Folder Visibility Control via Access Rights Evaluation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing file management systems face high operational loads for administrators when setting access rights for electronic files and folders, and dynamically generated folders based on attribute information cannot be effectively hidden from users without access rights, leading to potential leaks of attribute information.
Innovation Solution
An information processing apparatus that includes a specifying unit for selecting folders, a determination unit to assess user access rights, and a control unit to manage the display of folders, hiding them if the user lacks access rights, thereby preventing attribute information leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access rights are set for respective electronic files and folders to hide information, then security is improved, but the operation load on administrators increases
Solution Approach 1:
The system automatically determines folder visibility by checking whether electronic files within the folder have access rights granted to the user. The folder itself does not require separate access rights configuration; instead, the system self-evaluates based on the access rights of contained files, thereby reducing administrative workload while maintaining security.
Solution Approach 2:
The access rights mechanism serves multiple functions: it controls both direct file access and indirect folder visibility. By using the same access rights system for both purposes, the patent eliminates the need for separate folder-level access right configurations, reducing complexity and administrative burden.
2Adaptability or versatility
If folders are dynamically generated based on attribute information to classify electronic files, then file classification capability is improved, but attribute information leaks via folder names
Solution Approach 1:
The patent applies different visibility rules to different folders based on their contents. Folders containing files with restricted access rights are hidden, while folders with publicly accessible files remain visible. This localized quality control ensures that attribute information is protected only where necessary, maintaining classification capability without unnecessary hiding of legitimate folders.
Solution Approach 2:
The system introduces an intermediary evaluation mechanism that checks the access rights status of electronic files within a folder before determining the folder's visibility. This intermediary layer prevents direct exposure of attribute information through folder names while maintaining the dynamic classification structure.
3Reliability
If access rights are set for each folder to prevent attribute information leakage, then information security is improved, but the complexity of access right management increases
Solution Approach 1:
The patent extracts the access right evaluation logic from the folder level and relocates it to the electronic file level. Instead of managing access rights for folders, the system evaluates access rights of individual files within folders. This extraction simplifies the management structure by eliminating redundant folder-level access right configurations.
Solution Approach 2:
The patent merges the folder visibility control function with the electronic file access right management system. By combining these two functions into a single evaluation mechanism, the system reduces the overall complexity of access right management while maintaining information security.

AI summary
Embodiments of the invention are directed to a display control method in an information processing apparatus, which can display a hierarchical structure of folders, which can classify and store electronic files according to attribute information, using folder names based on attribute information. The method includes specifying a folder to be displayed and electronic files classified to the folder in response to an instruction from a user, determining whether or not the specified folder includes electronic files, access rights of which are granted to the user. The method also includes controlling display of the specified folder when the specified folder includes electronic files, the access rights of which are granted to the user, and controlling hiding of the specified folder when the specified folder does not include any electronic files, the access rights of which are granted to the user.
