🛡️ PII-Shield
Your Intelligent Guardian for Personal Data Protection
🌟 What is PII-Shield?
PII-Shield is your cutting-edge solution for protecting sensitive information in text data. Powered by advanced transformer architecture, it's your first line of defense against unintended PII exposure.
🎯 Core Capabilities
🔍 Smart Detection
"Regular text with [email protected]" → "Regular text with [EMAIL_1]"
🎭 Intelligent Masking
"Call John at (555) 123-4567" → "Call [PERSON_1] at [PHONE_1]"
📊 Structured Mapping
Original → Masked → JSON Mapping
🚀 Model Architecture
🧠 Two-Stage Intelligence
⚡ Supported PII Categories
| Category | Icon | Example |
|---|---|---|
| Names | 👤 | John Smith |
| Emails | 📧 | [email protected] |
| Phones | 📱 | (555) 123-4567 |
| Addresses | 🏠 | 123 Privacy St |
| SSN | 🔢 | XXX-XX-XXXX |
| Credit Cards | 💳 | XXXX-XXXX-XXXX |
| DOB | 📅 | MM/DD/YYYY |
| IPs | 🌐 | 192.168.1.1 |
💫 How It Works

def detect_pii(text: str) -> List[Entity]:
"""
🔍 Intelligent PII detection
Returns list of identified entities
"""
pass
🎭 Masking Phase
def mask_pii(text: str, entities: List[Entity]) -> Dict:
"""
🛡️ Smart PII masking
Returns masked text and mapping
"""
pass
