Cross-Chain Measurement Device State Management via Segmented Blockchains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing information about measurement devices lack sufficient security and efficiency, particularly in decentralized physical storage and blockchain-based systems, where information retrieval and management are hindered by inadequate security and increased physical configuration requirements for node devices.
Innovation Solution
A method and apparatus utilizing a network system with multiple blockchains, where data sender node devices and data manager node devices operate across different blockchains, employing smart contracts for management authority verification and cross-chain data management to securely store and manage device state information, reducing the need for extensive physical configuration on each node.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If all relevant parties upload information into the same blockchain, then information management efficiency is improved, but privacy and data security cannot be guaranteed
Solution Approach 1:
The patent divides the single blockchain system into multiple separate blockchains, with each relevant party having their own dedicated blockchain for storing sensitive information. This segmentation allows each party to maintain privacy and security while still enabling cross-chain information management through the Data Manager, thus resolving the contradiction between efficiency and security.
2Loss of time
If all relevant parties upload information into the same blockchain, then information retrieval efficiency is improved, but physical configuration requirements for node devices are increased
Solution Approach 1:
The patent extracts the heavy burden of storing all information from individual node devices by implementing a centralized Data Manager that handles cross-chain information retrieval. This allows node devices to have simpler physical configurations while maintaining efficient information retrieval through the Data Manager's coordination across multiple blockchains.
3Reliability
If decentralized physical storage is used, then security is improved, but information management and retrieval efficiency deteriorate
Solution Approach 1:
The patent introduces a Data Manager as an intermediary that coordinates information management across multiple decentralized blockchains. The Data Manager handles retrieval and management operations, allowing decentralized storage to maintain security while achieving efficient information management through the intermediary's coordination, thus resolving the contradiction between security and efficiency.

AI summary
A method and apparatus for managing information about a measurement device, which is applied to a network system including a plurality of blockchains that includes a first blockchain and a second blockchain, data sender node devices and data manager node devices, the method can comprise receiving a cross-chain request from a data manager node device for device state information associated with a measurement device stored in the first blockchain, wherein the data manager node device is a node device for a second blockchain, verifying, in response to the cross-chain request, that a data manager associated with the data manager node is authorized to manage the device state information, obtaining a target depository transaction corresponding to the device state information, wherein the target depository transaction is stored on the first blockchain and was previously saved to the first blockchain by a data sender node device, wherein the data sender node device is a node device for the first blockchain, and performing management of the device state information based on the target depository transaction.
