Steganalysis of the MELP quantization index modulation data hiding methods by using chaotic type features

The success of data hiding methods, which hide data to media like speech signal, is primarily determined by their strength aganist to the steganalysis methods. In this paper, some data hiding methods, which embed secret data during MELP analysis of speech signal using quantization index modulation are introduced. These methods in question are examined by a steganalysis method which takes advantage of chaotic-type features of speech signal. Thus, by evaluating the steganalysis results, the practical usage limitations of data hiding methods can be exposed.
