Video Steganographic Algorithm Based on Motion Vector

Article Preview

Abstract:

Focusing on video steganographic, a method based on motion vector is proposed to solve the problem of low security and low quality of video after embedding. A set of the motion vectors with magnitude greater than a predefined threshold are selected. And the secret message is embedded in the vertical or horizontal component of those motion vectors through the proper range of the phase angle. Steganographic between the message and vector motion with pseudorandom sequence generated by key. Experimental results show that this method has low impact on cover video, and also has low computation cost, high anti-statistical properties based on motion vectors difference.
