Data Hiding: Other Methods

Abstract

Starting with Section 12.2, this chapter discusses data hiding in an MPEG-2 video file. This is followed with audio steganography. Starting with Section 12.3, the basics of digital audio and the properties of the human auditory system are described, following with audio steganography in the time domain. Next, the chapter introduces (in Section 12.7) the concept of the steganographic file system. The last part of the chapter is a short discussion of the limits of steganography (Section 12.8) and the prospect of public-key steganography (Section 12.9).
