摘要:

为进一步提升密文图像可逆信息隐藏算法性能,提出预测误差位平面联合编码无损压缩算法,可更充分地利用图像冗余,以预留更多可嵌入空间。图像所有者首先计算图像的预测误差,将预测误差位平面划分为相同大小的非重叠块,接着将其按块进行重新排列,利用游程编码和哈夫曼编码压缩重排后的比特流以预留空间。信息隐藏者在加密图像的预留空间中嵌入信息。在接收端,合法接收者能无损并可分离地提取信息和恢复图像。实验结果表明,所提算法充分利用位平面分布特性,获得了高嵌入性能,在BOSSbase和BOWS-2图像集中平均嵌入率达到3.763 bpp和3.642 bpp,比同类算法至少提升0.081 bpp和0.058 bpp。

Abstract:

To further improve the performance of reversible data hiding in encrypted image, an algorithm for lossless compression of the prediction error bit-plane using joint encoding was proposed, which could make full use of image redundancy and reserve more embedding room.Firstly, the image owner calculated the prediction error of the image and divided the prediction error bit-plane into non-overlapping blocks of the same size.Then, the prediction error bit-plane was rearranged according to blocks and the rearranged bitstream was compressed by run-length encoding and Huffman encoding to reserve room.The data hider embedded information in the reserved room of the encrypted image.At the receiving end, the legitimate receiver extracted information and recovered images losslessly and separately.Experimental results show that the proposed algorithm makes full use of the bit-plane distribution characteristics and achieves higher embedding performance.The average embedding rates in BOSSbase and BOWS-2 datasets reach 3.763 bpp and 3.642 bpp, which are at least 0.081 bpp and 0.058 bpp higher than the state-of-the-art algorithms.

Key words: reversible data hiding in encrypted image, prediction error, run-length encoding, Huffman encoding, bit-plane
