A Blind Frequency Based Scheme For Audio Sounds Watermarking



Authors : Salah Euschi . Amine Khaldi . Redouane Kafi .

Abstract

In order to enhance the security of data exchanged in telemedicine, we propose in this work a blind watermarking scheme for audio sounds protection. A blind watermark method is proposed; the successful watermark integration will be typically done by combining three successive values parity; each variant will adequately represent a different combination. These approaches will be implemented in the frequency domain. The watermark bits will be substituted to the Discrete Cosine Transform coefficient’s least significant bit. The obtained results sufficiently demonstrate that our proposed approach offers a good imperceptibility results. However, using small audio file for our experiments significantly reduces the capacity of our used methods in the frequency domain.
