Hiding Encrypted Color Image within MPEG-2 Video


In any communication, security is the most important issue in today’s world.Lots of data security and data hiding algorithms have been developed in the lastdecade. Hiding data in digital videos makes possible to hide a great quantity ofinformation when compared to techniques used in images. This work presentsthe encryption process of an image with combination of bit and pixelpermutation technique depending on random key, and then steganographytechnique that hiding each bit of encrypted image in selected block 8*8pixels(selected block process depending on high blue color ratio), of the frameand can extracted that bit after compressed with mpeg-2. Experimental resultsshow the success of hidden extracted data from the sequence of frames, and alsoindicate the effectiveness of the implementation steganography compressedvideo with high security features
