Cloud-Based File Storage with Access Control is a secure web-based application designed to provide encrypted file storage with fine-grained role-based authorization. The system integrates secure authentication, AES-based file encryption, structured relational database management, activity logging, and administrative monitoring into a unified platform.

Unlike conventional file-sharing systems that focus only on storage and sharing, this system introduces an integrated security loop that authenticates, authorizes, encrypts, logs, and monitors all user actions in real time. The application employs AES encryption for file protection, Bcrypt hashing for password security, and role-based access control (RBAC) to enforce structured permission management.

By combining encryption, authentication, and system monitoring, the platform ensures confidentiality, integrity, and accountability. The project demonstrates how secure cloud storage systems can be architected using Flask, MySQL, and structured access control mechanisms to provide enterprise-level security in a scalable design.
