steganography is becoming popular, especially for adding undetectable identifying marks, such as author or copyright information. Existing stegography systems for video stegnography used simple techniques to hide the images into videos which can be easily decoded by using some decoding algorithms. Hence a novel video stegnography system must be made that can hide the image in the video in the more secure way so that attacker cannot decode the hidden message from the video. In the proposed work, Least Significant Bit (LSB) will be used to hide the image message into a video. Proposed system hide the image into each of the LSB of each color of each pixel of the input video frame. In the proposed system, from the input video a fame with maximum motion and intensity is extracted which is treated as the target frame for hiding message. In this target frame image will be hide using Least Significant approach. The resultant video becomes the stegno video. Reverse process is performed on the stegno video to extract the image file from that video file. The proposed system is tested on various input videos and various input images are used as message to hide in these videos. It is evaluated that the results of the proposed system are very satisfactory. Performance of the proposed system is also compared with the performance of the existing system and it is evaluated that the proposed system generates the better results in terms of PSNR and MSE than that of existing system.
