Analysis of Various Image Steganography Techniques Based Upon PSNR Metric
Every common person uses internet directly or indirectly in some spheres of his life. They mainly use the internet for information sharing. Also, information sharing has the primary importance in the field of Military Services, Medical Services, Mobile Services, and Investigation Agencies etc. The main hurdle in the path of information sharing is the security of information. The information sec...
متن کاملImage Based Steganography Methods With High Payload
There is a lot of research going on to find a stenography technique which is not only imperceptible but also has other two features, namely, high embedding capacity and robustness. Imperceptibility is the most important requirement of steganography followed by high capacity. In this paper we give an overview of high capacity image steganographic techniques and propose a novel imperceptible and ...
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 کاملPalette-Based Image Steganography for High-Capacity Embedding
We propose an efficient steganographic scheme for palette-based images that improves the maximum length of the embedded message and does not seriously degrade the image quality in this paper. The proposed scheme embeds a multiple-bit message within the units of a 2 × 2 pixel matrix by assigning a parity to each pixel matrix according to the Euclidean distance. The stegoimages created by using o...
