved, but the complexity of data management increases
Solution Approach 1:
The patent implements self-service mechanisms through automated smart contracts that execute data sharing policies without manual intervention. Users define their preferences once, and the system automatically manages data sharing decisions, reducing ongoing management complexity while maintaining user control.
Solution Approach 2:
The patent incorporates feedback loops where the system monitors data sharing activities, verifies policy compliance through blockchain validation, and provides users with visibility into data usage. This automated feedback reduces the cognitive burden on users while ensuring their preferences are respected.
3Reliability
If blockchain network is implemented for secure data sharing, then the security and verifiability is improved, but the system complexity increases
Solution Approach 1:
The patent designs the blockchain network to serve multiple functions simultaneously: decentralized data verification, secure storage, smart contract execution for policy enforcement, and cryptographic identity management. This multi-functionality consolidates what would otherwise require separate systems into a single integrated platform.
Solution Approach 2:
The patent merges traditional data sharing infrastructure with blockchain technology, combining centralized data collection capabilities with decentralized verification. This hybrid approach leverages the strengths of both architectures while mitigating their individual weaknesses, reducing overall system complexity.

AI summary
Examples described herein relate to a system including a BC network associated with a plurality of entities in a defined geographic scope. A first entity of the plurality of entities includes a connected vehicle that generates vehicular data. The BC network is governed by a smart contract. The smart contract includes a data sharing policy defined by a user of the connected vehicle, wherein the data sharing policy allows the user of the connected vehicle to selectively share the vehicular data with one or more other entities of the plurality of entities.
