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 state-of-the-art works.

基于预测误差位平面压缩的加密图像可逆数据隐藏

作为一种可以防止原始图像信息和附加信息被泄露的技术，加密图像中的可逆数据隐藏（RDHEI）一直受到研究人员的广泛关注。如何进一步提高RDHEI方法的性能成为研究的重点。为此，本文提出了一种基于预测误差位平面压缩的大容量RDHEI方法。首先，为保留嵌入信息的空间，图像所有者重新排列并压缩预测误差的位平面。接下来，预订房间后的图像使用安全密钥进行加密。最后，信息隐藏装置将附加信息嵌入到预留房间中。本文充分利用了相邻像素之间的相关性。
