MP3 robust Audio Watermarking

This paper presents methods for audio watermarking in the frequency domain. It will consider desired properties and possible applications of watermark ing algorithms. Special attention is given to statistical methods relying on the so-called patch work techniques. It will present a solution of robust watermarking of audio data and reflect the security properties of the technique. Experimental results show good robustness of the approach against MP3 compression and other common signal processing manipulations. Enhancements of the presented methods are discussed.
