Cross-linked Distributed Ledger for Vehicle Data Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current networked databases used by rental and ride-sharing companies lack permanent records and accurate data sharing across systems, leading to inaccuracies and isolation of information between different databases.
Innovation Solution
A cross-linked distributed ledger system that connects multiple computing devices to maintain linked records across different ledgers, allowing for shared attributes to link records between them, ensuring immutable and authenticated records.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional networked databases are used to store vehicle and driver information, then data can be easily modified and updated, but permanent records are not maintained and data accuracy cannot be ensured
Solution Approach 1:
The patent replaces traditional centralized database systems with a blockchain-based distributed ledger system. This substitution introduces cryptographic hashing, distributed consensus mechanisms, and immutable block chaining to replace conventional database update and verification processes, thereby ensuring permanent and accurate records while maintaining manageable system complexity through standardized protocols
Solution Approach 2:
The patent introduces a distributed ledger as an intermediary layer between different companies' data systems. This intermediary maintains immutable records of vehicle and driver information, allowing multiple parties to access and verify data without directly modifying each other's databases, thus ensuring data accuracy while simplifying inter-company data sharing
2Loss of information
If separate distributed ledgers are used by different companies, then data security and autonomy are maintained, but information cannot be shared between ledgers
Solution Approach 1:
The patent merges multiple separate distributed ledgers into a unified cross-linked distributed ledger system. Different companies' ledgers are connected through cryptographic cross-referencing and shared consensus mechanisms, allowing information to flow between previously isolated systems while maintaining the security and autonomy of each participant through distributed consensus protocols
Solution Approach 2:
The patent creates a universal distributed ledger framework that can accommodate multiple companies and data types within a single system. The cross-linked structure allows the same ledger infrastructure to serve different organizations while maintaining their data sovereignty, enabling information sharing without requiring separate integration systems for each company pair
3Stability of the object's composition
If centralized databases are used for data storage, then data modification is easy, but data cannot be permanently recorded and is susceptible to inaccuracies
Solution Approach 1:
The patent applies preliminary action by requiring data verification and consensus approval before records are written to the blockchain. This pre-confirmation process ensures data accuracy before immutability is enforced, allowing easy updates through the standardized consensus process while maintaining permanent records once confirmed
Solution Approach 2:
The patent introduces dynamics by allowing the system to transition between different states: data can be easily modified during the consensus process, then becomes immutable once confirmed. The system dynamically adjusts between flexibility for updates and rigidity for permanent recording based on the consensus state, resolving the contradiction between ease of update and record stability
