Information Hiding Capacities in Multiple Antennas Channel Coding System

Multiple description coding for wireless channels with multiple antennas

Multiple description coding (MDC) provides error resilience by producing several descriptions of the source so that various quality reconstructions can be obtained from any subset of the descriptions. The use of correlating transforms within the MDC framework has been studied for “on-off” channels, such as packet-switched channels. Since this channel model is not appropriate for wireless system...

A Source and Channel Coding Approach to Data Hiding with Application to Hiding Speech in Video

Digital data hiding is a technology being developed for multimedia services, where non-trivial amounts of signature data is invisibly hidden inside a host data source by the owner before the latter is freely distributed. Only those authorized can recover the hidden data from the host, even after the latter has undergone standard transformations such as compression. In this work we adopt a quant...

Data Hiding System Based on New Multiple Echo Hiding Method

With the development of information society, audio steganalysis has attracted more attentions recently. Echo hiding method is one of the most challenging research fields. However, most of them can't solve the contradiction of capacity, robustness and imperceptibility, which restrict the development of the system seriously. Some of them have low capacity, and others have relatively high capacity...

Channel models for high-capacity information hiding in images

We consider the scenario of blind information hiding in images as a communications channel, where the channel noise is caused by the embedding and blind extraction method as well as by any lossy compression method utilized to store and transmit the image. We assume that the objectives of the information hiding method are the maximization of payload and its visual and statistical imperceptibilit...
