Data reconstruction attack

WebFeb 2, 2024 · Data reconstruction attacks. Data reconstruction attacks aim to reconstruct training samples and/or associated labels accurately that were used during training. 1. DLG/iDLG. Previous work has made some contributions in inferring training data features from gradients, but these methods are generally considered “shallow” leakage. Webpaper, we study the theoretical underpinnings of a private algorithm’s resilience to reconstruction adversaries. 1.1 Contributions Our work aims to understand the data protection offered by private learners against Data Reconstruction Attacks (DRAs) by means of an information-theoretic analysis. Our contributions are summarized as follows.

WebNext, we present a full database reconstruction attack. Our algorithm runs in polynomial time and returns a poly-size encoding of all databases consistent with the given leakage profile. We implement our algorithm and observe real-world databases that admit a large number of equivalent databases, which aligns with our theoretical results. A reconstruction attack is any method for partially reconstructing a private dataset from public aggregate information. 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…
