BOOK DESCRIPTION:

"Information Hiding: Steganography and Watermarking - Attacks and Countermeasures presents important research contributions in three fundamental areas: investigation of data hiding and labeling techniques (steganography and watermarking), attacks against steganography and watermarked information, and countermeasures to such attacks. With the proliferation of multimedia and concerns of privacy on the Internet, such research has become even more pressing. Information is collected by numerous organizations and the nature of digital media allows for the exact duplication of material with no notification that the material has been copied. The more information placed in the public's reach on the Internet, the more owners of such information need to protect themselves from unwanted surveillance, theft, and false representation and reproduction. Systems to analyze techniques for uncovering hidden information and recovering seemingly destroyed information are thus of great importance to many groups, including law enforcement authorities in computer forensics and digital traffic analysis." "Techniques for hiding information have existed for centuries. Methods include communication via invisible inks, microdots, covert channels, and spread spectrum channels. The techniques explored by the authors involved embedding information within digital media, specifically digital images. The authors analyze the limitations of these digital methods, which can in turn be used to devise attacks. The goal of these attacks is to expose the existence of a secret message or to render a digital watermark unusable. Finally, in assessing these attacks, countermeasures are developed to assist in protecting digital watermarking systems. Understanding the limitations of these methods will allow the construction of more robust methods that can better survive manipulations and attacks."
