Web Storage File Management Preventing Data Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional file management methods in web storage systems fail to prevent data leakage by allowing temporary storage of sensitive files on user terminals and do not facilitate secure transfer of files to other users without managerial approval.
Innovation Solution
A file management method where files of specific types are monitored and deleted from user terminals, stored only in a web storage system, and managed through a DBMS, with all file operations processed as a single transaction to prevent data remnants on terminals, and secure transfer allowed only with managerial approval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If files are stored in local PC for temporary storage during creation or update, then ease of operation is improved, but data leakage risk increases
Solution Approach 1:
The patent extracts the file storage function from the local PC by implementing a web-based file management system. Files are created, stored, and managed through a web interface without being saved to the local filesystem. The server handles all file operations, and only file data is transmitted to the server, eliminating the harmful effect of data remaining on local devices while maintaining operational ease through web-based access.
2Object-affected harmful factors
If file monitoring and deletion is implemented, then data leakage prevention is improved, but device complexity increases
Solution Approach 1:
The patent introduces a web-based file management system as an intermediary between the user and the file storage. This intermediary handles all file operations through a web interface, monitoring and controlling file storage without requiring complex local software or system modifications. The server acts as the mediator that implements monitoring and deletion policies, simplifying the overall system architecture while maintaining strong security.
3Object-affected harmful factors
If approval process for file transfer is added, then security is improved, but loss of time increases
Solution Approach 1:
The patent implements preliminary action by requiring managerial approval before file transfer occurs. The system monitors file operations and automatically initiates the approval process, so that when a user attempts to transfer a file, the approval status is already checked and decided in advance. This prevents unauthorized transfers while minimizing time delay by making the approval decision point-in-time rather than requiring continuous manual intervention.

AI summary
The present invention relates to a file management method in a web storage system, and more specifically, to a file management method in a web storage system, in which when a user connects to the web storage system and creates, updates and stores files, files of a specific type are all deleted from a local PC and stored only in a file management system, and thus none of data is stored in the local PC.According to the present invention, when a file is created and stored using a web storage system, none of data related to a file that may cause a security problem remains in a user terminal of a remote site, and thus a file leakage problem may be cleared.
