In the past two decades, reversible data hiding (RDH), also referred to as lossless or
invertible data hiding, has gradually become a very active research area in the field of data …

The data hiding method embeds the data into covers such as video, audio, and images,
which are used for integrity authentication, media protection, communication covert …

This paper proposes a full fidelity watermarking on JPEG bitstreams. That is, without a
designated decoder/player, the watermarked bitstream can be decompressed to the original …

An efficient steganographic method is proposed for embedding secret messages into gray
scale and RGB colored images. In this paper, a wavelet domain steganography is adopted …

Reversible data hiding deals with the insertion of auxiliary information into a host data
without causing any permanent degradation to the original signal. In this contribution a high …

The advancement of Internet technology made the usage and distribution of multimedia
contents over Internet very simple. Digital watermarking and steganography are becoming …

An efficient steganographic method is proposed for embedding secret messages into gray
scale and RGB colored images. In this paper, a wavelet domain steganography model is …

We propose and evaluate different methods to signal position and size of encrypted RoIs
(Regions of Interest) in JPEG images. After discussing various design choices regarding the …

Objectives: This paper intends to propose a secure steganography approach in JPEG
compressed domain by providing more possibilities to analyzing the DCT coefficients in …

This paper presents a new Steganography technique, In this paper, we propose a new high-
capacity reversible data hiding method for JPEG-compressed images. This method is based …
