Performance Analysis of Order Statistical Patchwork schemes, which achieves significant improvements over conventional patchwork. First, we show that, when the mean comparison in patchwork is replaced by the median comparison, we get PSNR improvement due to informed watermarking. Second, we propose a majority voting scheme of a sequential comparison

Antonio Volpi,Lawrence Stanberryfor analytical purposes. A formula for the capacity of distortion-compensated quantization index modulation with lattice partitioning is given for the case of equiprobable symbols. The scalar case is analyzed in detail and a novel approximation to the optimal distortion compensation parameter is pro

Neisseria gonorrhoeae Infectionsulations. To maximize generality, the embedder is not allowed to know anything about how the simulations work, so they are referred to as “black-box channel models”. The detector is assumed to have no knowledge of either the original cover work or the channel model..A simple, iterative embedding alg

History of Sexually Transmitted Infections we go over some general concepts and ideas that apply to steganography and steganalysis. Specifically we establish a framework and define notion of security for a steganographic system. We show how conventional definitions do not really adequately cover image steganography and an provide alternate

Although the design of secure cryptographic protocols is more or less well-understood, the combination of watermarks
