In this paper, a modification of PVD (Pixel Value Differencing) algorithm is used for Image
Steganography in spatial domain. It is normalizing secret data value by encoding method to …

This paper proposes an image steganographic approach using the principle of pixel value
differencing (PVD) and modulo operation (MO). The major contributions of the proposed …

Several steganographic methods have been proposed based on pixel value differencing
(PVD) attempting to increase the embedding capacity without great loss in the perceived …

There has been a tremendous growth in Information and Communication technologies
during the last decade. Internet has become the dominant media for data communication …

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) …

Steganography involves hiding information in another media. PVD based steganography
techniques uses the difference between the pixel values of a pair directly to hide the …

Steganography is the art and science of hiding information by embedding data into cover
media. Numerous techniques are designed to provide the security for the communication of …

Image steganography is a method for secure data transfer over the internet using image.
Now-a-days, as internet is growing, information security is a major concern. In this paper, we …

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 …

Most of the steganography techniques, based on pixel value difference, use the difference
between the pixel values to hide the information. In this paper, an algorithm is proposed …
