Reversible data hiding is the technique that allows embedding (hiding) data in an image
and later the hidden data as well as the exact copy of the image can be recovered at the …

Reversible data hiding (RDH) algorithms are concerned with concealing data within images
such that the original image can be fully recovered upon the extraction of hidden data. A …

Steganography is the science of hiding a message signal in a host signal, without any
perceptual distortion of the host signal. Using steganography, information can be hidden in …

Image steganography is one of the most well-known methods where a top-secret data is
embedded into the pixels of an image by altering some of its pixel values. Reversible image …

Reversible data hiding can embed secret data into the cover image to cheat hackers,
thereby avoiding the interception attack. The previous methods modify non-embeddable …

Recently, Luo et al. proposed a new block-based reversible data hiding method that divides
an image into blocks, sorts all pixels within a block and then chooses the middle sorted pixel …

In this paper, a new reversible data hiding scheme has been proposed using lagrange's
interpolating polynomial on interpolated sub-sampled images. First, we generate sub …

The technique of reversible data hiding recovers the original image without distortion from a
stego-image after the hidden data have been extracted. In this paper, we modify Zhao et al.'s …

Image steganography is technique which is used to hide information like audio, image, or
text in an image or video. Reversible-Data-Hiding (RDH) approach is the extensively used …

The technique of reversible data hiding recovers the original image from a stego-image
without distortion after the hidden data are extracted. A natural image usually contains …
