Wavelet Based Color Video Steganography

Abstract

This paper describes the algorithm developed with the aim to hide a secret color video sequence within another color video sequence. An approach to apply a wavelet transform in order to decompose the cover video sequence and then replace the less significant wavelet band with secret video frames has been implemented and tested. On the receiver side, process is reversed and the hidden color video recovered from stego color video. Proposed algorithm has been implemented using Mat lab and PSNR and MSE error metrics employed to evaluate the quality of both video sequences.
