Information hiding refers to the process of inserting information into a host to serve specific
purpose (s). In this paper, information hiding methods in the H. 264/AVC compressed video …

The term, steganography, comes from Greek and means “covered writing”(Johnson and
Jajodia, 1998a; Petitcolas et al., 1999). The intent of steganography is to hide a message in …

Pixel value differencing (PVD) and least significant bit substitution (LSB) are two widely used
schemes in image steganography. These two methods do not consider different content in a …

Image steganography is a growing research field, where sensitive contents are embedded
in images, kee** their visual quality intact. Researchers have used correlated color space …

This study presents a new adaptive data-hiding method based on least-significant-bit (LSB)
substitution and pixel-value differencing (PVD) for grey-scale images. The proposed method …

Significant bit) based Steganography technique for images imparting better information
security. It presents an embedding algorithm for hiding encrypted messages in nonadjacent …

Many existing steganographic methods hide more secret data into edged areas than smooth
areas in the host image, which does not differentiate textures from edges and causes …

Abstract Information security relies mainly upon encryption, and in some cases,
steganography for an extra layer of security. Steganography is the science and art of secret …
