|Project Description: ||Steganography is the art of concealed communication. Steganography is derived from the Greek word “steganos”, which means hidden or secret and “graphy” means writing or drawing. Thus Steganography means secret writing. Steganography can be implemented in text, images, audio or video. The concealment of information is just not enough in some cases. The data should be encrypted and then hidden. Thus even if some one is able to recover the secret data from carrier file, the actual content is not revealed.
This technical report discusses a Stego tool which implements ‘Audio Steganography’ or ‘Wav Stego’ using a .wav file as carrier, the tool can embed any file in it, without altering the quality of the audio file used. The properties of the cover file still remains unchanged even after embedding any file into it.
This tool can be extended to other carrier file formats such as mp3, wma, wmv etc., and also the size of secret file to be hidden can be increased.
