Query: Reversible Data Hiding in Encrypted Images Based on Bit-plane
  Compression of Prediction Error   As a technology that can prevent the information from being disclosed, the
reversible data hiding in encrypted images (RDHEI) acts as an important role in
privacy protection and information security. To make use of the image
redundancy and further improve the embedding performance, a high-capacity RDHEI
method based on bit-plane compression of prediction error is proposed in this
paper. Firstly, the whole prediction error is calculated and divided into
blocks of the same size. Then, the content owner rearranges the bit-plane of
prediction error by block and compresses the bitstream with the joint encoding
algorithm to reserve room. Finally, the image is encrypted and the information
can be embedded into the reserved room. On the receiver side, the information
extraction and the image recovery are performed separably. Experimental results
show that the proposed method brings higher embedding capacity than
state-of-the-art RDHEI works.
