Information Masking and Amplification: The Source Coding Setting

The complementary problems of masking and amplifying channel state information in the Gelfand-Pinsker channel have recently been solved by Merhav and Shamai, and Kim et al., respectively. In this paper, the authors study a related source coding problem. Specifically, they consider the two-encoder source coding setting where one source is to be amplified, while the other source is to be masked. In general, there is a tension between these two objectives which is characterized by the amplification-masking tradeoff. In this paper, they give a single-letter description of this tradeoff.
