Exploring Video Steganography for Hiding Images Based on Similar Lifting Wavelet Coefficients

Abstract

Abstract. This stegaphography is the science that attempts to hide the secret information through the cover media. It considers the combination of various issues such as security, privacy etc. This paper interests in the video steganography method, where the image is hidden in a video file. The approach uses the intensity features together with the lifting multiple discrete wavelet transform. The approach contains two steps. First, we bring the secret image and cover video file to transform using lifting based multi-level wavelet transform. Then we find the positions with the similar values from both secret image and video. The key idea is the finding of the position with the "same" or "similar" coefficients. We embed the image coefficients in those frame positions. In the experiments, we explore the efficiency of the method using various wavelet transforms with random coefficient and similar coefficient selections. The experiments also consider the different payload image size in the video file. For all the results, the proposed approach with similar coefficients and lifting multilevel wavelet transform has a better PSNR for all the test cases.

Novel video steganography algorithm based on secret sharing and error-correcting code for H.264/AVC

“…However, size limitations currently restrict the volume of information that can be hidden. For this reason, steganography based on digital video has recently been developed [13][14][15][16] . Compared with traditional media like digital images, the capacity of video is much greater, which makes video steganography very convenient, as well as offering greater redundancy and high communication quality and robustness.…”
