TITLE: A New Proposal to Insert Watermark into Audio Files Using the Hermite Transform

KEYWORDS: Audio, Hermite transform, imperceptible, recovered watermarking, watermarking.

ABSTRACT: In this work we present a new watermarking technique to audio files using the Hermite transform (HT). The main feature of this technique is that watermark can be recovered after it has been embedded and is not required the original file, such that it has a blind recovery technique. The use of HT with audio files is to determinate your performance with them, because the Hermite transform background is with digital images. However according to the results, we obtain an efficiently method to watermark audio files, achieving that the watermark is imperceptible to the human ear. In addition the results of metrics calculation, correlation and peak signal to noise ratio strengthen the effectiveness of the method. The file that is used as watermark is also an audio file, and the amount of information of the audio file is used as a watermark is half the length of the host audio.
