Digital audio, video, images, and documents are flying through cyberspace to their respective owners. Unfortunately, along the way, individuals may choose to intervene and take this content for themselves. Digital watermarking and steganography technology greatly reduces the instances of this by limiting or eliminating the ability of third parties to decipher the content that he has taken. The many techiniques of digital watermarking (embedding a code) and steganography (hiding information) continue to evolve as applications that necessitate them do the same. The authors of this second edition provide an update on the framework for applying these techniques that they provided researchers and professionals in the first well-received edition. Steganography and steganalysis (the art of detecting hidden information) have been added to a robust treatment of digital watermarking, as many in each field research and deal with the other. New material includes watermarking with side information, QIM, and dirty-paper codes. The revision and inclusion of new material by these influential authors has created a must-own book for anyone in this profession.

Ingemar J. Cox holds a B.Sc. from University College London and a Ph.D. from Oxford University. He worked at AT&T Bell Labs from 1984 until 1989 and in 1989 joined NEC Research Institute as a senior research scientist. From 1997 to 1999, he served as CTO of Signafy, an NEC subsidiary responsible for commercialization of watermarking, In 1999, he returned to the NEC Research Institute as a Research Fellow.
