Blockchain Digital Twin Management for IoT Asset Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital twin systems in IoT environments face challenges in creating, maintaining, and processing digital representations of physical assets, especially when these assets undergo changes and are decoupled from their physical counterparts, leading to difficulties in accurately tracking and updating their attributes and histories.
Innovation Solution
The implementation of a blockchain-based system for managing digital twins, which uses encryption technology to create a non-repudiable and verifiable electronic log of asset information, including changes in ownership, maintenance, and usage, ensuring the integrity and security of the digital record through a network of authorized agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital twin systems decouple digital representations from physical assets, then asset management flexibility is improved, but tracking accuracy and data integrity deteriorate
Solution Approach 1:
The patent introduces a blockchain-based intermediary ledger that mediates between physical assets and their digital twins. This intermediary maintains immutable records of asset attributes, ownership changes, and maintenance histories, ensuring tracking accuracy even when digital twins are decoupled from physical assets. The blockchain acts as a trusted mediator that preserves data integrity without requiring continuous physical-digital coupling.
2Device complexity
If traditional centralized systems manage digital twins, then system complexity is reduced, but security and data integrity deteriorate
Solution Approach 1:
The patent segments the digital twin management system into multiple independent components: physical asset identifiers, digital twin representations, blockchain-ledger records, and authorized agent networks. This segmentation distributes data integrity responsibilities across multiple nodes rather than relying on a single centralized authority, enhancing security while maintaining manageable system complexity through modular architecture.
3Reliability
If encrypted identifiers are used for digital twins, then security is improved, but lookup and retrieval operations deteriorate
Solution Approach 1:
The patent transforms encrypted identifiers into searchable forms through cryptographic hashing and indexing mechanisms. The system maintains encrypted identifiers for security while creating derived hash values that enable efficient lookup operations. This parameter transformation allows the system to simultaneously achieve high security through encryption and high lookup efficiency through cryptographic indexing, resolving the contradiction between security and operational ease.
Data Source
AI summary
Managing digital asset representation of physical assets in IoT systems and environments. A digital twin is created, tracked, and modified throughout the physical asset's lifetime using a digital registry having a data record including a unique identifier (optionally encrypted) and a storage device location information for the digital twin. A physical tag is coupled to the physical asset and scanned for read and write operations from and to the digital twin. The digital twin can move to a new storage device across a cloud environment and the registry maintains consistent access.
