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…
Generalization of the Fano and Non-Fano Index Coding Instances
Arman Sharififar, Parastoo Sadeghi, Neda Aboutorab
Matroid theory is fundamentally connected with index coding and network coding problems. In fact, the reliance of linear index coding and network coding rates on the characteristic…
Cooperative Jamming for Physical Layer Security Enhancement Using Deep Reinforcement Learning
Sayed Amir Hoseini, Faycal Bouhafs, Neda Aboutorab +2
Wireless data communications are always facing the risk of eavesdropping and interception. Conventional protection solutions which are based on encryption may not always be practic…
Quantifying Privacy via Information Density
Leonhard Grosse, Sara Saeidian, Parastoo Sadeghi +2
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 p…
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…
Optimal Binary Differential Privacy via Graphs
Sahel Torkamani, Javad B. Ebrahimi, Parastoo Sadeghi +2
We present the notion of \emph{reasonable utility} for binary mechanisms, which applies to all utility functions in the literature. This notion induces a partial ordering on the pe…
