With the intrusion of internet into the lives of every household and terabytes of data being
transmitted over the internet on daily basis, the protection of content being transmitted over …

Image based steganography uses the images as the cover media. LSB is a commonly used
technique in this filed. Several scenarios of utilizing least significant bits within images are …

To provide higher embedding capacity without sacrificing the imperceptibility, a novel
steganographic technique based on nine-pixel differencing with modified Least Significant …

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 steganography is a technique of masking secret information (eg text, image, audio,
video etc.) in a cover image in order to protect the information from being modified or …

The secure communication of information is a major concern over the internet. The
information must be protected before transmitting over a communication channel to avoid …

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 …

This paper presents a novel steganographic method based on Least Significant Bit (LSB)
substitution and 8-neighboring Pixel Value Differencing (8nPVD) for gray scale image in …

In this chapter, we propose an improved image steganography method using the concept of
least significant bit (LSB) substitution and pixel value differencing (PVD). The major …

Steganography is the art and science of invisible communication by hiding secret
information into other sources of information like text, video, audio, image etc. In image …
