In image information hiding, steganography capacity and image quality are the key
indicators. Keeping the image intact with high embedding capacity is a major challenge in …

Abstract Information hiding is to protect the security of secret information during
transmission. This paper proposes a random sequential high-capacity hiding scheme based …

This article proposes a very high capacity steganography technique using differencing and
substitution mechanisms. It divides the image into non-overlapped 3 * 3 3× 3 pixel blocks …

In data hiding, pixel-value differencing and least significant bit are well-known techniques to
embed secret data. In this paper, a novel data hiding scheme is proposed to provide high …

The combination of pixel value differencing (PVD) and least significant bit (LSB) substitution
gives higher capacity and lesser distortion. However, there are three issues to be taken into …

Security in digital communication is becoming more important as the number of systems is
connected to the internet day by day. It is necessary to protect secret message during …

The steganographic scheme based on pixel value difference (PVD) embeds secret
information by modifying the value of pixel pair within the block. The embedding capacity …

Least significant bit (LSB) steganography is the most widely employed technique, as it
promises imperceptibility at low computational complexity while hiding the message in LSBs …

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 …

This paper proposes a new adaptive least-significant-bit (LSB) steganographic method
using pixel-value differencing (PVD) that provides a larger embedding capacity and …
