In recent years, several lossless data hiding techniques have been proposed for images.
Lossless data embedding can take place in the spatial domain or in the transform domain …

摘要 In 2006, Ni et al. proposed a reversible data-hiding algorithm based on histogram
modification that utilizes the zero points and maximum points of the histogram of an image to …

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 …

In reversible compressed image data hiding, the exact cover image is restored at
approximate efficient rate after extracting the secret data from the stego-image. The …

Due to recent developments in internet technologies secret message communication is
conducted electronically which created new needs, issues, and opportunities. In secret …

In this paper, we propose a simple reversible data hiding method in spatial domain for digital
images by exploiting the correlation characteristic of neighboring pixels in natural images …

A reversible information hiding scheme that is suitable for embedding small amounts of data
is proposed in this paper. The secret data are transformed to base-k data stream, and each …

High embedding capacity, low image distortion, and reversibility are desired factors of
information hiding systems. In this paper, we propose a novel reversible information hiding …

Steganography is the method of hiding secret data in other data, such as video or an image.
A reversible data hiding method can extract the cover image from a stego-image without …

Steganography is an art of covert communication. There are many steganographic
techniques which help in secret communication. Moreover, images are found as a better …
