Protection Methods

Method	Description	Target
Frequency Domain Cloaking	DCT-based perturbations that survive JPEG compression	Compression-based attacks
Semantic Feature Disruption	Scrambles identity features using ArcFace, DINOv2, CLIP	Face-swap models
Latent Space Poisoning	Corrupts latent codes in deepfake model pipelines	Generative models

Usage Examples

from ml.protection import protect_image, MSAPProtector, MSAPConfig

# Quick protection
protected = protect_image(my_image)

# Custom configuration
config = MSAPConfig(
    epsilon_freq=0.03,  # Frequency perturbation budget
    epsilon_sem=0.05,   # Semantic perturbation budget
    tau=0.1,            # Latent perturbation parameter
    min_ssim=0.95       # Quality constraint
)
protector = MSAPProtector(config)
protected, info = protector.protect(my_image, return_components=True)

print(f"SSIM: {info['quality']['ssim']:.4f}")
print(f"LPIPS: {info['quality']['lpips']:.4f}")
