Rényi Pufferfish Privacy with Gaussian-based Priors: From Single Gaussian to Mixture Model
This paper develops improved Gaussian mechanisms for Rényi Pufferfish Privacy (RPP) by incorporating Gaussian and Gaussian-mixture priors, significantly reducing the required noise and improving the privacy-utility trade-off.
$α$-Wasserstein Mechanism for Rényi Pufferfish Privacy
The paper introduces the $\alpha$-Wasserstein mechanism to achieve Rényi Pufferfish Privacy using Laplace and Gaussian noise, demonstrating that it generalizes existing privacy frameworks and reduces noise power.
