Video Steganography Using LSB Matching Revisited Algorithm
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 6
Abstract
Abstract: Video Steganography deals with hiding secret data or information within a video. In this paper, a spatial domain technique for LSB Matching Revisited algorithm (LSBMR) has been proposed, where the secret information is embedded in the cover frames. LSB Matching Revisited(LSBMR) algorithm selects the embedding regions according to the size of secret message and the difference between two consecutive pixels in the cover image. For embedding rates is lower , only sharper edge regions are used while keeping the other smoother regions as they are. In the proposed approach, LSB Matching Revisited algorithm is used to embed the secret message into the video. Hence large amounts of data can be embedded and also preserving higher visual quality of stego images at the same time.The proposed method is analyzed in terms of both Peak Signal to Noise Ratio (PSNR) compared to the original cover video as well as the Mean Squared Error (MSE) measured between the original and steganographic files averaged over all video frames.
