Picture quality and statistical undetectability are two key issues related to steganography
techniques. In this paper, we propose a closed-loop computing framework that iteratively …

Image steganography is the art of hiding information into a cover image. This paper presents
a novel technique for Image steganography based on Block-DCT, where DCT is used to …

In this paper, we propose a high capacity steganographic method using modulus function of
pixel-value differencing (PVD) and least significant bit (LSB) replacement methods. Many …

Steganography is a technique in which a person hides information in digital media. The
message sent by this technique is so secret that other people cannot even imagine the …

Image steganography is a technique for hiding the secret data in a carrier image. This paper
proposes a novel n-right most bit replacement image steganography technique to hide the …

The increase of data communication globally requires secure exchange of private
information. Steganography is a common form of information hiding from an unauthorized …

Image steganography is a technique of hiding secret data into a cover image and so as to
prevent the intruders from accessing the secret data. The efficiency of image steganography …

Main goal of steganography is to communicate securely in a completely undetectable
manner. It is an art of hiding secret data in an innocently looking dummy container. In the …

This article proposes a very high capacity steganography technique using differencing and
substitution mechanisms. It divides the image into non-overlapped 3 * 3 3× 3 pixel blocks …

In this paper, we shall propose a new image steganographic technique capable of
producing a secret-embedded image that is totally indistinguishable from the original image …
