Steganalysis of Degraded Document Images

2005 IEEE 7th Workshop on Multimedia Signal Processing, 2005
In this paper, a steganalysis technique using compression bit rate as a distinguishing statistic is presented to detect secret messages embedded in document images that are degraded in quality by printing, photocopying, and/or scanning processes. We consider embedding techniques that flip pixels in binary document images that contain characters and ...

Quantitative steganalysis of binary images

2004 International Conference on Image Processing, 2004. ICIP '04., 2005
We propose a quantitative steganalysis method to detect hidden information embedded by flipping pixels along boundaries in binary images. We model steganographic embedding as an additive noise process and use compression rate as a distinguishing statistic that aids in discriminating between stego-images and cover-images.

PSW statistical LSB image steganalysis

Multimedia Tools and Applications, 2017
Steganography is the art and science of producing covert communications by concealing secret messages in apparently innocent media, while steganalysis is the art and science of detecting the existence of these. This manuscript proposes a novel blind statistical steganalysis technique to detect Least Significant Bit (LSB) flipping image steganography ...

Steganalysis of Binary Text Images

Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006
We present in this paper a technique for the steganalysis of electronic text documents. The proposed method averages the similar patterns together in a binary text image to estimate the original patterns. The proposed method can detect the existence of a secret message hidden by any boundary flipping techniques as well as estimate the message length ...

Halftone Image Steganalysis by Reconstructing Grayscale Image

2021
Utilizing some special pixels patterns constructing the steganalytic features is popular in binary image steganalysis, which could be also used in halftone image. There is almost no specific image steganalysis for halftone image. In this paper, a halftone image steganalysis scheme is proposed and achieves a satisfactory performance, which is totally ...

Escaping difference image histogram steganalysis

Proceedings of the International Conference & Workshop on Emerging Trends in Technology - ICWET '11, 2011
Steganography is used to hide the occurrence of communication. Discovering and rendering useless such covert message is an art of Steganalysis. A popular Steganalysis technique is Difference Image Histogram (DIH), proposed by Zhang, aimed at LSB steganography. This algorithm can not only detect the existence of hidden messages embedded using sequential

Image steganalysis for digital forensics

2020
Στην σημερινή εποχή, η στεγανογραφία είναι ο κύριος τρόπος για την επίτευξη παράνομης μυστικής επικοινωνίας. Ως εκ τούτου, η ανάγκη ανίχνευσης στεγανογραφικού περιεχομένου και ιδίως στεγανογραφημένων εικόνων γίνεται επιτακτική. Ωστόσο, η στεγανάλυση είναι ένα πολύ δύσκολο έργο και η επιτυχία της εξαρτάται από πολλούς παράγοντες, όπως η παρουσία του ...

Metric learning for image steganalysis

2015 12th International Conference on Fuzzy Systems and Knowledge Discovery (FSKD), 2015
Image steganalysis based on supervised distance metric learning is to find an appropriate measure of similarity between image features where the distribution discrepancy between cover-images and stego-images are analyzed in the reduced dimensional space.

A novel approach for image steganalysis

Proceedings ELMAR-2014, 2014
Since JPEG images have been widely used in our daily life, the steganalysis for JPEG images becomes very important and significant. The Article addresses steganalysis in static images based on DCT transformed region, able to recognize the most popular steganography algorithms occurring on the Internet.

Image steganalysis with binary similarity measures

Proceedings. International Conference on Image Processing, 2003
We present a novel technique for steganalysis of images that have been subjected to least significant bit (LSB) type steganographic algorithms. The seventh and eighth bit planes in an image are used for the computation of several binary similarity measures.
