MP4Stego: steganography in MPEG-4 videos
Diego Fiori de Carvalho, Rudinei Goularte · International Journal of Advanced Media and Communication · 2009
Steganography in digital videos makes possible to hide a great quantity of information when compared to techniques used in images. However, direct image techniques cannot be simply applied to compressed videos because temporal compression add noise to the hidden information potentially making it useless. This work presents a steganography technique called MP4Stego, which explores the MPGEG-4 encoding standard in order to recover hidden information without lost. Some benefits of MP4Stego are: hiding of large amounts of data; reproducing the video having hidden data in non specialised players; its immunity, up to now, to stegoanalysis techniques.
