Query: Reversible Data Hiding in Encrypted Images based on Pixel Prediction and
  Bit-plane Compression   Reversible data hiding in encrypted images (RDHEI) receives growing attention
because it protects the content of the original image while the embedded data
can be accurately extracted and the original image can be reconstructed
lossless. To make full use of the correlation of the adjacent pixels, this
paper proposes an RDHEI scheme based on pixel prediction and bit-plane
compression. Firstly, to vacate room for data embedding, the prediction error
of the original image is calculated and used for bit-plane rearrangement and
compression. Then, the image after vacating room is encrypted by a stream
cipher. Finally, the additional data is embedded in the vacated room by
multi-LSB substitution. Experimental results show that the embedding capacity
of the proposed method outperforms the state-of-the-art methods.
