This book intends to provide a comprehensive overview on different aspects of mechanisms and techniques for information security.
It is written for students, researchers, and professionals studying in the field of multimedia security and steganography.
Multimedia security and steganography is especially relevant due to the global scale of digital multimedia and the rapid growth
of the Internet. Digital watermarking technology can be used to guarantee authenticity and can be applied as proof that the
content has not been altered since insertion. Updated techniques and advances in watermarking are explored in this new edition.
The combinational spatial and frequency domains watermarking technique provides a new concept of enlarging the embedding capacity
of watermarks. The genetic algorithm (GA) based watermarking technique solves the rounding error problem and provide an efficient
embedding approach. Each chapter provides the reader with a fundamental, theoretical framework, while developing the extensive
advanced techniques and considering the essential principles of the digital watermarking and steganographic systems. Several
robust algorithms that are presented throughout illustrate the framework and provide assistance and tools in understanding
and implementing the fundamental principles.
