Latest Patents

One of Grassal's latest patents is focused on an interpretability framework for differentially private deep learning. This patent describes a method where data is received that specifies a bound for an adversarial posterior belief ρ, which corresponds to a likelihood of re-identifying data points from a dataset based on a differentially private function output. The privacy parameters ε and δ are calculated based on the received data, which govern a differential privacy (DP) algorithm to be applied to a function evaluated over a dataset. The calculations are based on a ratio of probability distributions of different observations, which are bound by the posterior belief ρ as applied to the dataset. The calculated privacy parameters are then utilized to apply the DP algorithm to the function over the dataset. Related apparatus, systems, techniques, and articles are also described in this patent.
