A new research paper introduces the concept of Real-Synthetic Mix-Training (RSMT), a common practice of augmenting real datasets with synthetic data generated by text-to-image models. The study reveals that this method, rather than enhancing privacy, can significantly amplify privacy risks for the real data that remains in the training set. Researchers developed a theoretical framework, RSMT Memorization Amplification, and a tool called RSMixLeak to demonstrate how models are forced to memorize real samples more aggressively when trained with synthetic data, leading to increased privacy leakage.

IMPACT This research highlights a critical privacy concern in AI model training, suggesting that current practices of mixing synthetic and real data may inadvertently increase the vulnerability of sensitive real-world information.
