Relay Apparatus User Data Deletion Across Storage Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current relay apparatus systems lack an efficient method for managing user access rights and deleting user data across multiple storage areas, particularly when users transition between different service areas, leading to inconsistencies and inefficiencies in data management.
Innovation Solution
A relay apparatus with a memory for user management tables, a receiving unit for processing deletion requests, a changing unit for updating state information, and a process executing unit for deleting data from both local and remote storage areas at predetermined times, ensuring synchronized data removal across the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user data is stored in multiple relay apparatus storage areas to enable access across service areas, then user accessibility is improved, but data consistency and deletion synchronization deteriorate
Solution Approach 1:
The system implements a feedback mechanism where the first relay apparatus monitors the storage status of user data in the second relay apparatus. When deletion is requested, the first relay apparatus sends a deletion notification to the second relay apparatus and waits for confirmation. This feedback loop ensures that data is successfully deleted from all storage locations, maintaining data consistency across the distributed system while preserving user accessibility during the storage phase.
2Ease of operation
If manual deletion processes are used for user data across multiple storage areas, then deletion control is improved, but administrative burden and time consumption deteriorate
Solution Approach 1:
The system performs preliminary actions by automatically initiating the deletion process across all relay apparatus storage areas as soon as a deletion request is received. Instead of requiring manual intervention at each storage location, the first relay apparatus automatically sends deletion notifications to other relay apparatuses and coordinates the deletion timing. This preliminary automation significantly reduces administrative burden and time consumption while maintaining precise deletion control through the coordinated execution mechanism.

AI summary
A relay apparatus includes a memory that stores a user management table used to manage user information including state information indicating a state of a right of use of a service for every user; a receiving unit that receives a request to delete the right of use of the user from a client apparatus; a changing unit that changes a value of the state information about the user corresponding to the request in the state information to a value indicating deletion; a transmitting unit that transmits a response to the received request; and a process executing unit that executes a process for deleting data concerning the user the state information about whom has the value indicating the deletion from a storage area of the relay apparatus, in which the data is stored, and a storage area of another relay apparatus, in which the data is stored, at predetermined timing.
