Solution Overview
Problem
Conventional data distributed storage methods do not account for changes in the arrangement and configuration of devices serving as data storage destinations, making them inadequate for dynamically adapting to network changes and security threats in IoT environments.
Innovation Solution
A cooperative distributed storage system that includes information processing devices capable of dividing data into multiple pieces, acquiring state information to determine dynamic storage destinations, and using a storage controller to distribute and store data across multiple devices, ensuring secure storage even if individual devices are compromised.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is distributed and stored in multiple devices, then security against physical robbery is improved, but the system cannot adapt to changes in device arrangement and configuration
Solution Approach 1:
The patent implements dynamic destination determination that automatically adapts to changes in device arrangement and configuration. The system continuously monitors the state of storage destinations and dynamically selects new destinations when devices are added, removed, or relocated, thereby maintaining both security through distribution and adaptability to environmental changes.
Solution Approach 2:
The system employs feedback mechanisms where the information processing device acquires state information about storage destinations and uses this feedback to dynamically adjust data distribution. When changes in device configuration are detected, the system responds by recalculating and redistributing data to appropriate destinations, ensuring continuous adaptability while maintaining security.
2Reliability
If conventional data distributed storage methods are used, then data can be stored in multiple devices, but the methods do not account for dynamic changes in network environment
Solution Approach 1:
The patent transforms the static conventional storage method into a dynamic system that continuously monitors network environment changes. The information processing device dynamically determines storage destinations based on real-time state information, allowing the system to adapt to network changes while maintaining the security benefits of distributed storage.
Solution Approach 2:
The system performs self-service by automatically detecting changes in the network environment and autonomously redistributing data without requiring manual intervention. The information processing device independently acquires state information, determines appropriate destinations, and executes data redistribution, enabling the system to adapt to network changes while maintaining security.
3Reliability
If data is divided and stored in multiple devices, then information leakage is prevented, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing data into multiple pieces and distributing them across different storage destinations. This segmentation approach prevents information leakage since no single device contains the complete data, thereby improving security. The system manages this complexity through automated destination determination rather than manual configuration.
Solution Approach 2:
The system reduces operational complexity by implementing self-service automation. The information processing device automatically divides data, determines appropriate storage destinations based on state information, and distributes data segments without requiring manual intervention. This automation maintains high security through segmentation while reducing the complexity burden on users.
