Extremal mechanisms for pointwise maximal leakage

L Grosse, S Saeidian… - IEEE Transactions on …, 2024 - ieeexplore.ieee.org
Data publishing under privacy constraints can be achieved with mechanisms that add
randomness to data points when released to an untrusted party, thereby decreasing the …

An information-theoretic approach to generalization theory

B Rodríguez-Gálvez, R Thobaben… - arXiv preprint arXiv …, 2024 - arxiv.org
We investigate the in-distribution generalization of machine learning algorithms. We depart
from traditional complexity-based approaches by analyzing information-theoretic bounds …

Information Density Bounds for Privacy

S Saeidian, L Grosse, P Sadeghi, M Skoglund… - arXiv preprint arXiv …, 2024 - arxiv.org
This paper explores the implications of guaranteeing privacy by imposing a lower bound on
the information density between the private and the public data. We introduce an …

Quantifying Privacy via Information Density

L Grosse, S Saeidian, P Sadeghi, TJ Oechtering… - arXiv preprint arXiv …, 2024 - arxiv.org
We examine the relationship between privacy metrics that utilize information density to
measure information leakage between a private and a disclosed random variable. Firstly, we …

[PDF][PDF] Rethinking disclosure prevention with pointwise maximal leakage

S Saeidian, G Cervia, TJ Oechtering… - Submitted to: Journal of …, 2023 - people.kth.se
This paper introduces a paradigm shift in the way privacy is defined, driven by a novel
interpretation of the fundamental result of Dwork and Naor about the impossibility of …

A Generalization of Axiomatic Approach to Information Leakage

MA Zarrabian, P Sadeghi - arXiv preprint arXiv:2409.04108, 2024 - arxiv.org
In this paper, we extend the framework of quantitative information flow (QIF) to include
adversaries that use Kolmogorov-Nagumo $ f $-mean to infer secrets of a private system …

Evaluating Differential Privacy on Correlated Datasets Using Pointwise Maximal Leakage

S Saeidian, TJ Oechtering, M Skoglund - Annual Privacy Forum, 2024 - Springer
Data-driven advancements significantly contribute to societal progress, yet they also pose
substantial risks to privacy. In this landscape, differential privacy (DP) has become a …

An Algorithm for Enhancing Privacy-Utility Tradeoff in the Privacy Funnel and Other Lift-based Measures

MA Zarrabian, P Sadeghi - 2024 17th International Conference …, 2024 - ieeexplore.ieee.org
This paper investigates the privacy funnel, a privacy-utility tradeoff problem in which mutual
information quantifies both privacy and utility. The objective is to maximize utility while …

Pointwise Maximal Leakage: Robust, Flexible and Explainable Privacy

S Saeidian - 2024 - diva-portal.org
For several decades now, safeguarding sensitive information from disclosure has been a
key focus in computer science and information theory. Especially, in the past two decades …
