| Abstract: |
This work studies reversible information embedding, where a compressed host data is available, before transmission, at the decoder. The problem is solved for a (fixed) degraded broadcast attack channel, which corresponds to the scenario where the stegotext is subject to several stages of attack. A single letter characterization of the region of all achievable rate-distortion quadruples $(R_y,R_z,R_d,D)$ is given, where $R_y$, $R_z$ are the embedding rates, $R_d$ is the rate limit of the compressed host at the decoders, and $D$ is the average distortion between the host and the data set (stegotext). |
