Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information management systems fail to prevent the inappropriate use of personal information when users neglect to update their census registration information, leading to potential misuse of outdated personal data.
Innovation Solution
An information management system that includes a personal information appropriateness/determination section to verify the accuracy of personal information before allowing access, using a decryption key management system with blockchain to control access and track usage, ensuring only appropriate information is accessed and used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system transmits updated personal information to the organization's server when users conduct formalities, then the organization can maintain personal information databases, but inappropriate or outdated personal information may continue to be used when users neglect to update their information
Solution Approach 1:
The system implements a feedback mechanism by notifying users when their personal information has been updated in the census registration system. This feedback loop ensures users are aware of changes and can proactively update their information in the organization's database, preventing the use of outdated information while maintaining system reliability
Solution Approach 2:
The system performs preliminary actions by automatically detecting when personal information has been updated in the census registration system before the user has a chance to neglect the update. By proactively identifying updates and notifying users, the system prevents the problem of outdated information from occurring in the first place
2Productivity
If the system provides access to personal information to requesting entities, then information can be utilized for its intended purpose, but inappropriate personal information may be accessed and misused
Solution Approach 1:
The system performs preliminary verification to determine the appropriateness of personal information before granting access to requesting entities. By checking whether information has been updated and is current before providing access, the system prevents misuse of inappropriate information while still enabling productive utilization of accurate data
Solution Approach 2:
The system acts as an intermediary between the personal information database and requesting entities by implementing an appropriateness determination step. This intermediary function filters and validates information before it reaches requesting entities, preventing misuse while maintaining productive information flow

AI summary
In an information management system that manages encrypted personal information on a user stored in a storage device, a personal information appropriateness/inappropriateness determination section determines whether or not the personal information stored in the storage device is appropriate when access permission information is received from a user terminal used by the user, the access permission information instructing that a requesting entity requesting the personal information be permitted to access the personal information. A personal information access management section enables the requesting entity to access the personal information stored in the storage device when it is determined by the personal information appropriateness/inappropriateness determination section that the personal information stored in the storage device is appropriate.
