This book introduces audio watermarking methods for copyright protection  which has drawn
extensive attention for securing digital data from unauthorized copying. The book is divided
into two parts. First  an audio watermarking method in discrete wavelet transform (DWT) and
discrete cosine transform (DCT) domains using singular value decomposition (SVD) and
quantization is introduced. This method is robust against various attacks and provides good
imperceptible watermarked sounds. Then  an audio watermarking method in fast Fourier transform
(FFT) domain using SVD and Cartesian-polar transformation (CPT) is presented. This method has
high imperceptibility and high data payload and it provides good robustness against various
attacks. These techniques allow media owners to protect copyright and to show authenticity and
ownership of their material in a variety of applications. · Features new methods of audio
watermarking for copyright protection and ownership protection · Outlines techniques that
provide superior performance in terms of imperceptibility  robustness  and data payload ·
Includes applications such as data authentication  data indexing  broadcast monitoring 
fingerprinting  etc.
