On Properties and Optimization of Information-theoretic Privacy Watchdog
Parastoo Sadeghi, Ni Ding, Thierry Rakotoarivelo
We study the problem of privacy preservation in data sharing, where is a sensitive variable to be protected and is a non-sensitive useful variable correlated with . Vari…
Low Influence, Utility, and Independence in Differential Privacy: A Curious Case of
Rafael G. L. D'Oliveira, Salman Salamatian, Muriel Médard +1
We study the relationship between randomized low influence functions and differentially private mechanisms. Our main aim is to formally determine whether differentially private mec…
Differentially Private Mechanisms for Count Queries
Parastoo Sadeghi, Shahab Asoodeh, Flavio du Pin Calmon
In this paper, we consider the problem of responding to a count query (or any other integer-valued queries) evaluated on a dataset containing sensitive attributes. To protect the p…
Independent User Partition Multicast Scheme for the Groupcast Index Coding Problem
Arman Sharififar, Neda Aboutorab, Yucheng Liu +1
The groupcast index coding (GIC) problem is a generalization of the index coding problem, where one packet can be demanded by multiple users. In this paper, we propose a new coding…
Secure Index Coding with Security Constraints on Receivers
Yucheng Liu, Parastoo Sadeghi, Neda Aboutorab +1
Index coding is concerned with efficient broadcast of a set of messages to receivers in the presence of receiver side information. In this paper, we study the secure index coding p…
Privacy-Utility Tradeoff in a Guessing Framework Inspired by Index Coding
Yucheng Liu, Ni Ding, Parastoo Sadeghi +1
This paper studies the tradeoff in privacy and utility in a single-trial multi-terminal guessing (estimation) framework using a system model that is inspired by index coding. There…
