Information Processing Device User Data Deletion Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a registered user is deleted or the authentication method is changed, related information may remain, compromising security as access rights information is no longer valid.
Innovation Solution
An information processing device with a reception unit for deleting preregistered users and a storage unit for related information, ensuring that all related information is deleted upon user deletion or authentication method changes, thus maintaining security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user information is deleted from the storage unit, then storage space is freed and user data is removed, but related information may remain in the storage unit compromising security
Solution Approach 1:
The patent extracts and identifies all information associated with a user from the storage unit, including user information, image data, and other related information. When user deletion is requested, the system comprehensively removes all extracted information to ensure no residual data remains that could compromise security.
Solution Approach 2:
The system provides feedback to the user about what information will be deleted before the deletion occurs. The notification unit informs users of the deletion target and scope, allowing users to confirm or cancel the deletion operation, ensuring informed consent and preventing accidental data loss.
2Reliability
If authentication method is changed for a user, then new authentication security is implemented, but old related information may remain creating security vulnerabilities
Solution Approach 1:
The system performs preliminary identification of all information associated with a user before the authentication method is changed. By pre-identifying user information, image data, and other related information, the system ensures that all relevant data is accounted for and can be properly managed during the authentication method transition.
Solution Approach 2:
When authentication method changes are detected, the system extracts and identifies all information related to the affected user from the storage unit. This comprehensive extraction ensures that no residual information from the old authentication method remains, eliminating security vulnerabilities while managing the complexity of information tracking.
3Productivity
If only user information is deleted without removing related information, then deletion process is simple and fast, but security is compromised due to remaining data
Solution Approach 1:
The system automatically identifies and manages all information related to a user without requiring manual intervention. The identification unit autonomously detects user information, image data, and other related information, and the deletion unit automatically removes all identified data when deletion is requested, maintaining both speed and security.
Solution Approach 2:
The notification unit provides feedback to users about the complete scope of information that will be deleted, including not just user information but also all related image data and other associated information. This transparent feedback mechanism ensures users understand the full impact of deletion while the system efficiently processes the removal of all identified data.

AI summary
An information processing device includes a reception unit that receives an instruction to delete a preregistered user, a storage unit that stores related information that relates to a process that the user executes on the information processing device itself, and a deletion unit that deletes the related information stored in the storage unit corresponding to a user targeted for deletion received by the reception unit.
