نهانکاوی در تصاویر JPEG بر مبنای دستهبندی ویژگیهای آماری و تصمیمگیری دو مرحلهای
Abstract In this paper, we propose a comprehensive steganalysis scheme for JPEG images. In this method, the optimized features which can interpret high distinction between cover and stego images are extracted from images. These features have been selected after a careful study on modifications caused by different steganography algorithms on statistical characteristics of images. Furthermore, us...
متن کاملOn locating steganographic payload using residuals
Locating steganographic payload using Weighted Stego-image (WS) residuals has been proven successful provided a large number of stego images are available. In this paper, we revisit this topic with two goals. First, we argue that it is a promising approach to locate payload by showing that in the ideal scenario where the cover images are available, the expected number of stego images needed to ...
متن کاملSteganalysis of JPEG Images: Breaking the F5 Algorithm
In this paper, we present a steganalytic method that can reliably detect messages (and estimate their size) hidden in JPEG images using the steganographic algorithm F5. The key element of the method is estimation of the cover-image histogram from the stego-image. This is done by decompressing the stego-image, cropping it by four pixels in both directions to remove the quantization in the freque...
متن کاملInformation Hiding by Inverting the LSB bits of DCT Coefficients of JPEG images
Embedding messages bits in a cover-object affects the first order statistical properties of the cover-object. In this paper a new technique is introduced to hide information bits in the redundant bits of JPEG images with preserving the statistical properties. This technique proved to defeat the visual and statistical attacks and offer higher capacity than existing steganographic systems. [Hamdy...
متن کاملThe Best Transform in the Replacement Coefficients and the Size of the Payload Relationship Sense
Steganography is the hiding of payload data within cover data. The goal of a steganographic method is to minimize the visually apparent and statistical differences between the cover data and a steganogram while maximizing the size of the payload. Current digital image steganography presents the challenge of hiding data in a digital image in a way that is robust to image manipulation and attack....
