Samenvatting:

Offers students and researchers with mechanical information regarding digital watermarking and steganography. This work provides them with the framework needed to develop advanced algorithms. It shows how robust high-capacity watermarking techniques can be used to enlarge the hiding capacity while maintaining the robustness of the watermark.

Every day millions of people capture, store, transmit, and manipulate digital data. Unfortunately free access digital multimedia communication also provides virtually unprecedented opportunities to pirate copyrighted material. Providing the theoretical background needed to develop and implement advanced techniques and algorithms, Digital Watermarking and Steganography:

• Demonstrates how to develop and implement methods to guarantee the authenticity of digital media
• Explains the categorization of digital watermarking techniques based on characteristics as well as applications
• Presents cutting-edge techniques such as the GA-based breaking algorithm on the frequency-domain steganalytic system

The popularity of digital media continues to soar. The theoretical foundation presented within this valuable reference will facilitate the creation on new techniques and algorithms to combat present and potential threats against information security.
