Secure Source Coding with Side-information at Decoder and Shared Key at Encoder and Decoder
Hamid Ghourchian, Photios A. Stavrou, Tobias J. Oechtering +1
We study the problem of rate-distortion-equivocation with side-information only available at the decoder when an independent private random key is shared between the sender and the…
Secure Block Source Coding with Sequential Encoding
Hamid Ghourchian, Photios A. Stavrou, Tobias J. Oechtering +1
We introduce fundamental bounds on achievable cumulative rate distribution functions (CRDF) to characterize a sequential encoding process that ensures lossless or lossy reconstruct…
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…
Optimal Maximal Leakage-Distortion Tradeoff
Sara Saeidian, Giulia Cervia, Tobias J. Oechtering +1
Most methods for publishing data with privacy guarantees introduce randomness into datasets which reduces the utility of the published data. In this paper, we study the privacy-uti…
Continuous Random Variable Estimation is not Optimal for the Witsenhausen Counterexample
Maël Le Treust, Tobias Oechtering
Optimal design of distributed decision policies can be a difficult task, illustrated by the famous Witsenhausen counterexample. In this paper we characterize the optimal control de…
Fixed-Length Strong Coordination Capacity
Giulia Cervia, Tobias J. Oechtering, Mikael Skoglund
This paper investigates the problem of synthesizing joint distributions in the finite-length regime. For a fixed blocklength and an upper bound on the distribution approximatio…
