In the realm of secure communication systems, the integration of advanced wavelet
transforms into speech steganography systems has emerged as a promising path. Secure …

Steganography is a technique of concealing secret information within an innocuous-looking
carrier signal. Speech steganography has become increasingly important in a variety of …

Steganography is the process of hiding information on a host signal. Transparency is
referred to the ability to avoid suspicion about the existence of a secret message. The most …

Steganography is the art of hiding information into a cover object. The cover object could be
any media like an image, audio or human speech. The essence of steganography lies in the …

Generally, defence applications need the high secured communication over the channel.
Most of the defence-based communications are performed through the audio and speech …

Perfect reconstruction of wavelet filter banks helps in retrieving a hidden signal. In wavelet
domain different techniques are applied on the wavelet coefficients to increase the hiding …

A new method to secure speech communication using the discrete wavelet transforms
(DWT) and the fast Fourier transform is presented in this article. In the first phase of the …

In the last two decades, it has been observed that there have been remarkable
advancements in digital media communication. It has lots of advantages and business …

In this paper, we present a novel speech steganography method using discrete wavelet
transform and sparse decomposition to address the undetectability concern in speech …

The performance of audio steganography compression system using discrete wavelet
transform (DWT) is investigated. Audio steganography coding is the technology of …
