Reversible Data Hiding: Principles, Techniques, and Recent Studies
نویسندگان
چکیده
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. Afterwards, some of proposed algorithms in the field of RHD were investigated. They were: Lossless Compression and Encryption of Bit-Planes by Fridrich et al., Reversible Data Hiding at Low Pixel-Levels by Mehmet et al., Based on Integer Wavelet Transform by Xuan et al., High Capacity Watermarking Based on Difference Expansion by Tian, and Reversible Data Hiding by Histogram Shifting by Ni et al. All of nominated algorithms are investigated in details to present a good comparative approach to existing methods. Key word: Reversible data hiding, data hiding, data security, RHD, PWLC, DHTC

متن کاملAn Overview of Reversible Data Hiding Schemes based on Difference Expansion Technique
Reversible data hiding is a type of data hiding techniques whereby the host image can be recovered exactly. Being lossless makes this technique suitable for medical and military applications. Difference expansion (DE) is one of the most important techniques which are used for reversible data hiding. This technique received more attention over the years because of its high efficiency and simplic...

Data security and data integrity are the two challenging areas for research. There are so many research is progressing on the field like internet security, steganography, cryptography. Data hiding are a group of techniques used to put a secure data in a host media with small deterioration in host and the means to extract the secure data afterwards. Reversible data hiding is a technique to embed...
متن کاملReversible Data Hiding
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 ...
