The rapid growth of the Internet and digitized content made video distribution simpler. In recent years, as video technologies have been broadly used in TV, communications and multimedia, video security has been gaining in importance. Hence the need for video security is on the rise. The clasical techniques for data security are not appropiate for the current multimedia usage. As a result, we need to develop new security protocols or adapt the available security protocols to be applicable for securing the multimedia applications. Our scheme is a secure and efficient video encryption scheme, and can be well to the video protection. Although much video encryption technique has been develop but not give so much efficiency in terms of encryption and decryption process. In this book we give a method to generate a encrypted video by encrypted video frame. Based on novel secure video scheme, an effective and generalized scheme of video encryption. It is a matrix computation scheme which is uses a concept of video frame and xor operation. This work proves that proposed scheme can fully encrypt the video frame. Further we can extend our approach into a digital video stenography.
