Currently, there is a fast growth of network multimedia systems and advancement in technologies. This, together with the distribution of the Internet, has paved the way to an increasing concern over online crimes particularly for information, music, film, images, books, and software. Multilevel security technology allows the availability of information and other media content with different classifications of security to the information systems. Integrated within this system is Digital Watermarking. This is defined as the process of using a digital image, audio clip, video clip, or other work of media within that work itself as a medium for hiding messages. This paper will provide an introduction of the multilevel security system that will be developed for real-time communication most especially on e-commerce transaction.
