Abstract:
Digital Watermarking has been proposed as a
mean to identify the owner or distributor of digital
data. It involves the concealment of data within a
discrete audio file. Audio Watermarking has been
proposed as a possible solution, embeds copyright
information into audio files as a proof of their
ownership. In this paper, we propose an effective,
robust and inaudible Audio Watermarking algorithm.
Audio Watermarking scheme has been carried out
where a visually recognizable binary image is used
as a watermark. The effectiveness of the algorithm is
brought by applying a cascade of two powerful
mathematical transforms: the discrete wavelet
transform (DWT) and the singular value
decomposition (SVD). In the proposed algorithm,
watermark bits are not embedded directly into
DWT’s coefficient, but rather on the elements of
singular values of the DWT sub-bands of the audio
frames. This system is implemented using MATLAB
programming language and validated through a set
of music records. Experimental results are presented
in this paper to demonstrate the effectiveness of the
proposed algorithm.
