Abstract
Steganography is essential in secure data exchanging and other numerous types of applications, therefore; it has become one of important fields to researchers. Steganography is the process of implanting secret information in an information cover without causing severe degradation neither to the cover information nor the secret information implanted in the cover. Most of the steganography techniques are applied on images, texts and protocols. In this paper a new technique of video steganography is proposed to implant a secret video data in to a cover video data using YCbCr color space and dynamic least significant bit algorithm (DLSB). The Least significant bit algorithm is used to hide text data in image or hiding an image in image data but this paper will propose a new technique which will utilize the LSB dynamically in embedding video clip in video data. The performance of the proposed algorithm has been gauged by peak signal to noise ratio (PSNR) for the stego, cover and secret videos while most of the papers which deal with steganography show the PSNR for the stego image only. The paper also shows reconstructed frames of the videos conducted by the algorithm. The results articulate that the algorithm is a good new method for video steganography
