A Detailed look at Steganographic Techniques and their use in an Open-Systems Environment
This paper's focus is on a relatively new field of study in Information Technology known as Steganography. This paper will take an in-depth look at this technology by introducing the reader to various concepts of Steganography, a brief history of...
A Discussion of Covert Channels and Steganography
For those whose task it is to assure security, electronic communication without scrutiny that can continue between parties trying to circumvent a security policy poses a risk. This is true whether the "parties" are individuals with malicious ...
A Framework for Evaluating the Data-Hiding Capacity of Image Sources
An information-theoretic model for image watermarking and data hiding is presented in this paper. Recent theoretical results are used to characterize the fundametal capacity limits of the image watermarking and data-hiding systems. Capacity is determ...
A Joint Source-Channel Coding Scheme for Image-in-Image Data Hiding
We consider the problem of hiding images in images. In addition to the usual design constraints such as imperceptible host degradation and robustness in presence of variety of attacks, we impose the condition that the quality of the recovered signatu...
A Mathematical Approach to Steganalysis
A mathematical approach to steganalysis is presented in this paper with linear steganography being the main focus. A mathematically formal definition of steganalysis is given followed by definitions for passive and active steganalysis. The steganalys...
A Mathematical Framework for Active Steganalysis
A mathematical framework for steganalysis is presented in this paper with linear steganography being the main focus. A mathematically formal definition of steganalysis is given. Then, active steganalysis defined as the extraction of a hidden message ...
A Robust Data Hiding Technique using Multidimensional Lattices
This paper proposes a robust data hiding technique using channel codes derived from a finite subset of general n-dimensional lattices. In the proposed approach, a gray-scale image is embedded by perturbing the host wavelet coefficients.
A Technique for Image Data Hiding and Reconstruction without Host Image
This paper addresses specifically the problem of image data hiding and recovery in the absence of host image data. Compared to related work, the proposed technique can embed significantly larger amount of signature data into the host - upto 25% of th...
Active Steganalysis of Sequential Steganography
Steganalysis of sequential steganography is presented in this paper. Abrupt change in statistics due to sequential embedding is exploited by the proposed technique. Analytical derivations are presented for several cases along with experimental result...
Adaptive Steganography with AES
This software implements an adaptive steganography algorithm called Adaptive Minimum Error Least Significant Bit Replacement(AMELSBR) along with AES 128, 192 and 256 bit cipher for 24-bit bitmap files.
