Cloud Storage Data Distribution and Encryption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cloud storage security concerns arise from data interception during transmission, loss due to physical storage system crashes, and theft from inadequate provider protection, necessitating improved methods for accessing and securing data across multiple cloud storage servers.
Innovation Solution
A method and apparatus that divide and encrypt files into parts, storing them across multiple cloud storage servers managed by different providers, using a client with a communications interface to manage file uploads, authentication, and redundancy for fault-tolerant data recovery, while disguising file types to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is stored in cloud storage space provided by hosting companies, then data accessibility and storage capacity are improved, but data security deteriorates due to interception risks, physical storage crashes, and inadequate provider protection
Solution Approach 1:
The patent divides files into multiple parts and stores them across multiple cloud storage providers. Each provider only holds a fragment of the original file, making it impossible for any single provider to access or misuse the complete data. This segmentation approach maintains data accessibility while significantly improving security against interception, theft, and provider-related failures.
Solution Approach 2:
The patent introduces an intermediary client system that manages file distribution across multiple cloud providers. This intermediary layer encrypts files before distribution and coordinates recovery processes, acting as a security buffer between the user and the cloud storage providers. The intermediary ensures that no single provider has direct access to complete unencrypted data.
2Reliability
If files are divided and stored across multiple cloud storage providers, then data security and redundancy are improved, but system complexity increases
Solution Approach 1:
The patent implements automatic file segmentation, encryption, and distribution processes that occur without user intervention. The client system automatically manages the complexity of dividing files into parts, selecting appropriate cloud providers, and handling encryption/decryption operations. Users simply upload and retrieve files as if using a single storage service, while the system handles the complex multi-provider coordination in the background.
3Reliability
If file data is encrypted and distributed across multiple servers, then data protection against interception and theft is improved, but access time and retrieval complexity increase
Solution Approach 1:
The patent performs file encryption and segmentation into multiple parts before distribution to different cloud providers. This preliminary processing ensures that when files need to be retrieved, the decryption process can begin immediately once the necessary parts are assembled, minimizing access delays. The system pre-establishes the encryption keys and segmentation schemes, so no additional complex processing is needed during retrieval operations.
Data Source
AI summary
An embodiment of the invention introduces a method for accessing data in cloud storage space, which contains at least the following steps. A file is obtained. File uploads are generated, where each file upload contains partial data of the file. The file uploads are stored in storage servers of the cloud storage space, where the storage servers are governed by different cloud storage providers.
