🛡️Cyprus : PII Protect System

AI-Powered Sensitive Data Detection, Masking & Secure Document Management

---

🌟 Overview

PII Protect System is a secure web platform designed to detect, mask, encrypt, and manage Personally Identifiable Information (PII) from user-uploaded documents.

Using OCR, AI-based PII detection, and AES-256 encryption, the system enables:

• Safe document upload
• Automatic PII extraction
• User-controlled masking/revealing
• Secure encrypted storage
• Manager-level controlled access

---

🔄 System Workflow

User Upload → OCR → PII Detection → Masking → Encryption → Secure Storage → Manager Access

---

✨ Features

Feature	Description
OCR Extraction	Uses Tesseract to read text from images
PII Detection	Detects Aadhaar, PAN, phone, email, address, etc.
Custom Masking	Partially or fully masks sensitive elements
User Access Control	User decides if the PII should be revealed or hidden
Manager Verification System	Manager must authenticate using ID
AES-256 Encryption	Every extracted PII text is encrypted
Secure Blob Storage	Masked files stored as encrypted blob objects
Audit Logs	Tracks every access request
