Abstract
Interpolation of a sample set from a signal gives a close mathematical, and hence, a perceptually similar approximation to the original samples. In this paper, an audio watermarking technique in the temporal domain using spline interpolation is proposed. Test results for imperceptibility of the watermark and its robustness against MP3 compression and resampling attacks are presented. The simulation study shows that the watermark performance is satisfactory against the two forms of attacks mentioned above. © 2008 Elsevier B.V. All rights reserved.
