Reversible Data Hiding: Principles, Techniques, and Recent Studies

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.
