Abstract Information security is an important aspect of information. The importance of the
value of information in every aspect can result in attempts to transfer access or theft of data …

Steganography is the science and art of covert communication. Conversely, steganalysis is
the study of uncovering the steganographic process. The evolution of steganography has …

In steganography, secret data are invisible in cover media, such as text, audio, video and
image. Hence, attackers have no knowledge of the original message contained in the media …

Recently, Steganography is an outstanding research area which used for data protection
from unauthorized access. Steganography is defined as the art and science of covert …

This paper illustrates the various performance evaluation parameters of image
steganography techniques. The performance of a steganographic technique can be rated by …

In the recent past some steganography techniques by combining least significant bit (LSB)
substitution and pixel value differencing (PVD) have been proposed to improve upon the …

This paper proposes two pixel value differencing (PVD) steganography techniques by
considering adaptive ranges to improve the security. In the first technique, the image is …

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 article proposes bit flip** method to conceal secret data in the original image. Here a
block consists of 2 pixels and thereby flip** one or two LSBs of the pixels to hide secret …

To protect from pixel difference histogram (PDH) analysis and RS analysis, two hybrid image
steganography techniques by appropriate combination of LSB substitution, pixel value …
