An approach towards novel video steganography for consumer electronics

Videos have proven themselves to be the best medium to demand consumer attention. This has motivated the sharing of videos on Whatsapp, Facebook and other social media. Consumer electronics such as mobile phones, tablets and laptops are mainly used for video sharing. In this paper, a novel attempt is made to conceal a secret video in a cover video using the concepts of steganography and discrete wavelet transform, thus achieving the best of both worlds. Also, the proposed work is extended towards concealing two secret videos in a single cover video. The performance evaluation of proposed technique is reported in the paper. It is observed that the reconstructed videos have PSNR ranging from 74.30–90.12 dB and the PSNR of stego videos ranges from 68.66–70.80 dB. It is also observed that both, stego videos and reconstructed secret videos are visually indistinguishable from the original video.
