This book introduces audio watermarking methods in transform domain based on matrix
decomposition for copyright protection. Chapter 1 discusses the application and properties of
digital watermarking. Chapter 2 proposes a blind lifting wavelet transform (LWT) based
watermarking method using fast Walsh Hadamard transform (FWHT) and singular value decomposition
(SVD) for audio copyright protection. Chapter 3 presents a blind audio watermarking method
based on LWT and QR decomposition (QRD) for audio copyright protection. Chapter 4 introduces an
audio watermarking algorithm based on FWHT and LU decomposition (LUD). Chapter 5 proposes an
audio watermarking method based on LWT and Schur decomposition (SD). Chapter 6 explains in
details on the challenges and future trends of audio watermarking in various application areas.
Introduces audio watermarking methods for copyright protection and ownership protection
Describes watermarking methods with encryption and decryption that provide excellent
performance in terms of imperceptibility robustness and data payload Discusses in details on
the challenges and future research direction of audio watermarking in various application
areas.
