Medical images may contain sensitive information and additional security measures are
essential to preserve the patient's privacy. The multiple watermarking is projected to …

In this paper different digital audio watermarking techniques have been proposed. Currently,
more attention is given to combination of Discrete Wavelet Transform (DWT) and Singular …

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

Due to the rapid development of sensor technology and the popularity of the Internet, not
only has the amount of digital information transmission skyrocketed, but also its acquisition …

The watermark embedded by traditional methods is easy to be lost under some attacks. To
overcome this problem, this study proposes a novel method based on DWT. It adopts a …

Imperceptible, robust, and embedding capacity are three main requirements for the
steganography of digital audio signal. To enhance them, this study presents a novel …

The main goal of this paper is to embed a watermark in the speech signal, using the three
techniques such as Discrete Cosine Transform (DCT) along with Singular Value …

In this work, a combination between Discrete Wavelet (DWT) and Discrete Cosine
Transforms (DCT) is used to watermark a digital human speech sequence. This novel …

The internet is a host for billions of pirated audio files, including songs, audio books,
podcasts, and voice recordings. People who illegally upload audio files on the internet …

The protection of the multimedia data is one of the main issue in the global village. Several
procedures are implemented to protect the digital data. Watermarking provide the robust …
