The paper introduces DNA, a system that enhances decentralized contact tracing by combining statistical inference with a differentially private neural network. By ensuring the neural augmentation satisfies differential privacy, the method improves detection of potentially infected individuals even at a privacy budget of epsilon=1 per message. Simulation results suggest that this approach can reduce infection rates through more targeted testing.

The paper introduces a lightweight screening tool that evaluates individual patient vulnerability to membership inference attacks across thousands of medical AI models. By measuring attack scores for each patient, the authors found that certain records consistently rank high in risk regardless of training settings, and that stronger weight decay can reduce overall exposure but not the identity of the most at‑risk patients. The tool uses four small models to flag high‑risk patients before a production model is trained, aiming to integrate privacy assessment into clinical AI data preparation.
