Multi-layers Video Steganography: A Novel Technique for Image Hiding

Abstract

Steganography is hiding of a secret message within an ordinary message. Both secret and ordinary data can be of different type such as document, digital image or digital video. As videos are transmitted more frequently over the internet we imposed a large impact on video steganography. In this work, we are presenting a novel video steganography technique to hide greyscale image inside a colored video. Our proposed technique consists of five stages that take the 6 most significant bits from each pixel of the secret image and hide it in different layers in the cover video using the least significant 2 bits from each color in each pixel in the selected frame. We proposed a selection procedure of video frames to improve the technique security. The experimental results are promising.

“…Therefore, they have very limited applicability. Nevertheless, LSBembedding is quite suitable for tasks in which there are no stringent requirements for resistance to certain types of attacks [9], [18]. The essence of LSB is to replace the last significant bits in the cover message (image, audio or video) with the secret message bits to be hidden.…”
