Privacy-by-Design Demo

This example demonstrates MAIF's comprehensive privacy features including encryption, anonymization, and access control.

Overview

The Privacy Demo showcases MAIF's built-in privacy engine with multiple privacy levels, encryption modes, and differential privacy.

Key Features

• Encryption: AES-GCM, ChaCha20-Poly1305 for data at rest
• Privacy Levels: PUBLIC, CONFIDENTIAL, SECRET with different protections
• Anonymization: Automatic PII detection and redaction
• Access Control: Role-based permissions with audit logging
• Differential Privacy: Statistical privacy for aggregate queries

Running the Demo

cd examples/security
python3 privacy_demo.py

Code Example

from maif.core import MAIFEncoder
from maif.privacy import PrivacyEngine, PrivacyPolicy, PrivacyLevel, EncryptionMode

# Create encoder with privacy enabled
encoder = MAIFEncoder("private.maif", agent_id="privacy_demo", enable_privacy=True)

# Create privacy policy
policy = PrivacyPolicy(
    privacy_level=PrivacyLevel.CONFIDENTIAL,
    encryption_mode=EncryptionMode.AES_GCM,
    anonymization_required=True
)

# Add encrypted content
confidential_text = "Employee John Smith from john.smith@company.com"
encoder.add_text_block(
    confidential_text,
    metadata={"description": "HR record"},
    privacy_policy=policy,
    anonymize=True
)

# Finalize with encryption
encoder.finalize()
