基于相邻像素差值的可逆图像信息隐藏软件

Adjacent pixel differences based reversible image data hiding software

针对当前秘密信息在网络传输中仍存在非法窃取和内容篡改等现状,文中利用相邻像素差值的方法以及直方图平移技术,设计并开发出一款可逆图像信息隐藏软件。该软件是在PyCharm开发环境下使用Python语言实现,具有对BMP和TIFF等格式的载体图像进行秘密信息隐藏、提取以及载体图像还原等功能。经软件测试,其结果显示该软件运行正常且稳定,各功能操作简单方便。

On the basis of the recent situation of illegal stealing and content tampering of secret information in network transmission,this paper designs and develops a reversible image data hiding software which uses the method of adjacent pixel difference and histogram translation technology.The software is implemented in Python language under PyCharm development environment,and has the functions of hiding and extracting secret information and restoring carrier images in BMP and TIFF formats.The software testing results indicate that the software runs normally and stably,and the operation of each function is simple and convenient.
