Extended Functional Representation Lemma: A Tool For Privacy, Semantic Representation, Caching, and Compression Design

Amirreza Zamani, Mikael Skoglund

This paper provides an overview of a problem in information-theoretic privacy mechanism design, addressing two scenarios in which private data is either observable or hidden. In ea…

Improving Achievability of Cache-Aided Private Variable-Length Coding with Zero Leakage

Amirreza Zamani, Mikael Skoglund

A statistical cache-aided compression problem with a privacy constraint is studied, where a server has access to a database of files, , each of size bits and…

Private Variable-Length Coding with Non-zero Leakage

Amirreza Zamani, Tobias J. Oechtering, Mikael Skoglund

A private compression design problem is studied, where an encoder observes useful data , wishes to compress it using variable length code and communicates it through an unsecure…

Multi-User Privacy Mechanism Design with Non-zero Leakage

Amirreza Zamani, Tobias J. Oechtering, Mikael Skoglund

A privacy mechanism design problem is studied through the lens of information theory. In this work, an agent observes useful data that is correlated with private…

Bounds for Privacy-Utility Trade-off with Per-letter Privacy Constraints and Non-zero Leakage

Amirreza Zamani, Tobias J. Oechtering, Mikael Skoglund

An information theoretic privacy mechanism design problem for two scenarios is studied where the private data is either hidden or observable. In each scenario, privacy leakage cons…

Data Disclosure with Non-zero Leakage and Non-invertible Leakage Matrix

Amirreza Zamani, Tobias J. Oechtering, Mikael Skoglund

We study a statistical signal processing privacy problem, where an agent observes useful data and wants to reveal the information to a user. Since the useful data is correlated…
