Virtual Folder Kernel Module for Cross-OS Content Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cloud computing technologies face challenges in seamlessly managing and browsing contents across different operating systems without requiring separate content conversion, as existing techniques either create separate virtual databases or manage contents through virtual folders, but fail to provide a solution for browsing contents without conversion across various OS environments.
Innovation Solution
An apparatus and method for managing security contents using a virtual folder, which includes a data control unit for receiving and storing authority policies, a security processing unit for encoding or decoding contents, and a security filesystem interface unit that creates and registers virtual folders in the kernel mode, allowing contents to be provided based on authority information without separate conversion operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate virtual database is created to manage contents across multiple user terminals, then content management capability is improved, but content conversion is required when browsing in different OS environments
Solution Approach 1:
The patent introduces a virtual folder as an intermediary layer between the physical file system and the user application. This virtual folder, created through virtualization technology, intercepts file access requests and redirects them to the appropriate locations in the physical file system, eliminating the need for content conversion across different OS environments while maintaining universal accessibility.
Solution Approach 2:
The patent segments the file management system into distinct layers: the physical file system layer, the virtual folder layer (created by the virtualization module), and the user application layer. This segmentation allows each layer to operate independently with its own characteristics, enabling the virtual folder to handle cross-OS compatibility without requiring content conversion.
2Ease of operation
If virtualization technology is used to create a virtual folder in each user terminal, then content accessibility is improved, but authority policy management becomes complex
Solution Approach 1:
The patent extracts the authority policy management function from the distributed virtual folders in user terminals and centralizes it in the server system. The server stores and manages authority policies centrally, while virtual folders in user terminals only handle local file access redirection, significantly simplifying authority policy management while maintaining content accessibility.
3Adaptability or versatility
If contents are stored in a virtual database accessible by multiple terminals, then multi-user access is improved, but content conversion is required across different OS environments
Solution Approach 1:
The virtual folder acts as an intermediary that maintains the original content format in the physical file system while providing unified access across multiple user terminals. By intercepting and redirecting file access requests, it enables multi-user access without content conversion, ensuring content browsing reliability across different OS environments.
Data Source
AI summary
Provided are an apparatus and method for managing security contents using a virtual folder. The apparatus for managing security contents includes a data control unit that receives an authority policy on contents from a security content server, and stores the received authority policy in a storage means, a security processing unit that encodes or decodes the contents based on the authority policy provided from the data control unit, and a security filesystem interface unit that creates a virtual folder based on position information of a folder to be virtualized and path information of the virtual folder by driving a virtual folder creation module that is operated in a kernel mode and registers the created virtual folder in a filesystem, and provides, to the security processing unit, contents corresponding to an input and output event for contents which have been recorded or are to be recorded in the virtual folder hooked from the kernel mode and instructs the security processing unit to encode or decode the provided contents. According to the present invention, it is possible to provide contents created in different environments to a user based on authority information without any separate content conversion operation.
