The rapid spread in digital data usage in many real life applications have urged new and
effective ways to ensure their security. Efficient secrecy can be achieved, at least in part, by …

Steganography has been proposed as a new alternative technique to enforce data security.
Lately, novel and versatile audio steganographic methods have been proposed. A perfect …

In this paper, we introduce an audio encryption scheme based on the cosine number
transform (CNT). The transform, which is defined over a finite field, is recursively applied to …

Many audio watermarking schemes divide the audio signal into several blocks such that part
of the watermark is embedded into each of them. One of the key issues in these block …

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 …

This paper proposes a novel high capacity robust audio watermarking algorithm by using
the high frequency band of the wavelet decomposition at which the human auditory system …

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, a robust and highly imperceptible audio watermarking technique is presented
based on discrete cosine transform (DCT) and singular value decomposition (SVD). The low …

In this paper, a non-blind digital audio watermarking algorithm that satisfies the minimum
requirements of optimal audio watermarking set by the International Federation of …
