Seppanen, Makela and Keskinarkaus (SMK) have proposed a high-capacity steganographic
technique to conceal information within a colour image. The technique is significant because …

Steganography is the art of hiding the fact that communication is taking place, by hiding
information in other information. Security has always been a major concern since time …

In this paper, we present a steganographic method for embedding a color or a grayscale
image in a true color image. Three types of secret images can be carried by the proposed …

Using the least significant bits in an image, in this paper we propose two new techniques
that use truth table based and determinate array on RGB indicator that utilizes the idea of …

To improve the embedding capacity and provide an imperceptible visual quality, a novel
steganographic method based on four-pixel differencing and modified least significant bit …

Significant bit) based Steganography technique for images imparting better information
security. It presents an embedding algorithm for hiding encrypted messages in nonadjacent …

In traditional steganographic schemes, RGB three channels payloads are assigned equally
in a true color image. In fact, the security of color image steganography relates not only to …

This paper proposes an image steganography technique based on the principle of pixel
overlapping to improve the embedding capacity (EC) and peak signal-to-noise ratio (PSNR) …

Embedding a secret message into the pixels of a cover image yields a visual distortion if
these pixels belong to smooth regions. Thus, this prompted the development of some edge …

In order to provide large embedding capacity and to minimize distortion for the stego-image,
a steganographic method using multi-pixel differencing is presented in this paper. We …
