In order to improve the capacity of the hidden secret data and to provide an imperceptible
stego-image quality, a novel steganographic method based on least-significant-bit (LSB) …

Image based steganography utilize the images as cover media to hide secret data. The
common technique used in this field replaces the least significant bits (LSB) of image pixels …

Several problems arise among the existing LSB-based image steganographic schemes due
to distortion in a stegoimage and limited payload capacity. Thus, a proposed scheme has …

In this paper, we describe a novel spatial domain method for steganography in RGB images
where a secret message is embedded in the blue layer of certain blocks. In this algorithm …

In this paper we present a novel steganographic approach to increase the security of the
data hidden in a cover RGB image. Here we have used LSB insertion method that hides the …

In this letter, a novel steganographic method with four-pixel differencing and exploiting
modification direction is proposed. Secret data are embedded into each four-pixel block by …

A new image-based steganography technique-called triple-A algorithm is proposed in this
paper. It uses the same principle of LSB, where the secret is hidden in the least significant …

Abstract Background/Objectives: This paper presents a steganographic method by
calculating the pixel value differences along seven directions using nine-pixel blocks …

A novel approach to RGB channel based steganography technique is proposed. The RSA
algorithm is used for encryption and decryption. In an RGB image, each pixel (24 bits) is …

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 …
