Hiding in Plain Sight: Steganography and the Art of Covert Communication
Eric Cole, Ronald L. Krutz · 2003
From the Publisher: These days, encryption of confidential data and communications is an increasingly important part of doing business. But steganography can take data confidentiality to a whole new level, since it hides encrypted messages in ordinary-looking data files, making the very existence of the messages practically undetectable. Although steganography is not a new field and has played a critical part in secret communication throughout history, few people understand exactly how it works today. This detailed, practical guide changes that -- whether your goal is to add an extra level of security to business or government communications or to detect and counter steganography when it's used by criminals or terrorists.
