Reversible Data Hiding
نویسنده
چکیده
Reversible data hiding, in which the stago-media can be reversed to the original cover media exactly, has attracted increasing interests from the data hiding community. In this study, the existing reversible data hiding algorithms, including some newest schemes, have been classified into three categories: 1) Those developed for fragile authentication; 2) Those developed for achieving high data embedding capacity; 3) Those developed for semi-fragile authentication. In each category, some prominent representatives are selected. The principles, merits, drawbacks and applications of these algorithms are analyzed and addressed.

PE Expansion-Based Reversible Data Hiding without Location Maps
This paper proposes a prediction error expansionbased reversible data hiding method using no location map. Though a reversible data hiding method once distorts an image to hide data into the image, the distorted image is completely separated to the original image and the hidden data. The proposed method uses only one parameter to extract data; this method extracts data without any location map,...

In this paper, we are going to have a survey on one of data hiding techniques called "Reversible Data Hiding (RDH)". Due to this, basic principles and notions of RHD are introduced. Also, primary techniques as the principles of RHD are talked. They are: Pair-Wise Logical Computation (PWLC) data hiding technique and Data Hiding by Template ranking with symmetrical Central pixels (DHTC) technique...

Reversible data hiding is defined as the process of hiding secret data in such a way that at receiver side both secret message and cover image can be recovered. This kind of reversibility is req...
متن کاملReversible data hiding based on histogram modification of difference images by s-type and Hilbert curve scanning
Reversible data hiding technology has currently attracted great attention recently. Using reversible data hiding methods, original cover images can be recovered losslessly from the cover image embedded information. In this paper, spatial reversible data hiding schemes based on histogram modification of difference images are discussed, in which the pixel gray values of difference image are alter...
متن کاملReversible Data Hiding and its Methods: A Survey
Hiding information destroys the host image even though the distortion introduced by hiding is imperceptible to the human visual system. Reversible data hiding techniques are designed to solve the problem of lossless embedding of large messages in digital images so that after the embedded message is extracted, the image can be restored completely to its original state before embedding occurred. ...
متن کاملHigh Efficiency Reversible Data Hiding for Two-stage Vector Quantization Compressed Images
Data hiding is a booming technique aiming to embed secret data into digital media for content authentication, annotation or copyright protection. Reversible data hiding is a special type of data hiding technique that guarantees the host digital media can be losslessly recovered after the secret data are correctly extracted. In the past several years, some reversible data hiding schemes for Vect...
