Abstract :
This paper proposes a novel chaotic watermarking scheme for MP3 encoded audio signals. MP3 standard encodes audio signals in frequency domain and performs audio compression task by employing the psychoacoustic model of the audio signals. Spread spectrum chaotic signal that represents the copyright of the audio is embedded in the audio signal in the process of conducting MP3 encoding in which psychoacoustic model is used to control the perceptual distortion caused by both MP3 compression and chaotic watermarking.
