A NEW APPROACH FOR SPEECH AUDIO STEGANALYSIS USING DELAY VECTOR VARIANCE METHOD
Abstract :
We investigate the use of delay vector variance-based features for recorded speech steganalysis. Considering that data hiding within a speech signal distorts the properties of the original speech signal, we design a steganalyzer that uses surrogate data based delay vector variance (DVV) features to detect the existence of a stego-signal. We evaluate the performance of the proposed DVV features as steganalyzer with numerical results.
