Hiding sensitive information in a host image (or 2D signal) is a challenging task. Several
image steganography techniques have been proposed in recent years, which either have …

The big data era calls for image steganography with large embedding capacity and good
image quality. Previous methods described in the literature pay more attention to image …

In this paper, an image steganography method is proposed to overcome the limitations
associated with the most existing image steganography methods based on either spatial …

This paper proposes an image steganography technique based on the principle of pixel
overlapping to improve the embedding capacity (EC) and peak signal-to-noise ratio (PSNR) …

Steganography is the art of hiding data inside a carrier file in such a way that an intruder or
unwanted personnel is unable to detect the presence of data inside the carrier file. Audio …

Image steganography is a mechanism that imperceptibly conceals information in a cover
image while also enabling the concealed details to be reliably retrieved from that image. 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 …

Steganography is an art of hiding secret information on a cover medium through
imperceptible methodology. The three pillars on which a steganography algorithm should be …

An LSB-based image steganography algorithm hides information in the least significant bits
of the pixel intensities of a cover image. But such a method has a very low embedding …

A new high capacity method for spatial domain image steganography is introduced in this
paper. The proposed block-based and high capacity steganographic method is the …
