Research of Methods of Steganographic Protection of Audio Information Based on Video Containers

Abstract

The chapter describes investigations of steganographic methods of information protection, which use containers represented by files in AVI format. MP3 audio files are selected as data that is embedded in the used container. For the introduction of audio data, the video container was divided into control and information parts. Secret data were embedded in the information part of the video file, which did not lead to distortions when the container file is played. Studies have been conducted to find repetitive blocks in the structure of a video container. The chapter analyzed the determination of the amount of embedded data for containers with different parameters: color saturation, video file resolution, video file length, compression quality, and frames per second. An algorithm has been developed for the introduction and extraction of information represented by sound formats.
