This book deals with how information can disappear so that no one knows of its existence. Convential cryptography merely scambles information into an impenetrable block. This book describes how data can be hidden in the background noise of pictures, sound recording or even bad poetry.Disappearing Cryptography is a collection of mathematical tricks and computational sleights of hand that explore the very foundations of information. Features: * Visual stenography * Covers textual cryptoanalysis * Discusses how to set up networks with hidden communications

From the Author

Plenty of Examples, More Code Available
I wrote this book to be a fairly accessable introduction to the science (and art) of hiding information. This is a crucial part of any security system.

As for the negative review from some fellow in Sacramento, I can only say that I'm sorry to have disappointed him. I don't think source code is a great use for paper. It's good to have a few examples, but there's no reason to put too much of it in. People read words but they peruse source code. It's better to have it on line.

If you don't like Pascal (which is more readable than C), then I'll email you C or Java. (You don't even need to buy the book.)

As for his comments about readability of the text that hides information, I think he's plain wrong. If he didn't like how the examples turned out, then he could have created his own grammar. The system is flexible enough to do that.

I hope other people will read the book for what it is instead of what they wish it could be. For those like the fellow from Sacramento who think the book could have been better, I hope that they'll sit down and write a better book. I'm looking forward to reading it.

3.0 out of 5 stars Interesting primer on the foundations of steganography, 23 Oct 1998

By A Customer

The book provides a basic foundation for the field of steganography. Steganography essentially conceals a message within another context as opposed to cryptography which conceals the content of the messages through mathematical manipulation.

Portions of the book are interesting and informative. For persons new to cryptography, this text will provide good food-for-thought. The concise descriptions of parity bits, bit math, and compression algorithms are very interesting.

The treatment of steganography is good but does not really go into implementation details. That is, the topic is discussed conceptually.

The book was published in 1996. The dated approach is starting to show in the text. In all, it is still an interesting read.

4.0 out of 5 stars Think Steganography rather than Cryptography., 2 Nov 1997

By A Customer

This book is about concealing the very existence of your messages where cryptography is about obscuring the content of them alone. The two are not quite the same thing, as you'll find out within.
