Sažetak
In this work we propose an algorithm for hiding information in an avi file. The avi file is splitted into its audio and video components. The audio is saved in a file and its parameters are not changed. In addition, the video is splitted into frames. The frame contains 24 images which are transformed by Discrete Wavelet Transform (DWT). By appliying the DWT we obtain four sub images each one with different band width. Once we have the frequencies splitted, places are chosen for hiding information. In this work the concealment is made inside another avi file. However, the procedure can be applied for any kind of information. The file to be hidden is splitted into audio and video. Both are concealed independently in the sub images from the original video. The video to be hidden is separated into its frequency components and only the lower ones are saved, while the others are deleted. The compressed version of the image to be concealed is inserted into the video’s sub images. Once the concealment has been done the Inverse Discrete Wavelet Transform (IDWT) is applied and the video is reconstructed again. To get the hidden information the same insertion process is made, and it applies the IDWT in the recover file.
