The basic spread spectrum (SS) method attempts to spread secret information across the frequency spectrum of the audio signal. This system is similar to a system which uses an implementation of the LSB that spreads the message bits randomly over the entire sound file. Unlike LSB coding, the Spread Spectrum method spreads the secret information over the …

SPREAD SPECTRUM TECHNIQUE Spread Spectrum steganography on audio data will be implemented with the following scheme: Transform the audio cover object in time-domain into frequency- domain using Fast Fourier Transform. Adding the information signal by using spread-spectrum to the cover object in frequency-domain. Transform back the audio cover …

steganography Image steganography Audio steganography- Audio steganography requires a. text or audio secret message to be embedded within a cover audio message. Due to availability of redundancy, the cover audio message before steganography and the stego message after steganography remains the same.

Audio Steganography methods can embed any messages in WAV, and even MP3 sound files. In Audio Steganography system, secret messages are embedded into digitized audio signal which results into altering binary sequence of corresponding audio files. Audio steganography techniques are lesser prone to malicious

information even exists. If a steganography method causes someone to suspect there is a secret information in a carrier medium, then the method has failed [6,8]. The basic model of Audio steganography consists of Carrier (Audio file), Message and Password. Carrier is also known as a cover-file, which conceals the secret information.

Steganographic techniques:Audio, Phase Encoding . Encodes message as phase shifts in the phase spectrum of a digital signal. Relies on the fact that phase components of sound are not as perceptible as noise is. Steps: Break signal into smaller segments. Discrete Fourier Transform (DFT) Phase diff. between adjacent segments
