IoT Terminal Blockchain Data Integrity Falsification Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing management systems for IoT devices lack reliability in preventing falsification of logs and settings during operation, particularly in distributed storage and data collection from multiple locations, leading to increased management costs and risks of operational stoppages and data loss.
Innovation Solution
A terminal device connected to a network retains a blockchain formed by linking data generated by each terminal device or its hash values, allowing new data to be added when a new device joins, and includes mechanisms for detecting falsification by comparing retention data with data stored on the blockchain, disconnecting from unauthorized connections, and invalidating falsified data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored at multiple third parties to prevent falsification, then data reliability is improved, but the system becomes unsuitable for collecting data from scattered IoT devices in multiple locations
Solution Approach 1:
The patent divides the centralized storage system into distributed storage across multiple third parties, where each third party stores data from specific terminal devices. This segmentation allows the system to maintain data reliability through distribution while adapting to IoT scenarios by enabling flexible data collection from scattered devices through multiple access points without requiring a single centralized storage location
Solution Approach 2:
The patent creates a universal storage architecture where multiple third parties can store and manage data from various terminal devices simultaneously. This multi-functional storage system can handle both traditional centralized data management and distributed IoT data collection, allowing the same infrastructure to serve multiple purposes including data reliability, device authentication, and flexible data retrieval from any location
2Reliability
If operational logs and setting value data are stored for each tenant and customer, then data management is improved, but management costs and risk of operational stoppage increase
Solution Approach 1:
The patent merges the storage responsibilities for multiple tenants and customers into a unified distributed storage system managed by third parties. Instead of maintaining separate storage infrastructures for each tenant, the system combines them into a shared storage architecture where data is organized by terminal device identifiers, reducing overall system complexity while maintaining the ability to manage data for multiple customers simultaneously
Solution Approach 2:
The patent introduces third parties as intermediary storage providers between the terminal devices and the data management system. These third parties act as mediators that handle the actual data storage operations, allowing the management system to focus on higher-level functions like data retrieval and processing without being burdened by the complexity of maintaining separate storage infrastructures for each tenant
3Ease of operation
If centralized storage is used for operational logs, then data collection is simplified, but the risk of data loss increases in case of service provider failure
Solution Approach 1:
The patent segments the centralized storage into distributed storage across multiple third parties, where data from terminal devices is stored at different locations. This segmentation maintains ease of operation through a unified data retrieval interface while eliminating single-point-of-failure risks by distributing data across multiple independent storage entities that can continue operating even if one third party fails

AI summary
There are provided a terminal device, a data management device, a management system, a processing method, a data management method, a management method, and a non-transitory computer-readable medium storing a program that are capable of improving reliability. A terminal device is connected to a network together with other terminal devices, retains a blockchain formed by linking data generated by the respective terminal devices or a hash value of the data as blocks together with the other terminal devices, and adds, when a new terminal device is to be added to the network, new data generated by the new terminal device or a hash value of the new data to the blockchain together with the other terminal devices.
