Steganalysis of JSteg algorithm using hypothesis testing theory
This paper investigates the statistical detection of JSteg steganography. The approach is based on a statistical model of discrete cosine transformation (DCT) coefficients challenging the usual assumption that among a subband all the coefficients are independent and identically distributed (i. i. d. ). The hidden information-detection problem is cast in the framework of hypothesis testing theor...
متن کاملJSteg: Steganography and Steganalysis
1.Introduction: Steganography is the art and science of hiding communication; a steganographic system thus embeds hidden content in unremarkable cover media so as not to arouse an eavesdropper’s suspicion. In the past, people used hidden tattoos or invisible ink to convey steganographic content. Today, computer and network technologies provide easy-to-use communication channels for steganograph...
متن کاملLINEAR HYPOTHESIS TESTING USING DLR METRIC
Several practical problems of hypotheses testing can be under a general linear model analysis of variance which would be examined. In analysis of variance, when the response random variable Y , has linear relationship with several random variables X, another important model as analysis of covariance can be used. In this paper, assuming that Y is fuzzy and using DLR metric, a method for testing ...
متن کاملOn the Performance of Wavelet Decomposition Steganalysis with JSteg Steganography
In this paper, we study the wavelet decomposition based steganalysis technique due to Lyu and Farid. Specifically we focus on its performance with JSteg steganograpy. It has been claimed that the LyuFarid technique can defeat JSteg; we confirm this using different images for the training and test sets of the SVM classifier. We also show that the technique heavily depends on the characteristics ...
متن کاملA Novel Quantity Based on Clipping Statistics for Jsteg Steganalysis
Steganalysis is the art of detecting covert communication and has become an important research field, in which some of steganographic tools provide the function of embedding secret messages into JPEG images. To detect JPEG stego-images, we will identify a novel statistical quantity in this paper. In general, the JPEG decompression process performs color clipping in lots of pixels, and thus, mes...
