Data reconstruction attack
Webinstantiating concrete attacks, we show it is feasible to reconstruct the remaining data point in this stringent threat model. For convex models (e.g. logistic regression), reconstruction attacks are simple and can be derived in closed-form. For more general models (e.g. neural networks), we propose an attack strategy WebAug 5, 2024 · Differential privacy can protect the published data by creating uncertainty. Although readers may think that the reconstruction of a block with just seven people is an insignificant risk for the country as a whole, this attack can be performed for virtually every block in the United States using the data provided in the 2010 census.

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. 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.
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… WebApr 14, 2024 · DLG [ 39] is a typical reconstruction attack in FL, which has been introduced in Sect. 2.3.
