Opis

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
