A new study published on arXiv investigates the impact of pretraining data on the privacy-utility trade-off in medical image analysis models. Researchers found that the domain of the pretraining data, specifically using chest radiographs, significantly improved diagnostic accuracy under differential privacy compared to generic datasets like ImageNet. Even when the pretraining corpus itself was kept private, it still outperformed public initializations, suggesting that the source of the data is more critical than the training objective when applying privacy measures to medical imaging models.
