Abstract

A sort of audio watermarking algorithm in discrete cosine transform (DCT) domain can embed secret information through modification of the distinction between positive and negative direct current (DC) coefficients. Such an algorithm achieves a good balance between robustness and imperceptibility. This paper points out that steganographic methods change statistical characteristics of DC coefficients. It also states that the difference between positive and negative DC coefficients can detect whether an audio has hidden information or not. Experiment results justify that the algorithm accuracy is 79%.

Key words： steganography; steganalysis; audio; discrete cosine transform (DCT)
