An Extension of the Adversarial Threat Model in Quantitative Information Flow
Mohammad Amin Zarrabian, Parastoo Sadeghi
In this paper, we propose an extended framework for quantitative information flow (QIF), aligned with the previously proposed core-concave generalization of entropy measures, to in…
An Algorithm for Enhancing Privacy-Utility Tradeoff in the Privacy Funnel and Other Lift-based Measures
Mohammad Amin Zarrabian, Parastoo Sadeghi
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…
-leakage by Rényi Divergence and Sibson Mutual Information
Ni Ding, Mohammad Amin Zarrabian, Parastoo Sadeghi
For , this paper proposes a -mean information gain measure. Rényi divergence is shown to be the maximum -mean information g…
Privacy-Utility Tradeoff Based on -lift
Mohammad Amin Zarrabian, Parastoo Sadeghi
Information density and its exponential form, known as lift, play a central role in information privacy leakage measures. -lift is the power-mean of lift, which is tunable betwe…
A Cross Entropy Interpretation of R{é}nyi Entropy for -leakage
Ni Ding, Mohammad Amin Zarrabian, Parastoo Sadeghi
This paper proposes an -leakage measure for by a cross entropy interpretation of R{é}nyi entropy. While Rényi entropy was originally defined as an -mean for…
On the Lift, Related Privacy Measures, and Applications to Privacy-Utility Tradeoffs
Mohammad Amin Zarrabian, Ni Ding, Parastoo Sadeghi
This paper investigates lift, the likelihood ratio between the posterior and prior belief about sensitive features in a dataset. Maximum and minimum lifts over sensitive features q…
Asymmetric Local Information Privacy and the Watchdog Mechanism
Mohammad Amin Zarrabian, Ni Ding, Parastoo Sadeghi
This paper proposes a novel watchdog privatization scheme by generalizing local information privacy (LIP) to enhance data utility. To protect the sensitive features correlated…
Enhancing Utility in the Watchdog Privacy Mechanism
Mohammad Amin Zarrabian, Ni Ding, Parastoo Sadeghi +1
This paper is concerned with enhancing data utility in the privacy watchdog method for attaining information-theoretic privacy. For a specific privacy constraint, the watchdog meth…
-Information-theoretic Privacy Watchdog and Optimal Privatization Scheme
Ni Ding, Mohammad Amin Zarrabian, Parastoo Sadeghi
This paper proposes an -lift measure for data privacy and determines the optimal privatization scheme that minimizes the -lift in the watchdog method. To release data tha…
Multirate Packet Delivery In Heterogeneous Broadcast Networks
Mohammad A. Zarrabian, Foroogh S. Tabataba, Sina Molavipour +1
In this paper, we study the problem of multirate packet delivery in heterogeneous packet erasure broadcast networks. The technical challenge is to enable users receive packets at d…
