Abstract

Abstract: Steganography is the science and art of hiding secret messages in such a way so that the existence of messages is undetected by human senses. In this paper, multiple MP3 files are used as cover with the aim of increasing steganographic capacity without limiting the number of used files. Concealing secret messages in the form of files on the MP3 file cover can be performed by using homogenous frame. Homogeneous frames in the MP3 files store the bits of the inserted secret files. Before being inserted into some MP3 cover files, secret files are first encrypted employing AES algorithm with passwords implicated by MD5 processes. Audio quality changes between steganography MP3 files and original MP3 files are measured by using stereo signal strength and Mean Opinion Score (MOS). The test results show that the distribution of steganography load on multiple MP3 files can fulfill the user's needs for the capacity of steganography without reducing the quality of used MP3 files. This paper proposed a method about the increase of steganography capacity which is capable to insert and retrieve secret files on multiple MP3 audio files using homogenous frame utilization methods without resizing and reducing the quality of used MP3 files.
