Transmission of Hidden Cipher Text over a Binary Symmetric Channel
A new high capacity and robust image steganography method based on human vision sensitivity is introduced. Kohonen Neural network is trained according to the contrast sensitivity of pixels present in cover image. Trained network classify the pixels of cover image in different levels of sensitivity. Data embedding is performed by LSB substitution method, which replaces the least significant bits...
متن کاملRobust Video Transmission over Binary Symmetric Channels with Packet Erasures
A video transmission system is presented based on the 3-D SPIHT algorithm for video compression and turbo codes for channel error protection. The channel considered is a binary symmetric channel with packet erasures, used for modeling the concatenation of a congested wired link followed by a noisy wireless hop. Unequal error protection with turbo codes is used for providing strong channel prote...
متن کاملOn Estimation for a Binary-Symmetric Channel
We consider a binary symmetric channel where the input, modeled as an innnite sequence of bits, is distorted by a Bernoulli noise. In 8], a consistent estimator of the distortion, i.e., of the probability that a single bit is changed, is described under the basic assumption that the complexity of the input is nite. Here, we deal with two shortcomings: 1. Simons' estimator requires some informat...
متن کاملThermodynamics of the binary symmetric channel
We study a hidden Markov process which is the result of a transmission of the binary symmetric Markov source over the memoryless binary symmetric channel. This process has been studied extensively in Information Theory and is often used as a benchmark case for the so-called denoising algorithms. Exploiting the link between this process and the 1D Random Field Ising Model (RFIM), we are able to ...
متن کاملOn the Binary Symmetric Wiretap Channel
In this paper, we investigate the binary symmetric wiretap channel. We show that the secrecy capacity can be achieved by using random linear codes. Furthermore, we explore the coset coding scheme constructed by linear codes. As a result, we give an upper bound on the total information loss, which sheds light on the design of the applicable coset codes for the secure transmission with limited in...
