Extremal Mechanisms for Pointwise Maximal Leakage

2023 · arXiv (Cornell University)

Data publishing under privacy constraints can be achieved with mechanisms that add randomness to data points when released to an untrusted party, thereby decreasing the data's utility. In this paper, we analyze this privacy-utility tradeoff …

Private Variable-Length Coding with Zero Leakage

2023 · arXiv (Cornell University)

A private compression design problem is studied, where an encoder observes useful data $Y$, wishes to compress it using variable length code and communicates it through an unsecured channel. Since $Y$ is correlated with private …
