Typically, the dataset contains sensitive information about individuals, whose privacy needs to be protected. The attacker has no or only partial access to the dataset, but has access to public aggregate statistics about the datasets, which could be exact or distorted, for example by adding noise. If the public statistics are not sufficiently distorted, the at…

Previous work has made some contributions in inferring training data features from gradients, but these methods are generally considered “shallow” leakage. WebThere are three approaches for defending against a database reconstruction attack. The first is to publish less statistical data—this is the approach taken by legacy disclosure-avoidance techniques (cell suppression, top-coding, and generalization). The second and third approaches involve adding noise, or randomness. easy to draw taco
