Reversible data hiding methods can embed secret data into multimedia to prevent attacks
from hackers. Reversible data hiding methods based on multiple stego-images have been …

The basic requirements of the information hiding system are good visual quality, high hiding
performance and high steganography security. Reversible steganography can reconstruct …

Reversible steganography becomes a popular hiding problem in recent years. A reversible
steganographicmethod can reconstruct an original image without loss from the stego-image …

In this paper, we propose a reversible data hiding method of high embedding efficiency. By
referring to secret data, the method first applies Matrix Coding to determine the modified …

In this paper, we present a novel, reversible steganographic method, which can reconstruct
an original image effectively after extracting the embedded secret data. The proposed …

To provide both a high payload capacity and a good stego-image quality, a high payload
frequency-based reversible image hiding (HPFRIH) method was presented in this paper …

A reversible data hiding method allows recovery of the cover image after the secret data
have been extracted. In this paper, a novel reversible data hiding method is proposed using …

Reversible data hiding (RDH) is a technique that slightly alters digital media (eg images or
videos) to embed secret messages while the original digital media can be completely …

There have been discussed several data hiding techniques which can hide the secret data
in an image. However, after extracting the secret data some of the image information gets …
