This paper proposes an improved method of spline interpolation-based watermarking with increased robustness. The following convention will be followed throughout the paper. Let x be the original audio signal, w be the watermark and y = x + w be the watermarked audio. Let m be the embedded message, and m ^ be the estimate of the message after …

An audio watermarking scheme in wavelet domain which takes advantage of substitution is proposed in this paper. First the host audio is decomposed by wavelet transform, and then convert low frequency coefficients to segments. Finally embed the watermark XOR with a pseudo-random sequence into the host audio by substitution of the segments.

We performed watermarking under spatial domain watermarking technique. We followed INSTANT BIT SUBSTITUTION method to perform watermarking. For encoding part we changed the second last significant bit of host image whose pixel value is greater than 200, with that of the watermark image.Thus, we get our Watermarked image.

Abstract: An audio watermarking technique in the frequency do-main which takes advantage of interpolation is proposed. Interpolated FFT samples are used to generate imperceptible marks. The experi-mental results show that the suggested method has very high capacity (about 3kbps), without significant perceptual distortion (ODG about −0.
