Audio file steganalysis through artificial neural networks
Ali̇ Durdu, Ahmet Turan Özcerit, Hayrettin Evirgen · 2011
In this study, we have developed a new steganalysis method that combines both Chi-square and PNN techniques. We have tested our steganalysis method on digital audio files. The stego files under test have been assumed to contain a secret data file embedded by a known steganography method, which is LSB (Least Significant Bit) steganography in our test environment. The method we have developed first analyzes the LSB bits in cover audio files then obtained intermediate data are applied to PNN to achieve more realistic results. While most steganalysis methods focuses on only detection of secret data, our method can also determine the rate of secret data.
