Abstract

The art of video steganography is a promising tool in the science of secret communication by hiding the information in the cover video without any detectable changes in the cover file. The dynamic nature of the video format makes it immune to cyber-attacks which in turn helps in secret communication. As the attention to video file sharing is rapidly growing, it is vital to have enhanced and novel steganographic techniques.
New approaches have been suggested to cover the hidden message in a video file with the proposed technique in this article. The confidential data is disguised by shielding them in the 7th bit of the identified pixel and the following pixel. Whereas the pixel in which the secret data should be shielded is picked using a knight tour algorithm that applies an added security to the secret message from cyber trespassers.The competence of this novel algorithm is proved by enumerating various parameters such as PSNR, MSE, SSIM, and embedded capacity.

Key words: Video Steganography, Knight Tour, 7th bit model, embedded capacity, Robustness
