基于直方图平移的安全可逆信息隐藏算法

可逆信息隐藏技术可以在提取隐藏的秘密信息之后完全恢复原始的载体信息,具有重要的理论意义和广阔的应用前景。基于直方图平移的可逆信息隐藏技术需要额外传送一部分信息,会带来较大的通信负担和安全隐患。通过对载体图像进行分块,并引入密钥,提出了一种基于直方图平移的安全可逆信息隐藏算法,不需要单独传送任何额外信息就能实现秘密信息提取和原始载体的无损恢复。能够有效弥补传统算法的缺陷,降低通信负担,同时具有较高的安全性。理论分析和实验仿真表明该算法具有较好的实用性能。

A Security Reversible Information Hiding Algorithm Based on Histogram Shifting

The reversible information hiding technology can completely recover the original carrier information after extracting the hidden secret information, which has important theoretical significance and broad application prospect. The reversible information hiding technology based on histogram shift needs to transmit some additional information, which will bring greater communication burden and security risks. A reversible information hiding algorithm based on histogram shift with secret key was proposed. The carrier image was partitioned reasonably and the secret information could be extracted and the original vector could be restored without any extra information. This algorithm can effectively compensate the defects of traditional algorithms and reduce the communication burden, with the high level security. Experimental results show that the algorithm has good performance.
