USB Cloud Disk Block Mapping for Secure Data Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cloud storage solutions lack robust security measures and efficient data management mechanisms, particularly when accessing and managing data stored in remote repositories, and there is a need for a system that can securely store, read, modify, and delete data using a USB-based cloud disk.
Innovation Solution
A USB-based cloud disk system that includes a computer processor, storage unit, storage space configuration management unit, and block data connection unit, which manages remote repository configurations and transmits sector data through a communication unit, allowing secure storage, reading, and deletion of data by mapping virtual and remote space block IDs, enhancing data security and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If data is stored in a remote repository without block division, then data accessibility is improved, but data security deteriorates
Solution Approach 1:
The patent divides data into multiple blocks before storing in the remote repository. Each block is assigned a unique block ID and stored at different locations. This segmentation ensures that even if one block is compromised, the entire dataset remains secure, while the system can still retrieve and reconstruct complete data files by assembling the blocks.
2Object-affected harmful factors
If a USB-based cloud disk system is implemented, then data security is improved, but device complexity increases
Solution Approach 1:
The patent introduces a USB-based cloud disk system that acts as an intermediary between the user and the remote repository. This system handles the complex operations of block division, encryption, and data management, while presenting a simple interface to users. The USB device serves as a local cache and management layer, abstracting away the complexity of distributed storage from the end user.
3Productivity
If sector data is mapped to remote repository locations, then data management efficiency is improved, but configuration management complexity increases
Solution Approach 1:
The patent pre-establishes a mapping relationship between sector data and remote repository locations during the initialization phase. This mapping table is stored locally in the USB-based cloud disk, allowing the system to quickly retrieve and manage data locations without complex real-time calculations. The preliminary configuration enables efficient data access while simplifying ongoing management operations.
Data Source
AI summary
A USB-based cloud disk according to an embodiment is connected with a computer, and, when a write command on a sector is received from the computer, the USB-based cloud disk transmits data regarding the sector and a data path regarding the sector data to a remote repository.
