HASH BASED LEAST SIGNIFICANT BIT TECHNIQUE FOR VIDEO STEGONAGRAPHY(HLSB)

Video Steganography deals with hiding secret data or information within a video. In this paper, a hash based least significant bit (LSB) technique has been proposed. A spatial domain technique where the secret information is embedded in the LSB of the cover frames. Eight bits of the secret information is divided into 3,3,2 and embedded into the RGB pixel values of the cover frames respectively. A hash function is used to select the position of insertion in LSB bits. The proposed method is analyzed in terms of both Peak Signal to Noise Ratio ($PSNR$) compared to the original cover video as well as the Mean Square Error ($MSE$) measured between the original and steganographic files averaged over all video frames. Image Fidelity ($IF$) is also measured and the results show minimal degradation of the steganographic video file. The proposed technique is compared with existing LSB based steganography and the results are found to be encouraging. An estimate of the embedding capacity of the technique in the test video file along with an application of the proposed method has also been presented..
