Development of an application for data privacy, access control and data leak

This paper presents a safe desktop client for data privacy, access control, and leakage prevention of data in high- security settings. The system incorporates Advanced Encryption Standard (AES) for encrypting files, Firebase-based multi-factor authentication for safe authentication, and Google Drive integration for encrypted cloud storage. A real-time chat feature allows safe communication, while watermarking, screenshot protection, and monitoring of access allow controlled use of data. Unlike the existing file-sharing systems, the app provides an end-to-end solution with strong cryptographic techniques, safe authentication, and cloud integration to ensure confidentiality, integrity, and availability of data. The design offers modularity to allow flexibility for future additions like watermark-based traceability and enhanced monitoring features.
