Blockchain Traffic Data Verification via Distributed Vehicle Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current traffic information processing systems face challenges in accuracy and security due to time delays in real-time updates, lack of protection for vehicle position information, and the risk of hacking and server overload as vehicles report position data to central servers.
Innovation Solution
Implementing a blockchain-based system where vehicles collect and verify traffic information, updating blocks with this data and sharing them across a network for validation, ensuring secure and immediate verification and sharing of traffic information through a decentralized network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles report position information to a central server, then traffic information can be collected and processed, but the system becomes vulnerable to hacking and server overload
Solution Approach 1:
The patent divides the centralized server system into distributed vehicle nodes that each maintain blockchain copies. Instead of one central server handling all traffic information, the system segments functionality across multiple vehicles, with each vehicle capable of verifying and storing traffic data independently through its local blockchain implementation.
Solution Approach 2:
The blockchain technology acts as an intermediary layer between vehicles and the traffic information system. Rather than direct server-vehicle communication that creates single points of failure, the blockchain ledger mediates information exchange, providing cryptographic verification and distributed consensus that prevents hacking and overload on any single node.
2Productivity
If vehicles periodically report position data to a server, then real-time traffic information can be generated, but time delays occur in updates
Solution Approach 1:
Vehicles autonomously verify and validate traffic information using blockchain consensus mechanisms without waiting for centralized server processing. Each vehicle independently checks the validity of position data and traffic information against the blockchain ledger, enabling immediate local decision-making and eliminating server processing delays.
Solution Approach 2:
The system pre-establishes blockchain ledgers and verification protocols in each vehicle before traffic information exchange begins. This preliminary configuration allows vehicles to immediately validate and process position data upon receipt without requiring real-time server authorization, reducing update latency.
3Ease of operation
If a central server processes all traffic information, then information can be centralized for easy management, but the system lacks protection for vehicle position information
Solution Approach 1:
Each vehicle maintains its own local blockchain ledger with encrypted position information specific to its context. Rather than centralizing all data in one server, the system allows each node to manage its relevant traffic information locally with cryptographic protection, providing both ease of local management and enhanced security through distributed storage.
Solution Approach 2:
The blockchain technology creates cryptographic copies of traffic information across multiple vehicles instead of storing all data in a single central server. Each vehicle holds a verified copy of the blockchain ledger containing position information, eliminating the single point of failure while maintaining data accessibility and management capabilities.
4Reliability
If multiple vehicles share traffic information through a decentralized network, then security and accuracy are enhanced, but system complexity increases
Solution Approach 1:
The blockchain protocol implements universal verification rules that work across all vehicles in the network. Each vehicle runs the same consensus algorithm and validation logic, allowing complex decentralized verification to be achieved through standardized, multi-functional code that handles position data validation, timestamp verification, and consensus reaching in a unified manner.
Data Source
AI summary
A system and method of processing traffic information using blockchain technology is disclosed. The method includes collecting traffic information by a first vehicle, updating a first block using the collected traffic information by the first vehicle, sharing a verification target block corresponding to the updated first block in a network by the first vehicle, verifying the shared verification target block by at least one second vehicle present in the network, and sharing a second block including the updated traffic information in the network when the verifying is successful by the at least one second vehicle.
