Hiding encrypted color image within MPEG-2 video

الملخص EN

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 last decade.

Hiding data in digital videos makes possible to hide a great quantity of information when compared to techniques used in images.

This work presents the encryption process of an image with combination of bit and pixel permutation technique depending on random key, and then steganography technique that hiding each bit of encrypted image in selected block 8 * 8 pixels (selected block process depending on high blue color ratio), of the frame and can extracted that bit after compressed with mpeg-2.

Experimental results show the success of hidden extracted data from the sequence of frames, and also indicate the effectiveness of the implementation steganography compressed video with high security features.
