This work proposes a novel dual-channel time-spread echo method for audio watermarking,
aiming to improve robustness and perceptual quality. At the embedding stage, the host …

This paper presents a novel high-capacity audio watermarking system to embed data and
extract them in a bit-exact manner by changing some of the magnitudes of the FFT spectrum …

In this paper, we propose a semi-blind, imperceptible, and robust digital audio watermarking
algorithm. The proposed algorithm is based on cascading two well-known transforms: the …

Digital audio watermarking is very popular in recent research area, watermarking is a
method to hide information signal into digital form based on spread spectrum, The identity of …

The use of peer-to-peer (P2P) networks for multimedia distribution has spread out globally in
recent years. The mass popularity is primarily driven by efficient distribution of content, also …

This paper proposes a blind audio watermarking algorithm to embed data and extract them
by changing the Discrete Cosine Transform (DCT) coefficients. The key idea is to divide the …

In this paper, we present a unified algorithm for phase and magnitude speech spectra data
hiding. The phase and the magnitude speech spectra are concurrently investigated to …

This paper deals with a new digital audio watermarking scheme based on multiple access
techniques. In digital communication, multiple access techniques allow several users …

Multicast distribution of content is not suited to content-based electronic commerce because
all buyers obtain exactly the same copy of the content, in such a way that unlawful …

In this paper, we have combined watermarking and biometrics for possible improvement in
owner identification/verification technology. We have proposed and compared wavelet …
