Query: Universal Audio Steganalysis Based on Calibration and Reversed Frequency
  Resolution of Human Auditory System   Calibration and higher order statistics (HOS) are standard components of many
image steganalysis systems. These techniques have not yet found adequate
attention in audio steganalysis context. Specifically, most of current works
are either non-calibrated or only based on noise removal approach. This paper
aims to fill these gaps by proposing a new set of calibrated features based on
re-embedding technique. Additionally, we show that least significant bit (LSB)
is the most sensitive bit-plane to data hiding algorithms and therefore it can
be employed as a universal embedding method. Furthermore, the proposed features
are based on a model that has the maximum deviation from human auditory system
(HAS), and therefore are more suitable for the purpose of steganalysis.
Performance of the proposed method is evaluated on a wide range of data hiding
algorithms in both targeted and universal paradigms. Simulation results show
that the proposed method can detect the finest traces of data hiding algorithms
and in very low embedding rates. The system detects steghide at capacity of
0.06 bit per symbol (BPS) with sensitivity of 98.6% (music) and 78.5% (speech).
These figures are respectively 7.1% and 27.5% higher than state-of-the-art
results based on RMFCC.
