Information Hiding in Video files Using Frequency Domain

Eman A. E. Ahmed, Hassan H. Soliman, Hossam E. Mostafa

Video Steganography is a technique that is used to transmit information by modifying video frames in an imperceptible manner and depending on the weakness of the Human Visual System (HVS) in distinguishing the simple differences between colored images. This paper is about embedding encrypted information (texts and gray images) which have been encrypted using RSA technique at sender side in video frames; which are used as a cover. This embedding has been applied using two methods. The first is considered a parity Least Significant Bit (LSB) in the R - image (Red-image) of video frames and the second method was XORing of LSB for each pixel in the R - image (Red-image) of video frames and the bit next to it. The embedding has been applied in the frequency domain after applying Combined (Discrete Wavelet Transform - Discrete Cosine Transform) DWT-DCT Algorithm. First DWT2 for three times on each R-frame has been applied; and then these transformations followed by DCT2 for HH3 band and the quantization has been applied. The hidden data has been embedded in some coefficients in the middle sub-band. After embedding the dequantization has been applied and the inverse for all the transformations has been applied in reverse order to get a frame again in the spatial domain. Stego video has been reconstructed then has been sent over data network to the receiver who can extract the secret encrypted message after implementing the same procedure then decrypt it using the private key to get the secret message. The proposed system was tested using Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR) for different noise (salt and pepper) densities; which have been added as a sort of effective attack that may change the secret message.
