This is the third edition of my book that explores how to hide information where it isn't very obvious.

This new version includes new chapters:

• Synchronization -- How to find the beginning of a data stream.
• Obfuscation -- How to scramble code so its true meaning is hidden. This is a way that steganography can be quite useful in places where steganography is not usually found.
• Translucent Databases -- A short version of my book that describes how to build a database that does useful work without holding any useful information in it.
• Plain Sight -- There are a number of hidden corners in standard formats where information can be squirreled away.
