Standard cryptography locks information in a mathematical safe and many governments, corporations, and citizens of the Net are quickly embracing it to protect their privacy. But traditional algorithms like DES won't protect you against an active attack that jams a transmission, diverts an e-mail message, or erases some files. The disappearing cryptography (a.k.a. steganography) in this book is the solution. The algorithms show how to make information invisible. If you don't know it's there, you can't find it. Each chapter in the book is divided into three sections. The first approaches the topic with humor, the second offers a general introduction, and the third provides a complete technical solution. Topics covered include: - Hiding information in photographs - Disguising data as innocent text - Anonymous remailers - Completely Secure Transfer
