Modulo based Image Steganography Technique against Statistical and Histogram Analysis
Steganography is the art and science of communicating secret data by embedding it into a multimedia carrier. The ultimate goal here is to conceal the very existence of the embedded data. Although the term Steganography has been known for thousands of years, its digital version came about only lately and research was intensified after the depressing event of Twin towers (11th Sep 2001). Steganal...
متن کاملLocation-Based Image Steganography
The objective of steganography is to conceal the presence of a secret communication. Nevertheless, with the development of steganalytic attack, also known as steganalysis, there are many statistical methods to estimate the presence and ratio of secret messages. The chi square (χ 2 ) attack and regular-singular (RS) attack are two well recognized and widely applied statistical steganalysis schem...
متن کاملEdge-based image steganography
This paper proposes a novel steganography technique, where edges in the cover image have been used to embed messages. Amount of data to be embedded plays an important role on the selection of edges, i.e., the more the amount of data to be embedded, larger the use of weaker edges for embedding. Experimental results have shown that the proposed technique performs better or at least at par with th...
متن کاملHistogram-Based Image Segmentation
Histogram-based image segmentation is one of the simplest and most often used segmentation techniques. It uses the histogram to select the gray levels for grouping pixels into regions. In a simple image there are two entities: the background and the object. The background is generally one gray level and occupies most of the image. Therefore, its gray level is a large peak in the histogram. The ...
متن کاملSteganography with Least Histogram Abnormality
A novel steganographic scheme is proposed which avoids asymmetry inherent in conventional LSB embedding techniques so that abnormality in the image histogram is kept minimum. The proposed technique is capable of resisting the χ test and RS analysis, as well as a new steganalytic method named GPC analysis as introduced in this paper. In the described steganographic technique, a pair of mutually ...
