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 novel steganographic method for hiding information within the
spatial domain of the gray scale image. The proposed approach works by dividing the cover …

Steganography is an important secret information communication technology in which one
may send messages without others having knowledge of their existence. This paper …

This paper proposed a new technique for image steganography using edge detection for
RGB images. There are lots of algorithms to hide data with precision level but they are also …

In this paper, a novel steganography algorithm based on an improved “Matrix Pattern”(MP)
method is presented. In this process, firstly, an RGB image is divided into the non …

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 …

Steganography is an important secret information communication technology in which one
may send secret data without others having knowledge of its existence. This chapter …

This paper presents a new algorithm for color image based steganography. Our algorithm
adaptively determines the number of secret message bits that each pixel of cover image can …

In this paper, we present a new algorithm for RGB image based steganography. Our
algorithm introduces the concept of storing variable number of bits in each channel (R, G or …

Steganography is the art of hiding the fact that communication is taking place, by hiding
information in other information. In this paper we have investigate two methods of RGB …
