Abstract :
In this paper, the application of the sinusoidal model for audio/speech signals to the watermarking task is proposed. The basic idea is that adequate modulation of medium rank partials (frequency) trajectories is not perceptible and thus this modulation may contain the data to be embedded in the signal. The modulation (encoding) and estimation (decoding) of the message are described and preliminary promising results are given in the case of speech signals.
