Exactly Reversible Method of Data Embedding into an Audio File with Preservation of the Container Histogram

摘要

This paper presents a method for embedding data in an audio file container. A feature of this method is its resistance to attacks based on a comparison of histograms. The advantages of this method are its exact reversibility and the possibility of performance in real-time. The cost for these benefits is an increase in the amount of data two times and the emergence of high-frequency components in the stego audio file com- pared to the blank. This paper also presents the results of simulation algorithms of the method and the eval- uation of the relative capacity of the container. This method can also be used in the problem of watermark embedding in audio files.
