Since the inception of pixel value differencing (PVD) image steganography, it has drawn
considerable interest among the researchers of this field. However, most of the PVD based …

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 …

various image steganography techniques have been proposed. In this paper, a new
steganography technique for BMP image is investigated which performs the least noises in …

The increase of data communication globally requires secure exchange of private
information. Steganography is a common form of information hiding from an unauthorized …

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

This article presents a novel iterative method of palette-based image steganography that
minimizes the RMS error between an original image and its stego-image. The proposed …

The authors address the use of sparse representation to securely hide a message within
non‐overlapping blocks of a given colour image in the wavelet domain. All four sub‐images …

An effective color image steganography method based on the module substitutions is
proposed. In accordance with the base-value of the blocks, a variety of secret bits is …

Steganography is the practice of hiding information or data in a seemingly innocuous cover
medium, such as message, file, image, audio, and video. In the past decades, many …

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