Abstract

Many digital files are shared nowadays through internet especially due to the increase in the number of cell phone users. However, digital files can be easily copied, distributed, and altered leading to the copyright infringement of intellectual property. One way to prevent this is by using watermarking technique. The file in which watermark is embedded can be audio, image, text or video file. In this paper watermarking on audio file is done. The audio watermarking algorithm using fast Fourier transform is studied here. The watermarking system consists of two main steps watermark embedding and watermark extraction system. The technique used here is to put the watermark into the selected prominent peaks of the magnitude spectrum of the audio signal. The reason of hiding the watermark in this position is that it will be imperceptible for the human auditory system. The algorithm is also implemented on Beagle board hardware for online operation.
