We have developed a fast and reliable algorithm for audio steganography. Proposed method is capable to embed a secret message into a sound file.
Cover sound is modified and hidden message is made imperceptible. Our steganography algorithm results extremely robust to:
- Random white noise
- MPEG compression
- Random cropping
- Resampling
- Many other common sound processing algorithms
Index Terms: Matlab, source, code, speech, audio, encryption, system, steganography, hidden, message.
