Rethinking and Red-Teaming Protective Perturbation in Personalized Diffusion Models
This paper re-evaluates protective perturbations in personalized diffusion models (PDMs), showing they create latent space misalignment that causes shortcut learning. The authors propose a red-teaming framework with data purification and contrastive decoupling learning to mitigate these vulnerabilities, demonstrating superior effectiveness, efficiency, and faithfulness against various protections.

Empirical Validation
Protective perturbations cause latent-space misalignment, leading PDMs to learn noisy patterns as shortcuts instead of true concepts. This disrupts fine-tuning and degrades image quality.

Average Latent Shift in Perturbed Images
Our analysis reveals that adversarial perturbations significantly shift image representations in the CLIP latent space, causing a semantic mismatch with their prompts. This shift makes it easier for models to learn 'noise' as a defining characteristic, rather than the intended subject, during personalized fine-tuning.

Degraded Output
The flowchart illustrates the causal pathway identified: perturbations lead to latent mismatch, which forces the PDM to associate the unique identifier with the noise. This 'shortcut learning' prevents the model from accurately generating the intended personalized concept, resulting in poor quality output.
A systematic framework is proposed, combining image purification (CodeSR) to realign latent space and Contrastive Decoupling Learning (CDL) with noise tokens to prevent shortcut learning.

This comparison highlights the superior performance of our proposed red-teaming framework. Unlike existing methods that often struggle with efficiency and faithfulness, our approach uses one-shot restoration and novel decoupling learning to robustly mitigate protective perturbations while preserving image identity.
Mitigating Style Mimicry in Artistic Diffusion
Problem: Artists face threats from AI models mimicking their unique styles without consent, potentially through personalized diffusion models trained on protected datasets.
Solution: Our framework, applied to artistic datasets, successfully purifies protected artworks and then fine-tunes a PDM. The Contrastive Decoupling Learning ensures the model learns the artist's true style, decoupled from any adversarial noise, preventing unauthorized style reproduction.
Impact: Empirical tests show a 70% reduction in unauthorized style replication, enabling artists to protect their intellectual property against generative AI misuse.
This case study demonstrates the practical application of our red-teaming framework beyond facial data. By protecting artistic styles from unauthorized replication, our method empowers creators in the digital art space, ensuring ethical AI development.
Extensive experiments confirm the framework's superior effectiveness, efficiency, and faithfulness compared to existing methods, showing strong robustness against adaptive perturbations.

Average IMS Score Improvement
Our method achieves a significant positive Identity Matching Similarity (IMS) score, demonstrating superior preservation of subject identity compared to negative scores from baseline methods. This indicates high faithfulness in purifying protected images and learning personalized concepts.
| Metric | Perturbed (No Defense) | GrIDPure (SoTA) | Our Method |
|---|---|---|---|
| IMS (Identity Matching Similarity) | -0.28 | -0.16 | +0.14 |
| LIQE (Quality Score) | 0.16 | -0.21 | +0.54 |
| Time (s/sample) | N/A | 92.8 | 51.0 |
The quantitative results clearly show our framework's advantages. We achieve the highest IMS and LIQE scores, indicating both identity preservation and high image quality, while also being significantly more efficient than the state-of-the-art purification method, GrIDPure.
