Abstract
The “Secure File Sharing Using Access Control” project focuses on creating a secure and efficient system for sharing files with strict access control measures. The application will allow users to share files with specific individuals or groups while enforcing permissions and ensuring that files are protected against unauthorized access. The system will utilize encryption, authentication, and fine-grained access control mechanisms to provide a secure file-sharing experience. The goal is to enhance file security and privacy while enabling flexible and controlled sharing options.
Existing System
Current file-sharing solutions often include cloud storage services, email attachments, and peer-to-peer file transfer applications. However, these systems may lack robust access control features or rely on basic authentication methods, which can lead to security vulnerabilities and unauthorized access. Existing solutions may also struggle with managing granular permissions or ensuring that files are adequately protected both during transit and at rest.
Proposed System
The proposed “Secure File Sharing Using Access Control” system will offer a secure platform for sharing files with advanced access control features. Users will be able to share files with specific individuals or groups, set detailed permissions (view, edit, download), and enforce encryption to protect files during transfer and storage. The system will also provide authentication mechanisms to verify user identities and ensure that only authorized individuals can access the shared files.
Methodologies
- Agile Methodology: Employ Agile practices for iterative development, allowing for continuous improvement based on user feedback and testing.
- Prototyping: Develop prototypes to test core functionalities such as access control, file encryption, and user authentication, refining features based on user experience.
- Model-View-Controller (MVC) Architecture: Use MVC architecture to separate the user interface from application logic and data management, ensuring a modular and maintainable design.
Technologies Used
- Android SDK: For developing the mobile application, including user interface design and core functionalities.
- Java/Kotlin: Programming languages used for Android development.
- Encryption Algorithms: For encrypting files both during transfer and at rest, such as AES (Advanced Encryption Standard).
- Authentication Protocols: For verifying user identities, such as OAuth 2.0 or JWT (JSON Web Tokens).
- Cloud Storage Services: For storing and managing files, such as Google Cloud Storage or AWS S3.
- Access Control Mechanisms: For managing permissions and controlling file access, such as Role-Based Access Control (RBAC) or Attribute-Based Access Control (ABAC).
System Features
- File Encryption: Encrypts files before transfer and storage to protect them from unauthorized access.
- Granular Access Control: Allows users to set detailed permissions for shared files, including view, edit, and download rights.
- User Authentication: Implements authentication mechanisms to verify user identities and ensure secure access to the system.
- Access Logs: Maintains logs of file access and sharing activities, providing an audit trail for security and compliance purposes.
- Secure File Sharing: Enables users to share files with specific individuals or groups, ensuring that only authorized recipients can access the files.
- User Management: Provides functionality for managing user accounts, roles, and permissions within the system.
- Notifications: Sends notifications to users when files are shared, accessed, or modified, keeping them informed about file activities.
