🛡️ DigiVault — AI-Powered Secure Document Vault

Store. Protect. Understand. Automate.

🚀 Inspiration

People usually store important documents in random folders, cloud drives, or devices and often forget them until something expires or becomes urgently needed.

We wanted to build a smarter solution — not just file storage, but an intelligent digital vault capable of understanding documents, monitoring expiry dates, and helping users interact with their files securely.

This led to DigiVault, an AI-powered secure document management platform built with MERN, automation, OCR, and RAG-based intelligence.

🧠 What DigiVault Does

DigiVault securely stores documents while adding AI-driven intelligence and automation.

Users can:

✅ Upload and securely manage documents
✅ Chat with PDFs using RAG + Gemini AI
✅ Automatically detect expiry dates using OCR
✅ Receive proactive expiry reminders
✅ Share files securely with expiration controls and passwords
✅ Enable enterprise-grade security features

The system transforms static documents into an intelligent and searchable knowledge system.

🔐 Security Features

DigiVault focuses heavily on privacy and security:

• JWT Authentication with HTTP-only cookies
• Google Authenticator based 2FA
• Email OTP recovery workflow
• Password hashing using bcryptjs
• PIN-protected file sharing
• Auto-expiring public links
• Access logs with IP tracking
• Forced revocation of shared links

🧠 Intelligence Layer

📄 Document Chat (RAG Pipeline)

Users can interact with uploaded documents naturally:

PDF → Text Extraction → Chunking → Gemini AI → Contextual Answers


Example:

“What is the premium amount in this policy?”

🔍 OCR Expiry Detection

Documents such as passports, insurance files, IDs, and certificates are scanned automatically.
