Reversible Data Hiding in Encrypted Images Based on Bit plane Compression of Prediction Error
As a technology that can prevent the information of original image and
additional information from being disclosed, the reversible data hiding in
encrypted images (RDHEI) has been widely concerned by researchers. How to
further improve the performance of RDHEI methods has become a focus of
research. To this end, this work proposes a high-capacity RDHEI method based on
bit plane compression of prediction error. Firstly, to reserve the room for
embedding information, the image owner rearranges and compresses the bit plane
of prediction error. Next, the image after reserving room is encrypted with a
serect key. Finally, the information hiding device embeds the additional
information into the reserved room. This paper makes full use of the
correlation between adjacent pixels. Experimental results show that this method
can realize the real reversibility and provide higher embedding capacity than
