1. Optimizing image steganography by combining the GA and ICA

F. Sadeghi; F. Zarisfi Kermani; M. Kuchaki Rafsanjani

Volume 7, Issue 1 , Winter and Spring 2015, , Pages 47-58


  In this study, a novel approach which uses combination of steganography and cryptography for hiding information into digital images as host media is proposed. In the process, secret data is first encrypted using the mono-alphabetic substitution cipher method and then the encrypted secret data is embedded ...  Read More

2. Detection of perturbed quantization (PQ) steganography based on empirical matrix

M. Abolghasemi; H. Aghaeinia; K. Faez

Volume 2, Issue 2 , Summer and Autumn 2010, , Pages 119-128


  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 ...  Read More

3. Steganalysis of embedding in difference of image pixel pairs by neural network

V. Sabeti; Sh. Samavi; M. Mahdavi; Sh. Shirani

Volume 1, Issue 1 , Winter and Spring 2009, , Pages 17-26


  In this paper a steganalysis method is proposed for pixel value differencing method. This steganographic method, which has been immune against conventional attacks, performs the embedding in the difference of the values of pixel pairs. Therefore, the histogram of the differences of an embedded image ...  Read More
