J2: Refinement of a Topological Image Steganographic Method
نویسندگان
چکیده
Prior work described the baseline version J1 of a spatial domain image steganographic embedding based on manipulation of the frequency domain, and presented a topological approach to the problem. This paper modifies the embedding and extraction processes of J1 to allow for larger payload. The improved steganographic algorithm is called J2, and is more robust to steganographic detection than J1. J2 lends itself to probabilistic analysis (done elsewhere) due to the nature of the modifications to the embedding and extraction methods.

Steganalysis of embedding in difference of image pixel pairs by neural network
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 is di_erent as compared with a cover image. A number of characteristics are identified in the di...
متن کاملMorphological and Crystallographic Characterization of Nanoparticles by Granulometry Image Analysis and Rietveld Refinement Methods
The particle size distribution of the resultant cobalt ferrite samples was determined from Scanning Electron Microscopy (SEM) images using the granulometry image analysis method. Results showed the nanosized particles of the samples. The X-Ray Diffraction (XRD) patterns of samples were also analyzed by Rietveld refinement method. The results indicated that the precipitated sample at 95 <sup...

Steganography and steganalysis of digital images is a catand-mouse game. In recent work, Fridrich, Goljan and Du introduced a method that is surprisingly accurate at determining if bitmap images that originated as JPEG les have b en altered (and even specifying where and how they were altered), even if only a single bit has been changed. However, steganographic embeddings that encode embedded d...
متن کاملA High Quality Steganographic Method Using Morphing
A new morphed steganographic algorithm is proposed in this paper. Image security is a challenging problem these days. Steganography is a method of hiding secret data in cover media. The Least Significant Bit is a standard Steganographic method that has some limitations. The limitations are less capacity to hide data, poor stego image quality, and imperceptibility. The proposed algorithm focuses...
متن کاملStatistical Image Classification for Image Steganographic Techniques
Steganography is the method of information hiding. Free selection of cover image is a particular preponderance of steganography to other information hiding techniques. The performance of steganographic system can be improved by selecting the reasonable cover image. This article presents two level unsupervised image classification algorithm based on statistical characteristics of the image which...
