Information Management Node with Temporary Storage and History Flag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In distributed processing networks, collecting and restoring data from multiple nodes is costly in terms of time, CPU power, and network traffic, and can be inefficient due to the need for each node to manage and share large amounts of data.
Innovation Solution
An information management method and device that allows nodes to collect and restore divided data, store it temporarily with a history flag, and manage access and modification, enabling efficient data usage and reduction of data burden by discarding data based on flag conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data are distributed to and shared with arbitrary nodes in a P2P network, then the flexibility and convenience of the network system are improved, but the burden of processing and managing distributed data increases
Solution Approach 1:
The patent introduces a central server as an intermediary that manages distributed data files. The server stores file information including division information, storage location information, and restoration information. When data needs to be restored, the server coordinates the collection of divided data from multiple nodes and manages the restoration process, thereby reducing the processing burden on individual nodes while maintaining the flexibility of the distributed P2P network architecture.
2Ease of operation
If data are collected and restored from a large network, then the user can acquire distributed data, but it requires great cost in terms of time, CPU power, and network traffic
Solution Approach 1:
The patent implements preliminary action by pre-storing file information on the central server, including division information that identifies how data is segmented, storage location information that maps divided data to specific nodes, and restoration information that guides the restoration process. This pre-organized information allows nodes to quickly locate and retrieve the necessary divided data segments without performing exhaustive searches, significantly reducing the time and computational resources required for data restoration.
3Quantity of substance
If each node manages and shares large amounts of distributed data, then the network can store more data, but the efficiency decreases due to the need for each node to collect and restore data
Solution Approach 1:
The patent applies segmentation by dividing large data files into multiple smaller divided data segments and distributing them across different nodes in the network. The central server maintains metadata that tracks which segments are stored at which nodes. This segmentation allows the network to store large amounts of data across multiple nodes while improving efficiency, as nodes only need to handle and transfer specific segments rather than managing entire large files, and the server coordinates restoration by collecting only the necessary segments.
Data Source
AI summary
An information management method and an information processing device functioning as a node are provided to enable an effective use of information distributed to, and shared with, a plurality of nodes on a network and to enable maintenance of security against leakage of information by controlling information retention. This management method of information gathers information distributed to, and shared with, a plurality of the nodes on a network and holds the information in a state accessible from other nodes to a temporary information memory unit when generating restored information. The information management method is also characterized in setting a flag for showing a history of the information and immediately discarding the information in the case that the retention of restored information becomes improper from a view point of contents of the flag.
