Abstract(in English) | We propose a new digital watermark method with the phase spectrum for digital music. Because, aural of human is hebetude to the change of the phase. And, it has been thought that the deterioration in music quality is reduced by "octave similarity". Moreover, we let frequency band change by PN (Pseudo Noise) sequence. Simulation results showed that proposed method has high secret and high tolerance against MP3(MPEG1 Audio Layer 3). Furthemore, we introduce band elimination filter (BEF) into the proposed method. The effectiveness of the procedure is shown for protecting embedded information against MP3. |
