A Secure High-Capacity Video Steganography Using Bit Plane Slicing Through (7, 4) Hamming Code

Achievement of high-capacity data hiding using a digital media is an important research issue in the field of steganography. In this paper, we have introduced a novel scheme of data hiding directly within the video stream using bit plane slicing through (7, 4) Hamming code with the help of shared secret key. In the proposed scheme, a secret logo image is embedded within the cover video stream for authentication and ownership identification through Hamming code based video steganography. Each frame of secret video has been separated into individual three basic color blocks (R, G and B) and then partitioned into (3 × 3) pixel blocks. After that, each color block is sliced up into 4 bit planes starting from LSB plane. The pixels’ positions of cover images are randomly selected by Pseudorandom Number Generator (PRNG) using a shared secret seed value and data embedding performed using (7, 4) Hamming code. As a result, 36 bits secret data can be embedded within a (3 × 3) pixel block which is almost eight times greater than Ramadhan and Khaled’s scheme (Systems, applications and technology conference (LISAT), 2014 IEEE Long Island, 2014) [1]. Here, we achieve a high payload with good visual quality stego video. Furthermore, the video compression is lossless so the video file size is strictly preserved for post-data embedding.
