File Splitting Across Devices for Secure Backup Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing file backup solutions on terminal equipment are insecure, as files stored externally are vulnerable to leakage, leading to potential loss due to unauthorized access or network breaches.
Innovation Solution
A method for processing files by splitting them into sub-files stored across multiple devices, where the core portion containing essential information is stored locally and the additional portion is stored in a cloud server, ensuring that even if one sub-file is leaked, the original content remains secure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If files are stored in another equipment for backup, then storage space of terminal equipment is released, but file security deteriorates due to vulnerability to leakage
Solution Approach 1:
The patent divides a file into multiple sub-files and stores them in different equipment locations (terminal equipment and cloud server). This segmentation ensures that even if one location is compromised, the complete file cannot be reconstructed, thus maintaining security while enabling backup storage.
Solution Approach 2:
The patent introduces an encryption mechanism as an intermediary between the file and storage locations. The file is encrypted before being split and stored, and only the authorized user with the decryption key can reconstruct and access the original file, thereby securing the backup process.
2Reliability
If files are encrypted and split into sub-files stored in multiple locations, then file security is improved, but system complexity increases
Solution Approach 1:
The patent implements automatic encryption and file splitting mechanisms that operate transparently to the user. The system automatically manages the complexity of encryption algorithms and file segmentation without requiring user intervention, thus improving security while minimizing the perceived complexity for users.
Solution Approach 2:
The patent creates a multi-functional system that simultaneously performs encryption, file splitting, distributed storage, and automatic reconstruction. This universal approach consolidates multiple security functions into a single integrated system, reducing overall complexity compared to implementing separate solutions for each function.

AI summary
Embodiments of the present application provide a file processing method, a file processing device, an electronic apparatus, and a readable storage medium. The method comprises: receiving an operation request for a file, the file comprising at least two sub-files separately stored in at least two equipments; and correspondingly processing at least one sub-file of the file according to the operation request. By the solutions provided in the embodiments of the present application, since at least two sub-files of a file are separately stored in at least two equipments, original contents of the file cannot be obtained even if a sub-file in one equipment is leaked. By the solutions provided in the embodiments of the present application, the security of files can be effectively improved.
