Document Storage System Using Folder Memory Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Document storage and retrieval systems are vulnerable to unauthorized access, particularly 'hacking' into electronic versions of documents, which compromises confidential information.
Innovation Solution
The system stores only document identification data and location information in the mass storage device, with the electronic version of the document stored in a file folder memory that can only be accessed by removing the folder from a cabinet, and a reader device is used to display the document, ensuring that the host computer cannot access the electronic version after initial storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic version of the document is stored in the mass storage device connected to the host computer, then the document can be easily accessed and retrieved by the host computer, but the system becomes vulnerable to unauthorized access and hacking
Solution Approach 1:
The electronic version of the document is extracted from the centralized mass storage device and stored locally in the file folder memory. This distributes the document data across multiple independent locations (host computer mass storage, file folder memory, and physical document), so that compromising one location does not expose the complete document. The file folder memory becomes a separate, portable storage unit that can be physically removed from the cabinet, creating isolation between the host computer's access capabilities and the actual document data.
2Object-affected harmful factors
If the electronic version of the document is stored in the file folder memory that can only be accessed by removing the folder from the cabinet, then security against unauthorized access is improved, but the ease of retrieving and displaying the document is reduced
Solution Approach 1:
The reader device serves as an intermediary between the file folder memory and the user. Instead of requiring direct connection between the host computer and the file folder memory, the reader device acts as a mediator that can read the electronic document from the file folder memory and display it on its screen. This intermediary layer maintains security by preventing direct host computer access to the file folder memory while still enabling convenient document retrieval and viewing through the reader device's display interface.
3Object-affected harmful factors
If the host computer cannot access the electronic version of the document after initial storage, then security is enhanced, but the ability to retrieve and process the document through the host computer is limited
Solution Approach 1:
The document exists in multiple segmented forms across different storage locations: the host computer stores only document identification data and location information in its mass storage device, while the actual electronic version is stored separately in the file folder memory. This segmentation means that even if the host computer's database is compromised, the actual document content remains protected in the separate file folder memory. The system maintains versatility by allowing documents to be accessed through multiple paths: the host computer can manage document metadata and locations, while the reader device can retrieve and display the actual document content from the file folder memory.

AI summary
A document storage and retrieval system for securely storing documents. A mass storage device contains document identification data and document location information but not the document data. A host computer extracts the document identification data and document location information from the mass storage device and sends this information to a storage cabinet containing the document. Each document is removably stored in a file folder contained in a cabinet drawer. Each file folder has a memory unit which stores an electronic version of each physical document contained in the file folder. The host computer directs the initial storage of a document in folder memory. Thereafter, the host computer is denied access to the electronic versions stored in file folder memory. Access to the electronic versions is only possible using a special reader device.
