-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…
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…
Kantorovich Mechanism for Pufferfish Privacy
Ni Ding
Pufferfish privacy achieves -indistinguishability over a set of secret pairs in the disclosed data. This paper studies how to attain -pufferfish privacy by exponential mechan…
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…
