基于alpha叠加的视频信息隐藏算法

Video information hiding algorithm based on alpha superposition

信息隐藏技术是通过将秘密信息隐藏在载体中形成载密文件,以实现保护秘密信息和载体的目的。由于互联网的飞速发展和视频数据的广泛分布,将秘密信息隐藏在互联网视频中进行传递,能够提高信息传递的时效性和秘密信息的隐蔽性。本文提出了一种基于alpha叠加的视频信息隐藏算法,通过alpha属性配置原始视频和叠加窗口视频,能够隐藏和恢复秘密信息。分别采用人眼分析、图像均方根误差和峰值信噪比分析、以及马氏距离分析三种方式对算法的隐蔽性进行了评价,结果表明该隐藏算法的原理简单,可隐藏的数据量大,信息隐藏效果好。

Information hiding technology is to form secret files by hiding secret information on the carriers,in order to protect secret information and carriers. Owing to the rapid development of the Internet and the wide distribution of video data,hiding secret information in Internet video can improve the timeliness of information transmission and the concealment of secret information. We proposed a video information hiding algorithm based on alpha superposition which can hide and restore secret information. by configuring the original video and overlay window video through the alpha property. Using the technology of human eye analysis,root mean square error,peak signal to noise ratio,and Mahalanobis distance to evaluate the concealment of the algorithm. The results show that the principle of algorithm is simple,the amount of data can be hidden and the information hiding effect is eminent.
