Most state-of-the-art halftone image steganographic methods measure the flipping distortion
according to the statistics of the image database but neglect the characteristic of a single …

This paper proposes a steganalysis technique for both grayscale and color images. It uses
the feature vectors derived from gray level co-occurrence matrix (GLCM) in spatial domain …

In this paper we propose an efficient data embedding algorithm for palette-based images by
quantising similar colours in the palette. Unlike previous algorithms, this method's rate …

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 …

Digital steganography is becoming a common tool for protecting sensitive communications
in various applications such as crime/terrorism prevention whereby law enforcing personals …

Some state-of-the-art binary image steganographic methods aim to generate stego images
with good visual quality, while others focus more on the statistical security of the anti …

This paper presents an image Steganography algorithm that can work for cover images of
multiple formats. Having a single algorithm for multiple image types provides several …

Image steganography is the art of hiding information into a cover image. This paper presents
a novel technique for Image steganography based on Block-DCT, where DCT is used to …

In this paper we present the color local complexity estimation based steganographic
(CLCES) method that is able of both preventing visual degradation and providing a large …

In halftone image data hiding, pixel pairs containing master pixels and slave pixels are
common operating units. In most previous researches, master pixels are selected at a set of …
