Reversible Data Hiding Based on Orthogonal Prediction Error Modification and Multilevel Histogram Shifting

Yet another but an incremental reversible data hiding- for an irreversible data safety

“…The PSNR and the embedding capacity values were found to be better than Li et al, (2011) [22] and Zhenfei zhao and Hao Luo (2012). [26] Inverse S order Block based …”

“…Information hiding techniques [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] can be classified into reversible [20] and irreversible information hiding [21]. In irreversible technique, extraction of the message alone is concentrated leaving behind the cover.…”

“…Li et al, (2011) [22] studied about reversible data hiding techniques on compressed BTC data. In 2012, Zhenfei zhao, Guangyu and Ruixu Guo (2012) [26] concentrates on multilevel histogram shifting to perform reversible data hiding. Liu et al, 2010 [21] carried over reversible text a watermarking technique which increases the quality of the image as well as the PSNR.…”

“…Many other reversible data hiding techniques [20][21][22][23][24][25][26] such as side-match prediction, exploiting spatial correlation between images, lossless robust reversible data hiding scheme, histogram shifting, histogram modification. Out of the various data hiding schemes, the encryption is the popular technique which is the process of modifying the secret data in such a manner that no one could read the data before decryption [17][18][19].…”

An Analysis of Reversible Data Hiding Techniques in Images

“…Zhenfei Zhaoet.al in (6) proposed a new reversible data hiding scheme grounded on orthogonal vaticination revision (OPT) and multilevel histogram shifting. Conclude fashion can give the stylish weights of a predictor.…”
