Image Steganograpy via Video Using Lifting Wavelet Transform

Abstract

We study the steganography method which hides an image in the video. We transform the video and image the lifting multiple discrete wavelet transform [1]. The coefficients of both are compared and the proper position of the coefficients are selected to hide the secret image pixel. The heuristic considers the coefficients that have the similar values to that of secret images are used to hide. The experiments compare this approach to the random selection approach as well as the methods using discrete wavelet transform. Different payloads are also considered to study the effect of secrete image size to the cover video. The experiments show that the selecting the similar coefficients give better results than the random approach for such a wavelet transform.
