AnApproach toDigital Watermarking ofSpeechSignals intheTime- Frequency Domain

A watermarking scheme inthetime-frequency domainisproposed. Theregion forwatermark embedding isselected byusingtheS-method based on thetime-frequency representation. Time-varying filter scheme isused tomap thewatermark sequencefromthetime-frequency domain tothetimedomain. Watermark detection isperformed inthetime-frequency domain. Theory isillustrated bytheexample.
