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…
Measuring Information Leakage in Non-stochastic Brute-Force Guessing
Ni Ding, Farhad Farokhi
This paper proposes an operational measure of non-stochastic information leakage to formalize privacy against a brute-force guessing adversary. The information is measured by non-p…
-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…
A Linear Reduction Method for Local Differential Privacy and Log-lift
Ni Ding, Yucheng Liu, Farhad Farokhi
This paper considers the problem of publishing data while protecting correlated sensitive information . We propose a linear method to generate the sanitized data with th…
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…
