Disappearing Cryptography, Second Edition describes how to take words, sounds, or images and hide them in digital data so they look like other words, sounds, or images. When used properly, this powerful technique makes it almost impossible to trace the author and the recipient of a message. Conversations can be submerged in the flow of information through the Internet so that no one can know if a conversation exists at all.
This full revision of the best-selling first edition describes a number of different techniques to hide information. These include encryption, making data incomprehensible; steganography, embedding information into video, audio, or graphics files; watermarking, hiding data in the noise of image or sound files; mimicry, “dressing up” data and making it appear to be other data, and more.
The second edition also includes an expanded discussion on hiding information with spread-spectrum algorithms, shuffling tricks, and synthetic worlds. Each chapter is divided into sections, first providing an introduction and high-level summary for those who want to understand the concepts without wading through technical explanations, and then presenting greater detail for those who want to write their own programs. To encourage exploration, the author's Web site
www.wayner.org/books/discrypt2/ contains implementations for hiding information in lists, sentences, and images.
“Disappearing Cryptography is a witty and entertaining look at the world of information hiding. Peter Wayner provides an intuitive perspective of the many techniques, applications, and research directions in the area of steganography. The sheer breadth of topics is outstanding and makes this book truly unique. A must read for those who would like to begin learning about information hiding.” --Deepa Kundur, University of Toronto
“An excellent introduction for private individuals, businesses, and governments who need to under- stand the complex technologies and their effects on protecting privacy, intellectual property and other interests.” - David Banisar, Research Fellow, Harvard Information Infrastructure Project, & Deputy Director, Privacy International.

● Do you have personal information in your database?
● Do you keep les on your customers, your employees, or anyone else?
● Do you need to worry about European laws restricting the information you keep?
● Do you keep copies of credit card numbers, social security numbers, or other informa- tion that might be useful to identity thieves or insurance fraudsters?
● Do you deal with medical records or personal secrets?
Most database administrators spend some of each day worrying about the information they keep. Some spend all of their time. Caring for information can be a dangerous responsibility.
This new book, Translucent Databases, describes a different attitude toward protecting the information. Most databases provide elaborate control mechanisms for letting the right people in to see the right records. These tools are well designed and thoroughly tested, but they can only provide so much support. If someone breaks into the operating system itself, all of the data on the hard disk is unveiled. If a clerk, a supervisor, or a system administrator decides to turn traitor, there's nothing anyone can do.
Translucent databases provide better, deeper protection by scrambling the data with encryption algorithms. The solutions use the minimal amount of encryption to ensure that the database is still functional. In the best applications, the personal and sensitive information is protected but the database still delivers the information.
