In this paper we propose a new scheme for blind watermarking of speech and audio signals.
We used the discrete wavelet transform (DWT) after framing the signal, and then we applied …

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 …

Abstract International Federation of Phonographic Industry (IFPI) has laid requirements for
digital audio watermarking (DAW) schemes with regard to robustness, imperceptibility and …

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 cost-effective distribution of content …

In this paper, we present a novel scheme for enhancing the security of speech information in
communication systems. We build a hybridization of three approaches: Chaotic logistic and …

Steganography is a popular technique of digital data security. Among all digital
steganography methods, audio steganography is very delicate as human auditory system is …

This paper proposes an effective multiple watermarking algorithm based on Discrete
Wavelet Transform for audio signal. This approach embeds multiple gray images inside the …

Audio watermarking is used as a tool to avoid the illegal manipulation of audio products. In
this research, we proposed the audio watermarking system with adaptive BCH code …

This study proposes audio watermarking scheme based on Arnold transform with discrete
wavelet transform (DWT) singular value decomposition (SVD) methods. The value on of bit …

It is always necessary to protect copyrights of multi-media data in order to prevent misuse
and to reduce the loss caused by piracy. So, it is necessary to find methods for copyright …
