Dynamic Password Encryption for Module File Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing file protection methods for module files, especially in machine learning applications, face challenges in maintaining security and efficiency, particularly when dealing with large datasets like medical images, where data upload to a server is lengthy and risks of leakage or eavesdropping are high.
Innovation Solution
A file protection method and system that intercepts data sections from a module file, encrypts them using a dynamic password, and updates the file by integrating other sections, making it difficult to restore the original file, while using a storage system with a data accessing, intercepting, and encryption unit to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the module file is stored on the server to avoid leakage and eavesdropping, then security is improved, but the data processing time becomes lengthy when dealing with large datasets
Solution Approach 1:
The module file is divided into multiple data sections, with specific sections (e.g., fourth to seventh sections) being encrypted using different passwords. This segmentation allows the file to remain on the client device for fast access while protecting only the critical portions, thus reducing processing time without compromising security.
Solution Approach 2:
Different password protection levels are applied to different data sections based on their sensitivity. Critical sections use encryption while less sensitive sections remain unencrypted, enabling fast processing of non-critical data while maintaining security for important information.
2Reliability
If the entire module file is encrypted to protect security, then security is improved, but the file restoration and processing speed becomes slow
Solution Approach 1:
Only specific data sections (fourth to seventh sections) are encrypted with passwords, while other sections remain unencrypted. This selective encryption approach maintains security for critical data while allowing rapid restoration and processing of the entire file by decrypting only the necessary portions when needed.
Solution Approach 2:
Instead of encrypting the entire file, only the essential data sections are encrypted. This partial action approach provides sufficient security protection while minimizing the impact on file restoration speed and overall processing efficiency.

AI summary
A file protecting method having following steps is provided: intercepting a data section in a module file, encrypting the data section according to a dynamic password; integrating other data sections that are not intercepted in the module file to update the module file, and storing the updated module file, the encrypted data section and the dynamic password. A corresponding data processing system is also provided.
