Feedback Coding Enables Inference-Time Covert Agentic Communication
Sidong Guo, Sajani Vithana, Atefeh Gilani +3
As large language models (LLMs) are increasingly used to automate digital interactions, users can leverage LLM-generated text as cover for covert communication within seemingly ben…
An information theorist's tour of differential privacy
Anand D. Sarwate, Flavio P. Calmon, Oliver Kosut +1
Since being proposed in 2006, differential privacy has become a standard method for quantifying certain risks in publishing or sharing analyses of sensitive data. At its heart, dif…
Optimizing Noise Distributions for Differential Privacy
Atefeh Gilani, Juan Felipe Gomez, Shahab Asoodeh +3
We propose a unified optimization framework for designing continuous and discrete noise distributions that ensure differential privacy (DP) by minimizing Rényi DP, a variant of DP,…
Reveal-or-Obscure: A Differentially Private Sampling Algorithm for Discrete Distributions
Naima Tasnim, Atefeh Gilani, Lalitha Sankar +1
We introduce a differentially private (DP) algorithm called reveal-or-obscure (ROO) to generate a single representative sample from a dataset of observations drawn i.i.d. from…
Unifying Privacy Measures via Maximal -Leakage (MbeL)
Atefeh Gilani, Gowtham R. Kurri, Oliver Kosut +1
We introduce a family of information leakage measures called maximal -leakage (MbeL), parameterized by real numbers and greater than or equal to 1. The measure is…
An Alphabet of Leakage Measures
Atefeh Gilani, Gowtham R. Kurri, Oliver Kosut +1
We introduce a family of information leakage measures called maximal -leakage, parameterized by real numbers and . The measure is formalized via an operational definiti…
