Project overview
The Secure File Sharing System was developed to provide a safe, efficient, and user-friendly platform for exchanging digital files within a tertiary institution. Students, lecturers, and administrators often share sensitive materials such as assignments, lecture notes, research papers, and administrative documents. Traditional methods of sharing—such as email attachments, flash drives, or public cloud services—pose serious risks, including unauthorized access, malware attacks, and data corruption.
This project introduces a web-based solution that integrates user authentication, role-based access control, and modern encryption algorithms (AES, DES, Blowfish) to ensure files are protected during storage and transmission. With an intuitive interface, the system strikes a balance between strong security and ease of use, making it practical for academic communities.
Project Challenges
Several challenges were encountered during the course of the project, including:
-
Encryption Integration – Implementing and optimizing multiple encryption algorithms to handle different file types and sizes efficiently.
-
Security vs. Performance – Strong encryption sometimes slowed down file transfers, requiring careful optimization.
-
Large File Handling – Ensuring smooth uploads and downloads for large files without compromising security.
-
User Experience (UX) – Designing a simple and accessible interface while maintaining advanced security features in the background.
Final results
At the end of the project, the Secure File Sharing System was successfully implemented with the following outcomes:
-
A functional platform that allows secure registration, login, file upload, and sharing.
-
File encryption and decryption using AES, DES, and Blowfish, giving users flexibility in choosing security levels.
-
Role-based access control, ensuring only authorized users can send, receive, or download files.
-
Improved confidentiality, integrity, and reliability of shared academic documents compared to traditional methods.
-
A user-friendly interface tested by sample users (students and lecturers), who found it easy to navigate.
The project demonstrated that it is possible to create a secure and efficient file sharing platform that protects sensitive academic data without sacrificing usability.
