In recent years, there has been considerable interest in the development of audio
watermarking techniques. To clarify the essential principles underlying a diversity of …

Audio watermarking is a technique providing a promising solution to copyrights protection
for digital audio and multimedia products. Using this technique, hidden information called …

Many effective watermarking algorithms have been proposed and implemented for digital
images and digital video, however, few algorithms have been proposed for audio …

This study presents a high‐performance audio watermarking scheme using spread
spectrum modulation. Unlike conventional extractors which use simple correlation, this …

A variable-dimensional vector modulation (VDVM) scheme is introduced to maximize the
efficiency of the norm-space DWT-based blind audio watermarking technique. This flexible …

Multimedia data play an important role in many areas such as business, medicine, and
entertainment. Multimedia contents are often vulnerable to malicious interventions due to the …

This paper introduces a method adjustable audio watermarking approach with high auditory
quality by exploiting the Spread Spectrum (SS) and the psychoacoustic modeling-based …

Motivated by the human auditory perception, a framework jointly exploiting the discrete
wavelet packet transform (DWPT) and the discrete cosine transform (DCT) is presented to …

Many previous (semi-) fragile audio watermarking schemes adopt binary images as
watermarks, which reduce the security of watermarking systems. On the other hand, the …

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 …
