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 …

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

The least-significant-bit (LSB)-based approach is a popular type of steganographic
algorithms in the spatial domain. However, we find that in most existing approaches, the …

with the rapid advance in digital network, information technology, digital libraries, and
particularly World Wide Web services, many kinds of information could be retrieved any time …

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 …

Embedding a secret message into the pixels of a cover image yields a visual distortion if
these pixels belong to smooth regions. Thus, this prompted the development of some edge …

Steganography is an important secret information communication technology in which one
may send messages without others having knowledge of their existence. This paper …

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 …

The fundamental objectives of image steganographic algorithm are to simultaneously
achieve high payload, good visual imperceptibility, and security. This paper proposes a new …

The importance of image steganography is unquestionable in the field of secure multimedia
communication. Imperceptibility and high payload capacity are some of the crucial parts of …
