Steganography is the only answer for secure and secret communication. Existing methods in
image steganography focus on increasing embedding capacity of secret data. According to …

In a color image every pixel value composed of red, green and blue component and each of
which ranges from 0 to 255 in case of 8-bit representation. In this paper, we have used pixel …

Data Hiding is one of the challenging issues in the field of Network Security. Unlike
cryptography, Steganography is used to hide the existence of secret message by …

Steganography is a data-concealing technique that provides a covert communication. This
paper proposes a spatial domain color steganography method that uses a neighboring pixel …

In a gray scale image the pixel value ranges from 0 to 255. But when we use pixel-value
differencing (pvd) method as image steganographic scheme, the pixel values in the stego …

In this paper, we propose a new enhanced image steganography scheme for color images.
The proposed scheme is based on the pixel intensity of the cover image and the similarity in …

This paper proposes an image steganography approach based on pixel value differencing
and modulus function (PVDMF) to improve the peak signal-to-noise ratio (PSNR) and hiding …

An effective steganographic scheme is proposed that combines pixel-value differencing,
modulus function, and particle swarm optimization on the basis of previous research. In this …

The fundamental objectives of image steganographic algorithm are to simultaneously
achieve high payload, good visual imperceptibility, and security. This paper proposes a new …

In this paper, a steganographic method is presented for hiding data in images. This method
uses the modified least significant bits (MLSB) and modulus function with pixel value …
