A hybrid approach for video steganography using edge detection and identical match techniques

摘要

To maintain the secrecy of information, various information hiding techniques are used. Steganography is one of them, which means hide information inside another digital media like text, image, audio, video etc. without being detected by human visual system (HVS). Recently Video steganography has become a strong tool to hide large amount of data rather than image steganography. This paper is proposing an idea about a hybrid approach for video steganography to achieve high capacity data & high quality of stego video on the basis of quality metrics like PSNR, MSE and BER. The proposed methodology is a combo pack of various techniques such as RSA encryption, Edge detection, Identical Match and 4LSB substitution, in which a video file will be used to hide text message inside in all layers of RGB color frames of video. The experimental results are analyzed on MATLAB software on cover video of `rhinos' and text secret message is embedding inside the video. The resulting values show that our proposed algorithm has high imperceptibility and security and resists the visual attacks.
