Principles of Modern Steganography and Steganalysis

چکیده
The first work on digital steganography was published in 1983 by cryptographer Gustavus Simmons [217], who formulated the problem of steganographic communication in an illustrative example that is now known as the prisoners’ problem. Two prisoners want to cook up an escape plan together. They may communicate with each other, but all their communication is monitored by a warden. As soon as the warden gets to know about an escape plan, or any kind of scrambled communication in which he suspects one, he would put them into solitary confinement. Therefore, the inmates must find some way of hiding their secret messages in inconspicuous cover text.

Challenging the doctrines of JPEG steganography
The design of both steganography and steganalysis methods for digital images heavily relies on empirically justified principles. In steganography, the domain in which the embedding changes are executed is usually the preferred domain in which to measure the statistical impact of embedding (to construct the distortion function). Another principle almost exclusively used in steganalysis states th...
متن کاملDetection of perturbed quantization (PQ) steganography based on empirical matrix
Perturbed Quantization (PQ) steganography scheme is almost undetectable with the current steganalysis methods. We present a new steganalysis method for detection of this data hiding algorithm. We show that the PQ method distorts the dependencies of DCT coefficient values; especially changes much lower than significant bit planes. For steganalysis of PQ, we propose features extraction from the e...
