Transfer of multimedia content over untrusted public networks is
gaining popularity in recent years. Security of the multimedia
content is a major problem. Watermarking the multimedia content is
one viable solution to this problem. In this book, performance
evaluation of various watermarking algorithms available in the
literature is presented.The book presents three robust image
watermarking algorithms using Singular Value Decomposition (SVD),
catering to various needs of watermarking. Two robust watermarking
algorithms using Contourlet transform and Discrete Cosine Transform
(DCT) are proposed. Advantages of spatial and transform domains are
obtained by proposing a hybrid image watermarking algorithm.
Robustness of the proposed algorithms is tested for variety of
attacks. Comparative performance analysis of available and proposed
image watermarking algorithms should provide a basis for the
researchers working in the field of image watermarking. The book
should be useful for students, researchers, and others who want to
understand the significance of watermarking in multimedia
protection
