The objective of this project is to design and develop a Secure File Sharing System that dynamically adjusts user permissions based on trust evaluation. The system ensures secure file access, monitors user behavior, and modifies permissions in real time to enhance data protection and adaptive access control.
Study traditional file sharing systems and their security limitations.
Analyze trust-based access control models and dynamic permission mechanisms.
Prepare Software Requirement Specification (SRS) and system workflow documentation.
Design system architecture including authentication module, trust engine, and file management service.
Create database schema for users, files, permissions, trust scores, and activity logs.
Implement secure user authentication with password hashing and session management.
Develop modules for file upload, download, update, delete, and sharing.
Implement initial role-based permissions (Admin, Manager, User).
Design trust score calculation logic based on user activity, login behavior, and file access patterns.
Dynamically adjust user permissions when trust score increases or decreases.
Implement alerts for suspicious activities and unauthorized access attempts.
Maintain audit logs to track trust changes and file operations.
Apply encryption techniques for file storage (MCA-level enhancement).
Perform unit testing and integration testing for trust-based permission changes.
Simulate malicious behavior and validate adaptive access restrictions.
Prepare documentation including ER diagrams, trust evaluation flowcharts, and test cases.
Deploy the system locally or on a cloud simulation environment for demonstration.
