Abstract :
Image steganography has widely developed. There are also many algorithm developed for it. Meanwhile, the interest in using audio data as cover object in steganography can be spelled out late emergence than image data. This paper discusses the implementation of steganography in audio data using Direct Sequence Spread Spectrum method. Spread Spectrum method is often used to send hidden message through radio waves. This message is transmitted through noise-like wave. The same method can be applied to embed message in audio data. The embedded audio data will be heard as noise. The Spread Spectrum method used in this paper is Direct Sequence Spread Spectrum. A key is needed to embed messages into noise, this key is used to generate pseudo-noise wave. The information to be embedded must first modulated using the pseudo-noise. This paper discusses implementation of the method in audio data to hide text message. Spread Spectrum method is known to be very robust, but as a consequence the cost is very large, the implementation is relatively complex, and the information capacity is very limited. This problem will also be discussed in this paper.
