Local Obfuscation Mechanisms for Hiding Probability Distributions
Yusuke Kawamoto, Takao Murakami
We introduce a formal model for the information leakage of probability distributions and define a notion called distribution privacy as the local differential privacy for probabili…
Hybrid Statistical Estimation of Mutual Information and its Application to Information Flow
Fabrizio Biondi, Yusuke Kawamoto, Axel Legay +1
Analysis of a probabilistic system often requires to learn the joint probability distribution of its random variables. The computation of the exact distribution is usually an exhau…
On the Anonymization of Differentially Private Location Obfuscation
Yusuke Kawamoto, Takao Murakami
Obfuscation techniques in location-based services (LBSs) have been shown useful to hide the concrete locations of service users, whereas they do not necessarily provide the anonymi…
Utility-Optimized Local Differential Privacy Mechanisms for Distribution Estimation
Takao Murakami, Yusuke Kawamoto
LDP (Local Differential Privacy) has been widely studied to estimate statistics of personal data (e.g., distribution underlying the data) while protecting users' privacy. Although…
Leakage and Protocol Composition in a Game-Theoretic Perspective
Mário S. Alvim, Konstantinos Chatzikokolakis, Yusuke Kawamoto +1
In the inference attacks studied in Quantitative Information Flow (QIF), the adversary typically tries to interfere with the system in the attempt to increase its leakage of secret…
A Game-Theoretic Approach to Information-Flow Control via Protocol Composition
Mário S. Alvim, Konstantinos Chatzikokolakis, Yusuke Kawamoto +1
In the inference attacks studied in Quantitative Information Flow (QIF), the attacker typically tries to interfere with the system in the attempt to increase its leakage of secret…
