Recently, more and more information has been transferred, distributed, and exchanged through the Internet, with the progress of broadband networking technologies and with the advent of new communication methods such as P2P content delivery. These technologies make it possible for our life to be more and more convenient. In the near future, high-value content such as privacy information, business intelligence, etc will be transmitted over the Internet. Under these situations, the roles of copyright management and protection technologies become bigger and bigger. There are a lot of technologies to protect digital information in network distribution environment. But, they are not perfect solutions so they may be cracked by improper users tomorrow.   In this paper, we propose a new content distribution model which is based on the concept that digital content should be freely distributed with advertisements. In this model, complete contents are not distributed but a half indication contents and the advertisement are distributed together. So complete content can't be distributed by crackers and, moreover, users can't skip the advertisements. We believe our proposal system can create sound digital network society.
