Steganography is the technique of hiding confidential information within a cover media in
such a way that a third party cannot discern the presence of the hidden message. In the …

Reversible data hiding, in which the stego-media can be reversed to the original cover
media exactly, has attracted increasing interests from the data hiding community. Recently …

In this paper we propose a reversible high capacity data hiding method applying on binary
images. Since a binary image has only two colours, black or white. It is a trade-off between …

Data hiding conceals the existence of secret information while cryptography protects the
content of messages. A reversible data hiding is an algorithm, which can recover the original …

Steganography is communicating in a way which hides the existence of the information. The
cover media can be any general digital format, such as, text, image, audio, video, etc. By …

This paper introduces a new lossless data hiding technique in which data is embedded after
block division using the pixel difference value. Embedding done after block division …

In this paper, we propose a reversible data hiding method based on pixel difference
histogram shifting and ripple strategy. Because the local area has similar pixel value …

Reversible data hiding has been a newly developed branch in data hiding researches. With
the definition, when the message is hidden into the original image by some means, the …

Steganography is a technique used to hide a message inside an image. Reversible
steganography aims at recovering cover image without distortions while extracting secret …

Reversible data hiding (RDH) is an important field in image processing which can be
implemented using interpolation method. Here, we have proposed a reversible data hiding …
