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...
