________________________________________________________________ Dr. Jia Rao Date 1. INTRODUCTION With the advancement of the ages, man has greatly found the need to communicate through distances. Initially this being accomplished through snail-mail was not real enough. He wanted to communicate vital moments of his file, his thoughts through the usage of more realistic means by the usage of multimedia, which is nothing but audio and video, which helped to share interesting thoughts, interesting audio/video files among people. Sharing of such files often requires communicating through networks of computers, which is not always secure enough. It is often a requirement that the file being shared is only visible or usable by the intended recipient, sometimes it is also may be essential to disguise the intruder of the file being different than what it really is. And in some commercial purposes it also may be required that only parts of the communicated audio/video files are playable. This arouses the need to device a methodology to securely communicate these multimedia files and hence protect the intellectual property of multimedia from attacks arising out of a hostile network environment. 1.1. Aim and Objective of the project: Aim: To device a methodology by which the video and audio files are secured in time and space efficient manner. Objective: To device an encryption methodology that utilizes various available encryption techniques and helps secure multimedia data files in such a manner that securing only information in the frame data provides an effect of securing the file as a whole. This securing process is to be carried out in a manner so as to reduce the amount of time used up in securing the file.
