Abstract

This paper presents audio watermarking process which embeds binary grey scale image as a watermark signal into sound signal. A (segments) patchwork-based audio watermarking method is used for insertion of watermark bits. Average of all segments of approximate coefficients, is calculated for embedding watermark picture pixels into sound signal. The experimental results show that proposed method achieves moderate payload for the security of audio signal as we are using image, imperceptibility for audio signal as watermarked audio signal distortion is inaudible after embedding watermark and robustness of watermark against different signal processing attacks with PSNR greater than 20dB.
