Image-based steganography is an essential procedure with several practical applications
related to information security, user authentication, copyright protection, etc. However, most …

Conventional steganography methods fabricate the secret information into the cover pixels
without analyzing the pixel intensities of an image. As a result, some minor pixel level …

With the advent of internet, secured transmission of data over networks offers a great
challenge. This problem of secrecy of information has drawn a lot of attention due to its …

In this paper, we present a new adaptive contourlet-based steganography method that hides
secret data in a specific or automatically selected cover image. Our proposed …

In this paper, the authors have proposed an image steganography method for improving the
embedding capacity of the gray-scale cover image. In general, the embedding of the secret …

This paper introduces an edge-based image Steganography scheme in which the pixels of
the cover images are categorized into two classes: edge and non-edge. In general, the edge …

In steganography, secret data are invisible in cover media, such as text, audio, video and
image. Hence, attackers have no knowledge of the original message contained in the media …

To provide large capacity of the hidden secret data and to maintain a good visual quality of
stego-image a novel steganographic method based on neural network and random …

Abstract Information hiding is very important during the transmission, so that it cannot be
disclosed to unauthenticated persons. Steganography is one of the famous methods to hide …

Exchange of secret messages on the internet is a big issue for the researchers. This raises
the need of an information hiding technique, Steganography is an art of hiding digital …
