| Abstract | ||
| Video Steganography deals with hiding secret data or information within a video. In this paper, a modified or dynamic based least significant bit (LSB) technique has been proposed to hide movie in movie. A dynamic LSB is a spatial domain technique where the secret information such as images, or video is embedded in the LSB of the cover movie (i.e frames) by selecting number of bits to be embedded. The idea of the proposed method is take away the least significant pixels from one image (frame) which is in cover movie and uses them to store most significant pixels of second image (frame) which is in hidden movie. The hidden image’s (frame’s) values are stored in the result frame’s least significant bits so they don’t add greatly to the resulting combined video(movie). The proposed method is analyzed in terms of both Peak Signal to Noise Ratio (PSNR) compared to the original cover video with stegano video as well as the Mean Square Error (MSE) measured between the original and steganographic files averaged over all video frames. | ||
