一种低修改率的视频隐写方法
Video Steganographic Method with Low Modification Rate
摘要
Abstract
In this paper, a video steganographic method based on motion vectors and matrix encoding is proposed to solve the problem of motion vectors modification too high. Use H.264 standard to edit video coding. A set of the motion vectors with magnitude greater than a predefined threshold are selected. And the secret messages are embed in the horizontal or vertical component of those motion vectors through the proper range of the phase angle. The matrix encoding technique is also utilized to decrease the modification rate of motion vectors. Experimental results show that this method has high supporter data utilization rate, low supporter data modification rate and computational complexity.关键词
