Detection of modern JPEG steganographic algorithms has traditionally relied on features
aware of the JPEG phase. In this paper, we port JPEG-phase awareness into the
architecture of a convolutional neural network to boost the detection accuracy of such
detectors. Another innovative concept introduced into the detector is the" catalyst kernel"
that, together with traditional high-pass filters used to pre-process images allows the network
to learn kernels more relevant for detection of stego signal introduced by JPEG …

Detection of modern JPEG steganographic algorithms has traditionally relied on features aware of the JPEG phase. In this paper, we port JPEG-phase awareness into the architecture of a convolutional neural network to boost the detection accuracy of such detectors. Another innovative concept introduced into the detector is the "catalyst kernel" that, together with traditional high-pass filters used to pre-process images allows the network to learn kernels more relevant for detection of stego signal introduced by JPEG steganography. Experiments with J-UNIWARD and UED-JC embedding algorithms are used to demonstrate the merit of the proposed design.
