Steganography in MPEG Video Files using MACROBLOCKS

Digital communication has become an essential part of infrastructure now - a - days and the advancement in the field of digital communication in other sense has hiked the fear of getting the data snooped at the time of sending it from the sender to the receiver. So, Information Security is becoming an inseparable part of digital Communication. The steganography approach uses the flexible macroblock ordering featur e of H.264/AVC to hide message bits. The message to be hidden is encrypted using AES algorithm. The me ssage is hidden twice and predicted using the transitive, reflexive, symmetric properties. The proposed method here evades the copyright infringement and makes the stego video immune to steganalysis .
