- Abstract
Spread Spectrum Audio Watermarking (SSAW) technique based on Signal to Noise Ratio (SNR) is implemented in wavelet-DCT domain. The technique is developed for blind detection of watermark. To check the robustness of the technique, the watermarked signal is passed through different signal processing attacks .It is observed that the watermark remains present after all signal processing attacks. The technique is also tested with the subjective listening test and it is confirmed that there is no perceptible difference between the watermarked signal and the original host audio signal.
