Research of Video Steganalysis Algorithm Based on H265 Protocol
School of Mathematics and Computer Science, Jianghan University, Wuhan, Hubei, China
A new generation of video coding standard H265 has raised a public concern by relevant scholars from all walks of life since April 2010. High-definition video is characterized by huge data size, complex encoding structure, high real-time performance and so on. Therefore, to design encryption and decryption pro-gram according to the actual needs and combined with application scenarios is imperative. Video steganalysis algorithm is a key content of video steganalysis (VSA), and VSA is a key technology of video decryption.
This paper researches LSB matching VSA based on H265 protocol with the research background of 26 original Video sequences, it firstly extracts classification features out from training samples as input of SVM, and trains in SVM to obtain high-quality category classification model, and then tests whether there is suspicious information in the video sample. The experimental results show that VSA algorithm based on LSB matching can be more practical to obtain all frame embedded secret information and carrier and video of local frame embedded. In addition, VSA adopts the method of frame by frame with a strong robustness in resisting attack in the corresponding time domain.
Key words: video steganalysis / LSB matching / median filter / characteristic / secret information
